Can i change address of Master Boot Record

[Saurabh Jain]

Hello every one !

I was reading the booting process of Linux kernel. I got to know that
generally the location of MBR is first sector of the bootable device. I
want to know that whether we can change the location (Starting address ) of
Master Boot Record or not . Can we do this for Linux and Windows both.

Hint: What piece of software loads the MBR from the disk?  And who wrote
that software, and what would it take to get them to change it?

For what reason do you want to change it?

As far as I understand, you can leave the beginning (first 512 bytes -
partition table) of your MBR empty (NULL). Then, the BIOS will look into
your partition table for a partition with enabled boot flag. If present
it will look there for a boot loader.

I don't know if this is something you were looking for. Anyways, you
will not be able to change the location of your MBR unless your BIOS
explicitly supports that, but I never heard of such options.
