Fix UEFI Boot: Fix for Windows 7, 8, 8.1, 10

Fix UEFI Boot in Windows 7

The step-by-step instructions for fixing the UEFI/EFI boot on a Windows 7 system are very similar to those of Windows 8/8.1:

• Use bootrec
• Use diskpart
• Use Easy Recovery Essentials

Windows 7 can’t be installed if your computer’s UEFI/EFI mode is set as active and not in Legacy mode. Legacy mode allows your computer to boot Windows 7.

If your computer model is new and has UEFI/EFI installed, but you have Windows 7 installed, it’s most likely that you’re running UEFI/EFI as Legacy.

Follow the instructions from prerequisites below before you start.

Prerequisites

Before you start using the bootrec or the diskpart command to fix the bootloader of your Windows 7 system, first you must determine that UEFI/EFI loads with the Legacy mode active.

Follow these steps:

1. Restart your computer
2. Press the necessary key to open UEFI/EFI. The key depends on your PC manufacturer and PC model.Most common keys are: F2, F8, F12, Del. Esc is also an option.
3. Once inside the UEFI/EFI setup menu, search for Secure Boot.This is usually found at any of the following tabs: Boot, Authentication or Security.
4. Make sure Secure Boot is either Disabled or Off
5. Save these settings and exit the UEFI/EFI setup menu

Fix UEFI Boot in Windows 8, 8.1 or 10

To fix the UEFI bootloader on a Windows 8, Windows 8.1 or Windows 10 system, you can follow these options:

• Use diskpart to check if the UEFI partition has a drive letter assigned (if not, it must be assigned)
• Use Automatic Repair if diskpart doesn’t work
• Use Easy Recovery Essentials to automatically fix the UEFI bootloader

Fix #1: Use diskpart

If the UEFI partition on your computer doesn’t have a drive letter assigned, this may be the primary cause of your computer’s boot error.

A common is to use the diskpart utility (available on the Windows 8/8.1/10 recovery disc/USB) to make sure the UEFI partition has a letter assigned to it. If it doesn’t, you’ll assign it a letter.

The instructions you need to follow are:

1. Insert your original Windows 8/8.1/10 installation disc or installation USB
2. Boot from the disc or the USB
3. At the Install now screen, click Repair your computer or press R
   

   Windows 8 Repair Your Computer Menu

5. Click Advanced options
6. Click Command Prompt
7. When Command Prompt has finished loading, type:

   diskpart

8. Press Enter
9. The diskpart utility should now be loaded:

   DISKPART>

10. Type:

    sel disk 0

11. Press Enter
12. Wait for the confirmation message:

    Disk 0 is now the selected disk.

13. Type:

    list vol

14. Press Enter
15. diskpart will now show the full list of volumes available on your PC
    
16. Find the UEFI volume from the list. This usually has “BOOT” mentioned on the Label column, “System” on the Info column. The Fs column might FAT32 specified.For our example, in the next steps, our UEFI partition will be on Volume 2.
17. Type:

    sel vol 2

18. Press Enter
19. Type:

    assign letter=G:

    Where G: should be a unique drive letter. It can’t be already used, e.g. C:\, D:\
20. Press Enter
21. Wait for the confirmation message:

    DiskPart successfully assigned the drive letter or mount point.

22. Type:

    exit

23. Press Enter
24. Type:

    cd /d G:\EFI\Microsoft\Boot\

    Where G: is the drive letter you’ve assigned to your UEFI partition a few steps back. If the \EFI\Microsoft\Boot\ folder doesn’t exist (the error message will be “The system cannot find the path specified”), you can run the same command on alternative paths:

    cd /d G:\Boot\

    or

    cd /d G:\ESD\Windows\EFI\Microsoft\Boot\

    Remember to replace G: with the UEFI’s partition letter.
25. Type the bootrec command:

    bootrec /fixboot

    NOTE: on newer Windows 10 installs this command may return with an “Access Denied” error. On those versions the following command should be run:

    bcdboot C:\windows /s V: /f UEFI

26. Press Enter
27. For backup purposes, backup the BCD record of your computer like this:

    ren BCD BCD.bak

28. Recreate the BCD using the bcdboot command:

    Bcdboot C:\Windows /l en-us /s x: /f ALL

    Where C:\ is the letter of the drive where Windows 8, Windows 8.1 or Windows 10 is installed on. The /l en-us parameter is used for localization: US. You can use ln /en-gb for UK localization.
29. Press Enter
30. You can also run this command too:

    bootrec /rebuildbcd

31. Press Enter
32. Type exit in Command Prompt
33. Restart your computer
34. Your Windows 8/8.1/10 should now boot again
