cluberti, I think you are on the right track as the insertion of additional volumes ahead of the installation volume is essentially how I was able to load previous versions of Windows to a drive L. However, my attempts to do the same with a Windows 7 installation have not been successful. Perhaps I just haven't been doing this the right way. One thing I tried, for example, was to create three partitions -- the first a small primary partition for the system files (which the Windows 7 install apparently likes to create otherwise), the second an extended partition which I divided into several logical drives, and the third a large primary partition for installing the OS. There were enough logical drives ahead of the third partition that it would have been given the letter L if all of them were named in order. However, to my disappointment, it ended up as drive C, as usual. If you know of a better way, please tell me and I'll try it. For some reason this was a lot easier with previous Windows OS's. Other comments: 1. When this does work, I delete all the stub logical drives and merge them all into the first partition, so I end up with a small C drive with a few system files followed by a large L drive with the bulk of the OS and data files. This required a trivial adjustment to the boot.ini file, but then everything was fine. 2. I tried changing the letter of the Windows 7 C drive after an install but the OS won't allow this. 3. Based on a suggestion from someone on another forum I used the WAIK to create an "Autounattend.xml" file to use during the install from DVD process. This file is intended to facilitate automated installations but I used it because it offers the possibility to set many more options than the normal setup procedure. In it I told the setup to create two partitions, one for the system files and one for Windows 7, and to given them the drive letters C and L, respectively. The install, starting from a blank disk, worked fine, but alas, when it was all over the system files were in a hidden partition (of the size I specified) with no drive letter and the Windows 7 files were in the next partition (also as I specified) as drive C. I know the install paid at least some attention to what I specified in the .xml file because the system partition was formatted FAT32 as I had instructed. jjo
