Reinstall Win-7 PRO x64 OEM , no discs

So often I have seen my request by others only to be told, it cannot be done.
I don't know where to turn to

... thought it would be worth an ask

Purchased Lenovo e540 in Aug-2015, 2 weeks later I had a stroke without ever taking the laptop out of the box.
Nov 2016, unpacked the Lenovo and activated/registered online with MS.
- back into its box
May 2017, I successfully made a clone of the HDD_1 onto HDD_2 using free AOMEI BackUpper
- cleaning junkware off HDD_2 after using Revounistaller PRO HDD_2 would not boot
Jun-2017 local PC Shop installed non Lenovo Win-7 PRO x64 along with a lot of commercial programs I did not want.
They charged $200 to reinstall Windows ... about 1\3rd cost of the Lenovo (my problem)
--------
somewhere in here I screwed HDD_2 (500GB) trying resize C:\ partition to clone to SSD (215GB)
Jun 2017, trying to clone HDD_2 (500GB) onto a 125GB SSD
- free AOMEI BackUpper is partially crippled and will not allow editing partition sizes on smaller SSD during cloning.
---------
- HDD_2 using free MiniTool I tried to resize C:\ partition to clone onto HDD_1
- HDD_1 would no boot
26-Jun-2017, Purchased AOMEI BackUpper PRO + AOMEI Partition Assistant PRO
HDD_2 as OS and broken HDD_1 USB connected ,
- Recover Partition (5 hour scan) with AOMEI Partition Assistant PRO found nothing
- proving the HDD_1 is dead

HDD_2 MS Safely Remove not listing all connected devices on Lenovo
- ran Brinks Notification Area Icons - Reset BAT file to clean Notification Area
After reboot no MS-SR atall
- I tinkered in Services and turned on anything that looked like MS-SR
- now I have MS-SR but no list of connected devices (all USB) and 50% of "services/programs" are not listed at all in Notifications list ...

In desperation I concluded a fresh reinstall of Windows is the only path I can see

I do have Win-7 PRO x64 ISO (Digital River Media update) phantom SP2, downloaded before MS shut down Digital River.
- and I have a range of info/numbers/strings given to me by the PC shop about 2 weeks ago

I would be very grateful for any help to dig my way out of the hole I have dug for myself into.

If this thread needs to be moved please do so ... I didn't know where to start thank you

Can I reuse the activation code when I clean reinstall Win-7 PRO x64 ?

Depends what type of activation code it is.

That is why you use pidcheck to tell you if it is oem, oem-slp, or retail.

@ Megahertz07
Which win 7 brand came with the Laptop?
Lenovo OEM Win-7 PRO x64

Does it have a COA stick with a key on it? Look under the battery.
Yes

Did the shop that installed the Win7 pro give you the MS installation disk?
No ... Lenovo do not provide Disks only a Recovery partition

I had already activated the Win-7 OS last November 2016
Laptop was with IT Shop because the PC would not boot.
In post #1 ... I corrupted system partition with bootable MinTools (BMT)
- Before apply changes in BMT I could not read some of the "changes list" so assumed everything was OK
- but BMT GUI cannot be dragged nor resized.
- lesson learned: I will use AOMEI Partition Assistant PRO to resize partitions in future

Lenovo only allow one attempt at making a Recovery disc and then the wizard wipes Recover Partition
Now I cannot find those disks

I did attempt a Partition Recovery ... after 5 hours no files at all in System Partition

If not, it was probably a pirate copy.
It is not a pirated copy because I activated the OS online with MS. No problems

To install Win 7 you must have a activation key.
The sticker with battery is for Win-8 PRO x64, but Lenovo pre-loaded Win-7 PRO x64
at first MS rejected the OS (with IT Tech) because there had already been 48 re-activations
- after phone calls to Lenovo and MS ... MS agreed those multiple re-activations were for a group of Lenovo PC all preloaded with Windows on the same manufacture date
(all beyond my expertise)

@ SIW2
I downloaded Ultimate PID CHecker
I dont know what I should be looking for ... should I post image of PID results here. ?
U-PID matches the the list of keys the PC Tech gave me.

In the past Brink has advised to never post results of OS info in threads

Clean Install Windows 7
I dont have disks, other than the failed recovery disks I made using Lenovo feature.
Nor did the PC Tech give me any disks for the non-Lenovo OEM that they installed

This is a new Lenovo Laptop that has never been used, other than to activate on line in Nov-2016
- it was unstable from day #1, lots of lagging images (resembling failed ScreenUpdating)
- and slow WinExp responses
- I will never buy a laptop again, because of the bloatware that Laptop manufacturers install.

@ Megahertz07
I found What if the MGADiag.exe is ran and then What? to try and understand how to "translate" the results of MGADiag.exe into something I can understand.

I have used "Ultimate PID Checker" ... and I think the results of that indicate all is well. (?)
- but then I am not running Lenovo OEM any more
The non-Lenovo OEM was installed by a local PC shop, they have several branches on the east coast of Australia.
- when I was working full-time they built multiple machines (over several years) for me to run AutoCad

The laptop came with Win-8.1 PRO x64 upgrade disks, but the Lenovo was preloaded with Win-7 PRO x64
- I originally activated the Win-7 on line with MS without any problems.

I am holding 3 TXT files "Reports" I have created with suggestions by SIW2 and Megahertz07.
- but I do not like the idea of making those reports public in this thread.

Win 7 PRO x64 ... non Lenovo OEM
