I found this trick a while back working on people's computers. As long as the partitions are in tact, you can boot with Grub (Yes a linux loader), on either a USB, CD, 3.5" disk, whatever.. and the image on the partition of the hard drive that is not normally seen will be a bootable image under the grub auto loader.
I've never tested this with Dell's, but I know it works with HP/Compaq. Might be worth a shot
To to recap the issue. If you have a ghost image on a hidden partition that you didn't burn to a CD and the drive partitions are still in tact. Use grub to boot the recovery partition
But I see you fixed it... hopefully this can be of use to someone else.
