A set of .NET Framework managed libraries for developing graphical user interfaces.
I know this is old, but my computer did the same thing today after a Windows Update (by coincidence). Somehow my Boot Configuration Data (BCD) changed to my E-drive. I had to change it back to my D-drive (which is where my Windows Installation is on Boot).
When Windows failed to repair my PC, my PC loaded a screen with Advacned Options or Troubleshoot.
I had to: (screenshots are just examples)
- Select: (I think it was this order. The point is to get to Command Prompt)
- Advanced Options
- Troubleshoot
- Command Prompt
- I determined which drive contained my Windows installation. Run the commands in Command Prompt:
-
diskpart(wait for it to load DISKPART>) -
Then typelist volume(This shows all drive letters under Ltr) -
Then type exit.
-
- Next I verified which drive has my Windows installation by checking the drives:
-
dir C:\ (or D:\, E:\, etc...) - Look for the drive containing folders such as:
Windows, Program Files, Program Files (x86), and Users
-
-
bcdedit (This displays the current boot configuration.) - Use commands below to change device and osdevice entries to the drive Windows is installed on.
- Change D: to the drive that contains the Windows installation files.
-
bcdedit /set {default} device partition=D: -
bcdedit /set {default} osdevice partition=D:
-
- Change D: to the drive that contains the Windows installation files.
