I've spent two days trying to troubleshoot booting Unraid reliably. I'm using a Gigabyte z790 motherboard, I flashed to most recent bios, at first I couldn't boot unless I went into the bios first and then exited. I seem to have fixed this by disabling fast boot. I can't enable CSM support since I'm using igpu so I have to just choose the windows 10 option for secure boot, leave csm disabled and turn off secure boot. Now I was reliably booting, then I got into unraid, shut down the array to change a setting, couldn't access the webui, plugged in a monitor and I'm trying bzmodules checksum error, so I replaced all the bz files on the USB and the issue persists. Any recommendations?

Here's what finally worked for me, I rewrote the USB and copied over my config folder. I had to boot with the USB not plugged in and go to bios, finally I could disable secure boot, I then plugged the USB back in and enrolled the EFI image, make sure fast boot is off and now everything seems to work reliably
