Installing Windows 7 SP1 on dual boot system

I had problems installing win 7 sp1 on the dual boot system which has ubuntu installed. The error was 0x800f0a12, which meant nothing to me.

According to source from MS, this was “due to the automount policy for your machine being set to disable”. Whatever that is, the solution is simple:

1. Run DISKPART

2. automount enable

3. Restart

4. Install SP1

Works for me, and it’s all that matters.

Windows 7/2008 R2 Service Pack 1 fails with 0x800f0a12
