I have been running a Win 10 system in non-Secure boot configuration for a while because of dual booting with Win 7. This system has, however, in the past run fine with secure boot which meant turning on Secure Boot and Disabling the CSM.
Yesterday I was going to set it back to Secure Boot and got the message in the attachment. When I changed it anyway the system booted to an Orange screen and stopped. Changing it back, of course, corrected the situation.
What might have changed to cause my M.2 PCIe drive to no longer have an approved UEFI driver? Bios updates have occurred as well as Windows Updates, so one of those must be responsible. I have been unable to find a updated UEFI driver for the Samsung SM 951 M.2 drive which is not NVMe.
What might have happened if I was running Secure Boot when such a change was made? Could it be happening to others?
I have ordered a new M.2 drive which is NVMe capable to see if that helps. For now I will just leave the CSM enabled although technically that is not Secure Boot..
Any observations/info?
ASUS X99 Motherboard with latest Bios update.
