The Ubuntu live-usb created by ultraiso or unetbootin won’t boot due to the new image file since Ubuntu 10.10. It can be solved by replacing ‘vesamenu.c32′ file or editing ‘syslinux/syslinux.cfg’ to add “#” before “default vesamenu.c32″.
There’s a program Image Writer that can create bootable Ubuntu live-usb without this problem.
This utility is used to write Ubuntu img files to SD and USB cards.
Simply run the utility, point it at your img, and then select the removable device to write to.
This utility can not write CD-ROMs.
