I am getting ready to replace the hard drive in my laptop. It came with windows 7. I do no have the recovery disks. Can I just buy windows 10?
You have 2 ways of doing this:
1. Upgrade to Win 10 now, and then a clean install of Win 10 on the new drive when you get it
2. Discover your existing Win 7 license key. Clean install of Win 10 on the new drive when you get it, activating with your Win 7 license.
Assuming, of course, your system can run Win 10. It probably can.
