Enabling boot devices in Computer Setup

The computer will boot to a USB device or a NIC device only if the device has first been enabled in Computer Setup.

To start Computer Setup and enable a USB device or a NIC device as a boot device, follow these steps:

1.Turn on or restart the computer, and then press esc while the “Press the ESC key for Startup Menu” message is displayed at the bottom of the screen.

2.Press f10 to enter Computer Setup.

3.To enable bootable media in USB drives or in drives inserted into an optional docking device (select models only), use a pointing device or the arrow keys to select System Configuration > Device Configurations. Confirm USB legacy support is selected.

NOTE: The USB Port option must be enabled in order to use USB legacy support. It is enabled at the factory. If the port becomes disabled, reenable it by selecting System Configuration > Port Options, and then selecting USB Port.

To enable a NIC device, select System Configuration > Boot Options, and then select PXE Internal NIC boot.

Considering boot order changes

Before changing the boot order, note the following considerations:

●When the computer restarts after the boot order has been changed, the computer attempts to start using the new boot order.

●If there is more than one type of boot device, the computer attempts to boot using the first device of each type of boot device (except for optical devices). For example, if the computer is connected to an optional docking device that contains a hard drive, this hard drive will be shown in the boot order as a USB hard drive. If the system attempts to boot from this USB hard drive and fails, it will not attempt to boot to the hard drive in the hard drive bay. Instead, it will try to boot to the next type of device in the boot order. However, if there are two optical devices, and the first optical device does not boot (either because it does not contain media or the media is not a boot disc), the system will try to boot to the second optical device.

●Changing the boot order also changes the logical drive designations. For example, if you start up from a CD-ROM drive with a disc formatted as drive C, that CD-ROM drive becomes drive C and the hard drive in the hard drive bay becomes drive D.
