rEFInd best configuration for dualboot Ubuntu 20.04 (kernel/GRUB) and Windows 10
Raw
README.md

You need to replace volume token with your PARTUUID

  • Use this command to find PARTUUID blkid -s PARTUUID -o value /dev/sdXY Where sdXX is your partition where located efi/kernel file

  • Replace here, here, and here

You need to replace "options" token with your options located in /boot/grub/grub.cfg

grub.cfg here only for example, use your own /boot/grub/grub.cfg instead

Also you can uncomment line here to hide about and hidden_tags menu entries

But before we need to hide unused entries, such as

  1. Autodetected boot entries (GRUB, kernels, Windows Bootloader)
  2. MOK Manager
  3. etc.

Don't forget to include this configuration in refind.conf

# Which non-bootloader tools to show on the tools line, and in what
# order to display them:
# shell - the EFI shell (requires external program; see rEFInd
# documentation for details)
# memtest - the memtest86 program, in EFI/tools, EFI/memtest86,
# EFI/memtest, EFI/tools/memtest86, or EFI/tools/memtest
# gptsync - the (dangerous) gptsync.efi utility (requires external
# program; see rEFInd documentation for details)
# gdisk - the gdisk partitioning program
# apple_recovery - boots the Apple Recovery HD partition, if present
# windows_recovery - boots an OEM Windows recovery tool, if present
# (see also the windows_recovery_files option)
# mok_tool - makes available the Machine Owner Key (MOK) maintenance
# tool, MokManager.efi, used on Secure Boot systems
# csr_rotate - adjusts Apple System Integrity Protection (SIP)
# policy. Requires "csr_values" to be set.
# about - an "about this program" option
# hidden_tags - manage hidden tags
# exit - a tag to exit from rEFInd
# shutdown - shuts down the computer (a bug causes this to reboot
# many UEFI systems)
# reboot - a tag to reboot the computer
# firmware - a tag to reboot the computer into the firmware's
# user interface (ignored on older computers)
# fwupdate - a tag to update the firmware; launches the fwupx64.efi
# (or similar) program
# netboot - launch the ipxe.efi tool for network (PXE) booting
# Default is shell,memtest,gdisk,apple_recovery,windows_recovery,mok_tool,about,hidden_tags,shutdown,reboot,firmware,fwupdate
#
#showtools shell, gdisk, memtest, mok_tool, windows_recovery, reboot, exit, firmware, fwupdate
