I'm trying to convert my windows installation partition from MBR to GPT. I need to access advanced startup -> troubleshooting -> command prompt.

To get there I need to insert my password. I tried my admin PC user PIN and my Microsoft account password and both were refused/incorrect. Which password should I use here?

Im following the steps here: https://www.windowscentral.com/how-convert-mbr-disk-gpt-move-bios-uefi-windows-10

    Dear Roberto

    you are at the Advanced Startup Command Prompt login screen, and it's asking for the password of the displayed user account.

    Straight Answer:

    You must enter the full account passwordnot your PIN, and not your Microsoft account password unless the account is actually linked to a Microsoft account.

    Best Regards,
