See if an offboot sfc /scannow will fix it.
Change the boot order and boot up with the disk - after pressing any key to boot from CD/DVD you may be presented with an inverse screen with an option to press F8
Having done that, select Safe Mode with Command Prompt where you'll be presented with a splash screen to select Repair your Computer.
Confirm or change the keyboard/currency then follow the prompts to navigate to the Recovery Environment and select Command Prompt.
At the prompt enter bcdedit |find "osdevice" and using whichever partition letter it gives, enter (assuming c) -
sfc /scannow /offbootdir=C:\ /offwindir=C:\Windows
There is a space before each forward slash and that's a Pipe symbol before find.
This way sfc has an incorrupt volume to repair from.
Enter exit when done to close the command window, remove the disk then click on Restart to see if that has resolved, depending upon what sfc reports.
