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:

  1. Boot into Windows 10 DVD / USB and go to repair option
  2. Open Command prompt
  3. Use command: 
    bcdboot C:\Windows
  4. 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
