Hopefully you have you situation repaired and don't need any more suggestions, but I downloaded the owner's manual to check the restore process. The manual is for 3 different models, so I am not sure which one you would use.
First, can you tell us why you needed to restore to system specs?
You state the unit has a recovery partition, so you did that recovery? Did you have options of how to recover the system as far as partitions and such?
I would have to guess the recovery discs are for your personal data.
Only about .1% of folks have to deal with this, but your system seems to be UEFI capable. Not important you know what it is, but if you are in the bios and you see a Windows Boot Manager option along with the drives themselves, you might try that as first boot priority.
