Looks like the SSD is not being detected. Try doing a power cycle of the SSD. The following steps should be carried out and take ~1 hour to complete.
- Power off the system.
- Remove all power supplies (ac adapter then battery for laptop, ac adapter for desktop)
- Hold down the power button for 30 seconds to close the circuit and drain all components of power.
- Reconnect all power supplies (battery then ac adapter for laptop, ac adapter for desktop)
- Turn on the system and enter the BIOS (see your manual for the steps to enter the BIOS)
- Let the computer remain in the BIOS for 20 minutes.
- Follow steps 1-3 and physically remove the SSD from the system by disconnecting the cables for a desktop or disconnecting the drive from the junction for a laptop.
- Leave the drive disconnected for 30 seconds to let all power drain from it.
- Replace the drive connection(s) and then do steps 4-8 again.
- Repeat steps 1-4.
- Start your computer normally and run Windows.

While that may not be your drive, a power cycle should be the same on all SSD drives. See how the system responds after the SSD power cycle.
