There might be a way:
Do a Macrium image of your C partition (verified).
Clean install Windows.
Boot to Macrium and copy the image of C back over the clean install C partition.
That will get your partitions back to where they need to be.

What do you think Brink?

The first step to determine the availability of the recovery partition is to open a command prompt (admin) and run:

reagentc /info

What results do you get?

ok, found the solution:

Create A New Recovery Partition

Note: here we take Windows 8 for example.
Step 1: Download your Windows ISO directly from Microsoft, which will require your product key to install. (Note: In many cases, this is included with your Windows computer.)
Step 2: Use Microsoft’s tool to create installation media for Windows.
Step 3: Look for the Sources folder, where you’ll find install.esd. This is the recovery partition, basically, but in its current state it is useless. To make it work for you, you have to first move it from the ISO or DVD to a location on your hard disk. Next, you need to convert it from install.esd to install.wim via some converters like WimConverter tool, and then copy the install.wim file to a new folder on your C:\ drive, labeled C:\Win81-Recovery. The next stage is to register the file so that Windows knows it is there and can create a recovery drive.
Step 4: Right-click the Windows Start screen button and select Command Prompt (Admin) on the desktop. Next, in the command line, enter:
REAGENTC /SetOSImage /Path C:\Win81-Recovery\INSTALL.WIM /Index 1
Tip: This will register the INSTALL.WIM file as your PC’s recovery image.



Step 5: Type: REAGENTC /Info.
Step 6: Type: exit.

You already have a recovery partition. You can try:

reagentc /setreimage /path \\?\GLOBALROOT\device\harddisk0\partition3\Recovery\WindowsRE

You want to use setreimage, not setosimage to set up the recovery environment

You can make sure the recovery partition is partition 3 by running:

diskpart
select disk 0
list part
exit
exit

thank you all!!!

I tried the conversion, got the error "Disk layout validation failed".



The computer has only one disk with two system partitions, a SRP boot partition and the Windows partition. Also an extended partition with two data partitions.
