I added an ssd to my desktop that already had a 1tb HDD with Windows 10 installed. I read online to make sure the ssd is where windows boots from the best way is to just unplug the HDD and do a clean install on the ssd. I've begun the install but realized I didn't do anything as far as formatting or wiping the original hdd. What will happen when I plug it back in where they both have an os installed? Also how can I just wipe everything from the HDD? Thanks
