    Finally something worked! I’ve been looking all over the internet on how to fix my unsupported secure boot state because it keeps crashing my games. Btw, I’m using Asus Prime z790 mother board with windows 11 OS.
    Thank you so much!

      he said that we gotta make sure that theres no logical partition so it wouldnt interrupt the conversion since a logical partition is a another destination of storage in one drive i used chatgpt for help and i can do this without any problems or worries only worry is if my data might get deleted (you prob gave up on this or took a risk)
