Any idea what happens if you make a back-up or ISO and then later swap out the hard drive? Shouldn't I be able to just load the ISO onto a new hard drive that is partitioned to the same size?
It kind of annoys/scares me to think I may need to replace a drive on an otherwise perfectly capable computer and then pony-up for a Windows license. Maybe I should save those old Win7 ISO backups?
I'm not 100% clear on the question but if you were talking about making an ISO of the Windows 10 and installing it again on another drive that shouldn't be an issue. You also shouldn't need to partition anything with the clean install. Chaning out a drive is not going to require any KEY, only multiple components or an integrated motherboard.
