The bios will get information from the partition table. For example, you 
can set the active partition on  hda1,hda2 or hda3 on my setup. They are 
primary partitions. The active partition is marked with an * for the 
active partition using fdisk (linux version).

You can't boot from hda4 (extended container) or from hda5 (partition in 
an extended partition, BIOS is not smart enough to do this.) So you 
should be able to boot from any partition that you install grub in, as 
long as it is a primary partition.

Why I have an extended partition that is all used up by linux swap is a 
bit worthless, but that is the way the installer set it up.

You can set the active partition using the fdisk for windows also. I 
believe it uses "A" to denote which is the active partition.
