Spamcram, If your fortunate enough to have a licensing agreement that permits use of WinPE, it will be available to you. However, you have to log in to the licensing site and request it, MS does not send it automatically with your regular shipment of CD's. This product is typically only available to OEM's and very large IT shops. WinPE is the new preferred 32-bit pre-installation environment (i.e. they want you to use this instead of the old MS-DOS network client 3.1). Fear not, there is an alternative which may help you, that's Bart's PE. I have included the link below. http://www.nu2.nu/pebuilder/ This isn't an MS product but accomplishes alot of the same things that WinPE does. I've also read somewhere where it may be possible to add BartPE as a RIS menu option. There are a few lowcost add-ons to RIS that would allow you to do just that. Here is one; http://www.emboot.com/products_risme.htm The following site has also proven invaluable to me when automating builds as well. http://unattended.msfn.org Hope this helps Bigjoe P.S. you will still need to include the "Repartition=no" setting in your .sif file, otherwise you'll get the single NTFS partition
