I tried changing to mbr2gpt

So last night I tried to go to mbr2gpt to use secure boot, I had no issues doing so and my computer was running perfectly fine. Until today I just tried to boot it up and unfortunately it wont boot past a black screen that says “Loading operating system”, now I have the Gigabyte GA-P55A-UD4P motherboard and I’m not sure if that’s the issue or what it is my computer just wont boot past the “Loading operating system” I don’t know much about computers so that might’ve been my first mistake trying to mess around with settings I know nothing about lol

    If your motherboard or BIOS settings aren’t configured to boot with UEFI, then Windows won’t load, showing that “Loading operating system” stuck or just a black screen.
