Adding Windows 10 BIOS UEFI option
If Windows 10 is installed using UEFI the Windows Boot Manager path on first GPT partition (EFI) is:
\EFI\Microsoft\Boot\bootmgfw.efi
This can be useful in case boot manager option is edited / deleted accidentally.
Restoring Windows 10 UEFI files
If the UEFI partition was formatted as part of another OS installation then the Windows 10 UEFI boot files can be restored via:
- Boot into Windows 10 DVD / USB and go to repair option
- Open Command prompt
- Use command:
- bcdboot C:\Windows
- If the partition itself is deleted then it can be re-created by using some combination of:
- diskpart
- list disk
- select disk <n>
- list partition
- create partition EFI size=260
- format quick fs=fat32
- list partition
- list volume
- After this we should use bcdboot C:\Windows to create Windows UEFI files in the EFI partition
Non UEFI Windows MBR restore
For non-UEFI systems have a look at Restore boot loader for Windows 7 or Vista after removing grub
