Actually, if I've understood what I've read over the past two weeks, that's not correct. You need a dedicated partition formatted in FAT32, marked ef00 partition-type with the "boot" flag enabled on it. Mounting that partition on /boot/efi (or somewhere else, depends on the distro) is a LInux thing. > I also plan to migrate to UEFI boot in Feb. :) Best of luck. I got the last two components of my new system today. It's my Christmas present to me! No one gives me toys anymore. So, I buy them myself. ;-) B
