On nvme1n1 partition 1 is 1gig for both EFI and /boot (with a minimal .iso available via grub as a rescue option if needed). With regards to windows making a tiny EFI partition on drive 0, i dont think I understand the issue. I'm thinking I can either; 1. Use the EFI boot loader to choose between Windows and Linux, as you mention above, with the small downside of having two boot loaders/timeouts, or 2. Use EFI to default to grub on the second drive with a very short timer (so its like its not even there) and put an entry for Windows in the grub config I will probably try #1 first, then update the grub config to boot windows and confirm that works, then change to #2. Let me know if i'm misunderstanding anything. Thanks!
