The Fedora 37 development team is considering dropping support for non-UEFI BIOS. Linuxiac reports: The Unified Extensible Firmware Interface, or UEFI, is a modern method of handling the boot process. UEFI is similar to Legacy; however, the boot data is stored in a .efi file rather than the firmware. In the case of Fedora, while the change may take some time, the new Fedora x86_64 installations will no longer work on non-UEFI platforms. On x86_64 architectures, Fedora 37 will mark legacy BIOS installation as deprecated in favor of UEFI. While systems already using Legacy BIOS to boot will continue to be supported, new Legacy BIOS installations on these architectures will be impossible.
