Sorry for not responding, I was away on vacation with no internet access.
Boot to the Command Prompt from the flash drive again. Then enter the following:
diskpart
list disk
list volume
Record the output of each of the list commands and post here please. For instance, on my computer it shows:
>diskpart

Enclosed in code tags to preserve formatting. I know you won't be able to cut and paste but will have to write the info down.
As you can see, I label my drives/partitions so they reflect the drive letter they are assigned when I boot Win 8 normally. Makes it easy to find when booting from other media.
