this looks nasty. on bootup i get an error saying something like "windows could not start becos the following file is missing or corrupt: wondows/system32/config/system you can attempt to repair this file by starting windows setup using the original setup CD ROM. select "r" at the first screen to start repair." i press R and it just restarts.. and pressing any other button also restarts comp. I cant go any further than this screen (am on a laptop now). Problem is i dont have the Windows xP professional CD.. is there any other way to tackle this prob?? i need help asap. i cant even enter safe mode (although i can reach the safe mode menu). At the time i was chatting on msn and my pc randomly restarted and this happened.
