I have a Sony Vaio Z21 under Windows 7 x64 with RAID-0 setup.

I installed WUBI.

But when I reboot to Ubuntu, I get the following message :

Completing the Ubuntu installation
For more installation boot options, press 'ESC' now ...

The volume may be already mounted, or another software may use it which could be identified for example by the help of the 'fuser' command.

Why do I see this error ?

How to solve ?

Even on normal installs it's not working for 12.10. I don't think raid 0 is possible for Wubi. pad.lv/1072125 –  bcbc Feb 21 '13 at 19:55
That means Ubuntu 12.10 is incompatible with hardware RAID ??? –  Jalil Feb 21 '13 at 20:43
I think you can use the mini ISO or install 12.04.2 using the alternate CD and upgrade. Honestly don't know enough about it, but Wubi is generally for trying out Ubuntu, not dealing with RAID. –  bcbc Feb 21 '13 at 23:03
