Well I think you have to use the Windows CD to restore the boot partition for the Windows boot.
Windows "likes" sitting in the first partition therfore you can't move it to anywhere else.
Here is a step-by-step guide to restore the boot on Windows: http://www.howtogeek.com/howto/32523...ader-problems/
After you restored it then the Linux wont boot. So you will need to update the grub on the Linux box too.
If the Linux installed on the first disk you can run this command:
# grub-install /dev/hda
It will install the grub boot loader into /dev/sda master boot record then you will be able to boot into Windows and Linux too.
