Okay guys, I had a bit of a problem with my PC earlier. Not sure what happened, it just crashed in the middle of me playing a game and when I restarted it's now telling me I have no operating system or hard disk.
Luckily I have a USB I can use to boot Ubuntu. However, even that is giving me problems. I try to install, but it gives me the "No root file system is defined" error message. But there's no option to create or select a partition, the table is just empty. When I click the 'change' button it just crashes out and takes me to the Live Ubuntu (the trial version, basically, where you can't keep any files because they will all be gone when you restart.)
Is there anything I can do? I really can't afford a new computer.

? Does gparted show a device /dev/sda?
