I have a problem with x64 multiboot install. I've followed these discussions for a while and built my multiboot dvd. I have a multiboot DVD that installs almost all versions of server OS including x64. The DVD has worked great and had no issues specific to x64 builds until we got some hardware with AMD processors. It boots and complete the text mode install but when it goes into the gui mode setup, it complains it can't find the catalog files at the 39 minute mark(nt5inf.cat, nt5.cat, ntprint.cat, ntiis.cat, ims.cat, wmsoem.cat, iasnt4.cat, wow64.cat, wowlang.cat, mstsweb.cat, oembios.cat, scw.cat) I have to manually point it to the CD folder for each catalog file (i.e. d:\setup\2003x64\sp1\ent\amd64\). Once I do that for all the catalog files, it continues on until about the 12 minute mark and complains it can't find outlook express. I can skip those files and the OS install completes and it will boot into the OS, but it seems WMI doesn't install. Any ideas? Once again, this only happens during x64 builds on AMD processors, x64 builds on Intel processors, it works flawlessly.
