Comment 6 for bug 700910

I tried to reproduce this with a current desktop CD image and failed. I created /dev/sda1 (vfat, 2G), /dev/sda2 (ext3, 7G), /dev/sda3 (swap, 1G); rsynced the contents of the CD image to /dev/sda1; rebooted with 'LIVEMEDIA=/dev/sda1 ubiquity/partman-skip-unmount=true'; applied ubiquity r4687 to prevent an unrelated crash; and installed to /dev/sda2 and /dev/sda3, telling it to install GRUB to /dev/sda1. The installation completed successfully.

If this is still happening to you on current Natty images, could you please describe how to reproduce it, and attach full logs? Thanks in advance.
