Gotta remember that. O_O It is a relatively simple bridge to cross. Use gdisk to partition the drive, which if you've used fdisk before you'll find it quite similar. If you prefer it fdisk will work too, but make sure first you create a GUID Partition Table (GPT) and not an MBR table. You can also use sgdisk to create a 1GB EFI System Partition (type 0xEF00) in a single command, as your first partition in an empty disk; e.g.: sgdisk -n 1:2048:2068470 -t 1:ef00 -c 1:"ESP-Boot" /dev/sda Then format it: mkfs.fat -v -F 32 -n ESP /dev/sda1 mount it as mnt/gentoo/boot and 'mkdir /mnt/gentoo/boot/EFI', to store at a later stage your kernel/initrd in it, before you continue with the rest of your installation. That's all there is to it. > If you usually use a separate partition for /boot, all you need to do > differently is set its partition type to EF00 and format it with FAT > instead of ext2. > > Oh, and if you use GPT, you no longer need the MBR compatibility > partition, or whatever its called.

Man pages of partitioning tools refer to it as "Protective MBR", although I've seen it mentioned in the interwebs as "protective GPT", which I think is more accurate. It uses the first sector (LBA 0) to store an MBR table showing the whole disk, or 2TB if smaller, as an MBR partition. This is the first partition on the disk, typically 1 MiB in size. It is meant to stop 20 year old partitioning tools from messing up a GPT partitioning scheme because they can't see it. Arguably nobody uses Windows 98 these days, so it should be safe to not have a protective MBR on your GPT disks. --nextPart4303301.ejJDZkT8p0 Content-Type: application/pgp-signature; name="signature.asc" Content-Description: This is a digitally signed message part.
