FIX: Windows could not update the computer's boot configuration. (Solved)

Last updated on October 19th, 2020

The Windows 10 setup error "Windows could not update the computer's boot configuration. Installation cannot proceed." commonly appears in computers that supports UEFI and have the Secure Boot enabled. To resolve this problem, you have two options: to disable the 'secure boot' and to start the installation from a Legacy USB boot device or to create the boot configuration files manually.

FIX Windows could not update the computer's boot configuration.

 

This tutorial contains two methods to resolve the Windows 10 installation error "Windows could not update the computer's boot configuration. Installation cannot proceed."

How to FIX: Windows could not update Boot configuration in Windows 10 Setup.

Method 1. Disable Secure Boot in BIOS & Boot from Legacy USB.
Method 2. Create the Boot Configuration Files Manually.

 

Method 1. Disable Secure Boot in BIOS & Boot from Legacy USB.

1. Enter BIOS (CMOS) Setup settings.
2. Enable the Legacy support.
3. Change the Boot Mode from UEFI to Legacy (CSM).
4. Then Disable the Secure Boot in Security options.
5. Set as First boot device the Legacy Windows USB drive.
6. Save and exit from BIOS Setup.
7. Boot from the Legacy USB drive and continue to install Windows 10. *

* Note: If you cannot boot from the USB, then recreate the USB drive for a Legacy System (MBR Partition scheme). To do that:

a. If you haven't done so already, download Windows to an ISO file by using the Media Creation Tool.
b. Then, download and run the Rufus USB Creation Utility.

c. Plug an Empty USB Drive on your PC. (Keep in mind that all files on the USB will be deleted, during the creation process).

d. In Rufus utility, do the following:

1. Choose the empty USB stick that you plugged in your computer.
2. Click Select and choose the "Windows.iso" image file.
3. At Partition scheme, choose: MBR
4. At Target system, choose: BIOS (or UEFI-CSM)
5. At Volume label, you can enter any volume name for the USB disk (e.g. "Win10")
6. At File system, choose: NTFS.
7. At Cluster size, leave the default size: 4096 bytes.
8. Finally click Start.

Method 2. Create the Boot Configuration Files Manually.

1. When you see the "Windows could not update the computer's boot configuration. Installation cannot proceed" message, press the SHIFT + F10 keys to launch the command prompt.

2. In command prompt type the following command to list all the drives on your system:

  • wmic logicaldisk get name

wmic logicaldisk get name

 

3. Now, by using the "DIR <Drive_Letter>" command, examine the contents of all listed drives (except the drive X:), to find out which drive contains the "Windows" folder. (e.g. "dir C:") *

  • dir C:

* Note: If the Windows directory is displayed then continue to the next step. otherwise continue by typing the next alphabet letter until you found which drive contains the Windows folder (e.g. dir d: , dir e:. dir f:, etc.).

(In this example the Windows folder is located at drive C: )

4. Then open the DISKPART utility by typing the following command and press Enter:

  • diskpart

5. At DISKPART prompt type:

  • list disk

list disk command

 

6. Now type the following command and then press Enter:

  • select disk X 

* Note: Where "X"= the number of the disk where you install the Operating System. (e.g. the disk 0 in this example).

select disk command

 

7. Then type the following command and press Enter.

  • list partition

8. Find out which Partition is labeled as System.

(In this screenshot the Partition 4 is labeled as System)

list partition command

9. Select the System partition by typing:

  • select partition X (Where "X "is the number of the partition labeled as System. e.g. "4").

select partition command

10. Assign a drive letter (e.g. the letter "S") to the System partition by typing the following command and press Enter: *

  • assign letter=S:

* Note: If the drive letter "S" is already used, then give the next drive letter in alphabet.

assign letter command

 

11. Type exit and press Enter to close DISKPART tool.

12. Then give the following commands in order (press Enter after typing each one of them).

    1. cd /d S:\EFI\Microsoft\Boot\
    2. ren BCD BCD.bak
    3. bcdboot C:\Windows /l en-us /s S: /f UEFI

Notes:

1. Change the letter "S" if you have assigned a different drive letter to the System partition.

2. If Windows is located on a different drive then use that drive letter instead of "C".

3. The "/l en-us" part of the above command sets the Windows language to English. If you want to set a different language, then replace the "en-us" with the appropriate language code (e.g. "fr-FR" for France).

 

13. When the command is executed, press the Power button for 5-6 seconds to fully shutdown the PC.
14. Unplug the USB media.
15. Power ON the PC to finish the Windows 10 installation.
