I had the problem "boot device not found" and the following was the solution .. the power cable was not correctly connected to the power supply .. the thin client still had voltage because it was shown graphically that the hard disk is not recognized .. after the plugthe power supply (230VAC side) has rebooted and the thin client is working properly again .. I tried that with another thin client, it didn't happen, but when I used the power supply with the first onehad not booted, the same thing happens again on another thin client .. I think the power supply is defective.
