Howdy!
I'm trying to turn secure boot on, but when I do, it seems the motherboard no longer recognizes my NVME drive as a boot drive. Am I doing something wrong, or have I just started wrong and cannot go back? So my boot options in bios are currently set to CSM / Legacy. If I change it to Ultra Fast UEFI it doesn't seem to see the NVME and boots into BIOS. Then I turned on Secure Boot in that new setup and it still boots to BIOS. It sees the NVME still with those settings turned on, but I'm not sure what's going on. HALP! :P The computer has been up and running for a year or two now.

That's the issue, right? MBR boot record/partition style?

Yes, MBR won't work without legacy mode enabled which needs to be disabled for CSM
to work. There are quite a few guides and videos on how to resolve the issue. Good luck |
