Operation system not found

ok so u need a passowrd to accsess the bios, not good if u dont have the password , just a quick note you dont have a floppy or cd inserted ? that can cause this problem , the laptop may have been bumbed alittle to hard and damaged the hard drive , can also be caused from not shutting the laptop down properly , you may need to reinstall xp , you can also try removing the hard drive and putting it back in nice and secure , the hard drive slot will be located at the bottom of the laptop or on the side,

I had to use the recovery console on the xp disk to run "fixmbr" to fix my corrupted master boot record. the mbr is the file that tells the computer where the rest of the instructions are. without the mbr, it doesn't know where to go for the next instruction, which would be from your operating system.

there is another option which fixes faulty bootup instructions.

hope that helps.
