When I first got the computer I removed the installed M.2 card. I put in a 2TB card and tried to install Windows on it. That's where I had the problem discussed above. I solved the problem by taking the OEM M.2 card and put it in a USB enclosure and connected it to my laptop. I then connected another enclosure with my new blank 2TB card and cloned the OEM card to the 2TB card. I the installed the 2tb card in the DELL and it booted up just fine and has been running without any problems. Thanks to everyone for the advice and suggestions.
When I got to the step where I should be able to select the disk where I want Windows to be installed, there were no disks listed, not even the hard drive. The message was asking for the disk driver. Apparently Windows doesn't include disk drivers for Dell computers? What do I need to do to be able to install Windows? Thanks for your help.
