i have a windows install on disk 1, and arch linux on disk 2, i use the default 100 MB windows boot partition on disk 1 for both windows boot manager as well as grub to boot linux (os prober failed to add windows to grub, but thats of no issue)
id like to somehow make a boot partition an disk 2 and put grub there (only grub, i dont want to change windows boot mgr), but i understand thats not as simple as creating an arbitrary partition and installing grub there
