Here's an update on my experiences. The Dell "Backup and Recover Application (BURA)" upgrade to create system images does create images, but there is no way to use/recover them. They can't even be recovered using the hard disk boot drive option from the
restored "factory image". This is the method suggested by Dell support as the way to do it since you can't produce bootable media for it. I uninstalled Dell's "BURA" and got a refund for it's $39.99 "upgrade".
One of Dell's support techs reduced the *:winretools" partition on the OS hard drive from 500MB to 499MB, which then allowed me to create a "Windows7" system image (of my Windows8 system) to another internal hard drive. But it was of no use since the recovery
media could not find/recognize that hard drive. So, created another image on a network drive (NAS), which the recovery media could find and I was able to successfully re-image a "new" hard drive (of the same size as the original - 2TB).
Microsoft level 2 support said that the problem was that my backup 3TB internal hard drive was a "primary" GPT partition (rather than a smaller 1TB MBR I guess). About a month later I discovered that I could no longer create images on the NAS. So, I tried
again on the internal hard drive (which fortunately worked that time).
Shortly thereafter Windows stopped being able to shut off my computer. After forcing shutoff (via the power switch) and restarting, Windows wouldn't boot. Dell's repair application (I believe which started automatically) couldn't fix it and seemed to make
it worse. None of the Windows8 recover options worked either (because of the partition re-sizing?) So, I re-imaged the hard - drive from the 3TB internal drive image.
Windows still can't shut off the computer, but it can re-start it (for software updates), so I haven't tried to fix it. Also, it can be safely shut-down with the power switch after the screen returns to the "Space Needle" after trying to shut down for a
while. It can also start safely from "Start Windows" in the boot/repair options. I'm going to avoid using either the Windows* or Dell Recovery tools - they'll likely break it again.
The bottom line - don't assume that either the image(s) you have created will work or that the Dell or Windows8 recovery options will work (especially after re-sizing OS disk partitions) unless you try them.
Good luck - I share your pain!
