STOP: 0x000007E: Inaccessible Boot Device SCSI controller that fails to adhere completely to the SCSI standard is installed in a Windows NT machine. It can also occur if you add a SCSI controller to an NT machine that boots from an IDE hard disk. In that case, make sure no SCSI device is set to SCSI ID 0; otherwise, disable booting from the SCSI drive(s). This prevents the SCSI controller from attempting to boot the disk and stops NTDETECT.COM from assigning the SCSI adapter a bus number equal to zero, which might cause BOOT.INI to point to the wrong partition.�
