I am here trying to tweak system file checker. My system is having a problem. It is giving me a serious dll problem on boot. Now when I run System File Checker it will ask for the windows installation disc which I do not have. So I am looking for some option by which I can simply modify the path of windows registry. I just want to provide the location of root folder that is on my pc. The i386 folder lies in the root of my system and I am looking for some option by which I can simply modify the path and and tell system checker to use the root folder in my pc.
