According to: http://wiki.gentoo.org/wiki/GRUB2#BIOS.2FMBR_or_BIOS.2FGPT BIOS/MBR or BIOS/GPT Installing in this mode is straight forward as it's just like the legacy GRUB with new GRUB2 additions. If you have a GPT partition table, you will need a small BIOS boot partition. 1 MiB may be enough but 2-4 MiB will definitely work. It will hold stage 2 of the bootloader and you don't need to format the partition with a filesystem - grub2-install will overwrite it anyway. You can mark a partition with the command line tool parted by typing (change 1 to the number of the partition you want to mark as a BIOS Boot partition!): I don't need to format sda1, grub2-install should take care of it. So what am I doing wrong? I've installed many Gentoo systems in the past (it was long time ago), everything went smooth but not this time. -- Joseph

[gentoo-user] installed Gentoo on SSD - no bootable device
I just installed gentoo on my new SSD (intel 480GB drive SSDSC2BF-480H501) I mostly was installing everything over ssh (easier) and using grub2 but upon rebooting I get: No bootable device - Insert boot disk and press any key I boot strap to my system: # swapon /dev/sda3 # mount -t ext4 /dev/sda4 /mnt/gentoo # mount /dev/sda2 /mnt/gentoo/boot # cd /mnt/gentoo # mount -t proc none /mnt/gentoo/proc # mount --rbind /dev /mnt/gentoo/dev # chroot /mnt/gentoo /bin/bash # env-update # source /etc/profile If boot strap and try to start ssh I and get a warning (and can not login) You attempting to run an openrc service on a system which openrc did not boot ...

When I installed grub2 I got no errors:
grub2-install /dev/sda
Installation finished. No error reported.
but looking at grub2 configuration, it is looking for kernel on sda4 (shouldn't
it be sda2?).

If I do: mkfs -t vfat -F 32 -n efi-boot /dev/sda1 mkfs.vfat: No such file or directory The easiest method would be to chroot into your installation. From there, you can format the EFI partition, then mount it. If you don't have mkfs.vfat in your chroot, I think the package that has it is dosfstools. So basically: 1. chroot into your install (makes sure /boot is mounted before chroot'ing in) 2. format the EFI partition, install dosfstools if required 3. mount the EFI partition to /boot/efi 4. grub2-install --target=x86_64-efi The grub.cfg you showed before looked correct to me, the Gentoo GNU/Linux entry was trying to boot off of root='hd0,gpt2' which is correct.
