Err Msg: Windows NT Could Not Start Because of a Computer....Last reviewed: May 12, 1997Article ID: Q106482 |
The information in this article applies to:
SYMPTOMSWhen Windows NT is installed on a system that has a SCSI drive as drive C, it copies the appropriate SCSI driver to the root of drive C as a file called NTBOOTDD.SYS. If the host adapter is changed to a different adapter model or brand, Windows NT will not start (boot) and you will receive the following error message:
Windows NT could not start because of a computer disk hardware configuration problem. Could not read from the selected boot disk. Check boot path and boot hardware. Please check the Windows NT documentation about hardware disk configuration and your hardware reference manuals for additional information. Boot failed.The reason for the boot failure is that the incorrect SCSI driver is being loaded. This can be resolved by copying the appropriate driver to the root directory of drive C and renaming it "NTBOOTDD.SYS" prior to installing the new adapter.
CAUSEWhen Windows NT is installed onto a system that has a SCSI drive as drive C, it copies the appropriate SCSI driver to the root of drive C as a file called NTBOOTDD.SYS. This file has SHR attributes. If the SCSI controller is changed to a different type or brand, the NTBOOTDD.SYS file will not be the correct driver for the new controller. To change controller types, you must install the SCSI adapter through Windows NT Setup, and copy the appropriate driver to the root of drive C as NTBOOTDD.SYS. A detailed explanation follows:
MORE INFORMATIONFor the purpose of explanation, assume that Windows NT is initially installed on a system where the drive C is connected to an Adaptec 1542c. Now attempt to change the 1542c to an Adaptec 1742a controller. To do this, do the following BEFORE physically installing the new adapter:
