Since the OP has not yet responded, I will go ahead and post this. Hopefully I understand the situation correctly.
At the end of the post, I have included a copy of the actual procedure done in the Command Prompt Window.
********************
Start by opening an Administrative Command Prompt (Winkey+X and select)
Then start Diskpart to add the drive letter and check what all the Volume letters. Using these commands the drive letter for the primary drive is assumed to be 0. If it is something else in the lis dis command, use that number. Most of the commands can be done using only the first 3 letters.
Diskpart
list disk
select disk 0
list partition
select partition 6 <--assuming partition 6 is the one we need
assign letter="R"
exit
Now we need to find the path to the image file by using normal DOS commands.
R:
dir /a
If you show a folder, then you need to go until you see an
install.wim file. The
dir /a command shows hidden files an you may need to use it. Return to the C: drive to finish.
Once you have the path to the image, you can use Reagentc to set it. Type reagentc /setosimage /? for help on the command if you want. The spaces in all commands are required.
Assuming the path to your image file is
r:\RecoveryImage\install.wim use it in the command below.
reagentc /setosimage /path r:\RecoveryImage /index 1
You should not need to give the command a Target while online, but if it
does not work for some reason you can include it.
reagentc /setosimage /path r:\RecoveryImage /Index 1 /target c:\Windows
You should be able to run
reagentc /info again and show the Recovery Image location. If it has worked, we need to remove the drive letter from the Recovery Image partition, so start Diskpart again and change the commands above to use remove instead of assign.
Diskpart
list disk
select disk 0
list partition
select partition 6 <--assuming partition 6 is the one we need
remove letter="R"
exit
You should be done. If it is done correctly, it should work unless the version numbers interfere with the operation. Do not choose the "clean all drives" option during the reset. I have also reset to a clean OS partition, but it does have to be formatted first, if you need to go that way. I cannot test your exact situation, so take whatever precautions you feel necessary.
You should now be able to make a Recovery drive which will copy over the contents of the recovery folder. The reset process is very picky and any changes in the other required partitions will cause it to refuse the operation. If you cannot get this process to work for you, since you have the necessary image, we could use DISM to apply the image to the OS partition and set up the recovery options after that.
