The grub menu from one Fedora 33 with btrfs cannot register an entry for( any other btrfs based distribution) To boot the alternate Fedora33, I have to enter the bios.
Can someone post an example of a chainloader entry for /etc/grub.cfg
which will allow the first Fedora33 to boot the second fedora33
#!/usr/bin/sh
exec tail -n +3 $0
# This file provides an easy way to add custom menu entries. Simply type the
# menu entries you want to add after this comment. Be careful not to change
# the 'exec tail' line above.
menuentry 'FEDORA 33 on B' {
search --fs-uuid --no-floppy --set=root D78C-9DB84 #<< change UUID as necessary
chainloader (${root})/EFI/fedora/grubx64.efi
}
===========
The replace the UUID D78C-9DB84 with the UUID of /boot/efi of the target system.
This will create a grub.cfg entry which will allow you to boot a second btrfs based FEDORA33
Save it as /etc/grub.d/40_OtherFedora . Prefix must be 40_ followed by your chosen name.
