What I suspect you removed was a very small, 1-2M approx, FAT32 partition, flagged as
bios_grub which is essential for using GPT partitioning in a BIOS/MBR system.
Using a legacy (not UEFI) live boot to any of the Ubuntu family of OSs run gparted and create again that small
bios_grub partition, probably at the start of the disk though I think it can be anywhere on disk. You may then be able to install grub again from the live system, using command
Code:
sudo grub-install /dev/sda
assuming you have only one hard disk /dev/sda.
I am assuming here that doing this in a GPT formatted system still works as it used to on msdos formatted system but you may wish to wait for more replies before going ahead with this final command.
