When i start my HP compaq 610 i got a massage "MBR Error 3" for a short
time, after that the system starts normal. I have windows. I don't know how to fix this error
wasnt real helpfull.
Do you have acronis or perfect disk on the laptop? If so, there may have been an error of sorts during a defrag, which in turn is spitting out this error. Try running the defrag again and see what occurs.
