Boot Sequence

This feature allows you to change the boot sequence for devices.

Boot Options

•USB Floppy — The computer attempts to boot from the USB floppy disk drive. If no operating system is on the floppy disk, the computer generates an error message.

•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.

•CD/DVD/CD-RW Drive — The computer attempts to boot from the CD/DVD/CD-RW drive. If no CD/DVD/CD-RW is in the drive, or if the CD/DVD/CD-RW has no operating system, the computer generates an error message.

•USB Storage Device — Insert the memory device into a USB connector and restart the computer. When F12 Boot Options appears in the lower-right corner of the screen, press <F12>. The BIOS detects the device and adds the USB flash option to the boot menu.
