I'm fairly new to linux and really new to elementaryOS While trying to format a thumb drive i accidentally deleted the grub partition from my hardrive. I quickly created a bootable USB with "Boot-Repair", and rebooted. Now im loaded in the "Boot-Repair" live USB, and when i try to run "recomended repair" i get this errer message: "GPT detected. Please create a BIOS-Boot partition (>1MB, unformatted filesystem, bios_grub flag). This can be performed via tools such as Gparted. Then try again." When i open up GParted i see the empty space that was my grub partition, but im not sure what to do with it. I have tried creating a new partition and leaving 2mb unformatted but A) i dont know what format the partition should be, and B) dont have the option to "manage flags" (its greyed out) i don't want to have to reformat. I'm hoping i can just re-install grub in the empty space i now have now. Please help. EDIT: This is what GParted currently looks like for me imgur.com/OeL7LRc.jpg
