3.Select the order of the devices from which BIOS attempts to boot the operating system
If BIOS is not successful at booting from one device, it tries to boot from the next device on the list.
If there is more than one device of the same type, e.g. several hard disks, the displayed entry represents the first of these devices as specified in the boot configuration via setup.
The same options determine the order in which POST installs the devices and the operating system assigns device letters. BIOS supports up to two floppy devices to which the operating system may assign, e.g. drive letters A: and B:. The drives C:, D:, E: etc. are reserved for hard−disk drives.
Note:aThere is not always an exact correspondence between the order specified in setup and the letters assigned by the operating system. Many devices, such as legacy option ROMs, support more than one device that can be assigned to several letters. If the CD−ROM drive should have a letter coming before the one assigned to the hard drive, move it in front of the hard drive. The group of bootable add−in cards refers to devices with non−multiboot−compliant BIOS option ROM from which you can boot the operating system.a

To enter the boot menu, press <ESC> during POST. The menu that appears looks similar to the one shown in the following figure. Note that the layout may vary slightly with new BIOS versions.a
