I'm having a similar issue with my
HP Pavilion g6z-2200 CTO Notebook PC.
The interface for my OfficeJet 4500 Wireless All in One G510n-z said I needed to finish installing it, which I did months ago, so I tried using a back up copy from a Seagate external hard drive I have. It said it couldn't re-install the image.
I then used the install disks I bought with this computer and re-installed Windows 8 and all the Windows Update updates. Then tried to update to Windows 8.1 and am now having a LOT of trouble with even getting my computer to boot. I didn't have this trouble before.
What's going on?
