Problem:

I sent a u25x on site and the person acting as my eyes and hands used the USB 3.0 ports to hook up the keyboard and mouse.

For some reason this causes the box to not see the hardisk and it won’t boot. It first goes straight to trying to boot from PXE then it will give up and ask you to insert bootable media.

Solution:

Plug the keyboard and mouse into the USB 2.0 ports (not the blue ones).
