Windows 10 new install won't recognize the SSD

The computer is an HP Desktop with the original HDD removed. The SSD us a new drive, installed in the computer. Am trying to install Windows 10, but it won’t see the drive. The drive shows up correctly in the BIOS. Attached the SSD to another W10 machine via USB, and created 1 simple partition and formatted it. W10 install still does not see the drive. W10 wants a signed driver. Do I need one? If so, where can I get one? If not, how to proceed?
