Unknown File System, GRUB rescue: Win7 & Ubuntu dual boot problem


Hi guys,

I need some help after installing my new SSD.
Ill run through my old system and explain what I have changed.

I was originally running:
1 x Intel SSD with Windows 7 boot files
1 x Samsung HDD with all other files (games, music etc)
1 x External HDD for backups.

I decided to buy a new OCZ SSD 6Gb/s yesterday and decided to install windows 7 home premium to the OCZ SSD. Everything went fine and I pointed all the locl files to the Samsung HDD. Windows worked fine. I then whiped the old Intel SSD and installed Ubuntu 12.10. This also worked fine. It was not linked to either of the two drives.

After installing a few things on Ubuntu I went to boot back into my Windows SSD after changing the boot priorities and it still boots automatically into Ubuntu. If i do a boot overide into the OCZ Widows SSD then it loads straight into a command line screen that has:


error: unknown filesystem.
grub rescue>


I cannot boot into windows at all and if I try the windows recovery disk then that tells me it has been fixed and it all works. Clearly lying to me.

I have had a look around on some forums but all I can find is people having this problem with one partitioned HDD with a fix for that specific situation that doesnt work on mine.
Ive tried the whole set root and set prefix in the grub rescue.

HELP!!!?!?!

If the Boot Repair utility doesn't solve your problem, boot Ubuntu and go to the site below, read the instructions and download and run the bootinfoscript. If you don't understand the output (a results.txt file), post it here:
