Failed because installer failed to correctly configure grub to dual boot.
Grub didn't show other OS (another lucid)
Install failed on a workstation that's connected to the LAN but not connected to the Internet (company whitelisting policy). The installation hanged on 89% (Checking for packages to remove) for over 6 hours. Had to change its mac address first before redoing the install.
Once the migration assistant error had occurred, even restarting ubiquity with --no-migration-assistant wouldn't install. It kept throwing the same error. Had to reboot before install was successful. See comment #64 in bug report.
Grub didn't show the other OS (Ubuntu Karmic)
Hardware test: Intel T7500 (2.2 GHz), 2 GiB RAM, Nvidia 8400M GS, Dell Vostro 1500.
Nouveau renders screen unusable. Requires work-arounds to reach desktop.
