Install Problems Win 7 SP1

I tried unsuccessfully to install SP1 for Windows 7. The install fails I think because of how the SSD is formatted by Sony. Any suggestions on how to accomplish the update appreciated Error message follows.

Windows 7 and Windows Server 2008 R2 Service Pack 1 (SP1) installation error: 0x800F0A12

If you receive error "0x800F0A12" when trying to install Service Pack 1 (SP1) for Windows 7 or Windows Server 2008 R2, it means the installer can’t access the system partition of your computer’s hard disk to update files.

Usually, this partition is accessible to Windows (although you can't browse it in Windows Explorer). However, in some situations, access to the system partition might be blocked after Windows has started. For example:

*

The system partition isn’t automatically mounted, or made accessible to Windows, during startup.
*

A hard disk containing the system partition was removed prior to beginning SP1 installation.
*

Windows is running on a storage area network (SAN), and access to the system partition has been disabled.
*

A disk management tool from another software manufacturer was used to copy (or clone) the disk or partition on which you’re trying to install SP1

 

Had same error. The following worked for me today:

go to command prompt

enter command: mountvol /E

reboot

After reboot, install SP1
