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.
