what bootloader are you using? if you want, you can write your master boot record to only boot from your windows partition, so long as you have windows installed already.
to do this, you make a dos bootdisk (you need to go into 'add/remove programs' in the control panel to do this for some reason, not sure if you can do this with winP, i heard something about it not being an option anymore...) anyway, once you have a dos startup disk, and you could download one i suppose, try bootdisk.com i think has a few, if you can't get windows to make one...
Anyway, once you have that disk, boot from it by atsrting your machine with the floppy in the drive, having made sure that your BIOS knows to look for an OS on the floppy before it looks on the hard drive, then once you see a DOS prompt, type 'fdisk /mbr' and bingo, you get one boring windows only type master boot record. You can now do all the drive changing and reinstalling of things that you like.
Hope this is what you were after...
