When you try to start Windows NT after you install Windows 2000 on your Windows NT-based computer to set up a dual-boot configuration, you may experience either of the following symptoms:
- You may receive the following STOP error messages:
0x00000050 (0xF745C76E, 0x00000000, 0x00000000) PAGE_FAULT_IN_NONPAGED_AREA

- After you choose to start Windows NT, your computer may restart automatically.
CAUSE
This issue can occur if you are running a third-party Advanced Power Management (APM) program that is started by the Laptop.sys driver file, and the original Ntdetect.com file was replaced before you installed Windows 2000.
RESOLUTION
To resolve this issue, contact the manufacturer of your third-party
APM program to inquire about the availability of a fix for this issue.
To work around this issue, rename the Laptop.sys file, restart Windows NT, and then uninstall or disable your third-party APM program:
- Right-click Start, click Explore, and then locate the Laptop.sys file in the \%Windows%\System32\Drivers folder where %Windows% is the folder where Windows NT is installed.
- Rename the Laptop.sys file to Laptop.old, and then restart your computer to Windows NT.
- Uninstall or disable your third-party APM program. For information about how to do so, view the documentation included with your program, or contact the manufacturer of your program.
