Windows won't load after I messed up the Partiotin settings :(

(EDIT: sorry for the TYPO in the Topic Name -  its meant to say 'Partition')

Hi,

i have messed up using Disk Management in Windows 10.

• I was deleting partitions on an external Hard Drive and then reformatted it. Then managed to set it as 'Active'. So I deleted it and reformatted it again.
• Then I set the largest partition on the C drive as 'Active'. I thought this was where Windows was and needs to be marked as such for the computer to boot.
• There were two other small partitions on the C drive. One was marked as recovery i think and I am not sure about the other.

Anyhow I have really messed something up as now I a message saying that the computer won't Boot:

FILE:   \Boot\BCD

STATUS:  0x000000f

INFO: The Boot configuration Data of your PC is missing or contains errors

Is there a way I can fix the labeling of the Partitions and get things back to normal?

Thanks

UPDATE:

OK, I have been doing a bit of research.

I have now:

• booted from a Windows 10 recovery USB
• Run Command prompt

I am thinking that I somehow need to use this to change the 'Active' partition.

From what i can gather I need to set the System Reserve partition as 'Active'. And make the C drive no longer 'Active'.

If anyone could verify this that would be really appreciated.

Thanks again.

YAY!!! Solved

OK. My panic is over. I managed to changed the Active partition.

if anyone is in the same boat reading this then here is the steps i followed (bottom of page for Win8/10):
