Hi, so I'm relatively new to Linux. I'm trying to put BackTrack 5 on my USB stick. I formatted it, and used Unetbootin to set up the USB. When I booted into it, I got this error:
(initramfs) unable to find medium containing live file system

However, when I went to my desktop computer, it booted into the USB just fine and gave me the option to start the graphic interface, and etc. Why would my laptop be unable to boot into the USB? I tried using both USB ports.
