    Have you tried boot repair from LiveUSB? – Kulfy Jun 25 '18 at 16:45
  • The bios_grub partition is unformatted space containing the core.img file for grub when using gpt partitioning and BIOS boot. You should just need to reinstall grub to gpt's protective MBR. If drive is sda: sudo grub-install /dev/sda from inside a otherwise working system. If that does not work, then a full reinstall of grub, usually easier with Boot-Repair or you can use chroot. – oldfred Jun 25 '18 at 17:44
