I followed the instructions in the sticky to integrate x86 & x64 versions of vista into 1 install.wim, then I added the server 2008 files to the install.wim and used vmware to emulate the iso. Unfortunately when the install gets to the part where I choose which OS to install, it comes up with an error that it cannot find the install.wim even though it is there. BTW I used the Server 2008 bootup files, etc. Anyone know a way to get server 2008 x86/x64 and Vista x86/x64 to install from the same disc? Thanks
