Error no such device grub rescue windows 10

Некоторые пользователи, которые ранее настроили свои компьютеры на двойную загрузку дистрибутивов Windows и Linux (чаще всего с Ubuntu), сообщают, что их

Некоторые пользователи, которые ранее настроили свои компьютеры на двойную загрузку дистрибутивов Windows и Linux (чаще всего с Ubuntu), сообщают, что их компьютер входит в режим восстановления Grub и отображает ошибку Нет такого раздела — Grub Rescue.

Ошибка Нет такого раздела — Grub Rescue

После тщательного изучения этой конкретной проблемы выясняется, что существует несколько различных ситуаций, которые могут вызвать появление этой проблемы. Вот список потенциальных виновников, которые могут нести ответственность за эту проблему:

  • Загрузчик GRUB поврежден или удален — если вы видите эту ошибку из-за какого-либо типа поврежденных данных, связанных с загрузчиком GRUP, или после того, как вы неохотно удалили связанные с ним данные, вы можете решить проблему, вручную перенастроив утилиту для загрузки с помощью правильные файлы.
  • Загрузчик неправильно настроен или поврежден. Поскольку эта проблема также может возникать из-за неправильно настроенных или поврежденных данных BCD, вы сможете решить эту проблему, перестроив данные конфигурации загрузки из командной строки с повышенными привилегиями.
  • Текущая конфигурация загрузки несовместима — если проблема вызвана неверными данными, которые загружаются в загрузчик GRUB, вы можете решить проблему, используя резервную копию реестра, чтобы восстановить ваш компьютер до хорошей конфигурации.

Теперь, когда вы знаете всех потенциальных виновников, вот список методов, которые другие затронутые пользователи успешно использовали для решения проблемы и предотвращения загрузки своего компьютера в режим восстановления Grub:

Безусловно, наиболее эффективное исправление, с которого вам следует начать, поскольку оно наименее разрушительно — это вручную перенастроить загрузчик GRUB и убедиться, что приоритет отдается основной ОС.

Несколько затронутых пользователей подтвердили, что им наконец удалось обойти состояние восстановления GRUB, выполнив ряд инструкций, предназначенных для ручной перенастройки загрузчика GRUP для определения приоритета основной ОС.

Если этот сценарий применим, следуйте приведенным ниже инструкциям, чтобы сделать это непосредственно через меню восстановления GRUB:

  1. Когда ваш компьютер войдет в режим восстановления GRUB, введите следующую команду и нажмите Enter, чтобы просмотреть все доступные разделы: ls
  2. После того, как вы это сделаете, вы должны получить обзор всех разделов, которые в настоящее время есть на вашем основном диске. На этом этапе вам необходимо убедиться, что вы выбрали основную ОС. В нашем случае правильный раздел (hd0, msdos2), поэтому мы использовали следующую команду для опроса раздела: ls (hd0, msdos2)

    Примечание. Убедитесь, что вы заменили раздел правильным примером в вашем случае. Если вы получили сообщение вроде «Файловая система — это ext2 или ext3», вы правильно определили раздел, в котором находится ваша основная ОС.
    Примечание 2: Если вы опрашиваете раздел и получаете сообщение «Файловая система неизвестна», вы выбрали неправильный раздел.

    Сообщение об ошибке неправильного раздела в GRUB

  3. После выбора правильного раздела введите «set» и нажмите Enter, чтобы запросить и получить окончательный список вашего основного раздела.
  4. Затем введите следующие команды и нажмите Enter после каждой команды, чтобы изменить приоритет загрузчика GRUB на правильный: set boot = (hd0, msdos5) set prefix = (hd0, msdos5) / boot / grub insmod normal normal
  5. После того, как вы введете последнюю команду, вы попадете в главное меню GNU Grub. Как только вы попадете на этот экран, просто выберите ОС, с которой вы хотите загрузиться, и нажмите Enter.
    Загрузка с основного раздела в GRUB

В случае, если этот метод не сработал для вас и последовательность загрузки в конечном итоге загрузится с той же ошибкой No such Partition -Grub Rescue, вернитесь к следующему потенциальному исправлению ниже.

Метод 2: восстановление файлов данных конфигурации загрузки (BCD)

Если первый метод не сработал для вас, следующим шагом будет использование утилиты данных конфигурации загрузки (BCD), чтобы найти установочные файлы Windows на всех дисках и добавить их обратно в список загрузки, чтобы последовательность загрузки могла найти это во время запуска.

