As I have a well out of date version of Ubuntu from which I'm installing I followed the instructions from the former verbatim, excepting, obviously, .iso filenames and kernel/RAM paths. CD 1 on 2GB /dev/sda1 partition; sda2 for the system to be installed upon; sda3 for /home. Loads on reboot.
The problem I'm having is that CD-ROM module and device. Tried replacing "/cdrom (I'm sure that's not it, but whatever the default IS) with /dev/sda1 to no avail.
