So I have on my laptop (asus zephyrus g14) Manjaro (linux) and Windows 11 pro at the same time. Both are not encrypted. But I want to encrypt my Windows 11 pro using BitLocker. The TPM is available. When I start the BitLocker and click on "Turn on BitLocker", I get an error message saying "The volume for a file has been externally altered so that the opened file is no longer valid". I tried to clear the TPM but still have this error. I don't know what to do, I tried to google this issue but I found nothing! Please I need some help!

    Hi @Fedi Abichou

    This might be due to Windows boot manager being edited when installing linux. Couple of questions:

    What version of Linux you running?
    Did you install Linux through windows? E.g. like Ubuntu or via booting to the live USB/CD and installing from there.
