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.
NOTE:
If you are booting to a USB floppy drive, you must first set the floppy drive to OFF in system setup (see
"System Setup" on page 107).
1 If you are booting to a USB device, connect the USB device to a USB connector (see "Connectors" on
page 105).
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 (see "Turning Off Your Computer" on
page 59) 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>.
NOTE:
To boot to a USB device, the device must be bootable. To make sure your device is bootable, check the
device documentation.