Этот метод успешно использовался многими пользователями, которые ранее сталкивались с ошибкой No such Partition — Grub Rescue. Восстановление кластеров файлов BCD позволило им нормально выполнять двойную загрузку без принудительного входа в меню восстановления GRUP.

ВАЖНО! Этот метод потребует от вас подключения совместимого установочного носителя Windows. Если у вас его нет наготове, вы можете создать установочный носитель Windows с нуля и загрузить его на USB-накопитель.

Выполнив все требования, следуйте приведенным ниже инструкциям:

  1. Подключите USB-накопитель с установочным носителем и запустите компьютер обычным способом, нажав кнопку питания.
  2. Для доступа к кнопке настройки нажмите соответствующую кнопку в зависимости от производителя вашей материнской платы.Доступ к меню настройки BIOS / UEFI

    Примечание: ключ настройки будет отличаться от производителя к производителю. Чаще всего клавиша настройки представляет собой одну из клавиш F (F2, F4, F6, F8), клавишу Esc или клавишу Del (на компьютерах / ноутбуках Del). Если у вас возникли проблемы с доступом к меню настройки, поищите в Интернете конкретные инструкции по доступу к нему.

  3. Как только вы войдете в меню «Настройка», перейдите на вкладку «Загрузка» и убедитесь, что USB-накопитель, содержащий установочный носитель, установлен как вариант загрузки №1.Загрузка с установочного носителя
  4. Сохраните изменения, затем перезагрузите компьютер, дайте компьютеру загрузиться с установочного носителя и дождитесь загрузки установочных файлов.
  5. Когда вы перейдете на первую страницу, нажмите «Далее», затем нажмите «Восстановить компьютер» в правом нижнем углу экрана.Ремонт компьютера с установочного носителя
  6. Затем дождитесь загрузки меню «Восстановление», затем выберите «Устранение неполадок» и нажмите «Командная строка» в списке доступных параметров:Доступ к командной строке через меню восстановления

    Примечание. В некоторых версиях Windows 10 вы также можете загрузиться из меню «Восстановление», вызвав 3 последовательных прерывания системы во время процедуры запуска.

  7. Как только вы войдете в командную строку с повышенными привилегиями, введите следующую команду и нажмите Enter, чтобы исправить зависимости MBR, связанные с вашей установкой Windows: bootrec / fixmbr
  8. После успешной обработки команды введите следующие команды и нажмите Enter, чтобы исправить данные конфигурации загрузки, связанные с вашей установкой Windows: bootrec / fixboot

    Примечание. Если вы получаете сообщение об ошибке «Доступ запрещен» при вводе одной из двух вышеперечисленных команд, следуйте этим инструкциям, чтобы решить проблему с доступом к bootrec.

  9. Затем введите следующую команду и нажмите Enter, чтобы просканировать все ваши диски на наличие установочного носителя Windows: bootrec / scanos

    Примечание. Эта операция может занять некоторое время в зависимости от размера ваших разделов. Не закрывайте это окно до завершения операции.

  10. Если операция завершена успешно, введите следующую команду для эффективного восстановления данных конфигурации BCD: bootrec / rebuildbcd
  11. Когда вас попросят подтвердить, введите Y и нажмите Enter, чтобы подтвердить и начать операцию.Подтвердите операцию построения файловой системы BCD
  12. Наконец, введите «exit» и нажмите клавишу «Ввод», чтобы выйти из командной строки с повышенными привилегиями и позволить Windows нормально загрузиться.

В случае, если конечный результат такой же (попытка загрузки заканчивается той же ошибкой «Нет такого раздела»), перейдите к следующему способу ниже.

Метод 3: Использование резервной копии реестра для восстановления последней удачной конфигурации

Если ни один из вышеперечисленных методов не помог вам, возможно, вы сможете исправить текущую конфигурацию с помощью последней удачной резервной копии, которая должна позволить вам без проблем выполнять двойную загрузку.

Для этого вам потребуется использовать меню «Дополнительные параметры», чтобы открыть командную строку с повышенными привилегиями и выполнить ряд команд, которые позволят вам загрузиться с использованием последней удачной конфигурации.

Сообщается, что этот метод успешно использовался многими пользователями, столкнувшимися с ошибкой No such Partition -Grub Rescue.

Чтобы использовать резервную копию реестра для восстановления последней удачной конфигурации, следуйте приведенным ниже инструкциям:

  1. Вставьте совместимый установочный носитель Windows и загрузитесь с него, нажав любую клавишу при появлении соответствующего запроса.Загрузка с установочного носителя

    Примечание. Если у вас нет совместимого установочного носителя или ваша система не загружается с него, выполните шаги с 1 по 4 из метода 2.

