You're missing the not uncommon case of "UEFI firmware with CSM forcibly enabled and no UEFI boot option" which was much of the market between 2009 and 2011. These implementations will frequently understand GPT well enough to decide that a disk isn't BIOS bootable, but won't let you perform a UEFI boot instead. -- Matthew Garrett | mjg59@xxxxxxxxxxxxx -- devel mailing list devel@xxxxxxxxxxxxxxxxxxxxxxx https://admin.fedoraproject.org/mailman/listinfo/devel Fedora Code of Conduct: http://fedoraproject.org/code-of-conduct
