Thread: Trying to boot 11.04 Alternate from USB

hi,

have used ubuntu 11.04 alternate download , used install onto 4gb usb. partitioned usb manually 3gb primary , 1gb swap space. added grub bootloader onto primary partition because there no harddisk in system, , os want installed. have set bios boot usb. appears configured either partitions or boot loader incorrectly because when try boot blinking underscore in upper left screen.

ran boot_info_script.sh found @ http://sourceforge.net/projects/bootinfoscript/, , have pasted results.txt below.

ideas on how can fix this?

thanks,
