| [SOLVED] Grub installed on wrong HD, now that HD is dead
I have two hard drives, my Raptor is technically my primary HD (physically) although it has nothing but my games on it and Windows/Ubuntu is on the other HD (my real primary drive). It seems when I installed Ubuntu it installed Grub on the Raptor rather than the larger drive that Ubuntu is actually on. So I had Grub on my raptor loading Ubuntu on my other hard drive if that makes sense.
Anyway my Raptor seems to have died so now Grub doesn't work. How can I get back into Ubuntu? If I tell it to boot off my main drive it boots Windows only. |

| The default installation for Grub on most Linux distributions is to install to the mbr of the first hardrive so if your Raptor drive was seen by the BIOS as the first drive, that's where Grub would be installed. This is not automatic like it is with windows where you get no choice but usually the last item to choose in your Linux installation is where to put the bootloader.
Have you removed the Raptor drive? Do you still have the Ubuntu CD? If so, or if you have another Live CD you could use that to reinstall Grub or you could download the SuperGrubDisk and use it to repair your bootloader. Super Grub Disk Official Webpage
Post the output of "fdisk -l" if you have a Live CD to use. | |

| You have to edit menu.lst and /etc/fstab files before re-installing GRUB using SuperGRUB CD.
Boot up from Ubuntu CD, mount root partition of Ubuntu and post the contents of /boot/grub/menu.lst and /etc/fstab files here.

| fdisk -l just attempts to boot into Windows.
No the Raptor is still installed for the moment. I submitted a RMA ticket with WD. Yes I still have a Ubuntu CD. I can boot into Ubuntu from the Live CD (but it doesn't use the version on the HD). Not sure how to tell it to fix Grub and put it on the other HD. | |

| Boot up from Ubuntu CD ( version doesn't matter ), open Terminal and execute this Post output here.

Save files, set Ubuntu Hard Disk as Primary and boot up from SuperGRUB CD.
Select Fix Linux Boot Loader ( GRUB ) option.
