Gigabyte Z390 Aorus Pro

CPU I5-9600k 32G Ram Geforce 1050 TI, HDD is formatted GPT. Problem: When I try to install Win11, With PTT on, and I disable CSM so I can turn on Secure Boot, as secure boot requires CSM to be disabled and I reboot the computer will not boot. In order to boot the computer, the bios has to be reset which enables CSM. To me this is a bios software issue. I am hoping someone has found a fix for the problem.

It sounds to me as though your boot volume is in MBR format rather than GPT. GPT format is required to use UEFI BIOS.

See this article on how to do the conversion.
