Question Z790 Aorus Elite AX boots to bios every time

Hello all,

Installed the motherboard, new ram, M2's and 12th gen I9. If I reboot the warm pc, it gives me the normal menu option of dropping into bios for a few seconds before booting the OS. If the machine is powered off, the boot process drops into bios and waits. I can hit save and exit - boot continues normally.

Windows 10 was installed on the first M2. Linux was installed in the second M2 and the Linux install controls the boot via grub menu. Any idea what I've done wrong or potential fixes would be really appreciated.
