Ok, so if I understand correctly, once I have the USB Bootable Installer I should click on "Image Recovery" on the Windows menu?
No. You will be booting macOS Recovery.
Booting the USB bootable installer is described in the bootable-installer creation document.
Use it to erase the entire installation—the whole storage device, all partitions—and reinstall macOS.
Then boot macOS, and (following the linked instructions) then use Boot Camp Assistant to create a partition for and install Windows.
Re-installing Windows with corrupt partitioning means re-installing macOS, as that’s where the tooling runs.
Boot Camp Assistant is the tool always used to manage Windows partitions, too.
In short: Apple doesn’t provide a way to jump directly from a corrupt environment to Windows, and some tasks will expect macOS around.
Again, I'm not able at all to go back to the Mac side of things.
We’re working on that here, with the macOS re-install by creating and using the bootable installer.
Re-establishing Windows is well along the corrupt-partition sequence here.
Apologies if this might be a dumb question, I'm not very well versed on this sort of stuff.
Please read the links provided, and post any questions you might have as you follow those sequences.
