- TITLE :Err Msg: Windows NT Could Not Start Because of a Computer....
- PRODUCT :Windows NT
- PROD/VER:3.10
- OPER/SYS:WINDOWS
- KEYWORDS:err msg
-
- ----------------------------------------------------------------------
- The information in this article applies to:
-
- - Microsoft Windows NT operating system version 3.1
- - Microsoft Windows NT Advanced Server version 3.1
- ----------------------------------------------------------------------
-
- SYMPTOMS
- ========
-
- When 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.
-
- CAUSE
- =====
-
- When 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 INFORMATION
- ================
-
- For 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:
-
- 1. From the Main group in Program Manager, run Windows NT Setup.
-
- 2. From the Options menu in Windows NT Setup, choose Add/Remove SCSI
- Adapters.
-
- 3. Choose the Add button.
-
- 4. Read the Setup message, and then choose the OK button.
-
- 5. Select the Adaptec 174x adapter.
-
- 6. Enter the appropriate path for the installation media, and then
- choose the Continue button.
-
- Windows NT Setup will install the selected driver.
-
- You will now see a list of the SCSI adapters installed on your
- system. You should see both the Adaptec 154x and 174x SCSI
- adapters.
-
- 7. Highlight the Adaptec 1542c and choose the Remove button. Read
- the Setup message, and then choose the OK button.
-
- The Installed Adapter list will again be displayed. Choose the Close
- button and quit Windows NT Setup.
-
- 8. Open File Manager and allow viewing of Hidden/System Files. Do
- this choosing By File Type from the View menu and then select the
- Show Hidden/System Files check box.
-
- 9. In the root directory, highlight the hidden file NTBOOTDD.SYS.
-
- 10. Rename the file to NTBOOTDD.OLD.
-
- 11. Copy the appropriate driver from the <systemroot>\SYSTEM32\DRIVERS
- directory. In the example, the file for the Adaptec 1742 is
- AHA174X.SYS. Copy this file to the root of drive C.
-
- 12. Rename the file just copied to the root directory (in the example
- it is the file AHA174x.SYS) to NTBOOTDD.SYS and place the Hidden,
- System, and Read Only attributes to the file.
-
- 13. Quit all applications and shut the system down.
-
- You can now replace the Adaptec 1542c adapter with the Adaptec 1742a
- adapter. When you reboot Windows NT, the appropriate drivers will be
- in place to let you use the 1742a adapter as the controller for drive
- C.
