I experienced problems booting the install-CD for both Ubuntu 7.04 and Fedora Core 7 on my HP Compaq 8510p laptop because the kernel didn’t have the correct SATA driver, so I decided to try the beta of Ubuntu 7.10.

The booting problem was fixed on 7.10 Beta and the installation process halted at 88% “importing documents and settings”.

The solution I came up with was to disable the migration tool and then run the installer from a terminal window with the following option:

ubiquity --no-migration-assistant
