No Superdrive or External USB drive... How to installing XP?

[theaero]

So, i've been trying to figure out a method to do this for quite sometime. I have a slipstreamed version of XP I'd like to install, but all I have at my disposal are an external hard drive, and a USB drive. I'd prefer not to use refit or parallels. Is there a way to restore the XP image I have onto the external, and install from that?

Thanks.

I think you may be out of luck assuming you are talking about bootcamp.
I believe it requires a genuine Windows install CD.

No, I've used slipstreamed CDs before with no issues. Another idea is, can I install windows XP on the external drive using another computer (Windows machine) then disconnect it, and use it with my MBP?

I found this guide on how to install Windows 7 on a MacBook Air (or Pro).

Would the same thing work work with XP?
