Fix: The Windows 7 partition must be the Active Partition.

If you are used another partitioner, like me, I used linux to get rid of that 100MByte windows partition, and installed linux next onto another HDD, I needed to pull of the cables from the linux HDD and then using only the Win7 HDD I can install Win7 SP1. I hope it's a solution for your problem.

If you still can't install it, or the linux is on the same drive, I think there's no solution. Only to re-partition the whole HDD and use Win7 partitioner.

I performed the automount command successfully. Then restarted. Verified automount was still enabled and got the error still.

I'm in the same situation: Linux partition on the same drive and a deleted 100MB system partition. I've also posted this here:

Obviously there's NO way to install SP1 without this stupid and useless systen partition. :-(

I also ran the above command line program (DISKPART) follow the steps and it still didn't work. I too run Linux but NOT on another partition but on a separate HDD. So I will try unplugging the Linux HDD and then try to install the SP1. I will let you all know what my adventure brings me :D

Had the same problem - assign a drive letter to the 100MB partition before the C: drive using Computer Management/Disk Management and then set the partition active by right clicking on the partition. Then try to reinstall. Worked for me!

Oh, then delete the drive letter if you want to.

Hi .. I had the same issue. The diskpart wont do good for SP1 to install..Linux installation has nothing to do with this issue, dont jump onto reformatting the machine. Just go to Disk management, right click on the partition where the windows 7 OS is installed,and assign the partition as active(Click on Make as active). Run the install again and oila, got it running.

Ian Burgmyer replied on

To add to what Vikram said, there is another thing that could potentially be confusing the SP1 installer.

If you have your system configured to boot to a different hard drive (for instance, I have mine booting to my second hard drive, mainly to keep my operating systems from overwriting each other's MBR), you may have to set your system to boot directly from your Windows drive.

It's kind of odd, really. I've had my computer set up like this for a while and haven't ran into any issues installing service packs when I was running Vista.

Well to let you the rest of you know that all I had to do was physically unhook or unpluf my linux Hard Drive and allowed windows 7 to boot. Than I proceeded to download and was able install the Sercvice pack without any issue. Hope this help

Kind Regards;

Jason
