0) make a backup. 1) unplug the centos drive while you do the install, just to be sure. (warning, you may run into master-slave complications due to this, depending how you've got things configured) 2) install windows. 3) boot from centos disk in rescue mode. re-install grub. I think the right syntax for this would be: chroot /mnt/sysimage /sbin/grub-install 4) you did remember to make a backup, right?
