You should be fine. There maybe some issues, but if it gets to complicated you can always reformat and start fresh (assuming you have a windows cd).
Worse case scenario it doesn't work period.
Second install windows from a cd because it won't load.
Best case you pop it in it loads straight away without much of a hassle other then installing new drivers to get certain things to work (sound, video, network).
Either way it won't hurt to try, it' shouldn't damage any of the other laptops hardware.
Thank you so much for the quality response, i really appreciate it.
