I have an ISO that I am having trouble with. My source disk is a XP Pro SP1 OEM (generic I think). I found a website http://xdot.tk/updates.html#fn13
that had two tools, Download UDC-01.14.13.zip for finding updates post sp3, and an IE8 add on creator, IE8.Add-on.Creator.zip. I also slip streamed SP3 and maybe removed a few things like tablet support. I tried to load it in Virtualbox and got an Error message when it started to format the disk. I have another ISO that just has SP3 sliped and it loads and works OK. Take a look at what I have and see if you can help me.

I'm not sure how to attach my Session.ini file.
