Thanks I also saw this message when I was searching threads for help but I can’t make a bootable CD because I’m on a netbook that doesn’t have a CD drive…and my notebook that does is the one with the problem and won’t boot.

I’m pretty desparate now and have taken deparate measures. I am now using Acer Recovery Management to restore my system but with a back up option. The restore system has taken 17 minutes to back up 5% of my files… I’ll know in a few hours if this works.
