If there's a bad hardware driver that is causing Windows to crash during startup, how can you update the driver? Do I need to make a boot disk?

I have the driver installation disc that came with it and tried to boot from it; obviously that didn't work. Is there a way to do this? I'm not sure if it's indeed a bad hardware driver that's causing the crash, but I'm getting a BSOD with a DRIVER_IRQL_NOT_LESS_OR_EQUAL - among other things I want to try updating the drivers, but I can't get into Windows to do it the normal way.

There is a Windows boot disc called "ERD Commander" 5.0 (XP), it is not publicly available but can be found, you can boot from this disc and disable startup drivers with one of the admin tools, then you can get it booting again. version 6.0 is for Vista and 6.1 is for Windows 7 –  Moab Aug 29 '11 at 14:52

Unfortunately, you may not be able to use this tool unless you have a license with SA from Microsoft, but, if you do (or have MSDN/Technet), the best tool for this is MS-DART (The Microsoft Diagnostic and Recovery Toolkit)

This is the updated version of the old ERD Commander, and it allows you to make a lot of changes to the installed Windows on a system, including drivers.

ERD Commander... Was a great tool. Used it a lot in the past for XP. –  SgtOJ Aug 29 '11 at 16:54

even in safe mode, it gets just past the "hey you're in safe mode" dialog box before it crashes. so any kind of in-windows solution is out. –  Marty Aug 29 '11 at 2:31
    
Have you tried restoring to past restore point? By default Windows creates one before updating driver and installing programs. –  SgtOJ Aug 29 '11 at 2:35

+1: There are two options. A Roll Back Driver option and a Last Known Good Configuration option. –  surfasb Aug 29 '11 at 9:38

You want to boot to safe mode so that Windows doesnt load the faulty driver (if that is the issue)

Here is a good write up on how to boot into safe mode and how to use the device manager to update drivers.
