Comment 49 for bug 568050

Hi,

I had the same problem as you guys and I found a workaround. I booted up the live cd and opened a terminal where I wrote:
ubuntu@ubuntu:~$ sudo dmraid -ay
RAID set "nvidia_afhibbhj" already active
RAID set "nvidia_afhibbhj1" was activated
RAID set "nvidia_afhibbhj5" was activated
RAID set "nvidia_afhibbhj6" was activated
RAID set "nvidia_afhibbhj7" was activated
RAID set "nvidia_afhibbhj8" was activated
RAID set "nvidia_afhibbhj9" was activated
RAID set "nvidia_afhibbhj10" was activated

and then I started the installer on the command line using this command:
ubuntu@ubuntu:~$ ubiquity --desktop %k gtk_ui

Now the installation goes through, but for some reason, the installation of the boot sector fails, so the result is a machine that does not even load grub when it is started.

I will have to investigate this further tomorrow.
