Error: partition not found

Yeah so essentially what happened:

Friend convinced me to install Ubuntu.

Gave it a partition.

Got bored of it so I decided to format the partition.

Formatted it as fat 32 (to my knowledge this is what I was meant to do).

Worked a treat got my space back and no issues.

Restarted and then I get an Error: Partition not found and some grub command prompt type thing.

All my stuff is still there and I would love to get it back but if there are no solutions to salvage it then I am OK for reformatting.

Any help would be very much appreciated I don't mind if I can't restore windows as long as there is a way to get my stuff back.

I have the update edition of windows 7 pro x64 and that means I will have to reformat using vista business(I have that too). I also have the Ubuntu 10.10 install.

As I said I just want to get my stuff back (its still on the hard drive). I'm not technophobic I just manage to break stuff.

Any help will be rewarded with a thank you.:)

I only have the USB install and an external hard drive to put me stuff on. But i can make a boot CD with it I'm sure

OK sounds like the best thing i can do for it, Thanks so much for your support will update you on whether it works or not.

Thank you brianzion that was very helpful, Apparently I can now access windows 7 (after Ubuntu install). I really appreciate the help although I have one more question for anyone who knows, How do I remove the Ubuntu partition without repeating this whole episode.

Thanks again.

Sorry to bother too much but should I delete both the Ubuntu and the 3.91 gig one that I assume is grub? I don't mean to be so specific but I don't want the problem to happen again.
