I am working on a similar method of having one interface for the install of serveral OSes. The HTA interface is setup with dropdowns for OS, Hardware,... and then generates an unattend.txt file to a 'cleaned' c: drive. The OS source files are on a 2nd CD. The problem I have run into is that WinPE will allow the CD to be changed and keep running (using the /inram switch), but winnt32 will not start running from the 2nd cd when it's swapped. I tried to copy the I386 folder to the C: and start Winnt32 from there and it worked, but it's not pretty or fast to copy the CD to the C: Drive. Any experience with using a second CD for OS installs from a PE boot?
