Xubuntu 9.10 LiveCD on USB fails with error can't open /dev/sr0: no medium found

Question

Using Ubuntu's USB Startup Disk Creator (usb-creator-gtk), I created a LiveUSB from the Xubuntu 9.10 LiveCD. When booting, it stalls up with the Xubuntu mouse splash screen displayed.

In attempting to troubleshoot, I used Ctrl-Alt-F1 to check out the first virtual terminal. On that screen, I see over and over again the lines:

stdin: I/O error
stdin: error 0
/init: line 1: can't open /dev/sr0: No medium found

Answer 1

This appears to be caused by a reported bug: https://bugs.launchpad.net/ubuntu/+bug/500822

Answer 2

I didn't find the answer elsewhere, so I decided to document my findings on superuser.

If you just wait a really long time, xubuntu will give up trying to access /dev/sr0, and then the live-usb image will boot.

There is probably a trickier way to get the problem to stop happening.

Answer 3

I disabled the floppy controller from BIOS, and it boots up normally.
