when booting, wrong filesystem mounted

[Jeremy Dawson]

This bug occurs when booting either (1) using the desktop CD (Ubuntu10.04), or
(2) when booting off a USB stick previously created on another machine using the Startup Disk Creator
program (usb-creator) (also Ubuntu10.04).

When booting from either of these sources, the machine actually mounts /dev/sdb4 (as /cdrom) and
I believe it actually boots from that partition.

When I delete the partition /dev/sdb4, and then reboot from the CD or USB stick,
 then the machine seems to boot from the CD or the USB stick respectively.

The partition /dev/sdb4 contains the results of yet another failed attempt to install Ubuntu 10.04,
as per https://help.ubuntu.com/community/Installation/FromLinux

Thank you for taking the time to report this issue and helping to make Ubuntu better. Examining the information you have given us, this does not appear to be a bug report so we are closing it and converting it to a question in the support tracker. We appreciate the difficulties you are facing, but it would make more sense to raise problems you are having in the support tracker at https://answers.launchpad.net/ubuntu if you are uncertain if they are bugs.

The question in https://answers.launchpad.net/ubuntu/+question/117116 has expired apparently because it was ignored.

If there is any reason why I should be uncertain that this is a bug, it would be helpful to mention it.

If there is any item in https://help.ubuntu.com/community/ReportingBugs#When%20not%20to%20file%20a%20bug
which is relevant to this bug, it would also be helpful to mention it.
