Windows 10: Installing Windows 10 from a dead computer to an older, live computer

My Dell T7500 Precision Workstation would not boot and the IT guys said it was a motherboard problem and not worth saving, so we recycled it. However, I kept the hard drive and thought I would install Windows 10 from the T7500 into and even older Dell Precision 670. But nothing I seem to do works. Could it be that the BIOS cannot handle Windows 10. I have tried installing it from the original hard drive and from a flash drive with a recent Windows install copy.

I'm trying to install windows 10 in new computer from USB drive.

My computer had windows 7 already when I bought but question is, will product key right now windows 7 in my computer will work to clean install for windows 10?

My plan is download windows 10 to in my USB and activate product key with windows 7 from my computer for clean install. Will it work?

I repeat, my computer already had windows 7 when I bought computer.

Thanks.

I don't really understand what you're saying.

You have two options:

A) Have a previously licensed version of Windows 7 or 8 on a PC, run the GWX upgrade to Windows 10 (which then swaps your Windows 7/8 key to a Windows 10 license), then do a clean install and Microsoft will automatically license that PC provided the motherboard is installed.

B) Have a Windows 10 license, install Windows 10 on the PC as a clean install, and input that license.
