So I am building a brand new pc and I have a hard drive with windows 10 oem installed. I know I can't use it and use the same windows 10 on the new pc which replaces all parts except for the hard drive. How am I able to keep all my files and reinstall a new copy of windows 10 on it without any problems? Explain the steps to installing windows 10 to the old hard drive when I first boot up the new PC. Thanks!
