As I wrote earlier, a BIOS boot partition is used by GRUB to store its core image only when installing its boot image in the MBR of the disk. This partition replaces the unallocated "embedded area" located between the MBR and the first partition on MSDOS disks.Then, to proceed, remove /dev/sda1 partition followed by grub-install?
Removing the partition won't help. It is just useless, it does not harm.
If sda1 is a type EEh partition, doing that will probably dig your hole too deep to escape from, absent a full partition table wipe. :-(
What are you talking about ? ee is the identifier for the GPT protective partition in the MSDOS partition table of the protective MBR. This partition is hidden. I am talking about the only real sda1 partition that is visible, the one defined in the GPT partition table and is shown by fdisk as "BIOS boot". Please do not make things even more confused than they are.
