Comment 4 for bug 106674

duplicate bug of #99004 and #97536 fyi.

i also had this problem. an earlier gutsy disk i had doesn't have this problem, and lets you choose whether to use import manager or not.

for those too lazy to read the link:

run "ubiquity --no-migration-assistant" in a terminal or press alt-f2
you might need to shut down ubiquity first (i did) in order to get it running, so in a terminal run "pkill ubiquity"
