According to: |

"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 |
30 |
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 |
31 |
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 |
32 |
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. |
