Windows 10: Restoring Windows EFI files without wiping Linux EFI files

Hi,

I have recently re-installed Linux on my computer (I have a dual boot), and I have accidentally removed and recreated the EFI partition, so I can't boot into Windows.

I searchedsome tutorials, and I found this one which uses the `bcdboot` command to recreate to Windows EFI folder and files, but I'm afraid that it will wipe my Linux EFI files...

Will it wipe my Linux EFI files? What can I do to keep them?

Thanks!

:)

 

EFI partition delete issues and restoration

If I delete the EFI partition accidentally in Windows 10, how do I setup or manage or restore the EFI partition?

 

UNMOUNTABLE_BOOT_VOLUME after creating new EFI System Partition

Hello,

On my laptop (Acer Swift 3) I dual boot Windows 10 (stock Windows, not Acer's version) and Arch Linux, recently I ran out of space on my EFI System Partition (ESP) while trying to install a different Linux kernel, so I copied out all of the files on the
ESP, created a new, bigger one and copied all of the files back on. After removing and re-adding the boot options using the EFI shell, Linux booted fine (from rEFInd) but Windows no longer boots - every time it blue screens with UNMOUNTABLE_BOOT_VOLUME. I
have already tried:

• deleting /boot/EFI/Microsoft and /boot/EFI/Boot/bootx64.efi, then running `bcdboot /l en-gb /s s: /f UEFI` from a recovery disk - same problem
• running various `bootrec` commands, some said "Access Denied" (what???) and some claimed there are no valid Windows partitions even though one is mounted at C:
• Startup Repair - did not find any problems
• reinstalling Windows - the installer says it will reboot and continue afterwards, when it reboots it dumps me at the main installer menu, without having made any progress
• looking at EFI NVRAM variables - it is impossible to tell which of these actually affect the Windows boot manager
• `sfc /scannow` - it was a shot in the dark and lo and behold it did nothing

Any help getting Windows to boot again will be greatly appreciated.
