Okay, so I downloaded lubuntu because I think the computer I'm using I think will run faster on it. At first I just put the ISO onto the usb stick (which is a Super Talent USB2.0 2gb). When that didn't work I looked up the proper way to boot from a flash drive. So I used UNetbootin. When I tried to boot from it, there was just a blank black screen with a blinking _ for about ten minutes. That seemed a little too long so I figured something was wrong. Can anybody help me?

My system:

Pentium 4 - 1.8Ghz
494.8 MiB RAM (I think it's DDR)
30Gb Hard Drive
Ubuntu 10.10 (Maverick)
