manual powerdown -> Grub doesn't recognize fs

I was using Ubuntu (Breezy) and it crashed (a rare occurence) so I had to manually turn the power off using the power button on my computer.

But then the next time I turned on my computer, nothing booted: the manufacturer's screen just stayed there. I was able to get it to the point where it got to the boot screen, but after boot from CD was displayed it didn't show GRUB, which I fugred out to be because my second NTFS hard drive had somehow become an active, bootable druve,

So anyway, once I got that fixed, it now says Grub loading, please wait... Error 17, which is when the partition exists but the file system can't be read.

So did my manually powering off Ubuntu somehow cause the file system to be wreck, by not unmounting it or something? I am a complete linux noob and I need help! I tried using my various rescue disks. PartitionMagic says the file system is Ext2, and Acronis says the type is Linux Extended, but the filesystem is "None," and I can't seem to be able to change it. They also indicate that there is no free space in the partition.

When I use the Ubuntu Live CD, it recognizes the Drive and Partition but not the filesystem (it says "Unformatted"). Is there any way to make it work? I don't think I have a problem with grub or the mbr or whatever, just the filesystem not being right. I need some of my files on the Ubuntu, and I need to preserve the Windows installation too. Right now, if I could just boot either, that would be great. Oh, and if you have any suggestions, could you spell them out for me, because as I said I'm a complete linux noob. Thanks.

You said Ubuntu Live cd, is that where you get a gui (graphical interface) when you boot?

if so have you tried to mount your ubuntu partition from the live cd?

With no filesystem ???.
I'd be looking to run testdisk (or gpart if you prefer).

ahsii: yes, I have tried to mount it but I don't know how in the LiveCD and the filesystem is corrupted anyway. Someone on the UbuntuForums says that my partition is corrupted and I'll have to lose the installation. Does anyone know a good data recovery program that I can run from a CD, and if I format the Ubuntu partition will grub still be installed, and if so, how do I uninstall it? Or if I reinstall Ubuntu, will grub work...
