Windows Reinstalling Query :Computer Question Help!

[CosmicWolf293]

I was wondering, I want to do a clean install on my computer. I have a windows os disk, but I lost the key to it. So I purchased another code. My question is if I use the disk to clean install will the new key work or do I have to download and burn the iso image onto the usb and try that way?

If the key you have matches the OS disk (i.e. the version of windows for both match) - you are good to go.
