Hi, I installed ubuntu-13.04-desktop-amd64 on a pen drive using Universal-USB-Installer-18.104.22.168, but when I try to boot, the system hangs, and I can't get past the first line (... H. Peter Anvin et al). I have a 64 bit Aspire 5551-A from Acer. I am using a 4GB USB key.
Any help would be appreciated. Many thanks!
