Setting up Windows on an existing hard drive that's already running another OS
Setting up Windows on an existing hard drive that's already running another OS
You should prepare your WD Black 1TB by cleaning the HDD and ensuring all video files are ready. Installing Windows 8 may require a full cleanup before proceeding.
You can retain the files but it's best to start with a thorough clean. Place them on a flash drive or back them up in the cloud before wiping the drive and installing.
If they're on another partition besides the Windows one, then it's possible. You can simply change the layout of your C drive and set up Windows there. It won't affect any other partitions.
