Windows 10 - Recovery - System-Reset failed - Workaround: add most recent drivers to WinRE

Some Windows 10 builds do not support the most recent HW models / most recent chipsets, network adapter, SATA because of missing drivers in WinPE / WinRE

If you try to reset a unit to the initial OOBE / AutoPilot-Config  then you may see only a screen like this

Prepare your "System-Reset" test using a DELL ImageAsist image
######################################

• Download ISO via MS MediaCreationTool Windows 10 - e.g. 20H2 / 21H1
• Installation on a virtual machine – no customizations
• Use Dell ImageAssist => Capture.WIM
• Dell ImageAssist USB key – restore image on a very recent hardware model
• Run OOBE - all OKAY

Try to initiate a "System Reset"  ( either MS-Intune or "ReAgentc.Exe /BootToRE") 

• Reboot
• "System Reset" failed - hard disk not found
• Same failure if system reset is initiated by Intune
• Same failure if system is installed without any network connectivity ( no Cloud, no Intune, no domain)

Workaround: 

before you apply the Captured.WIM to any physical unit modify the Captured.WIM 

1) Download most recent WinPE10-DRV-CAB  ( www.dell.com/FamilyPacks)

2) extract subfolder x64 of WinPE10-DRV-CAB

3) mount Captured.WIM

4) Mount WinRE.WIM (part of captured.WIM):    \Windows\System32\Recovery\WinRE.WIM)

5) Inject WinPE10-DRV to WinRE.WIM

     Dism /Image:C:\WinREMount /Add-Driver /Driver: /forceunsigned /recurse

6) Unmount WinRE.WIM

7) Unmount Capture.WIM

Apply DELL ImageAssist Capture.WIM to physical unit, finally test System-Reset

Bug-FIX - when unit is already delivered

a) Disable WindowsRE    - ReAgentC.exe /Disable

b) Mount    C\Windows\System32\Recovery\WinRE.WIM

c) Inject WinPE10-DRV (only x64) to WinRE.WIM  - described above

d) unmount WinRE

e) Enable WindowsRE    - ReAgentC.exe /Enable

f) Test "System Reset"
