Simplex - Heads-Up!

I need help restoring /my Windows-7 Pro Boot Manager.
I inadvertently destroyed it by prematurely disconnecting the C: Hard Drive.
I recalled that I did the same thing about 10 years ago.
The "Fix" was to use the Repair Function of a Windows-7 Install Disk.
I tried to use the "Fix" but now it fails.
Windows claims I must use the same Version Windows-7 Disc as I am attempting to Repair.
I have several Windows-7 Install Disc, to include the one in question, matching the failing one and not Booting.
None of them work!
After finding and reading a response to a Post by F22-Sim Pilot a Bell went off.

I use Simplex on a monthly basis.
My guess is Simplex modifies the Boot Manager "VERSION" on the C: Hard Drive.
Thus, Windows reports I'm using a wrong Version of Windows-7 Pro.

Reinstalling Windows and Simplex would work however, I struggled for days getting Windows Activated.
I do not know any way around this, do you?
I would greatly appreciate your feedback / suggestions.

I have tried the Startup Repair from multiple Installation Disks.
They have all failed!

I am confident that whatever the Startup does, it includes repairing the Boot problem I am having.
Symptomatically, I have seen it before.
I recognize the error I made and need an alternate recovery method other than Startup Repair.

The PC in question is an All-In-One.
I was in the processing of upgrading from a 1TB HDD to a 4TB SSD.
Accessing the Disk Drive Bay is not necessarily easy, thus one of the reasons for the upgrade.

I had just completing installing the 4TB Drive and struggling to Activate Windows-7 Pro, for almost a week.
Once Activated I was rushing to uninstall the 4TB Drive, remove it and replace and Clone it with another Drive.
The thought of putting the All-In-One back together and being able to use it for its intended purpose, caused me to mess up.
With all that being said, I Posted to get an alternative to Startup Repair.
Without Startup Repair working, the PC will not Boot, thus I need a Stand-Alone solution.

I will now begin to try the responses I have received.
Then I'll conclude that Simplex does something that causes Windows not to recognize the Repair, thereby protecting what it's done.
If they all have failed, I'll begin the O/S reinstall process, already dreading trying to do another Windows Activation.

Thanks again for your response.
