Win7 doesn't accept product key after reinstall from Win10

Specs: Windows 7, Intel Core i3-4005U CPU @ 1.70GHz
Coming from Belgium I expected internet connection problems with the Huawei dongle that is used in Ethiopia on my upgraded Win 10 laptop so I copied my original Win 7 Home installation disc with the product key from the DVD box.

Sure enough the dongle was not recognised and the software on it did not even load. The computershop tried but did not succeed and advised to go back to windows 7. Using the feature to start from a DVD I installed Windows 7 but when asked for the product key it does not accept it.

Maybe some history is necessary to solve the problem. The laptop a Lenovo G50 came with 8.1 installed, but soon after buying it I was lured into the upgrade to Win 10. In neither OSs I could get on, being a longtime Win 7 user. I decided to install Win 7 upgrade, as I still had one of the three licences available. I formatted all discs and tried to install, but did not succeed, my computershop fixed it. (I should have started from Vista they said).

Then decided to take the risk and just before my extended stay in Ethiopia to do what Microsoft suggested and again updated to Win 10.

Now I am left with a laptop that asks for a valid product key and keeps asking so after a restart. Booting from another DVD is not possible, I would have put Ubuntu on it !!! What are the possibilities ?

Your laptop should have its original Windows 8 product key on a sticker, usually under the battery. That should let you reinstall Windows 8 and then upgrade if Windows 10 does not accept it directly. Note you will need to install from an OEM disk rather than a retail disk though. If necessary, Lenovo should allow you to purchase a set of factory restore disks for the machine at a reduced price with your serial number and possibly proof of purchase or prior registration of the machine.

You have to be a little bit crazy to keep you from going insane.

The windows 8 computers don't come with a product key sticker. You have to use rweverything to read the win8 key off the motherboard. You can install windows 7 with out using a key to get a working OS to run rweverything, or you can run it in a preinstall environment.

A complicating factor is that in Ethiopia the usual internet connection uses a Huawey "dongle". So when I want to re-install Win 7 again, there is no internet connection during the installation procedure and that is probably the reason that the installation could not verify the product key.

Have at the moment found a (temporary) solution as I still had an old Vista version on DVD here in Addis. Using the F8 key at startup it was possible to boot from this DVD and the installation apparently accepted its product key.

Have looked for the product key with rw everything, but this program did not find a product key with that, probably because of the previous reformat of all partitions when Win 7 was first installed. Nowhere on the laptop was a product key to be found.

With windows 7 you don't have to install a key to install the OS, you can just leave the key blank and continue the install. But if it doesn't accept your key in the install it won't take the key after the install. I think the problem is that you are using the wrong installation media for the key that you have. Anyway rweverything never fails me on windows 8 computers when I extract the key. Take a look here and see if you can get the win 8 key

Unfortunately I do not have all the right DVDs that could solve my problem. I was sure that my new laptop was a 64bit version, but apparently it is not, so the copy of my win7 is 64bit. At the moment I have Vista on the machine and that works sufficiently to bridge the time before I get home. Thanks everybody for now.
