How to boot Windows XP from USB flash drive

This stuff is not exactly new, but nevertheless quite useful, as it appears that there are lots of contradictory and quite complex guides on the subject.

The truth is that it is quite simple to make bootable WinXP USB drive (at least it worked like a charm for me and it would be interesting to learn about other people's experiences on different hardware).

Prerequisite:

• BartPE builder
  
• PeToUSB
  
• Windows XP installation CD
  

Instructions:

• Download and install BartPE bulder and PeToUSB
  
• Run BartPE, follow the instructions to create Windows PE installation
  
• Run PeToUSB, follow the instructions to format the USB drive and copy Windows PE files
  

That's it!
