You can find some examples on github with 'guix config'.
I have EFI Dual boot configuration here
https://gitgud.io/znavko/guix-configs/-/blob/master/guix-config-dual-boot.scm
bootloader field lookslike this:
(bootloader (bootloader-configuration (bootloader grub-efi-bootloader) (target "/boot/efi") (menu-entries (list (menu-entry (label "Ubuntu") (linux "(hd2,gpt3)/boot/vmlinuz") (linux-arguments '("root=/dev/sdc3")) (initrd "(hd2,gpt3)/boot/initrd.img"))))))
This bootloader configuration was made when I tried
to boot Ubuntu with grub command line.
I've found with grub's 'ls' command a linuz image
and initrd file and booted successfully.
After that I was sure such config will work.
I can't imagine troubles you will have with MS Windows.
May be easier it will be to use two different hard disks
and to change their order in BIOS?
