MDT / LiteTouch rebooting in loop

This can happen when these folders still exist on the computer or on your litetouch media. (Usually from a previous mdt type installation)

• _SMSTaskSequences
• MININT

Steps to solve the issue

• Delete the folders

OR

• Boot into your litetouch environment

• Press F8 as soon as you see the background

• Type the following:

• Diskpart

• Select Disk 0 (Make sure this is the disk you want to erase/format)

• Clean

• Reboot the computer and boot into the litetouch environment or type startnet.cmd

Using MDT with Lenovo hardware

Some of you may already know this but the %Model% variable within customsettings.ini will not work for Lenovo based hardware. This is due to the fact Lenovo puts their "model type" in that field, and puts the actual model name in the Version field.

So this leads to issues when trying to inject drivers or software based on lenovo model,

But do not fret, there is a solution!

Once implemented you can then use the %LenovoModel% variable in customsettings.ini

Modify the ZTIGather.wsf to create a new LenovoModel variable
