Hi Jeff, yes, I tried this, and if I set a password for the hdd in BIOS, I can disable UEFI. However, the nvme-drive needs UEFI activated, thus my livesystems won't boot. I tried to overwrite the actual firmware, but as it was the newest one, the installer inhibits to overwrite the existing BIOS. Hope this make things clearer Best Hans
