I have a new copy of Windows XP Professional (SP2) that I would like to
install on my Lenovo laptop. My plan is to partition the HDD with a system
partition (C:), programs partition (D:), and data partition (E:). I would
like the default drive for new programs to be D and would like for the
Documents and Settings Folder for all users to reside on the E drive.

(During installation, I plan on just formatting the C drive leaving a large,
unallocated space.  Once XP finishes installation, I'll go back using Disk
Management to create the D and E drives off the unallocated space.)

I've never messed around with editing the Registry so I understand I may be
able to do this using an "unattend.txt" file during installation. How can
this be done with the new Windows XP CD I purchased?

Thanks in advance.
