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 Diskette Interface to Disabled in system setup
(see "System Setup" on page 97).
1 If you are booting to a USB device, connect the USB device to a USB connector (see "Front View of the
Computer" on page 13).
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.
4 Press <F1> to continue.
The Boot Menu appears, listing all available boot devices.
5 Use the arrow keys to select the appropriate device (for the current boot only).
NOTE:
To boot to a USB device, the device must be bootable. To ensure that a device is bootable, check the device
documentation.
