Boot Sequence
This feature allows you to change the boot sequence for devices.
Option Settings
l Diskette Drive — The computer attempts to boot from the floppy drive. If the floppy disk in the drive is not bootable, if no floppy disk is in the drive, or if
there is no floppy drive installed in the computer, the computer generates an error message.
l Hard Drive — The computer attempts to boot from the primary hard drive. If no operating system is on the drive, the computer generates an error
message.
l CD Drive — The computer attempts to boot from the CD drive. If no CD is in the drive, or if the CD has no operating system, the computer generates an
error message.
l USB Flash Device — Insert the memory device into a USB port and restart the computer. When F12 = Boot Menu appears in the upper-right corner of
the screen, press <F12>. The BIOS detects the device and adds the USB flash option to the boot menu.
Changing Boot Sequence for the Current Boot
You can use this feature, for example, to restart your computer to a USB device such as a floppy drive, memory key, or CD-RW drive.
1. If you are booting to a USB device, connect the USB device to a USB connector (see " Front View of the Computer " and " Back View of the Computer ").
2. Turn on (or restart) your computer.
3. When F2 = Setup, F12 = Boot Menu appears in the upper-right corner of the screen, press <F12>.
If you wait too long and the operating system logo appears, continue to wait until you see the Microsoft Windows desktop. Then shut down your
computer and try again.
The Boot Device Menu appears, listing all available boot devices. Each device has a number next to it.
4. At the bottom of the menu, enter the number of the device that is to be used for the current boot only.
For example, if you are booting to a USB memory key, highlight USB Flash Device and press <Enter>.
