Ok that makes sense. What threw me off was this thread. http://forum.driverpacks.net/viewtopic.php?pid=29826
People talked about installing Windows from the I386 folder. How were they doing that?

I'm trying to install WinXP from a bootable UBCD4WIN usb flash drive. I read the thread here that Driverpacks looks for the I386 folder in the root so I moved I386 to the root of my flash drive, but I still get this error message.

I'm able to boot into UBCD4WIN & run the command "X:\i386\winnt32.exe /syspart:C: /tempdrive:C: /makelocalsource /noreboot"  which copies the windows files to my "c" drive. I then reboot & windows continues the installation only to stop when it can't read the setuporg.exe file. At this point Windows is copying the files from my hard drive (C drive) not my flash drive so having the I386 folder in the root of the flash drive makes no difference. How do I point it to the I386 folder on my hard drive? Thanks.
