Hello Jackman33,
Here's how it works on Windows 8:
Once you use the Win 7 Recovery Option to create a System Image, you have three ways to restore that image if required:
The first method is to create a Rescue Disk which is done as the last step of the System Image creation process or on demand.
The second method is to create a USB Recovery Drive on demand.
The third method is to use your original installation DVD and select the repair option.
All 3 of the above methods are invoked at boot by selecting the BIOS boot menu from the splash screen and then selecting the proper boot device (eg, DVD or USB). It is also important to note that you select the proper boot option that matches your installation configuration (UEFI or Legacy installation). So, if you want to use, let's say, the installation DVD, you might have two options that look something like this:
Boot from:
CD/DVD (Legacy)
UEFI CD/DVD
However, I would recommend that you skip all the above and make a quick migration to a free 3rd-party System Imaging software because the steps are slightly changed in Windows 8.1 and, in some rare cases, the rebranded System Imaging function doesn't even work properly.

I personally use Macrium Reflect free and highly recommend it:
Macrium Reflect FREE Edition - Information and download
Good luck with your decision on this issue.
