after I installed McCafee on my computer and shut it down, it would not let me log in to Windows xp professional.I tried to start in safe mode, etc, boot from cd , but it just goes to loading settings and then logs me out before even opening to my settings. Can Anyone help?
Try booting windows through "Last Know Good Configuration", Press and hold F8 while switching on your PC & select the option "Last Know Good Configuration". If the windows loads successfully please check for 3rd party incompatible applications & remove them if you find any, you can look for it under Add/Remove programs. For Example : Norton, AVG...etc.
