Hi all,

I find several guides on doing the opposite; booting an existing Windows partition under Ubuntu using VirtualBox, but I can't seem to find guides explaining how to do this the other way around.

I have the following harddrive setup, dual-boot configuration:
Disk 1: Windows 7 x64 installation (partition 1), Data partition (partition 2). Both are NTFS formatted.
Disk 2: Ubuntu installation.

I would like to be able to boot the Ubuntu installation from within Windows using VirtualBox. How do I do this with Ubuntu?

I've found a guide explaining how to do this with arch Linux, but I don't think this approach will work directly with Ubuntu and I'd like som assistance in modifying the process accordingly.

All help greatly appreciated.
Thanks!