  2. Как только вам удастся успешно загрузиться с установочного носителя, нажмите «Восстановить компьютер» в нижнем левом углу экрана.Ремонт вашего компьютера
  3. Когда вы, наконец, войдете в меню Advanced Recovery, нажмите «Устранение неполадок», затем нажмите «Командная строка» в списке доступных параметров.Доступ к командной строке через меню восстановления
  4. Как только вы войдете в командную строку с повышенными привилегиями, введите «C:» и нажмите клавишу ВВОД, чтобы получить доступ к разделу, в котором вы установили Windows. Если вы установили Windows на другой раздел, замените букву соответствующим образом.
  5. Затем введите «dir» и нажмите Enter, чтобы получить доступ к корневому каталогу диска с ОС.
    Примечание. Перед тем как продолжить, рекомендуется создать резервную копию текущего реестра. Для этого введите следующую команду и нажимайте Enter после каждой команды: cd windows system32 config MD backup copy *. * BackupРезервное копирование реестра
  6. Затем введите следующие команды и нажмите Enter, чтобы получить доступ к последней удачной конфигурации и изменить поведение по умолчанию для загрузки с нее: CD regback copy *. * ..
  7. Когда появится подсказка, нажмите A и еще раз нажмите Enter.
  8. Наконец, введите exit и нажмите Enter, чтобы выйти и нормально загрузиться. Это приведет вас в главное меню GRUP, где вы сможете выполнить двойную загрузку по своему усмотрению.

You may ask me what the specific factors are causing such a problem on your computer. Here we will give a detailed analysis of this error to you.

1. Generally speaking, the most common reason for this error is a misconfigured boot loader file. While installing Ubuntu in Windows, a part of Grub lives in the Master Boot Record (MBR), and the other parts live in the Linux boot partition.

This means that although the Ubuntu partition is deleted, Grub is still in MBR. In addition, the active partition is not correctly set. As a result, you will receive the error of «no such partition grub rescue» during your Windows 10 operating system startup.

2. When resizing Ubuntu partition,UUID is modified, so that Grub can’t read the boot information.

3. When reinstalling Ubuntu system, you may install it to a new partition. Although the original partition has been formatted, you haven’t reinstalled Grub 2.

4. While restoring to Ubuntu 8.X, the Grub is version 1. So, Grub 2 is damaged.

Suggestion: Back up Your PC to Avoid System Breakdown

After fixing Windows 10 error no such partition, it is better to back up your operating system so that you can restore the PC to a previous state in case you face any system issue.

No Such Partition Grub Rescue Windows 10 FAQ

How do I fix no such partition grub rescue?

  1. Rebuild MBR with MiniTool Partition Wizard
  2. Rebuild BCD Files with Windows 10 Automatic Repair
  3. Restore the Boot Sector Code with Windows 10 Automatic Repair
  4. Manually Configure the Active Partition

How do I fix grub after installing Windows 10?

There are two ways you can fix grub after installing Windows 10: Run Boot Repair and Reinstall GRUB. This post — Windows 10 deleted GRUB [FIXED BY EXPERTS] gives much information to you.

How do I get into grub rescue mode?

To know how to get into grub rescue mode, you can follow these steps in the wiki article – Recovery Mode.

How do I manually rebuild my BCD?

Open Command Prompt and use these commands: bootrec /fixmbr, bootrec /fixboot, bootrec /scanos and bootrec /rebuildbcd.

Sometime you may encounter error messages like Error: no such device: xxxxx-xxxx-xxxx-xxxx-xxxxx  right after powering up the PC.

Such problems are caused by misconfigured GRUB, unable to load any operating system.

Usually happens when you resize, rename or shrink the disk partitions. Or may be even if you transfer a perfectly working hard drive from one PC to another.

But there’s an easy solution to deal with such problems, and here we’ll discuss about it.

Why this is happening?

This grub no such device problem usually happens when the boot drive’s UUID is changed somehow.

Like if you convert a disk drive with MBR partition table to GPT partition table. Another reason of UUID change is if you resize, merge, shrink or extend the linux root partition.

Here GRUB is present as bootloader, but it can’t find the proper modules and configuration file due to changed partition UUID.

To fix this problem, you’ve to determine three things.

First which one is the linux root( / ) partition, second how the system is booted, i.e. in UEFI mode or in legacy BIOS mode.

