Hi
i want to install ubuntu 11.4 on a system alongside some other linux and windows. i installed the whole system on one partition ( / on /dev/sda12) before completing the installation "migration-assistant" nags that:
Migration assistant wants to mount a partition but /dev/sda10 can not be unmounted.
the "continue" option can not unmount that partition and come back to that menu. "go back" option results in breaking the installation. though it says that the installation is complete but the grub is nut installed and i cannot boot the installed ubuntu.
here is the results of df commant:

ubuntu@ubuntu:~$ df

/dev/sda9 43254272 2224756 38832320 6% /target

it should be mentioned that i can not mount any partitions in nautilus.
Any comment or help will be welcomed!
