I have had similar and yeah once secure boot was taken care of it was fine. Unfortunately these bios things are heavily influneced by microsoft and then machines that come with windows have settings to make it hard to not boot the windows parition that was put in. To be clear this is not a linux thing and actually should be a reason you would want to run away from windows.
Awhile back this virtual avatar thing was popular. Maybe grok is a musk one.
