Bootcamp partition Black Screen of Death after restore from DMG file + mbr rebuild

Question

I have a 2012 Macbook Pro 15", and my hard drive died the other day. Thankfully I had a bitwise copy (non-compressed DMG file) of my Bootcamp partition from that morning via Disk Utility, and I had all of my Mac data backed up through Time Machine.
The new disk was installed with the factory default Mac OS. I was told to try and restore the Windows partition before I restored my Mac partition. I spent all weekend and the past two days trying to restore my Windows... I took it to the Mac store and they said this was "not in their skill set to assess".
First through Bootcamp I installed Windows 7 (I still have the original install disk!), then I restarted in the Recovery partition (that comes with Mac) to load the DMG file onto the Bootcamp partition. I had to load the DMG file into the source files on the left of Disk Utility by clicking it twice, and then selected all the files as the source image in the "Restore" tab of the Bootcamp drive, and the Bootcamp partition as the destination. Everything went smoothly as far as I can tell.
Here's where things go south. I restart, after the image is loaded onto the Bootcamp partition, into Bootcamp and I receive a "Missing Operating System" error.
I then run through all of the bootrec.exe functions
bootsec.exe /nt60 all /force (which resulted in "Bootcode was successfully updated on at least one volume.")
I ran DISKPART to flag the partition as active and navigated to Partition 4 (Bootcamp) and the readback was
"Partition 4 Type : 07 Hidden : No Active : Yes Offset in Bytes : 320108232704 Volume # - Volume 1 Ltr - C Label - BOOTCAMP Fs - NTFS Type - Partition Size - 165 GB Status - Healthy"
chkdsk C: /f went well too if I remember correctly.
The only part that keeps my hopes up is that from Mac I can see all of my Windows files, it recognizes the Bootcamp partition, and everything is right in place. Any help is greatly appreciated! Also if anybody knows a better way to restore Bootcamp from a DMG please let me know! Thank you so much in advance for any feedback you may be able to provide. I can boot from my Windows installer and run any commands, and terminal is a thing
