    Can't boot Windows 10, UEFI bootloader GPT partitioned system drive. Tried bootrec (Total identified Windows installations: 0)

    Hi, I am trying to help a friend repair her son's computer so I don't have a lot of context as to what happened prior to this issue, but I will try to be as comprehensive as I can in describing what steps I've taken so far.

    Initial Observations

    This is a Windows 10 PC, with a 2 TB disk. It is UEFI enabled and GPT partitioned. Computer boots up and immediately begins
    Preparing Automatic Repair. The computer reboots without going to the Choose an option menu and boot-loops through this sequence.

    Method 1

    • F11 to force boot options menu
    • Boot into local disk recovery partition
    • Launch cmd prompt in recovery environment
    • Commands issued:
      • bootrec /fixboot
        • The operation completed successfully.
      • bootrec /rebuildbcd
        • OUTPUT: Total identified Windows installations: 0

    Method 2

    • Created recovery drive on my own Windows 10 PC
    • Booted problem PC with the recovery drive
    • Attempted startup repair multiple times (no luck)
    • Attempted bootrec commands again (no luck)

    Method 3

    I attempted the solution suggested
    HERE
    . At step 5, I got this error:

    Path not found - C:\boot

    So I changed the operations for steps 5 & 6 to target the system recovery volume on the disk:

  4. Bootrec rebuildcd is identifying old windows installation

    Total identified Windows installations: 0

    Hello,

    These steps actually worked for me. Then I made the mistake to go back and type in the command prompt bootrec / fixmbr

    Bootrec / fixboot

    And finally bootrec / scanos and find the same error message I had before. Total identified Windows installations:0

    After this I tried the same steps that worked as you mention above, but I encounter while trying to rename the bcd as a duplicate file.name exists. Is there another name I could use?
