Use existing Physical External Disk

Hi,
I currently have Ubuntu installed on an external disk (using the full disk).
Is there any way that Parallels 6 can use the full disk to book Ubuntu?

I've tried using the bootcamp option and marking all the partitions but that doesn't work (no boot device found).

Cheers,
Trevor

 

It should be usable as a a Boot Camp disk. How is it formatted? Does it contain BIOS boot code in the MBR? What do the following commands say about the disk? (replace 1 with the number of the disk; use diskutil to get a list of all disks)

Code:

diskutil list /dev/disk1
sudo fdisk /dev/rdisk1
gpt -r show -l /dev/disk1
sudo dd if=/dev/disk1 count=1 | xxd

Make sure to backup the xorg.conf file because Parallels might mess it up (if you get it to boot)
