Bootcamp: "Bootmgr is missing" at boot after OSX 10.13 High Sierra upgrade

Hi,

Following the upgrade to OSX 10.13 High Sierra on a mid 2012 2,3 GHz Intel Core i7 MacBook Pro containing a Bootcamp partition with a Windows 7 Ultimate on it, it became impossible to boot natively under Windows.

Windows complains saying: Bootmgr is missing.

The files from the BOOTCAMP Volume are still accessible from OSX

I tried to boot into the Windows 7 installation disk from a USB key to "Repair Startup Problems"

I tried to fix the boot record using these commands

bootrec /fixmbr

bootrec /fixboot

bootrec /rebuildbcd

I did all this both natively or from a VMWare Fusion Bootcamp VM

But none of this restores the boot record properly

Here is the output of

diskutil list
