Greetings,
Welcome to the forum.
I am not a HP employee.
You are having a problem with a 2.5 inch SATA SSD. Have you verified the SSD works in a different PC?
I have seen this problem with certain HP Consumer PCs in this forum before . No solution was offered.
A SATA SSD should work if a SATA HDD works. Try a 2.5 inch HP SSD.
Try this BIOS update for your MB (Link).
Or reset the current BIOS to defaults. Or remove the MB CR2032 battery. Let the PC sit for a while.
Reinstall the MB battery.
Try the current SSD again.
Regards
