Well what concerns me is that I can reproduce this all I want. Try to uninstall LiteStep or change the shell and... NTLDR is gone, as well as NTDETECT.com and Boot.ini.

I went into Safe Mode to uninstall LS since in normal mode under my account it told me I didn't have proper priviliges. Then in safe mode, under the Administrator account, it again told me I didn't have the rights to uninstall.

I just went an manually changed the shell with regedit and now I'm back to explorer and everything's fine.

Maybe this problem is totally unrelated to LS, but it is a bit strange that it does this everytime I try to use LS.
