Low Disk Space warning

[joelstitch]

I am running Ubuntu 10.04 out of a 160GB external hard drive with nothing in it except a few files and the Operating System. When I made the Startup USB Disk I chose as much reserved extra space as possible so I dont know why is showing me this warnign. How do i fix it so the OS has more space dedicated to it?

ubuntu@ubuntu:~$ df -h

This is what GParted says:

Looks like you need more then 4GB for persistence. Here is the howto http://www.pendrivelinux.com/create-...per-partition/.
