No OS found on usb drive

[Tony Kernan]

I have a Dell Inspiron 15, using Maverick. I have kubuntu installed. I try unetbootin and when I boot from the usb drive no operating system is found. Unetbootin used to work in Lucid. I found that formatting the usb partition with fat32 works, anything else does not. With fat32 I can successfully use usb-creator. I installed a clean version of Ubuntu on a separate drive, neither usb-creator or unetbootin worked worked with anything other then fat-32.

usb-creator-kde Version: 0.2.25
unetbootin Version: 494-1~maverick1

kernel 2.6.35-22-generic

I have the same problem in Debian Testing (Squeeze)
I have opened a bug at Debian:

I still have this problem. Does anybody have an idea?
