WinXP Install from USB Flash Drive…

My Q: is can I extract an ISO of WinXP to a Flash Drive instead of burning it to a DVD-R… the reason being is that I have a Netbook and currently don?t have an external DVD-RW Drive…so I have no other option and by the way this is the way I installed Win7 Ultimate on my Netbook, so it should work with XP as well right?? I?m creating a new partition just for XP so I can have a dual OS system…
