I made an attempt but I give up for now, sorry.
The Windows system restore is really too picky for me, unreliable and without compression, it gives me headaches.
In Win7pese or WinRE, I have no success for recognize the system image previously made on my external hard drive:
Windows cannot find a system image...I do not have time currently to look further, for hours, I hope someone else can help.
To enable Firewall, there is a shortcut "Firewall Enable " in System tools. It seems, indeed, required to search for a system image on the Network.
Otherwise, It is probably best to look at an alternative: Acronis, Macrium, Easeus,... They do the job really much better but without managing the windows vhdx files.
Good luck
