+# 🖱️ HP G7/G8 Touchpad Issue in WinPE
+
+On **HP ProBook G7/G8**, the **touchpad may not work in WinPE**.  
+HP confirmed this is related to a **missing chipset driver**:

+## 🔧 Fix: Inject Drivers into WinPE
+
+1. Mount the WinPE image:
+   ```powershell
+   dism /mount-wim /wimfile:"\\ServeurLDMS\ldmain\landesk\vboot\boot_x64.wim" /index:1 /mountdir:c:\mount
+   ```
+ 
+2. Inject the touchpad drivers:
+   ```powershell
+   Dism /Image:C:\mount /Add-Driver /Driver:"c:\WinPEDriversPbTouchPadx64" /Recurse
+   ```
+
+3. Commit and unmount:
+   ```powershell
+   Dism /unmount-wim /mountdir:c:\mount /commit
+   ```
+ 
+ ## ⚠️ Notes  
+- Make sure the drivers in `c:\WinPEDriversPbTouchPadx64` are the correct ones for your HP model.  
+- Always back up your original `boot.wim` before modification.