Third, if it’s booted in UEFI mode, then which is the EFI system partition?

You can use the parted command to determine the ESP partition, which is a FAT32 filesystem of around 100MB.

sudo parted /dev/sda print

Now the actual steps to fix the error no such device problem.

  1. Use the ls command on the grub rescue prompt to list all the partitions.
  2. Then you can use the ls command again to check the contents of each partitions to be sure.
    ls (hd0,1)/

    The linux root partition will contain /bin , /boot, /lib etc. etc directories.

  3. If you’re sure about the linux root partition, then type the commands listed below one by one. In my case, the partition is (hd0,msdos5) .
    set root=(hd0,5)
    set prefix=(hd0,5)/boot/grub
    insmod normal
    normal
  4. Then you should be able to access the GRUB boot menu like before, select the linux distro and boot to it.
  5. After booting, you must be asked to login to your user account.
  6. Next login to the account and open up a terminal window.
  7. Then determine if the system is booted with UEFI mode or legacy BIOS mode, use the one liner script below.
    [ -d /sys/firmware/efi ] && echo "UEFI boot" || echo "Legacy boot"
  8. To reinstall GRUB for legacy BIOS use this command.
    sudo grub-install /dev/sda --target=i386-pc
  9. To re install GRUB on a UEFI based system, use this.
    sudo mount /dev/sda2 /boot/efi     # mount the EFI system partition
    sudo grub-install /dev/sda --target=x86_64-efi --efi-directory=esp
  10. If grub installation reports no problem, then update the GRUB configuration file.error no such device grub rescue
    sudo update-grub
  11. Finally reboot the PC or laptop to check the if it worked at all or not.

Also don’t just copy-paste the commands, your EFI system partition could be different, most probably /dev/sda1 .

Conclusion

It’s not a very well described tutorial to fix the grub rescue no such device issue. But I hope you’ve got basic the idea to deal with the error no such device issue.

First you need to boot linux somehow then reinstall the GRUB bootloader and update the GRUB configuration. Here’s the detailed GRUB rescue tutorial.

If you’ve any question or suggestion, leave comments below.

After an installation of Ubuntu 12.04, erasing an old partition with Ubuntu 10.10, I can’t get grub to load. I can’t access my Windows 7 partition either

I get the message:

> error: no such device: 58ABF29C...  
grub rescue>

I suppose my master boot record got erased/corrupted. How can I check and fix this?

Re-install your GRUB.

  1. Boot using a live cd of ubuntu.

  2. Open a terminal and run the command
    sudo fdisk -l
    It lists the complete partition table of the hard disk. In there, identify which partition you have got your linux installed on. You can identify it using the drive size you had allocated for it and looking at the last column of the output which will be extended or Linux for all of your linux partitions. The partition will most probably be something like /dev/sda5 or something. Remember this partition.

  3. Create a temporary folder in your home directory (Note: You can make the temporary folder anywhere you want. I’m using the home folder just for the sake of explanation). I’m calling it temp for now. So that temp folder’s path will be/home/ubuntu/temp`.

  4. Mount your linux partition there. That is, assuming that you found your linux partition to be /dev/sda5, you mount that at the temp folder by doing the following command

    sudo mount /dev/sda5 /home/ubuntu/temp

  5. If you want to check whether you have mounted the correct partition, go to your home folder and open temp. You will be in the / directory. In there you will find home, in which your home folder’s name will be there. Once you’ve confirmed you have mounted the correct partition, do step 6.

  6. You have to install grub by showing the system where to read the data from the hard disk at the beginning. Don’t worry, just run the following command

    sudo grub-install --root-directory=/home/ubuntu/temp /dev/sda

    The /dev/sda corresponds to your hard disk name. Replace it by whatever the command sudo fdisk -l command showed you.

  7. You’re done. You may restart your system.

I had the same problem while upgrading 10.10 to 12.04 on an ASUS EEEPC.

Previously, I had / mounted on the 4GB disk and /home on the 12GB disk. The latest Ubuntu needs at least 4.8GB in /, so I needed to swap the mount points.

I fixed the problem by changing the hard-disk boot sequence in my BIOS settings.

I had this same problem when I created my /boot as a RAID 1 mirror on Mint 13.

Solved, by using the install CD to boot back into the system. Then re-mount my drives and chroot into the installed system:

apt-get install mdadm lvm2

Not sure if this is really needed but I then did:

grub-install /dev/sda
grub-install /dev/sdb
update-grub

Some users that have previously configured their computers to dual-boot Windows and Linux distributions (most commonly with Ubuntu) are reporting that their PC is entering Grub Rescue Mode and displaying the error No Such Partition – Grub Rescue.

