I became curious about Linux-based OS and decided to try out Ubuntu (I'm only familiar with Windows). And here's the problem: I made a clean Ubuntu 12.10 installation using a burnt DVD, and it does not want to load. The BIOS just blinks and nothing happens. I'm currently typing from the "Try without changes" option and Ubuntu itself seems to run fine on my machine, so I'm assuming it's a booting problem. Any suggestions?
