Hello Everyone, first time in the forums.
I am having a problem to apply drivers to SCCM 2012 R2. 
The problem is the following: when I boot the machines into PxE (and later on to WinPe) it shows System Center Logo and later on reboots.
After some troubleshooting we could figure out it was do tue a driver missconfiguration.
We dowloaded all the Windows 7 drivers again and uploaded them to SCCM but it keeps happening.

Does anyone has any information that may be usefull?
I know tat .inf and .sys files need to be added to SCCM, I have decompresses all the driver packages in my computer and uploaded them to SCCM

The Laptop Models is: Latitude E7270

Thanks in advance.
