More than one bootable primary partitions
I have three partitions which I've created in cfdisk and want to write. I have a primary, sda1 with Windows on it, and two logicals, sda5 - my swap partition and sda6 - my Linux partition. I've made both my Linux and my Windows partition bootable.
When I select write to write the changes to the disk, it says that more than one primary partition is marked as bootable and the DOS MBR cannot boot this.
Just wondering if it had actually written the changes and if this mattered? What is DOS MBR?
Thanks very much!

You will find lots of info on the web about MBR, the grub manual is a good place to start.
If you get the same windows boot menu when you restart your computer you have not updated the MBR.

Thanks very much! I just left the Windows partition bootable and the other two as normal logical's. That will work right?
Thanks again very much!

Another top tip is make sure you have a copy of the SuperGrub CD before you start playing with boot menus/parameters. That way you can usually get the OS to boot if things don't quite go to plan.
