Ok so I'm new to ubuntu and tried it out for a week before i tried to dual boot my system with windows 7/ubuntu 10.10. After the installation there was no prompt for me to choose which OS to boot into. I figured i messed up and wrote over my partition, but when i log in and go to places all i have is file system. I can't find my c drive. I know this is a total noob thing but i would just like to know if my c drive is completly gone forever or should i try and reinstall ubuntu.
