Long story short I had a disc come with a new system that I purchased recently. I removed the original drive and installed a black Samsung SSD drive and figures since the PC came with the Dell OEM Windows 10 disc I could install it directly from there instead of installing Window 7, then upgrading to 10 using the media creation tool. My problem was that the setup would not start. I forget the exact error but it said something along the lines of missing partition required for install I've never had that problem with previous Windows version. Shouldn't I be able to clean install directly from the disc?
