[Bug 1155993] Re: GRUB error after Ubuntu Raring desktop amd64 install

[Rehan Khamaruddin]

Update:

Well, I bit the bullet and used boot-repair to try and revive the
unbootable 13.04 install. I used the instructions in the Ubuntu wiki and
installed boot-repair and then ran the summary first (and it saved my
life). The summary showed all my Bootit partitions with full info on
start and end sectors. Encouraged by the depth of info gathered, I
decided to trust boot-repair and click on the "repair" button. It went
off to do some more magic and then cambe back and gave me some commands
to try and run in a terminal. It turns out that grub-efi was installed
whereas grub-pc was required. Yes, I have a UEFI bios but am running in
legacy mode because many of the installed OSes on this hdd predate the
current motherboard. The commands provided ran without issue and grub
was installed to sda1 (as I selected on the configuration screen).
That's when things began to go south. I should have quit at the point
when I saw that grub was installed correctly to the partition of my
choice. Instead, I went ahead and clicked "Forward" in the boot-repair.
It promptly proceeded with hosing the mbr on both my installed hdds and
very thoroughly wiped the bootit partition. Luckily for me, I still had
the boot summary (see above) and used that to reconstruct my bootit
partition and got back all (hopefully) my other OS partitions. I need to
verify of course. Just thought I would share this information for the
benefit of other lost souls who might stumble upon this page.
