Method 3: Verify Whether BIOS Supports the Windows Version

If your computer isn’t starting up properly, you may need to update your BIOS. However, before you do that, you should verify whether your BIOS supports the Windows version that you’re trying to fix. If it doesn’t, you won’t be able to fix the problem using the instructions on this page.

To check if your BIOS supports the Windows version that you’re trying to fix, go to your computer manufacturer’s website and look for a downloads or support section. Once you’ve found it, look for a BIOS update for your specific model of computer. Once you’ve downloaded it, double-click on the file to start the installation process.

During the installation process, you’ll be asked if you want to update your BIOS. If you do, make sure that you have a backup of your current BIOS in case something goes wrong.

Alternatively, try to install a different version of Windows on your computer, and in the event that you encounter the error message “This system cannot boot,” Windows is unable to start the installation.

Method 4: Deleting All Computer Partitions

Some affected users have said that they were eventually able to go through with the installation and finish the process without the “Windows could not prepare the computer to boot into the next stage of installation” error only after they deleted all partitions and started the OS installation process from scratch.

If your computer won’t boot, it’s likely because one or more of its partitions isn’t properly formatted. This can be fixed by deleting all the partitions on your computer, but doing so could not prepare the computer to boot. In most cases, simply reformatting the hard drive and reinstalling Windows will fix the problem.

Naturally, this can present a major problem if you’ve been merely interested in updating an existing Windows installation. However, if you have come this far with no success, you can select another method. In the event you don’t want anything to go wrong, cloning your system image first will make a Windows repair disk so you can get back to the beginning of the process.

For doing this method, you need to follow these instructions:

• Right-click on the Windows icon and click on “Device Management” from the given option list. 
• Now the hard disk partitions of the computer will open in front of you. Delete all partitions except the first “C” partition. Make sure you copy your valuable data from the computer to a USB or external hard disk before deleting it.

After you complete the actions, the partition and its contents will no longer be available on the drive, freeing up space to expand another partition or format the disk with a new format.

Method 5: Update the BIOS

BIOS updates can be important in keeping your computer running smoothly. In some cases, a BIOS update may be required to fix an issue that prevents your computer from booting up properly. If you are experiencing problems with Windows 10 not preparing your computer to boot, you may need to update your BIOS.

To update your BIOS, you will need to download the latest version from your motherboard manufacturer’s website. Once you have downloaded the file, double-click it to begin the installation process. The installer will guide you through the process of updating your BIOS.

Be sure to follow the instructions carefully, and backup your data before beginning the update process. If something goes wrong during the update, your computer may not be able to start up properly.

Updating your BIOS is a risky procedure, so make sure you are aware of the risks involved before proceeding.

Why Is Windows Unable to Boot Computer Into Next Phase of Installation?

How to Fix This Installation Error?

Now that we’ve briefly understood the causes that lead to this error, we can move on to its fixes. This guide covers all the working methods, that include steps ranging from a simple verification check to more technical fixes. By the end of this guide, we are pretty sure that your installation will be completed successfully. 

Ensure the BIOS Supports Your Windows Version

Firstly, make sure that your motherboard BIOS supports the Windows version you plan to install. If you’re deciding to upgrade to Windows 11, the Legacy BIOS mode is not supported. And somehow, if you have already installed Windows 11 with the Legacy BIOS, you cannot further update your OS anymore. 

So, it’s advisable to first ensure that the BIOS and your OS are compatible with each other. Surf the web and visit your manufacturer’s website to determine if they work together or not. 

Ensure That the Windows Installation Media Is Configured Properly

A pretty common reason that affects the installation process is improperly configured installation media. A bad Windows setup file directly lead to various installation problems, including the one you’re facing as well. 

So, if you’re unsure about the credibility of your media file, you can simply recreate it with the right steps. You can use either Rufus or the Media Creation Tool to create a bootable USB. Luckily, we do have a dedicated guide that aims to guide you with a step-to-step process on how you can create a Windows installation media the right way. 

Note that if you plan to use a bootable USB drive, do so via the USB 2.0 port on your computer. However, if the issue still persists, follow all the steps listed below until one of them fixes your problem. 

