The order of events were:
- Upgrade the OS
- Laptop requires a restart
- Driver PNP Watchdog Error
- Laptop tries to run auto-repair
- PNP Error Again
- Steps 2-5 loop around
- Tried to reinstall Windows using the MCT (loaded on to a USB drive)
- No drives found
- Try to install the drivers
- Process starts, then after about 5 minutes....
- Get either a Driver PNP Watchdog error, or an inaccessible boot device error (see below)
- Ensured the SSD is seated properly in the device. It is, and the drives are recognized correctly in the BIOS
This is as far as I get. Absolutely no rush & thanks in advance.
