1. Boot into Windows Server 2008 R2 Setup and select "Repair your computer" then select Recovery Tools and then "Command Prompt" from System Recovery Options.
2. When in recovery mode the disk drives end up with different drive letters than what the normally have.
Find your drives: (C or X or virtual/temp Windows drive); (D or E for system drive C); (D or E for D drive)
3. Copy C:\Users and C:\ProgramData to D:\Users and D:\ProgramData
robocopy /mir /xj E:\Users D:\Users
robocopy /mir /xj E:\ProgramData D:\ProgramData
/mir mirror files and security
/xj exclude junction points
4. Remove C:\Users and C:\ProgramData
rmdir /S /Q E:\Users
rmdir /S /Q E:\ProgramData
5. Create juntion points
mklink /J E:\Users D:\Users
mklink /J E:\ProgramData D:\ProgramData
Do not use the /D switch. Using /J, when Windows looks for the C:\Users dir, it will find it! But it will be on the D: drive instead of the C: drive. It will allow access to files within the directory via Windows Explorer and Command Prompt.
6. Verify.
dir e:\
you’ll see: "Users [D:\Users]" and "ProgramData [D:\ProgramData]" on the C: drive.
7. Restart server and log back in to see the changes.
dir c:\ /a
dir d:\ /a

ProfilesDirectory
Use this setting only in a test environment. If you change the default location of the user-profile directories to any volume other than the system volume, you cannot service your image. Any updates, fixes, or service packs may not be applied to the installation.
ProgramData
Use this setting only in a test environment. If you change the default location of the program-data folders to a volume other than the system volume, you cannot service your image. Any updates, fixes, or service packs may not be applied to the installation.
Windows® 7, Windows Server® 2008 R2, Windows Server 2008
ProfilesDirectory
You can change the default location of user-profile directories to a volume other than the system partition. However, do not move the default location of the user-profile directories to another volume except when deploying to the destination computer during Windows Setup. You cannot capture an image that has a user-profile directory in a nondefault location, because running sysprep /generalize on a Windows image that has user profiles on another volume is not supported.
ProgramData
Use this setting only in a test environment. If you change the default location of the program-data folders to a volume other than the system volume, you cannot service your image. Any updates, fixes, or service packs may not be applied to the installation.
Moving folder locations during deployment using unattended installation from installation media method.
1. Download and install the latest WAIK for Windows 7/Server 2008 R2 from Microsoft.
2. Use Windows System Image Manager WSIM to create the answer file.
a. Create, format and modify partitions using Microsoft-Windows-Setup/Disk Configuration component
b. Specify OS image install location using Microsoft-Windows-Setup/Image Install/OSImage/InstallTo
c. Specify folder locations using Microsoft-Windows-Shell-Setup/FolderLocations
d. Validate, and save file as AutoUnattend.xml
3. Copy AutoUnattend.xml file to removable media (USB flash drive, floppy disk or image)
4. Boot system to be deployed up from DVD media or ISO image and make sure removable media (Usb flash drive, floppy disk or image) is inserted so setup can find the autounattend.xml file and use it for unattended installation.