Disconnect the Non-Essential Peripherals

It’s important to disconnect any non-essential peripherals that might be connected to your device during the installation process. Either because of a bug or glitch, some BIOS versions have been known to act in an unwanted manner when too many unnecessary devices are connected during the installation process. 

Disconnecting non-essential peripherals such as your headphones, speakers, USBs, and maybe even your extra hard disks can prevent any conflicts that might occur during setup. If you have not done so, remove unnecessary devices, restart your computer and try installing the OS once again. 

Update BIOS

An outdated BIOS is known to give rise to certain compatibility issues between the operating system and the hardware devices. Also, there might currently be various security requirements that can only be resolved by updating the BIOS. So, updating BIOS can also fix the bugs present in the previous build and incorporate new patches to make the system function better. 

Hence, before you begin the installation process, visit your motherboard manufacturer’s website and download the BIOS file compatible with your system. We also have a guide dedicated to how you can update your BIOS safely.  

Keep in mind that the BIOS resets back to default after a fresh update. So, you will need to reconfigure all your custom settings once this is done. 

Run CHKDSK

The Check Disk (CHKDSK) tool in Windows OS helps you determine hard disk errors and also tries to troubleshoot them. The main goal of CHKDSK is to ensure that your computer’s disk drives are healthy and functional. It also checks for any file corruption due to bad sectors on the hard drive and aims to repair them as well. 

The CHKDSK can be run using a couple of different methods, but here, we will be doing so via the Windows Recovery Environment. For this, 

1. First, boot into your computer using the installation media. 
2. As soon as the computer beings to start up, repeatedly press the F8 key to access the safe mode options.
3. Click F10 to see more options. 
4. Then, click either 1 or F1 to launch the Windows Recovery Environment.
5. Here, click on Troubleshoot. 
6. Then, select Advanced Options.
7. Go to the Command Prompt. 
8. Now firstly, you’ll have to enter the name of the drive on which the OS is installed.
   For most users, it’s in the C drive. So in this case, type and enter c:.
9. Then, type the following commands and hit enter after each one:
   chkdsk /f
   
   This command scans for and aims to repair any errors within the disk’s file system.
   After the process is complete, type,
   chkdsk /r
   This command scans for and repairs bad sectors within your disk drive. 
10. Finally, type and enter exit to exit the command prompt.

Enable UEFI on BIOS

Although the UEFI firmware has been around for almost a decade, this step is a must if you’re planning to upgrade your OS to Windows 11. Also, if Windows 11 was previously installed on your computer in the Legacy BIOS mode, it’s necessary to change to UEFI. This will allow your system to update your operating system and also continue your failed installation. 

The UEFI has plenty of advantages over the older Legacy BIOS and can hence be enabled with these steps:

1. Restart your computer.
2. Enter the BIOS during system startup by tapping the key appropriate to your motherboard.
   
3. Once you access the BIOS, find and navigate to the Boot menu. 
4. Click on the option resembling Boot Mode. 
5. Select UEFI. 
   
6. Finally, press F10 to save your changes and exit the BIOS. 

Disable CSM and Secure Boot 

Although CSM and Secure Boot are useful additions to the UEFI firmware, we have dug up various forums to find out that they can be pretty troublesome during the installation process. 

The CSM feature allows the UEFI firmware to access certain features of the Legacy firmware. Whereas, the Secure Boot ensures that your computer only boots up using the Original Equipment Manufacturer’s software. So, for now, disable CSM and Secure Boot, and then try to continue the installation. 

Once the installation process is complete, you can then re-enable these features at a later date. The steps to disable CSM and Secure boot are as follows:

1. Restart the computer. 
2. Enter your system BIOS. 
3. Find and navigate to the Boot tab.
4. Click on CSM Support and select Disable.
   
5. Now, set Secure Boot as Disabled. 
6. Finally, press F10 to save your changes and exit the BIOS. 

Re-Configure Partition

If unfortunately, your OS setup is getting stalled due to corrupted system files, you have to delete the particular volume on which Windows is installed. This will clear all the data within the volume, including the partition details.

