Does Fedora 16 boot on UEFI computers that do not have the legacy 16-bit BIOS? If not, you will need to install Bootcamp under Mac OS X with the Boot Camp Assistant. It is in /Applications/Utilities under Mac OS X. Bootcamp installs a 16-bit BIOS emulation as a 32-bit UEFI application. rEFIt, among other things, creates a Master Boot Record with a partition table that can be synched with the UEFI GUID Partition Table. Linux knows all about GUID Partition Tables. I do not know whether or not GRUB does. I think your problem is that GRUB wants the 16-bit BIOS. There is a 32-bit UEFI boot loader that may work for you, that would not require either Bootcamp or rEFIt. I looked into it a couple years ago, but it was not then considered mature enough for production use. Possibly it is now. I don't recall what it is called, though. -- Don Quixote de la Mancha Dulcinea Technologies Corporation Software of Elegance and Beauty http://www.dulcineatech.com quixote@xxxxxxxxxxxxxxxx -- users mailing list users@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe or change subscription options: https://admin.fedoraproject.org/mailman/listinfo/users Guidelines: http://fedoraproject.org/wiki/Mailing_list_guidelines
