 Leftover junk prevents new installation in MDT 2008/2010 and BDD 2007 Minimize
Location: BlogsJohan Arwidmark    
Posted by: johan 11/2/2007

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)

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


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)


<?xml version="1.0" encoding="utf-8"?>
<unattend xmlns="urn:schemas-microsoft-com:unattend">
    <settings pass="windowsPE">
        <component name="Microsoft-Windows-Setup" processorArchitecture="x86" publicKeyToken="31bf3856ad364e35" language="neutral" versionScope="nonSxS" xmlns:wcm="">
                <RunSynchronousCommand wcm:action="add">
                    <Description>Lite Touch PE</Description>
                    <Path>cmd /c CleanSetupInProgress.cmd</Path>
                <RunSynchronousCommand wcm:action="add">
                    <Description>Lite Touch PE</Description>
                    <Path>wscript.exe X:\Deploy\Scripts\LiteTouch.wsf</Path>

ZeroTouch (SMS 2003 OSD FP)
Just add a winbom.ini that will wipe and format the disk... se below example...



Disk1 = Disk1.Config

WipeDisk = Yes
Size1 = *
PartitionType1 = Primary
FileSystem1 = NTFS
QuickFormat1 = Yes
SetActive1 = Yes

I am receiving this error running MDT 2010 Update 1. LiteTouch has encountered an error. I deleted the MININT folder but the message still pops up immediately after inputing the details to capture the reference machine. There was no _SMSTaskSequence folder on the drive. Any ideas? I don't want to run dispart and wipe the drive since I want to capture the machine.

Well, upload the bdd.log somewhere and post the link...

In general I don'r recommend using the capture only task sequence since it's buggy. I prefer the build and capture sequences which is rock solid...
