9.Again copy-paste and modify these commands in Command Prompt window one-by-one and hit Enter after each of them.

select disk your disk no
list vol

NOTE– Replace the “<your disk no.>” with the number of HDD drive on which the Windows is installed.

For this computer, it is “Disk 0“. So the command will be like this-

 select disk 0

]

 

New Select Disk 0

 

10. Again copy-paste this command in Command Prompt and then hit Enter to select the System reserved volume.

select vol <volume no.>

[NOTE– Replace the “<volume no.>” which is declared to have 100 MB storage. This partition contains the EFI (Extensible Firmware Interface) and usually formatted in FAT32 format.

Example- For us, it is ‘Volume 5 which is the FAT32 partition, and its size is limited to 100 MB. So the command will be –

select vol 5 

 

New Select Vol 5 Efi Part

 

11. Now, you have to assign a new drive letter to the partition. Copy-paste this command in Command Prompt window and hit Enter to do so.

assign letter=V:

Assign V New

 

Upon completion, you will see this message – ‘diskpart successfully assigned the drive letter’.

12. In order to exit the diskpart, type this command and press Enter.

  1. You have saved me… none of the other guides specified that I needed to load the fat32 volume and fix it with where windows is located.

  2. you are an angel. thank you so much!! u saved me from deleting all my files man. GOD BLESS YOU. TRUE TALENT RIGHT HERE.

  3. When you see this posts about how the technician charged X amount of money just to do a 30 second job, and then has to explain that it only took him 30 seconds to fix cause he spent the last decade studying to know how to do it in 30 sec…

    You Sir, are a legend 🙂

  4. You are a beautiful human being. Thank you. I spent several hours trying to repair my PC after messing up the boot manager in my BIOS and this worked perfectly. I’m signed in again and even have all of my files/apps still. Thank you so much!

  5. This fixed the issue for me, every other solution tries to run bootrec /fixboot, which runs into access denied errors, this one worked right away. Thanks for the awesome and straightforward guide

  6. Wahoo! I was confused at first by the 100MB suggestion for the EFI partition size. Mine was bigger (250MB), but it was FAT32 and listed as System, so I used that one and it worked.

  7. Hi Sambit,
    Disabling fastboot in Windows 10 20H2 corrupted my BCD and this fixed it. Really saved my bacon, so thank you very much for posting this.
    Cheers!

  8. I followed your direction and get this message:
    Your PC/Device needs to be repaired
    The operating system could not be loaded because the digital signature or one of the dependencies could not be verified.
    File \windows\system32\drivers\intelpep.sys
    error code: Oxc0000428
    I would appreciate any help…thanks

  9. I spent 3 days to find how to fix loop restart after the last update. And was ready to reinstall it, but your post saved me from it! Thanks a lot!!!

  10. doing a “cd /d V:” before “md \efi\microsoft\boot\” actually created such a directory on V: drive. But still “access denied” error on “bootrec /fixboot” aferwards…

    any ideas?

  11. Yeah, same as everyone else. Works fine until the second step of part 13 then it says, the system cannot find the path specified. Would love to know what to do about that.
    Thanks,

  12. I would so like to know how to do the Windows +I to fix the boot problem when the computer won’t boot. How do you get to it? I can’t find a screen on the Recovery system from which it will work.

  13. I get to step #14, but still see the same “Access is denied” message after entering “bootrec /fixboot”

    All this started after Windows had to reboot because of updates.

    Maybe it’s time to give Linux another try.

  14. In Step #13.
    When I try to type in cd /d V:\efi\microsoft\boot\
    I get “The system cannot find the path specified”
    And none of the remaining commands work. bootrec /fixboot still gives the “access is denied” error. Please help.
