Description Of Issue
The subject says all that needs be said. NUC seems soft-bricked.
Hey @Tim_Pointon,
Do you have an ability to hook your NUC to monitor via HDMI cable and check what is being printed on the screen.
Also, it would help us to continue troubleshooting if you could describe specs of your Nuc ( including SSD make / model) and your BIOS version ?
Thanks
