Yes.

Check the hide and unhide commands.

It would be something as this:

title Boot 1
unhide (hd0,0)
hide (hd0,1)
rootnoverify (hd0,0)
chainloader +1
boot

title Boot 2
unhide (hd0,1)
hide (hd0,0)
rootnoverify (hd0,1)
chainloader +1
boot


The problem with some xps is that even if you do this trick they 
remember the partitions that were before the hiding.
I think there's a solution about editing I don't know what about the 
registry.

Or... if you do not mind working... you hide the 2nd windows.
You install the 1st windows. You hide the 1st windows.
And then you install the 2nd windows. Then... you use these commands
from grub console and you're done.


If you do not mind reinstall Windows you can recover your grub with my 
Super Grub Disk (http://adrian15.raulete.net/grub/)

You can also use Super Grub Disk to hide and unhide partitions and boot 
whatever you want to (in theory, I haven't tried it myself in a real 
system).

The option is found inside the Special Boot menu. Hide and Unhide and... 
boot option I think it is called.
