Leftover junk prevents new installation in MDT 2008/2010 and BDD 2007

One of the most common issues with MDT 2008/2010 and BDD 2007, LiteTouch and ZeroTouch, is leftover junk from a previous installation preventing a second installation to continue… The solution… Get rid of the junk…

Note: Make sure to do these changes only to the winpe images used for bare metal installations… (wiping the disk in the middle of a refresh installation might lead to , ehh, unexpected, results)

LiteTouch
Create a script that removes the MININT and _SMSTaskSequence folders (if present).

CleanSetupInProgress.cmd

If Exist C:\MININT\nul rd C:\MININT /s /q
If Exist C:\_SMSTaskSequence\nul rd C:\_SMSTaskSequence /s /q

Call the script from unattend.xml (in WInPE)
