Sacha,

Let's try deleting the erroneous boot entries which are pointing to a non-existent device.

The statutory warning applies! Before modifying the boot configuration, please backup your system image (the OS and boot partitions) to an external hard drive using Macrium Reflect Free edition.

From Admin Command Prompt, run:

  • bcdedit /export c:\boot_config_backup.bcd
  • bcdedit /delete {9649d88d-4b28-11ed-8001-6d7368757261}
  • bcdedit /delete {4069d4e4-2920-11ed-be4c-a85e45d0a878}

Then, run these commands and post the output here:

  • bcdedit /enum All
  • bcdedit /enum All -v

    Ok, how do I do that?

    Oh, I forgot

    "But without a system image backup, the procedure shouldn't be attempted."

    You mean like a clone right? I tried to make an image backup with that app you suggested, but it only made some xml file of a few gigabytes, so maybe I'm missing something

    Ok I tried to do that with AOMEi partition assistant and it would not let me, it needed to reboot in a Windows PE environment but due to the error we're dealing with it could not.

    About backing up Windows and boot partitions, pls see this page and this. It creates one or more images with file extension .mrimg.

    To run Chkdsk on the EFI boot partition, run:

    • Diskpart
    • sel vol 4
    • assign letter=y:
    • exit

    Then, run:

    • robocopy Y:\EFI E:\Boot_files /MIR
    • chkdsk y: /r
