Comment 8 for bug 234835

I had some problems with a swap-partition, which I turned off before starting the installer. I then got these errors in /var/log/messages:

Nov 4 20:20:48 ubuntu migration-assistant: error: /dev/disk/by-uuid/8a215554-46c3-497e-9e30-6062ad7d2b5c does not exist.

I think it somehow tries to see the contents of this drive, and then fails. Or it is the deleted partition between sda3 and sda4.

Does anybody know if the installation finished before this mess, except for grub?
