If the issue still persists: Advanced Troubleshooting

Run System File Checker (sfc.exe) offline using two additional parameters, via the Windows Recovery Environment (Windows RE).
Note: you will need Windows installation disk or .iso image.
 
1.      Configure the virtual machine boot order such that the first boot device is your CD/DVD drive.
-    Without starting your virtual machine go to ‘Virtual Machine’ menu ► choose ‘Configure...’ ► select ‘Hardware’ tab.
-    Highlight ‘CD/DVD 1’, make sure that ‘Connected’ option is enabled and set ‘Connect to’ to your physical CD/DVD drive (if you have an installation disk) or specify the path to corresponding .iso image.



- Highlight ‘Boot order’ ► on the right side of the window, choose CD/DVD, and using the up arrow move it to the first place.



2. If you use a Windows installation disk please insert it into the CD-ROM, start your virtual machine.



3. When prompted, press a key to boot from the DVD. In the ‘Install Windows’ screen, click ‘Repair your computer’.



4. Select 'Troubleshoot’ ►'Advanced Options'.

  

5. Click ‘Command Prompt’.



6. First use the command line to identify all drives attached to the system and their current mount point in Windows PE. This is done with the diskpart utility and the list volumes subcommand. C:\ is the boot volume (labeled "System Reserved") and D:\ is the system volume (where the operating system and user data are stored)



7. Run a chkdsk, this will verify/repair the filesystem and mark any bad sectors on the disk so that they are not used again.



8. Perform a sfc /scannow using the offline settings for the boot directory and windows directory. If you use the incorrect options, two errors are common:




The first error indicates an invalid boot or system partition path. The second indicates that incorrect arguments were given, or there is a file that needs to be removed or renamed in the \Windows\winsxs\pending.xml path. For this installation, this is D:\Windows\winsxs\pending.xml.

For this particular system, this is the correct command to run based on the output of diskpart above





9. This process takes some time to complete.  Windows Resource Protection should find corrupt files and repair them. Details are included in the CBS.log.
10. When it completes type ‘exit’ (without quotations) and restart your system.
11. Go to ‘Virtual Machine’ menu ► choose ‘Configure...’ ► ‘Hardware’ tab ► highlight ‘Boot Order’ and change the order back (make Hard disk to be in the first place).
12. If the system is still unbootable, it may be necessary to perform an in place upgrade or rescue the files and create a new virtual machine.
