Building a BDD/Microsoft Deployment USB Boot drive from XP

In my earlier post about using Microsoft Deployment off a USB drive I gave instructions for using the Diskpart tool to format, partition and set the USB drive as active.  Turns out that only works under Vista.  Under XP, when you do a “list disk” in diskpart it can’t even see the drive.  So…as a work around here is what we did.  First off I’m using a SAN cruzer 8GB stick but they are all about the same.  First I uninstall the U3 autoloading nonsense.  This will end up reformatting the drive which is just fine. The I use a copy of bootsect.exe from the WAIK kit (installed under c:\Program Files\Windows AIK\Tools\PETools\x86) and I run:

bootsect /nt60 f:

Then I copy the contents of the .iso created from the Microsoft Deployment point (the media one) onto the drive.  From here it boots and all is well.
