AlienRespawn on SSD : "Cannot create the system partition"

I have an Alienware M14x with a SSD.

It is a small 220 GB SSD so there is no system partition. Evrything is on the same partition.

I want to make a factory reset on my computer. I moved to Windows 10 and the WIFI card now create bluescreen errors. Maybe a drivers problems but I cannot find a fix. The computer is to old to get Windows 10 support from DELL. So getting back to Windows 7 maybe a good try.

The problem I encounter now is that I cannot make the factory reset.

I dowloaded the latest AlienRespawn update and get a valid respawn partition.

When I restart the computer and launch AlienRespawn I get an error message like : "Cannot create the system partition." Of course, there is nothing like a "system partition" because evrything is on the same partition.

Do you know how can this be fixed ?
