Comment 2 for bug 96084

Thanks for your prompt reply. I do not get any flashing messages, just the Ubuntu progress bar. Here's what I see when boot drops to the prompt:
BusyBox v1.1.3 (Debian 1:1.1.3-3ubuntu3) Built-in shell (ash)
Enter 'help' for a list of built-in commands.

/bin/sh: can't access tty; job control turned off
(initramfs)

Seeing the prompt response from you folks, I started poking around. In casper.log I have:
/init: /init: 1: cannot open /dev/fd0: no such device or address
(this is repeated a dozen or so times, then at the end:)
Unable to find a medium containing a live file system.

This box has a CD rom, floppy, and an IDE hard drive.
