Hello, I have a Dell OptiPlex 7050 Micro and would like to install the Intel 660p as the boot drive. Windows 10 is already installed on another SSD (2.5”) that it came with. When I plug in the M.2 drive it doesn’t appear to be recognized in Windows or in the BIOS except as an empty drive identified only by its controller (SM2263). I was looking up help online that said to use Windows Media Creation Tool to create a bootable flash drive with Win10 installation, which I did.  However it doesn’t seem to properly detect the drive during the installing process and lists it as a drive with less than a gig of space, not enough for Windows to install to. I have tried setting boot to UEFI and SATA to AHCI as others have suggested. No luck. 

The drive does not even show up in Windows when running the other SSD. I have tried looking for Intel drivers but don’t understand what I’m supposed to use. I did try loading drivers from Intel off the USB stick when attempting fresh install of Win10 but nothing happened. 

Also I tried flashing the BIOS and making sure I have updated drivers in general through Dell’s website. 

Any help would be appreciated.
