Wubi

ubuntu 11.10 boot crashes and freezes.

Asked by Ian Ashworth

I am running a laptop with dual boot windows 7 and ubuntu 11.10. I tried to load the proprietary drivers for the ATI mobility radeon premium chip set and the system rebooted before the install and activation was completed. How can I stop the boot process from installing the proprietary driver and just boot with a default video driver?
The system boots to the wubildr O.K. them the screen stays with the background colour wash for about 60 seconds then reverts to a black screen and a verbose boot process which jams up. How can I control the process so that I can tell it to skip the corrupt video config files?
Alternatively how can I read the "root.disk" file and copy my data so that I can do a reinstall?
Thanks in anticipation

Try using 'nomodeset': http://ubuntuforums.org/showthread.php?t=1613132

You can access a root.disk from windows using: http://ext2read.blogspot.com/ or boot an Ubuntu CD (select "Try Ubuntu") and mount the root.disk (you need to know what partition it's on, e.g. assuming /dev/sda2):
sudo mkdir /media/win
sudo mount /dev/sda2 /media/win
sudo mount /media/win/ubuntu/disks/root.disk /mnt
nautilus /mnt

PS the part you need from that thread (there's a lot there), is pressing 'e' on the first entry, then editing the line by adding nomodeset (and you can remove quiet splash as well). Even though it says 'not for wubi' just ignore that (it's the same after the first boot - the install)

Can you help with this problem?
