Windows still likes to occasionally clobber your EFI entries and wipe out grub if it sees it.
Is there an easy-to-understand tutorial?
For dual boot I have been relying on Grub to boot Windows which it still does fine with UEFI.
The one annoyance was that the Windows installer makes a puny 100MiB ESP by default, which would actually be enough for everything I have on there at the moment, but it felt small so I bumped it up to 1G before installing the second OS.
