Windows 10: Old Win 7 key - new Win 10 HDD install question ...

I paid retail for 3 copies - "Family Pack" - Win 7 Home Premium many years ago. They all 3 use the same install key. I am now finally getting around to investigating Win 10. Previously I only used two of the 3 as Win 7 and never actually activated one of them. I just now have installed one of them for Win 10, which I installed via USB ISO on a new HDD. It activated perfectly. So with this install I'm trying out several very old graphics and CAD softwares for compatibility with 10. So far, so good. Now, with surprising success using this old expensive professinal software on 10, I'd like to install another 10 on a somewhat newer machine and new HDD, but not as an ugrade to an existing install of 7 that was activated years ago. I do want to use one of the three keys I paid for years ago. The drive/machine that the key was originally on is long gone and no longer used. Long story I know but what I am wondering is ... what to expect from MS when I try to activate a key that was first used so many years ago??? Any clues how I might go about doing this? Many thanks!

Fresh Install of Win 10 without Serial Key?

Looking to reformat a laptops HDD, and then reinstall Win 10 fresh. The problem is it came pre-installed with Win 8 and I did the free upgrade to Win 10. How exactly would I re-format the HDD, reinstall Win 10 and ensure it reactivates properly? I don't see a Win 8 serial key anywhere in the contents of the box.

 

Win.10 won't boot after installing Win.7

Hi,

So i installed Win.10 via the UEFI and after installing Win.7 on Legacy Mode onto a different HDD i can't boot into Win.10 (I believe can only because Win.10 was installed via UEFI)

I tried installing the BCD Software but nope. I even tried to select my HDD but say Winload.exe error

Even tried going into the USB and try repairing but the same thing happens

 

Is it still possible to find a Win 7 install .ISO?

You managed to work it out: congratz!

I had many issues when i moved to Ryzen 5 and could not get Win 7 to install properly because of USB not being detected but i fixed it ... by removing Win 7 ... permanently ...

Now using Ubuntu.
