GRUB/os-prober won't recognise Arch on Windows

Before you mark as duplicate, this is not the same as https://bbs.archlinux.org/viewtopic.php?id=262640 in that I have two different efi partitions on two separate drives

so an image:

sidenote: there is a windows part on the efi of the 1tb (the one with linux) drive but i think its trying to boot D:\ and it goes into automatic repair. D:\ is extra storage part for windows (games, movies, visual studio...)

anyway, hence the title, os-prober wont recognise the efi partition on the 2nd drive (the windows one) and, yes, i did the grub_disable_os_prober=false thing.

You need to mount the secondary ESP "somewhere" before it's going to be considered by os-prober, did you do that?

"Somewhere" it doesn't matter where (other than, don't mask over other partitions you'd want to be considered), pick /mnt or whatever, it just has to be mounted, os-prober parses the mount table and then checks for relevant boot loaders/kernel to generate configs for from there, you just need to do this once during the initial config creation.
