Hi all, this is my first post . I've translated a guide found on this forum about slipstreaming Windows 7 SP1. The guide is pOcHa post #36 on "DVD with SP1 integrated into Windows 7 ?" thread. I can't post the like because I'm a new user. Of course my language is not english, so I can't still download the official ISOs from microsoft The problem is I cannot mix x86 editions (with slipstreamed SP1) and a x64 slipstreamed one. I'm getting a "missing driver" error just after pressing the "install button". For Example: Starter x86 SP1 + Home Premium x86 SP1 = working Starter x86 SP1 + Home Premium x86 SP1 + Home Premium x64 = working Home Premium x64 SP1 = working Starter x86 sp1 + Home Premium x86 SP1 + Home Premium x64 SP1 = NOT working (missing drivers) This is quite odd, isn't it? Any ideas on what could be wrong?
