I'm not sure if this has been solved, but I have the same problem.
When installing 8.04.1 server LTS from a USB stick on a brand new machine that
does not have a CDROM, the installation fails at CDROM detection.
SOLUTION:
Get a shell (ALT+F2) and enter:
$ mount -t vfat <your_usb_stick_device> /cdrom
and the installation will continue. In my case, it stopped again saying that the
cdrom could not be read properly. Looking at the output on the ALT+F4 screen,
there was a message like:
/cdrom/dists/stable/Release
was not found... Serious bug... There ain't no 'stable' directory, but only one
called 'hardy'... Tried to link hardy->stable, but it did not work (vfat file system).
So I just copied the entire tree:
$ cp -pR /cdrom/dists/hardy /cdrom/dists/stable
And the installation continues smoothly 'till the end.
