Can you mount /dev/sda1 ?

Of course.

Then this should fix things:

- Reduce sda1 and its filesystem by at least 1MB and change the partition type to "Linux filesystem" (or remove the bios_grub flag).
- Create a new 1 MB partition with type "BIOS boot" (or bios_grub flag).
- Reinstall GRUB in /dev/sda
