Yes, that's a frustrating situation. Suggestions from the ConfigMgr support team:
Use the below steps: 1) Before the Format and Partition Disk tasks, use the Set Task Sequence Variable task to set OSDPreserveDriveLetter to False 2) In the Format and Partition Disk tasks, set the option on all partitions to not assign a drive letter EXCEPT for the partition where you plan to install Windows 3) In the Format and Partition Disk task, on the partition where Windows is being installed, assign the partition a variable 4) In the Apply OS task, tell it to install on the partition specified by the variable in Step 3 The above will do the following: 1) Since no partitions are assigned drive letters except for the Windows partition, that partition is guaranteed to get C: since the first (and only) partition always gets assigned C: 2) C: will be assigned to a variable, and then via that variable you are "specifying" to install on C: at the Apply OS Task This has worked for me every time and has also fixed several customers I have worked with that has had this problem.

I have an SCCM 2012 R2 server set up and a "native" (no MDT integration) OS deployment task sequence. I'm deploying the factory install.wim. I use a collection variable to set OSDPreserveDriveLetter to False. This works fine, my OS (Windows 7,8,8.1) install fine and show up on the C drive. So far, so good. I then install MDT2013 and create an MDT integrated task sequence. I deploy it to the same collection as my non-MDT integrated task sequence and I have not touched the "Set Variable for Drive Letter" within the task sequence that sets OSDPreserveDriveLetter to false. But when I deploy Windows 7 using it the OS drive is D:. Is there a trick to get the MDT integrated task sequence to install the OS to the C drive?
