This morning windows decided to crash on me. It won't boot back up. Luckily I had tried Knoppix a few weeks ago and still had the cd. Honestly, I have no idea how to work this o.s. I'm in the middle of final week at school and have a presentation that needs to be ready for tomorrow. It's a large file and will require around 645MB. I understand Knoppix has the burning software k3b and I've tried to set it up. I've already set my root password so I type that in when prompted. It finds my two burners just fine and I believe the other settings are alright, but when I click OK it says it could not update all of the permissions. Then it closes. I am desperate and have no experience outside of windows and a little dos from back in the day. If anyone could help me before the end of the day it would be MUCH appreciated.
