It's easy enough to check if your disk is GPT or MS-DOS: run 'parted /dev/XdX' (with the appropriate device, obviously) and type 'print'. There's a 'Partition Table:' line in the output, it tells you 'gpt' or 'msdos'. > The exact same message happens on F16 with GPT disks using the > customize installation type, if you forget to create a BIOS Boot > partition. > > I don't think GRUB2 devs mean for BIOS Boot to be required per se, but > I think it's a good enough idea for a distribution to require it, > because on GPT disks there's no obvious safe place for core.img to go, Indeed, grub2 is pretty much incidental here. It's the GPT disk label which causes anaconda to require a BIOS boot partition, not the use of grub2 as the bootloader. grub2's core image is somewhat larger than grub1's, but that's not _really_ either here nor there. Neither can reliably be expected to fit into the MBR space on a GPT-labelled disk. (grub2's sometimes doesn't fit even into the MBR+embedding space on an MS-DOS labelled partition, but that's a different question...) -- Adam Williamson Fedora QA Community Monkey IRC: adamw | Twitter: AdamW_Fedora | identi.ca: adamwfedora http://www.happyassassin.net -- devel mailing list devel@xxxxxxxxxxxxxxxxxxxxxxx https://admin.fedoraproject.org/mailman/listinfo/devel
