I wanted to make my pc load xubuntu from only a flash drive. I used unetbootin and had it make me a xubuntu 12.04 boot drive on a 4gb drive. I booted up my PC and got to the first options page where it says "Install", "Try without install", etc. I tried to install but I can't move forward because it says I need a minimum of 4.3 gb( I think it's 4.3 but can't remember now).

I used the 12.04 Desktop 32bit version for unetbootin. I wasn't too sure about the "Alternate" version. Could this be why I can't use a 4gb stick?

I might have to use another light-weight linux, if I need more than 4gb.
