  1. Windows Boot Manager not found on Bitlocker encrypted System


    Two days ago my Laptop MSI GF63, with Windows 11 installed wouldn't boot, instead an old grub installation showed up indicating that no windows boot manager was found. Indeed, BIOS showed no windows boot manager, only grub. Problem is, that my Main partition is encrypted with Bitlocker no PIN or Password, only TPM chip.

    We suggest doing the following steps again to resolve the issue. To complete the procedure, make sure that you have the following information:

    • You must be able to provide administrative credentials.

    • Click Start, click Control Panel, click
      System and Security, and then click BitLocker Drive Encryption.
    • Click Suspend Protection for the operating system drive.
    • A message is displayed, informing you that your data will not be protected while BitLocker is suspended and asking if you want to suspend BitLocker Drive Encryption.
    • Click Yes to continue and suspend BitLocker on the drive.

    Let us know how it goes.
