I have updated my Rog Rampage VI extreme encore to bios 1101 which was suppose to make it compatible with windows 11. Suprise it made the settings change unbootable. I found that while the boot ssd was visible in the simple bios settings it no longer showed in advanced boot until I changed back from UEFI to other in the system software. Then I could reset the default boot to the right ssd and load windows 10 again. I found that if I activated UEFI or turned off CSM the option to select the boot drive disappeared and the no boot drive found warning took me back to the bios setup. In the simple mode the drives still showed in the drive list but nothing showed in the bootable drive list. I have a wide variety of drives-M.2 ssds-ssds-2-15tb hard drives-USB connected drives of all types etc. The boot M.2 ssd is on an ASUS M.2 4 ssd card in a PCIe slot. ASUS help was no help as I had already done the trouble-shooting they suggested. Any ideas? I did check that the new bios set up the PTT value to active and started the tpm security hardware. When I ran the microsoft 11 compatibility test with CSM and Other selected it just said I could not provide a safe boot (which is turned on).
