MultiBoot Default Boot Sequence By default, when more than one bootable device is 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 primary 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) can boot either as drive A or drive C, depending on the format of the disc. Most bootable discs boot as drive A. If you have a disc that boots as drive C, the system will boot the diskette drive before it boots the disc. 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. B-2 Hardware and Software Guide
