Start CHKDSK / R from the recovery console.
If your computer does not start in safe mode (f8) and the Recovery Manager (f11) is not running, the Windows Recovery Console can start and execute CHKDSK / R to correct the original Unmountable_Boot_Volume error. The following steps explain how to access the command window from the recovery console.

Recover the Master Boot Record (MBR).
MBR is the type of information stored in the first sector of the hard disk. It determines the location of the operating system on the hard disc, allowing you to load it into the main memory (RAM) of your computer. Recovering the master boot record may eliminate the error of the uninstalled boot volume.

- In the Advanced Settings screen, click Command Prompt to activate the Windows Command Prompt console.
- From the command line, type the following commands in order, and then press Enter.
bootrec / RebuildBcd
bootrec / fixMbr
bootrec / fixboot / fixboot
Enter the exit command after the above commands have been executed. Then reboot the computer.
Restoring Drivers for Hard Drive Controllers with System Restore
Most of the driver-related causes of this error can be resolved by reverting to a previous system configuration using System Restore.
Windows usually runs an explicit system restore point when installing, updating, or removing certain drivers. This means that 9 out of 10 cases, if the UNMOUNTABLE_BOOT_VOLUME error was caused by a change in device drivers, a system restore point must be available to repair the damage.
System Restore, available through the bootable Recovery / Recovery Console included with the Windows Vista, Windows 7 and Windows 8 installation DVDs, can be used to display a list of “snapshots” of your PC from different minutes ago and try restoring your computer to your chosen point recovery. System Restore is “non-destructive” because it only affects Windows and programs, not your personal files and folders.
