Can someone walk me through on how to accomplish this? ( step= -by-step commands ). Of course I have a rescuecd at my disposal. Thanks! Boot into the rescuecd Open your first disk with gdisk or parted: gdisk /dev/sda List partitions (p in gdisk and print in parted) Find a partition of the type EF00. That is your UEFI boot partition. Mark do= wn the number of that partition. The number most likely 1. If you didn't find EF00 partition search the next disk (sdb). Mount your boot partition (in my setup it is sda1): mkdir /uefipartition mount -t vfat /dev/sda1 /uefipartition nano /uefipartition/loader/entries/gentoo.conf Just edit and save and you are done. If you have everything setup as in the w= iki (http://wiki.gentoo.org/wiki/Gummiboot) this will work. Neil gave the sa= me instructions... This is just a bit more detailed. I like to always keep grub installed because it is like swiss army knife for= booting. You can always get a shell and find your lost kernel image. Even i= f it is still in /usr/src... So you kind of like never render your system to= an unbootable state. Nor would need to use rescue cd. And you can boot wind= ows, memtest, chainload etc! --=20 -Matti
