I have had problems in the past with having GRUB try to manage booting more than two O.Ss. Is there a cheap and easy way to make a copy of the MBR on paper and just input sector address or what ever if GRUB fails,make a copy of the MBR first of course. I have a recovery disk but I don't want to get overly involved unless GRUB fails. I studied this extensively at one time but could not get a really clear overview so I should at least know most of the terms.

Thanks in advance!
