I have a computer that was built with Windows 7
It upgraded itself about a month ago to Windows 10
Now I am getting a hard drive error and it looks like the hard drive has failed.
So if I get a new Hard drive should I install Windows 7 or Windows 10?
I have the Key for Windows 7
as well disk for both Windows 7 ,10?

Activating after reinstalling Windows 10
How you activate Windows 10 after reinstalling it depends on how Windows 10 was originally installed on your device.
If you activated a free upgrade to Windows 10 or bought and activated Windows 10 from the Windows Store, you have a digital entitlement for your device. This means you can reinstall the same edition of Windows 10 that your device has a digital entitlement for without entering a product key. During reinstallation, if you’re asked to enter a product key, select Skip. Windows 10 will automatically activate online after the installation is complete.
If you previously installed and activated Windows 10 using a product key, you’ll need to enter the product key during reinstallation.
Before you reinstall Windows 10 make sure that your current version of Windows is activated. Select the Start button, then select Settings > Update & security > Activation. If Windows 10 isn’t activated on your device, see Get help with Windows 10 activation errors for more info.
For more info about how to create installation media for Windows 10, go to the Microsoft software download website. When creating installation media, make sure to choose the edition of Windows 10 that matches the edition that’s already installed on your device.
You don't have to start again with Windows 7 if you have an ISO.
To obtain an ISO.
Hope this answers your question.
