When the unmount finishes, in that elevated Commmand Prompt launch diskpart (that is, type "diskpart" without the quotes and hit enter), and at the DISKPART prompt type

list vol

and hit Enter. Look for your MSR partition and note its number. You need to assign it a drive letter so it can be a target for xcopy. Type

sel vol (your MSR volume #)

and hit Enter. That volume will now have focus. Now type

assign letter=z

and hit Enter. Z is far enough down the alphabet that it shouldn't interfere with any drive letters actually in use. (If you're using Z, choose a different, unused letter). Once that is complete, exit DISKPART, but don't exit the elevated Command Prompt. It helps (me, anyway) to label my partitions/logical drives. So I typed

label Z:Recovery

and hit Enter.

We'll be using reagentc to set the path for the Recovery Environment, and it can't set the path to the root of a drive, so we need to have a folder in drive Z: At the Command Prompt, type


and hit Enter. Next use the Make Directory command to create a folder to be named WindowsRE. Type

md WindowsRE

and hit Enter. Now we're ready to copy the Winre.wim file.

Use xcopy to copy winre.wim (from wherever you saved it) to Z:\WindowsRE, using the /h /r switches. Once that's accomplished, you need to let the system know that it's there. In the elevated Command Prompt, type

reagentc /setreimage /path z:\windowsre

and hit Enter. Next type

reagentc /enable

and hit Enter. If that is not successful, type

reagentc /info

and hit Enter. This will give configuration data for windows RE. This site has some excellent information for troubleshooting.

Once you have the Recovery Environment enabled, go back into DISKPART and remove the drive letter. Type

list vol

and hit Enter. Then type

sel vol (your MSR volume #)

and hit Enter. That volume will now have focus. Now type

remove letter=z

Now you can exit DISKPART, and the elevated Command Prompt.

To see it if worked, go to All Settings > Update & Security > Recovery and click Restart. Windows RE should be one of the listed options.

After getting it working properly, I decided to take it away from Windows. Using BootIt UEFI I did some rearranging on a differend physical drive, and created a 1GB partition at the beginning of the drive. I then created a drive image of my Recovery Partition and restored it to its new home. I used the above steps to get it enabled in its new home, then formatted the original old partition.

With the Recovery Environment

in its own partition, Windows is neither booted nor its files in use, you're not in a folder in the Windows OS partition, and troubleshooting Windows problems is quite convenient. A Windows image can be quickly restored, or other tools that can be incorporated into the Recovery Environment are accessible as well.
