Resolved W7 Pro HD won't boot in new Motherboard

There may be a simple answer to this problem but "Googling" shows that W7 is very fussy.
This hard drive was running W7 Pro SP1 64 bit quite happily on my Gigabyte motherboard. This is an installation from a Dell DVD marked as a Reinstallation Disk which came with COA marked OEM Software.
I renewed my motherboard with an Asus M5A97 R2.0 and connected up my W8.1Pro / W7 Pro (both 64 bit) and my 32 bit Vista Business HD.
The W8.1 booted without any hassle and I installed the Asus Drivers from the DVD as required.
The Vista HD booted and I updated the Drivers - no problem.
The W7 will not run or Repair and I've done all suggestions I could find on Google from obviously many many W7 users who have this problem once they've changed the motherboard.
The answer may very well be for me - a Reinstallation Disk.
Any ideas? Neil.

 

Tip: Microsoft's "OEM" versions of their Windows Operating Systems die with the motherboard.

 

Thanks Doc, you made my day. Neil.

 

Sorry but, I'm just the messenger.

 

When it's too good to be true....
I see from the Googling I did that W7 seems to be real picky if you change anything on the board or the board. Neil.

 

Yep. Microsoft said it had to tie their single-use OEM version of Windows to some part of the computer, and they decided on the motherboard. So, unless it's an identical replacement for a failed motherboard, you're actually breaking the contract, (EULA).

 

So let me get this straight--If the motherboard dies, toss the O/S too?

tnx

 

Yep. That's one of the reasons why the OEM (System Builder) version is cheaper than the Full version.

 

In the words of ABBA - Money Money Money.
It was obviously my OEM DVD that filled the bill but not all the Googled problems are/were, so W7 in all it's versions must create a heap of unhappy users when they have to change the motherboard. Neil.

 

Very true but, this information is in the Windows EULA (end-user licensing agreement) and as users, we agreed to these terms when we started using the software on the original computer (motherboard), which does make it legally binding.

The Windows Operating System software on a disk "branded" with a computer maker’s brand name, or labeled with "OEM ", "OEM/System Builderâ€, "Upgradeâ€, "Academic Editionâ€, or "For Distribution with a new PC only ", is not transferable to a "new" PC (or "upgraded" motherboard) under any circumstances. It is inextricably tied to the "original equipment ".

So, to ensure you don't put yourself in legal jeopardy, it is important to understand it is illegal to use these 'OEM' versions that come with, or were purchased for one computer (or motherboard), on another computer (or "upgraded" motherboard).
