Windows 7: Created boot partition manually, Service Pack update error 0x800F0A12

[SOLVED] Created boot partition manually Service Pack error 0x800F0A12

I reinstalled Windows recently, but it used the same boot partition from my old installation. I got rid of the old partition (it was on the wrong hard drive) and created a new one with the repair disc. Windows boots, but won't install updates. Bcdedit outputs
The boot configuration data store could not be opened. The system cannot find the file specified

I think it can't find the boot partition. Is there anything I could set so that it knows where it is? Thanks.

Could you use the snipping tool to take a picture of your disk management window and attach using the paperclip?

Is the old drive still in your system, and if so have you tied removing it?

The other drive is Disk 0. It's been reformatted for storage.

Two things I see in that pic:

Several partitions are marked active unnecessarily.

The C partition is not shown as Disc 0. Instead you have the storage drive G as disc 0. You should be able to change that by swapping the drive cables at the motherboard connection inside the case.

But I'm not sure any of that should have any effect on getting Windows Updates. You may have something else going on.

If you are trying to get Service Pack 1, I'd try to download it separately and install it directly, rather than relying on Windows Update for that purpose.

The active partitions, as mentioned do give you a better chance of having a problem if the drives were to get out of order. But it looks like you are booting to the 119 GB drive. You should be able to disconnect, if you wanted, the other drives and still boot.

If the system boots, it should be able to see the BCD Store, since it needs it to boot, but I have seen some strange things where it might have still been on an inactive partition and was being used by the bootmgr on the active parition.

How did you load the boot files in the 100mb partition on the 119 GB drive? If you set the folder options to see Hidden system files, you can look for "Boot" folders and a bootmgr file to see where they might be.

But to avoid confusion, I would disconnect the other drives and run a Startup Repair.

Ok thanks, I'll try that. Is there a way to unmark them as active?

Ok, I finally got around to unplugging my drives (I'm usually on Linux), and this fixed it. This seems like a stupid system though, I feel like there should be a config file or something to edit in order to point to the boot partition.
