HOW TO: Boot Windows 2000-Based Computers When You Use a Debugger Program

This article describes the commands that you can issue from a kernel debugger so that you can initiate reboots of your computer while it is in Safe mode.

Restart Windows While in Safe Mode

When you remotely debug Windows 2000-based computers, you may want to boot the computer into some variation of Safe mode to observe if the operating system can perform either a boot or a different task. To initiate reboots while your computer is in Safe mode:

1. From the kernel debugger, press CTRL+K to request an initial kernel breakpoint, and then type: .reboot.
2. When the computer restarts, type: .reload, and then type: ed NT!InitSafeBootMode X (use the values 1, 2, or 3 for X). The definitions of these values are:

   Mode                Value
   ----------------------------------
   SAFEBOOT_MINIMAL    1
   SAFEBOOT_NETWORK    2
   SAFEBOOT_DSREPAIR   3 (Windows domain controllers only)
