 +In fact, that bootable Rescue Media also includes a “Fix Windows Boot Problems” option that I have used many times to repair boot issues. It’s adept at fixing boot errors that may pop up when editing or altering boot menus or boot configuration data. Access to this facility is depicted in the following screenshot (see how to take screenshots in Windows 10 or 11), and fully described in a useful Macrium Knowledge Base article (50168).

 +After the format you need to recreate the EFI directory structure with the command:
 +MD \EFI\Microsoft\Boot
 +Then change to the Boot directory with:
 +cd /d V:\EFI\Microsoft\Boot\
 +Then run:
 +bootrec /FixBoot

 +I struggled with this error too. I got it working by booting for an USB drive created with Rufus. A Windows DVD or another bootable medium would work too. Maybe the path changes in that case.
 +I verified if the BCD-Template file exists from the command prompt (which in my case didn't) by issuing:
 +dir %WINDIR%\System32\Config\BCD*
 +
 +Then I copied the BCD-template file from the Rufus disk (X:) by issuing:
 +xcopy X:\windows\System32\Config\BCD-Template %WINDIR%\System32\Config\BCD-Template

 +Step 9. Type assign letter=N: and press Enter. N: can be replaced by any drive letter that is not taken by any partition. Remember which drive letter you assign here for it is rather useful in the rest steps.
 +Step 10. Type exit and press Enter to leave diskpart.
 +Step 11. Now type N: (the drive lettered you just assigned) and hit Enter.
 +Step 12. Type format N: /FS:FAT32 and hit Enter.
 +Step 13. Type bcdboot C:\windows /s N: /f UEFI and hit Enter.
 +Now repeat the process of running the bootrec /fixboot command, bootrec access is denied Windows 10 should be solved now. But if fixboot access is denied occurs on an MBR disk, continue with Fix #2.
