I might be wrong, but also the deb.log file in your LFS folder might be of use also, at least i think thats the file that would show if the crash is happening at a certain process of loading
Right click(mouse) the Windows tab/button - then it should be the 3rd option from the top
or
Right click the Windows tab/button - select Run - Type Msconfig and press enter - select the tools tab - then select Event Viewer.
Someone will need to let you know where to go from there to find exactly where the LFS crash would be listed, i would've thought it would be in Windows Logs then Applictations but i'm unable to confirm this
