MultiBoot Default Boot Sequence By default, when more than one boot device is installed in the system, the notebook chooses the startup device by searching enabled devices and locations in a predetermined sequence. On every boot, the system looks for bootable drive A devices first. If it fails to find a bootable drive A device, it searches for bootable drive C devices. Drive A devices include optical drives and diskette drives. Drive C devices include optical drives and primary hard drives. The hard drive can only boot as drive C. The NIC does not have a drive letter assigned to it. ✎ An optical drive device (such as a CD-ROM) can boot either as drive A or drive C, depending on the format of the CD. Most bootable CDs boot as drive A. If you have a CD that boots as the C drive, the system will boot the diskette drive before it boots the CD. By default, the notebook selects the startup device by searching enabled devices and locations in a predetermined sequence. You can change the sequence in which the notebook searches for a startup device by enabling MultiBoot and entering a new startup sequence, also called a boot order. Or, you can use MultiBoot Express to set the notebook to prompt you for a startup location each time the notebook is started or restarted. 8-2 Hardware and Software Guide
