Windows 10: Windows 10 Upgrade for corrupt Windows 7

I have an HP desktop I believe the hard drive is failing. It will not boot, I get all kinds of startup errors.
I tried a bunch of things (chk dsk let it run forever etc) to fix that no success. I was able to backup the drive.
Windows 10 had been downloaded but not installed. I want to just replace the hard drive and load windows 10.
Is there a way I can download the iso for windows 10 and use my Product Key from windows 7? I have my product key.

Thanks

:)

 

Windows 10 update failed due to corrupt windows 7 files

I had a Windows 7 Home laptop Lenovo Z575 that was completely corrupted by the Windows 10 upgrade, it won't even boot. When I use the Windows 10 USB install stick I created, it wants a new license key for Windows 10, it doesn't let me use the Windows
7 license key and treat it as an upgrade even though it really has to be a new install because it is completely corrupted. Do I really have to purchase a Windows 10 License even though I had a valid Windows 7 license key, Microsoft.com doesn't let me download
a new Windows 7 ISO file because it says the license key is bundled with the manufacturer, Lenovo recovery isn't an option because the recovery partition was corrupted by the Windows 10 upgrade.

 

Windows 10

I have upgraded to windows 10 pro from a 7 pro upgrade. The original computer was vista business. When I upgrade to windows 10 the product key gives me an invalid product key. I type in the windows 7 pro key (upgrade version) and it will not accept
it. Revert to windows 7 pro and everything is fine. Fix corrupt files from restoring windows 7, upgrade to 10 pro and no activation. Can you upgrade from windows 7 pro upgrade to windows 10 pro, or do you leave it at windows pro 7?

 

Yes. Just install the matching edition and version of Windows 10 that the Windows 7 product key is for. Click "I don't have a product key" when first asked. Click "skip" or "do this later" when asked for the product key until Windows 10 is fully installed. Then go to settings, updates and security, activation and change product key, enter the Windows 7 product key to activate it.

 

2 official sites to download Windows 10 ISO file.

Media Creation Tool
https://www.microsoft.com/en-au/soft...load/windows10

Tech Bench
https://www.microsoft.com/en-US/soft...load/techbench

I would recommend that you use Tech Bench link.

RE : Is there a way I can download the iso for windows 10 and use my Product Key from windows 7?

Yes, you can install Windows 10 with the downloaded iso file and activate it with your Win 7 product key.

There are 2 ways to install Windows 10 using the iso file :

1. In-place upgrade install.

In-place upgrade install allows you to keep your files, settings and apps.

2. Clean Install

Clean Install will NOT let you keep anything. You start fresh.

 

Awesome thanks everyone!
