my C64x does not show BIOS preferencies anymore

[technotron]

Hello,

after changing the BIOS CSM settings in an attempt to boot from an external hard drive I ended with my C64x not showing the boot menu anymore and I cannot access the BIOS.

Can someone help me? I am in panic.

The commodoreOS Vision 2.0 in a pen drive doesn't start while an ubuntu 22.04 pen drive starts.
I hope this might give some clues.

ok, luckily I've found the solution to this problem.

I just pressed and hold the F2 key during the booting process and I was able to gain access to the BIOS setting again.