Error No Such Partition -Grub Rescue

After investigating this particular issue thoroughly, it turns out that there are several different situations that might trigger the apparition of this issue. Here’s a list of potential culprits that might be responsible for this issue:

  • GRUB Bootloader is Corrupted or Deleted – If you are seeing this error due to some type of corrupted data associated with the GRUP Bootloader or after you have unwillingly deleted data associated with it, you can fix the issue by manually reconfiguring the utility to boot using the correct files.
  • The bootloader is Misconfigured or Corrupted – Since this issue can also occur due to misconfigured or corrupted BCD data, you should be able to fix the issue by rebuilding the Boot Configuration data from an elevated Command Prompt.
  • Current Boot Configuration is inconsistent – In case the issue is being caused by bad data that’s being fed into the GRUB bootloader, you can potentially fix the issue by using a Registry Backup to restore your computer back to a good configuration.

Now that you know every potential culprit, here’s a list of methods that other affected users have successfully used to fix the issue and prevent their computer from booting into Grub rescue mode:

Method 1: Manually Reconfigure GRUB Bootloader

By far, the most effective fix and the one you should start with since it’s the least destructive is to manually reconfigure the GRUB bootloader and make sure that the primary OS is prioritized.

Several affected users have confirmed that they finally managed to bypass the GRUB rescue state by following a set of instructions designed to manually reconfigure the GRUP Bootloader to prioritize the main OS.

If this scenario is applicable, follow the instructions below to do so directly via the GRUB Rescue menu:

  1. Once your PC enters GRUB Rescue Mode, type the following command and press Enter to get an overview of all your available partitions:
    ls
  2. After you do this, you should get an overview of all partitions that you currently have on your primary disk. At this point, you need to make sure that you select the primary OS. In our case, the correct partition is (hd0,msdos2), so we used the following command to interrogate the partition:
    ls (hd0, msdos2)

    Note: Make sure to replace the partition with the correct example in your case. If you get a message saying something like ‘File System is ext2 or ext3‘, you have correctly identified the partition that holds your primary OS.
    Note 2: If you interrogate a partition and you get the message ‘Filesystem is unknown‘, you didn’t select the correct partition.

    Incorrect partition error message in GRUB
  3. Once the correct partition is selected, type the ‘set‘ and press Enter to interrogate and get a definitive listing of your main partition.
  4. Next, type the following commands and press Enter after each command to change the priority of GRUB Bootloader to the correct one:
    set boot = (hd0, msdos5)
    set prefix=(hd0, msdos5)/boot/grub
    insmod normal 
    normal
  5. After you input the final command, you’ll be taken to the main GNU Grub menu. Once you get to this screen, simply select the OS that you want to boot from and press Enter.
    Booting from the main partition in GRUB

In case this method didn’t work for you and the booting sequence eventually boots in the same No Such Partition -Grub Rescue error, move back to the next potential fix below.

Method 2: Rebuilding the Boot Configuration Data files (BCD)

If the first method didn’t work for you, the next step would be to use the Boot Configuration Data (BCD) utility to locate the Windows installation files on all disks and add them back to the boot list so that the booting sequence can locate it during startup.

This method was successfully used by a lot of users that were previously dealing with No Such Partition – Grub Rescue error. Rebuilding the BCD file clusters successfully allowed them to dual-boot normally without being forced into the GRUP Rescue menu.

IMPORTANT: This method will require you to plug in a compatible installation Windows installation media. If you don’t have one at the ready, you can create the Windows installation media from scratch and load it on a USB drive.

Once you meet all requirements, follow the instructions below:

  1. Plug-in the USB stick containing the installation media and start your computer normally via the power button.
  2. Access the Setup key by pressing the correspondent button depending on your motherboard manufacturer.
    Accessing the BIOS / UEFI Setup menu

    Note: The setup key will be different from manufacturer to manufacturer. Most commonly the Setup key is either one of the F keys (F2, F4, F6, F8), the Esc key, or the Del key (on Del computers/laptops). If you’re having trouble accessing the Setup menu, search online for specific instructions on accessing it.

