I created a BackTrack bootable USB thumb drive with Unetbootin. It's a 4 GB SanDisk, and the laptop is a Compaq Presario CQ60. After I complete the installation, and take out the USB drive, press enter, and reboot, nothing ever comes onto the monitor. Nothing loads at all. I'm using the 32-bit BackTrack 5 .iso image with a Gnome interface. Should I install with a DVD instead? I do not know what to do from here.
