[Bug 925296] [NEW] 11.10 fails to boot from usb with "Boot Error"

Thu Feb 2 06:26:29 UTC 2012

Public bug reported:

I downloaded ubuntu-11.10-desktop-amd64.iso and attempted to make a
bootable USB drive to install it with.

I used two different (both new) USB drives and tried with both usb-creator-gtk and unetbootin to boot both a desktop and a laptop. in all cases I simply get a black screen with "Boot Error" before grub starts. 
I also tried creating the image with 11.10 and 11.04

one clue is that I see this message on (only) one of the systems I tried
to use to create the image
