Alright, so here's where I'm at. I tried to dual boot Ubuntu and Windows 7, and had actually succeeded. The thing was, I had 4 partitions and wanted 3, so I went back and booted the live CD of Ubuntu to access GParted. I did two things while there, I had unformatted space that wasn't being used so I unallocated it and created a larger third partition that would be shared between the two OS's. I then renamed the partition Ubuntu was installed to from being unnamed to "Ubuntu" I boot up my PC and it goes to the grub rescue mode. It looks like: error: no such partition. grub rescue> I'm not sure what I'm trying to do now, or how to do anything in grub. Any way I could boot to Windows, Ubuntu, or the Ubuntu live CD? How do I get a permanent fix on this? Sorry for being such a noob. I'm sure I'll laugh at this one day, but for now, I need some help.
Your grub is probably using the drive label to boot from. But Ubuntu uses Grub2, so the configuration is a dog's breakfast, so not sure what is different in that case. If you were using the legacy grub, you could hit 'e' when the grub screen comes up and try to do a temporary modification to get it booting, and if it works make it permanent by going in and editing /boot/grub/menu.lst . But if you've got Grub2, I can't really help.
Alright, so I figured it out. I wasn't sure how to boot from a disc at first till I googled it for my specific system. I booted the live CD of Ubuntu, repartitioned my hard drive, and reinstalled Ubuntu. All's well now.
