you might have the wrong windows installation selected, try the other one.

edit:
also, try this guide
http://www.screwloose.com.au/windows-10-...cannot-be-found

The missing "system device" might indicate that the system cannot find the correct bcd store. Check where your bcd is located, should be on the active partition in boot\bcd If I remember right Win7 would install it in a separate 'system' partition when freshly installed or on the windows partition in a folder when updated. Check if this partition is marked 'active', and sometimes it helps to assign a driveletter.

There is no driver information in the boot sector.

Thank you to all.
I gave up.
For me, is incredible that the HD would oy work in the nf4 system.
If some of the errors you mentioned would be present, it should not start even there.
Guess it is a clear sign of my ignorance.

Thanks again

@uazzamerican

don't give up now, it's definitely possible to get this to work.

I did everything, even with another hard disk that was a clone of the one I messed with at registry level.

The funny thing is that, even attempting to do a fresh install of windows 7, I am not able to.

Do not know, maybe x99 is really a pain to deal with.

Last time I migrate from an existing x79 Win7 installation to the x99.

Never did a fresh install before on it.

Well, at the end of the day, only the dvd installation worked. With usb no luck, always errors after the first restart.
In any case, now I am with a very new win7 installation with windows update not functional.
That was what I was trying to avoid....
What a nightmare.

@Fernando

The dvd installation was the solution.
No driver needed.
Now the problem is how to update it...

Search for a Win7 SP1 Update Pack 2021.

I have another pc with a Z97 motherboard and win7 ultimate, same version I am trying to recover.
What if I copy the entire "boot" folder?
Could I recover the hd?

@uazzamerican

just the "boot" folder? I doubt that would work.

If you made an image of the drive it might work though.
you can use software like Clonezilla to image your drive (although Clonezilla might be a bit too user unfriendly for you, it's linux-based)

Even used the "dism" command to inject ahci drivers (successfully)
No luck...
Same 0x0000007B error... Does not make sense at all.
