I had been experimenting with a Vista-Ubuntu dual boot system recently, and it seemed to work pretty well. Today though, I was having some problems with my iPod and downloaded an update for Vista as one of the steps on the apple site. Problem is, when I restarted my computer, nothing booted up. It just showed a flashing _ at the top of the screen. I had some ancient back-up disks, but they didn't even get a response. I'm posting this from my mom's laptop, do any of you have some advice? My computer I can live without; my music, I can't.
