Most of the time you can get windows to boot up in local safe mode with command prompt or if necessary use a Windows 7 install or recovery CD thats been made to get to the prompt. Then you can run things like system file checker which usually has a pretty good success rate and fixing issues well enough to get you into the GUI interface of SAFE MODE and get a foot hold at starting to run your kit removals

You can also use the program that MS posted like HitmanPro Kickstarter and load up via a USB stick....its basically the same type of principal. Which is basically just loading up a minimal/selective startup version of windows....basically same thing as safe mode...
