[CentOS] Reinstall Windows but preserve CentOS

[Dan Pritts]

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?
