in my case it is that grub and refind don't do well together. i
prefer booting via refind, but keep grub around just in case. i
have also now put a menu entry for grub to chainload refind.
in /etc/grub.d/40_custom i have:
=====
#!/bin/sh
exec tail -n +3 $0
# This file provides an easy way to add custom menu entries. Simply type the
# menu entries you want to add after this comment. Be careful not to change
# the 'exec tail' line above.
#
menuentry "Refind Menu" {
insmod part_gpt
insmod fat
insmod chain
root=hd0,1
chainloader /EFI/BOOT/BOOTX64.EFI
}
=====
but i also have this documented in another place just in case
grub deletes my 40_custom file.
