Unload a device-Collection of common programming errors

I made a device driver. But my system crashed at the moment when it was deleting the device object. I think the symbolic link was deleted and it crashed after it was trying to delete the device as I can’t see the symbolic link in the Global. How do I delete this device now. It also gives me a error popup(system cannot find the file specified Device\Mydriver) when I try to open the listed Mydriver under devices from Winobj.

I tried starting the driver’s service again. I do get a handle back when opening the service. But it wont start now. giving the error value of Cannot find the file specified. I was working fine, i mean starting the driver before this crash.

I am a beginner with drivers and doing this to learn, please guide.

1. Use the interactive boot option and don’t load the troublesome driver. Then you can experiment perhaps by adding diagnostic instrumentation to the driver or other debugging techniques to determine the underlying problem.
