Hi all,
I have reached new hights in my stupidity and haven't managed to get myself out of this one so far.
I accidentally formatted the partition that contained the GRUB boot loader, so I cannot boot into Ubuntu 14.04 LTS.
Background to the saga:
I have an iMac with OSX and Ubuntu 14.04 LTS installed side by side. And am using REFIND to choose between the two. When I select Ubuntu in refind, I would get the grub boot menu and from there I would select ubuntu to launch Ubuntu 14.04 LTS.
After upgrading OSX to OSX Mavericks I could no longer boot into Ubuntu because I got the error:
error: unknown filesystem
grub rescue >
(During the upgrade process to OSX Mavericks the OSX Installer added another Recovery HD partition, so I now have 2 of those. I think this lead to the problems with my partition that holds the GRUB loader).
However I then went and, in a moment of insanity, did something silly and dug myself a deeper hole:
I booted using an Ubuntu Live CD, and fired up gparted.
Then without really thinking, I changed the filesystem on the GRUB partition from "unknown" to FAT32, effectively also erasing anything that was on this GRUB partition.
What I have tried so far:
1. Set the "boot" flag on this fat32 partition (sda6)
2. Booted into a Live CD
3. Installed Boot Repair in the Live CD instance and attempted to have it repair the boot options and settings.
But it fails and spits out this as a pastebin link:
http://paste.ubuntu.com/7505869/
One of the problems I noticed is that based on what I read, Boot Repair needs to be in EFI mode to work.
However from what I can tell the Ubuntu Live CD is booting into BIOS mode which I think is the reason that Boot Repair could be failing? If that is indeed the case, I have not figured out how to get the Live CD to boot into EFI mode.
Any help would be appreciated.
