Some information re: my hardware setup: I have three hard drives in this machine. One came loaded with Windows Vista (Ubuntu's GUI shows it's name as HP), one came installed with some HP-data on it (Ubuntu's GUI shows this as FACTORY_IMAGE; its purpose is unknown) and I installed one drive through which I boot Ubuntu (this is my home folder; it typically isn't mounted). Ubuntu is the default OS at startup.
Last night I installed updates and rebooted. This caused the usual problems of skipping the GRUB menu on startup and disabling wireless (which is the only way I can get onto the internet).
I did my usual solution for the wireless (install a patch from the Wireless card's vendor) and edited the GRUB boot menu (deleting an 'if statement' named "terminal_outputgfxterm").
Last night, everything seemed to be fine. When I booted my computer this morning, though, the monitor received no signal from the computer.
Frustrated, I decided to run the liveCD and run a system restore
I tried to follow the instructions here, believing that I could re-install the on the drive and then restore things to working order with a backup on a separate HD. I loaded the Live CD and went to re-install. I chose the Something Else option, selecting the device /dev/sdb1 (which was type ext4). I also selected /dev/sdb2 as Swap.
I recreated the computer name, password and username identically so I would have minimal problems when restoring the system.
After completing the installation and rebooting, I receive the following error on screen after the BIOS screen
I can only get an OS using the Ubuntu liveCDCode:error: no such device: 25c692af-d8f7-4f25-9083-df10a689f1 >grub rescue
Searching on this subject reveals that this is a problem relating to the boot sectors of the Disk, namely that GRUB is not present. I believe I need to install GRUB boot menu, but I am uncertain. I believe that this is the solution, but I have had little luck getting the liveCD to do as I wish.
Step 2 of these instructions showed two boot devices:
I make the directory in step 3Code:/dev/sdb1 (which has an asterix in the boot column) and is under System (Linux) /dev/sdb2 and us under System (Linux swap /Solaris)
In step 4 I mount the thing into the temp folder, but in step 5, when I open the folder Temp under Home, the GUI shows me inside a hard drive called HP. The third drive (normally invisible) now shows up as 496 GB File System.
I'm now confused and slightly scared - did I just install Ubuntu on the Windows-dedicated HD? Have I ruined my ability to use Windows?
Do I need to format my 3rd HD and install GRUB from there, then get in touch with Microsoft for a system restore?
I'm a little out of my depth, and would like to know what to do to restore both OSes to functionality
