Put a disc in the unit and reboot.
Enter the bios.....does it show in the boot order?
You might need to get an usb Y cable to make this function.
I've just been told by HP tech support that the HP Elite x 2 1012 G2 cannot support a bootable external DVD optical drive.
An external drive can be accessed via Windows Explorer for file copying etc but the machine can't boot from bootable DVD media.
The reason they gave is that the USB 3.0 port cannot deliver enough current to power the drive and the BIOS won't register the drive ID in the list of boot devices when F9 is pressed.
I find this puzzling especially since the instructions for booting from an "optical drive or USB flash drive" are clearly stated in the User Guide (p.60) and HP supply a Windows OS boot DVD in the box!
I know I can boot from a bootable USB flash drive but am anxious to know if the inability to use bootable DVD media is a defect or a design decision. If it's a design decision, this would be the first PC I've ever owned or used that can't boot from DVD media.
Has anyone one else come across this?