It’s also advisable to set the appropriate drive partition style before you begin the installation procedure. That is, if you’re using a UEFI BIOS, you have to set a GPT drive partition style. And, for legacy BIOS, you should set the MBR drive partition style. 

So, for this,

1. Boot into your computer using the installation media. 
2. When you’re on the setup window, press Shift + F10 to enter the Command Prompt. 
3. Type the following commands and hit enter after each one:
   • diskpart
   • list disk
   • select disk n. Here, replace n with the number associated with your disk.
   • list volume
   • select volume n. Replace n with the volume where your OS is installed.
   • delete volume
   • convert gpt (only if the partition style is MBR. Also, using this command will wipe your entire disk)
   • create partition primary size=100. This command creates a system volume.
   • create partition primary. This command creates a boot volume.
   • list partition
   • select partition n. Replace n with the number assigned to your system partition.
   • active
   • list volume
   • select volume n. Here, replace n with the volume where you want to install the OS.
   • assign letter=C
   • format quick
4. Once this process is complete, type exit to exit the command prompt. 

Enter the setup window and continue the setup on c: drive. You’ll now notice that the installation shall proceed smoothly.

Как я понял это баг, так как установщик встаёт из-за того что активный диск не тот, на который устанавливается система!

Куда о нём можно сообщить?

На форуме как я вижу тема никого не заинтересовала!

Что Вы понимаете под активным диском? Висту я не раз ставил на второй диск, и каких-либо проблем с этим не возникало.

Вы поменяли порядок загрузки с дисков в биосе? Некоторые матплаты выполняют эту процедуру не совсем аккуратно.

Я наверное не правильно выразился, вообщем смотрите: у меня есть 1 физический жёсткий диск, который разбит на 3 логических (на 1 WindowsXP и Windows 2003 server, на 2 Windows Vista и на 3 различные файлы) по умолчанию активным является 1 раздел (set active), тоесть сначала проверяется его загрузочный сектор, Vista ставится на 2 раздел, но инсталятор не может переключить активный раздел!

Опять что-то не так объяснил?

Слышал, что за обнаружение багов дают бесплатно финальную версию, куда запрос отправлять? Кроме этого нашёл ещё один. И пожалуйста, не игнорируйте тему, если что не так, поправте меня.

Есть подозрение. Разделы на диске, случаем, не с помощью PM создавали?

Чтобы за сообщение об ошибке получить экземпляр висты, надо было, во-первых, предварительно попасть в число бета-тестеров, во вторых, отправить сообщение до 8 ноября.

Программа установки не меняет активный раздел. Какой был активным до установки, тот и после останется.

Вообще-то есть некоторые проблемы и с RTM

» Кажется, Microsoft и в этот раз напутала: volume-подписчикам были переданы неправильные релизы Windows Vista Business и Enterprise Edition.

C релизом, который состоялся ранее в этом месяце, появились проблемы с установочным DVD, а также с установленными версиями Vista.

Windows could not prepare the computer to boot into the next phase of installation

Вопрос

On my Laptop Dell 7559 Skylake I’ve plugged an SSD EVO 850 M2 500GB where I’ve succesfully transferred the OS by using the Samsung utility. Then I’ve made a second partition on the same drive, by using Paragon Partition Manager Free.

Now I’m trying to install Windows 7 pro 64 bit (Microsoft ISO, edited by following instructions by Dell on http://www.dell.com/support/article/us/en/04/SLN300564) on this new partition, but the installation fails with the message

«Windows could not prepare the computer to boot into the next phase of installation».

Ответы

Based on your situation, are you trying to setup dual boot Windows 10 and Windows 7?

I found that you cloned this Windows 10 system using the Samsung utility, considering that it is a third party utility, cloning Windows system is not in our support scope, Microsoft does not provide support for cloning system.

But here is something we could do it for you, it seems that there is Windows 10 already installed on your system, to setup dual boot, we need install older versions of Windows before Windows 10. Install Windows 10 before older versions of Windows will broke BCD store and cause unbootable issue.
Please check the following link about how to dual boot Windows 10 and older versions of Windows.
