I am running an up to date ubuntu 9.10 box.  I am trying to boot a virtual
image (I have tried Windows XP, Centos 5.4, and backtrack 4 )

I get the following error:
------------------------------
------------
ata0  master : QEMU HARDDISK ATA-7 HARD-DISK (16384 MBytes)
ata1 master : QEMU DVD-ROM ATAPI-4 CD-Rom/DVD-Rom

Booting from Hard Disk ...
Boot failed:  not a bootable disk

FATAL: no bootable device
------------------------------------------

My system is an AMD CPU, all sata drives (including the CD) and I get the
error whether I tell it to boot from DVD or HD.
