I want to make a multiboot DVD with Win7 SP1 Media Refresh (X17-59463.iso) and Windows XP SP3 i read elsewhere about using WAIK, but on the Microsoft site it is listed as a 1GB download, plus a extra 1GB file for the Win7 SP1 supplement, so i want to ask, what is the simplest way of making a multiboot DVD with Win7 SP1 + XP SP3 very much appreciated. edit: will also use the Ei.cfg Removal Utility on the win7 iso, its compatible with sp1 right? and the sp3 iso is corporate version with updates till April 2011
