Hello @
Bios - I
Yes Big Sur works correctly.
I put the pen drive (Monterey installation disk on the USB) and it boots, I choose the HD that will be done the clean installation.
It loads to the end on this HD, on the first boot, it tries to continue the installation and the Apple appears, then the boot after 2 seconds, I've already cleaned NVram I tried several times to start and always boot at the apple's entrance (2 seconds).
Get to clean the bios, trying several settings, but always boot.
Yes, both the boot disk from the pen drive and the SSD have the same EFI.
I'm going to activate Picker and post the screen.
