Install UBUNTU on USB
 

I installed ubuntu 12.10 on my 8GB USB.. after installation I have left with ~6GB free space.. Now when I try to surf net or open some applications I get error message that I do not have enuf space.

I am working on WIndows 7 Laptop with 6GB RAM..

Secondly, I am not able to access my folders on hard drive. If I change my boot sequence then Windows get started. Any ideas how to get around this?

Welcome to the forums! Can you open a terminal (Ctrl+Alt+T) and copy & paste the results of the following commands, which will list your various disk and RAM statistics?

Secondly, here's an easy tutorial to "mount" (access) your hard drive from Ubuntu: http://www.psychocats.net/ubuntu/mountwindows
