I'm getting the error 0x800F0A12 which is described here.
bcdedit
says:
C:\>bcdedit.exe
Der Speicher für die Startkonfigurationsdaten konnte nicht geöffnet werden.
Das System kann die angegebene Datei nicht finden.
(English: Couldn't open the start configuration. Couldn't find the file.)
(off topic: how can I get those messages in English?)
I played around and I assume that is because the system partition C:\ is not on the first BIOS disk.
There are 4 disks in my PC. On one of them (shown as the 4th in Windows drive manager) contains Windows, whereby the system-reserved NTFS partition is the first primary and the second primary is my main Windows system partition. A few more partitions follow with other (non-NTFS) stuff. I was able to set the first two disks offline (via the Windows drive manager). For the 3rd disk, it says that it cannot set the BIOS 0 disk offline.
How can I ignore that and still install SP1?
I don't want to rewire/resetup my disks.
You might encounter an issue during the installation of SP1 for Win7/R2 where the installer exits with: 0x800f0a12
This is due to the automount policy for your machine being set to disable. We block the service pack installation in these cases because we need to be able to write information to the BCD store during install and with automount turned off, we are not able to. To resolve this, re-enable automount and then install the service pack. Quick steps to do this in case you forgot are:
Run DISKPART
automount enable
Restart
Install SP1
