Install WinXP from USB Drive

Hey guys,

I've this big problem. My laptop's DVD-ROM is out of order and my laptop has been attacked by Brontok virus and has made it extremely slow...

I want to format and reinstall Windows XP, so tell me whether there is any method to do so.

I mean can I make an exact replica of Windows XP bootable CD on my Pen Drive and then install it.

I hope no Piracy issues here, coz I have my own WinXP CD and just want to use it otherwise.

Please help coz I really need to do it soon!!!

Thx in advance!!!
