I did some googling about this a while ago because a friend wanted to single-boot Ubuntu on her Mac Mini. She got cold feet and stuck to her dual-boot with rEFIt so the following is theoretical and from memory. (1) You have to keep sda as a gpt disk. ***start*** # parted (parted) print [if "partition table" is not "gpt] (parted) mktable gpt ***end*** (2) You have to move "/boot" to "/efi/boot" and it has to include a "boot.efi" (unsure of the exact name) grub binary/stage loader. Take a look at the structure of the Fedora 12 Live CD. (If you are booted from it, the "ro" not the "rw" mount.) -- fedora-list mailing list fedora-list@xxxxxxxxxx To unsubscribe: https://www.redhat.com/mailman/listinfo/fedora-list Guidelines: http://fedoraproject.org/wiki/Communicate/MailingListGuidelines
