Hi, I read attentively tutorial and posts to create an unattended install of Windows XP but I still have a few problems : I have two hard drives and each one is separated in 4 partitions. I would like to install Windows in first partition of first hard drive, "Document and Settings" and "Program Files" directories in the second partition of first hard drive. So, in unattend.txt I set : ProgramFilesDir="D:\Program Files" CommonProgramFilesDir = "D:\Program Files\Common Files" ProfilesDir="D:\Document and Settings" When I launch the unattended install, all works fine but Windows install "Document and Settings" and "Program Files" in the first partition of second hard drive and call it D: I saw many methods to change drive letters after the installation but not during the installation. Is there a way to force Windows to install "Document and Settings" and "Program Files" in the second partition of first hard drive ? Thanks
