In case that's the cause, I'll add I had Linux installed on what was to become / (/dev/hda5) in my case too. But I'm 99% sure I asked the installer to format /.
I the end, I booted using the live CD (F6, and adjust the line), installed Lilo and used 'update-lilo' then edited /etc/lilo.conf myself. -- crashed on installation, other o/s now inaccessable. https://launchpad.net/bugs/49088 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
