   Would something like the BlackDog device be useful?  Plug it into
a USB port on the laptop, have it load the cluster...  You would
probably still need the install image(s) on the Windows laptop as
BlackDog only holds 256/512 MB flash memory.  But from the description
at http://www.projectblackdog.com/product.html it doesn't sound too
intrusive to your Windows system, depending on how you set it up.
