I have a Acer E15 573G, and I’ve got Windows 10 Home on a 1TB HDD. I’m thinking of removing the Optical Bay, adding in a 2TB HDD on there, and changing out my 1TB HDD with a 120/240 SSD. So If I remove my working Win10 HDD, how do I get my paid OS onto the SSD? Will a clean install + my old product key work? What will happen to my OS on the 1TB HDD if it does?
