I meant run these commands

bootrec /rebuildbcd

bootrec /fixmbr

bootrec /fixboot

but only after you have just an optical drive and your unbootable installation drive connected.

@infuscomus
Did it already, same results.
I doubt it is bcd related.
I think that somehow the OS keeps trying to load with a not correct (nvidia?) Media driver and I am not able to reset this situation.

Heck I also used several bcd fixers on Hiren's bootCD that should address any bcd problem.
I am no super expert by I can tell for sure this is not the problem.

It is driver related OR a load sequence that points to a wrong driver.

@Fernando
Yes, but it contains information about the on-board disk drives and their in-use Storage Controllers.

I think you are right.
But how to edit the boot info to put the right driver/controller?

BTW I set the sata controllers to IDE, same.

Update,
I see that using rebuilbcd, it start try to search for a win7 installation.
The result is "0"....
Funny, as the recovery procedure is able to find the installation.
This problem is a real puzzle...

Update2.
It seems it was normal, I had to edit the bcd to process it, with attrib instruction.
In any case, no further results.
Same error.

Done literally everything I could.
MBR and BCD fixed in manually or with several softwares.
Decided to work on a older P45 motherboard, same results.

Tried Paragon adaptive restore, no luck.

I really do not know what the problem is.
It seems I solved every single sorce of 0x000000007b error without getting rid of that.
Incredible...

try using an external OS, and extract all your data (images, documents, game save files, or whatever) from the hard drive inside the computer your using, then do a fresh install
