If you have installed a new driver or application and Windows won't boot, try roll back driver first, but if that doesn't work then go to last known good configuration

Last Known Good Configuration (LKGC)
The Last Known Good Configuration feature is a recovery option that you can use to start your computer by using the most recent settings that worked. The Last Known Good Configuration feature restores registry information and driver settings that were in effect the last time the computer started successfully. Use the Last Known Good Configuration feature when you cannot start Windows XP after you make a change to your computer, or when you suspect that a change that you just made may cause a problem. For example, you can use this feature if you cannot start Windows XP after you install a new driver for your video adapter, or if you installed an incorrect driver and have not yet restarted your computer.When you start your computer by using the Last Known Good Configuration feature, Windows XP restores information in the following registry key: HKEY_LOCAL_MACHINE\System\CurrentControlSet Note Any changes that were made to other registry keys remain.

Question too vague.
To remove a route from the configuration, you can use the 'no' command followed by the route information in the router configuration mode. For example, to remove a static route '192.168.1.0' with subnet mask '255.255.255.0' pointing to next-hop '10.0.0.1', you would use the command 'no ip route 192.168.1.0 255.255.255.0 10.0.0.1'. Make sure to save your configuration afterwards.
