I am trying to install Win 7 SP1 (using Windows Update), but it failed with 0x800F0A12. I have a dual boot configuration windows - linux, otherwise perfectly normal configuration.
This web page: http://windows.microsoft.com/en-US/windows7/windows-7-windows-server-2008-r2-service-pack-1-sp1-installation-error-0x800F0A12 suggest some fixes, but only the first one seems relevant. However I get:
C:\Users\ga>mountvol /E Access is denied.
The main reason why I am so keen to have it installed is because Windows stopped recognizing my optical drive (it just completely vanished after one of the automatic updates). It might be related to this issue.
An ideas how to fix it?
Following @vcsjones' advice I managed to run
mountvol /E successfully, but it didn't help with the SP1 installation unfortunately.
