The diffference between the two is not always that clear. grub can also be seen as a boot manager.

Actually I have xosl residing on a small primary partition about 16k, smallest possible on a 2TB hard disk.
I found this to be perfect in the days of the OS/2 boot manager so I am keeping the same approach with a newer bootloader.
I would use the OS/2 bootloader but it doesn't support newer hard disks.

The idea is that if the MBR is damaged by a linux distribution or OS/2.  I just boot on a floppy and restore the MBR.
Nothing special is needed for the MBR, I just have to set the bootloader partition as active.