  3. Once you’re inside the Setup menu, access the Boot tab and make sure to set the USB stick containing the installation media as Boot Option #1.
    Booting from the installation media
  4. Save the changes, then restart and allow your computer to boot from the installation media and wait for the installation files to load.
  5. Once you get to the first page, click on Next, then click on Repair your computer from the bottom-right corner of the screen.
    Repairing Computer via installation media
  6. Next, wait for the Recovery menu to load, then select Troubleshoot and click on Command Prompt from the list of available options:
    Accessing the Command Prompt via the Recovery menu

    Note: On certain Windows 10 versions, you might also be able to boot from the Recovery menu by forcing 3 consecutive system interruptions during the startup procedure.

  7. Once you’re inside the elevated Command Prompt, type the following command and press Enter to fix the MBR dependencies associated with your Windows installation:
    bootrec /fixmbr
  8. Once the command is processed successfully, type the following commands and press Enter to fix the Boot Configuration Data associated with your Windows installation:
    bootrec /fixboot

    Note: If you get the ‘Access is denied’ error while inputting one of the 2 commands above, follow these instructions to fix the bootrec access problem. 

  9. Next, type the following command and press Enter to scan all your disks for the Windows installation media:
    bootrec /scanos

    Note: This operation might take some time depending on the size of your partitions. Don’t close this window until the operation is complete.

  10. If the operation is completed successfully, type the following command to effectively rebuild the BCD configuration data:
    bootrec /rebuildbcd
  11. When asked to confirm, type Y and press Enter to confirm and start the operation.
    Confirm the operation of building the BCD file system
  12. Finally, type ‘exit’ and press enter to effectively leave the elevated CMD prompt and allow your Windows to boot normally.

In case the end result is the same (the boot attempt ends with the same No Such Partition error), move down to the next method below.

Method 3: Using the Registry Backup to Restore the last good Configuration

If none of the methods above have worked for you, you might be able to fix the current configuration with the last known good backup that should allow you to dual boot without issues.

Doing this will require you to use the Advanced Options menu to open an elevated Command Prompt and run a series of commands that will allow you to boot using the last known good configuration.

This method was reportedly used successfully by a lot of users dealing with the No Such Partition -Grub Rescue error.

In order to use the Registry Backup to restore the last known good configuration, follow the instructions below:

  1. Insert a compatible Windows installation media and boot from it by pressing any key when prompted to do so.
    Booting from the installation media

    Note: If you don’t have a compatible installation media or your system doesn’t boot from it, follow steps 1 to 4 from Method 2.

  2. Once you manage to successfully boot from the installation media, click on Repair your computer from the bottom-left corner of the screen.
    Repairing your computer
  3. Once you’re finally inside the Advanced Recovery menu, click on Troubleshoot, then click on Command Prompt from the list of available Options.
    Accessing the Command Prompt via the Recovery menu
  4. Once you are inside the elevated Command prompt, type ‘C:‘ and press enter to access the partition where you installed Windows. If you installed Windows on a different partition, replace the letter accordingly.
  5. Next, type ‘dir‘ and press Enter to access the root location of your OS drive.
    Note: It’s recommended to back up the current registry before going forward. To do this, input the following command and press Enter after each command:
    cd windowssystem32config
    MD backup
    copy *.* backup

    Backing up the Registry
  6. Next, type the following commands and press Enter to access the last known good configuration and modify the default behavior to boot from it:
    CD regback
    copy *.* ..
  7. When prompted by the prompt, press A and hit Enter once again.
  8. Finally, type exit and press Enter to exit and boot normally. This should take you to the main GRUP menu where you should be able to dual boot as you see fit.

I am using Windows 10 and Ubuntu in my laptop. My windows was getting updated and during that process it was restarting several times. While restarting 2nd/3 rd time grub ran into problem. I am getting error:
no such partition and then message: "entering grub rescue mode" and then grub rescue prompt opens.

I have tried listing all the drives like

ls (hd0,msdos1)
ls (hd0,msdos2)
ls (hd0,msdos3) 
ls (hd0,msdos4)

All 4 commands gives error: unknown filesystem. Then i tried using some tricks on internet
Like

1) Set
2) Set boot=(hd0,msdos6)
3) set prefix=(hd0,msdos6)bootgrub
4) insmod normal

This again gives error: no such partition

Then i created bootable pendrive for windows 10. When i select from boot menu usb storage devices then
I get message: press enter to boot os using USB .. when i press enter Error occurs saying

    Windows failed to start. 
    "Some guidelines here..."
        
    Status: 0xc0000f

Boot configurations are missing or may contain error.

I am constantly trying from yesterday. So if anyone have any idea can you please help me with this??
