Fail to prepare or prepare to fail- backing up your Master Boot Record (MBR)

Backup, like security, is a well-worn mantra in the world of GNU/Linux—and even the most battle-hardened, street-wise user has, for whatever reason, thought about regular backups after disaster has already struck. It is an all too familiar story. System Administrators, by the very nature of their work, will have that imperative carved on their headstones. For them it will be a way of life. Desktop users, being responsible only for themselves, can afford to be a little more louche about such things. If it all goes a bit “arms in the air” there is no one to reproach them but themselves.

You should backup many things: the files in your home directory, configurations files in /etc, (and there are many excellent graphical tools to do the job) but one of the simplest and best things you can do is to backup your boot master boot record (MBR). It’s one thing to experience lost or corrupted files, it’s quite another not to be able to bootup your computer at all. What follows may just get you out of a fix.
