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 of
each type of boot device (except for optical devices). For example, if the computer is connected
to an optional docking device (select models only) 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.
● The computer will boot from a NIC device only if the device has been enabled in the Built-In
Device Options menu of Computer Setup and if booting from the device has been enabled in the
Boot Options menu of Computer Setup. Booting from a NIC does not affect logical drive
designations because no drive letter is associated with the NIC.
● Drives in an optional docking device (select models only) are treated like external USB devices
in the boot order.
