Windows 8 system image restore failed (Error 0x80073B92)

I bought a new Asus laptop the other day and I removed Windows 8 and installed Ubuntu 13.04. Now I'm trying to reinstall windows 8 from a system image but it fails.

I have an ASUS Q550L (https://www.asus.com/supportonly/Q550LF/). I used Windows 7 Recovery tools to create the system image on an external harddrive and a recovery disk. I booted from the recovery disk and went Troubleshoot > Advanced Options > System Image Recovery. The tool appears to be working, it repartitions the drive and all that, then when the progress bar reaches the end I get a warning popping up:

The system image restore failed.

Error details: The requested system device cannot be identified due to multiple indistinguishable devices potentially matching the identification criteria. (0x80073B92).

I click close, and restart the computer without the dvd in, and I get this prompt:

error: unknown filesystem.
grub rescue> _

I have tried all sorts of iterations within the BIOS menu, CSM enabled/disabled, Fast Boot enabled/diabled. But they all lead to the same problem. Any ideas?

EDIT: Interestingly, when I boot from the Ubuntu live DVD and click install it recognises that windows 8 is on the computer (i.e. it gives me the option to install Ubuntu beside it). Is there a windows equivalent to boot-repair?

EDIT2: Following the advice of magicandre below, I booted to the Windows 8 Repair DVD and went to the command prompt to try diskpart:

DISKPART > list disk

Disk ###  Status         Size     Free     Dyn  Gpt
--------  -------------  -------  -------  ---  ---
Disk 0    Online          931 GB      0 B        #

DISKPART> select disk 0

Disk 0 is now the selected disk.

DISKPART > list partition

Partition 8    Unknown          8075 MB   903 GB
Partition 5    Recovery           20 GB   911 GB

Background: I did initially install Ubuntu as a dual boot, but it didn't behave nicely so just got rid of Windows and did a full install of Ubuntu.

I need to reinstall windows 8 because the battery won't charge and I need to return it to windows 8 to a) see if Windows 8 can charge it, and b) return it to the store if not.

This question isn't about the battery, I already had some help on that here (Battery won't charge on new Asus laptop (ubuntu)), any other thoughts on that issue are best sent there :-)

From John Zollar What you need is get a live suse linux disk (it is free ISO download from suse.com site)toget access to the hidden partitions containing the restore files (there are like 4 hidden partitions, the one you need to copy is to an external usb drive is the biggest one containing the install.wim file) and copy the install.wim file to an external usb Hard drive. Then try to make a bootable USB using the largest capacity stick you can get. A 32 GB should do it. My install.wim image with all the windows 8 driveras included in the operating system was 22GB. The install.wim image contains the windows 8 operating system plus all the native drivers for your laptop. you can use The Windows® Automated Installation Kit (AIK) to extract all, the Windwos OS + drivers to a file and place that content in the source file of the bootable USB. Read about WAIK at microsoft site. I also recommend finding site with methods of making a bootable USB with not less than 32 GB capacity. Well At least you have an idea of how to look for the rest of the information to make a Windows 8 Recovery usb stick. John
