Bug Description
I believe that installation falied, fatal error: failed to install grub, because a small grub_bios partition is necessary on a GPT partitioned disk. The install was using manual partition (to support a certain use scheme), but the installer did not notice this at the partition selection step.

| summary: |
- Installing on GPT partitioned disk, but w/o grub_bios partition + partitioner does not warn when missing bios_grub partition |
I'd noticed this myself not too long ago. It seems that the check.d/biosgrub script skips the warning if *any* disk is using MBR instead of GPT, and this test typically sees the MBR partition table on the usb stick being used to install from.
