I've had this before as well, i found there are 2 cures to this;

1:- Bios upgrade, go to dells website and download the latest version of the Bios, these are usually windows executables, but you can also launch then from a DOS boot disc of if u have a ERD disk you can run it from that,

2:- Bios option - RAID, imaging fails if the RAID settings are active, you need to try a different raid setting and it will allow this to run, i cant remember what the raid setting i used was but have a fiddle and it should boot up with the image once you have found the right option.

To resolve this issue, consider the following steps:

  1. Boot up the computer with a Microsoft Windows 98 boot up disk or Windows XP recovery console. Select the correct bootup device before you do that.
  2. At the DOS command prompt, type in: fdisk
  3. Now, you will be prompted with the following question

    • Do you wish to enlarge large disk support (Y/N) ?
  4. Enter: Y
  5. Now to check for active partition, enter: 2

    Look under the Status column. The active partition is usually assigned to the drive which contains your operating system.
  6. If there's no active partition set, enter the number of the partition to make active

    Restart your computer and the problem should be resolved.
I hope this is what you are lookin for..I am still tryin to build my profile so ratings especially the good ones really help
