Hi, 

My ThinkPad P70 shipped with Windows 8, which I have replaced with Windows 10 by upgrading, then replaced with Windows 10 Pro by entering my Microsoft license key in the Settings application on Windows 10.

I have recently tried to reinstall Windows 10 Pro for a full (wipe & load) clean install by following these steps: 

• deleting the "c:\" and the "WinRE" partitions,
• creating a new "c:\" partition encompassing the full disk space previously used by "c:\" and "WinRE" partitions,
• formatting my new "c:\" partition
• and then installing a fresh Windows 10 Pro OS from Microsoft USB drive. 

Upon completion of Windows 10 Pro installation, the OS presented errors/ warnings that drivers could not be found, nor installed for the following:  (List copied from the Hardware Troubleshooter utility output report.)

• Microsoft Basic Display Adapter (1 instance)
• PCI Device (1 instance)
• Ethernet Controller (1 instance)
• Network Controller (1 instance)
• PCI Memory Controller (1 instance)
• SM Bus Controller (1 instance)
• PCI Data Acquisition and Signal Processing Controller (1 instance)
• PCI Simple Communications Controller (1 instance)
• Unknown device (4 instances)

As a result of the fact that these drivers were not found & not installed, I was not able to connect to Lenovo Support or Windows Update to download drivers.  I have subsequently reverted to a backup image of the old installation but, I am still hoping to be able to perform a full clean installation due to some security concerns that I presently have with the existing Windows 10 Pro installation.  

Can anyone suggest why these drivers were not found/ installed by the Microsoft Windows 10 installation? 

Do I need to download drivers for all of these devices individually (some of the devices being unknown), prior to attempting a clean install again?

Thank you for any help that you can offer,

Have you tried downloading the SCCM package for Windows 10?

See https://pcsupport.lenovo.com/us/en/products/LAPTOPS-AND-NETBOOKS/THINKPAD-P-SERIES-LAPTOPS/THINKPAD-P70/downloads/DS105232 and choose your applicable version. All drivers shoud be included here.

Hi,

Thank you for your suggestion!  I was not aware of the availability of this package of bundled drivers for my specific OS version and ThinkPad model.   

Sincere thanks,
