Windows 11 Help

[platinum0]

Hi, I am new here, but would appreciate any & all help -

Been trying to get my pc ready for Windows 11. Here is what I have done in order to get it prepared.

-Converted boot disk, mbr to gpt

-Enabled firmware tpm instead of discrete in BIOS

-Enabled windows uefi mode

-Attempted to follow a guide on an asus forum to disable launching csm to complete the secure boot procedure, but when I do this my pc just boots back to bios because it can't recognize any of my disks

I keep getting the warning on the pc health check that "this pc must support secure boot" everything else is good to go except this

Motherboard is an asus b450 plus II amd running bios version 3002

Thanks, Christian
