    Upgrading to windows 11

    I have a few questions about windows 11...

    1. How many GB it is? when my pc suggested the upgrade yesterday, it said it's about 4GB just want to be sure.
    2. I'm using a windows 10 pro so if I upgrade, will it upgrade to a windows 11 pro?

    Windows 11 upgrade failed.

    Thanks.

    The BCD or the EFI boot partition's file system is corrupt. Rebuilding the EFI boot partition fixes this issue.

    Please go through these links for more information:

    If you need step-by-step assistance in this regard, boot into WinRE Command Prompt.

    Then run:

    • mountvol y: /s
    • bcdedit
    • diskpart
    • list vol
    For each command, photograph the screen and upload it to OneDrive.
