Dual Boot Batocera + LibreELEC

Hi everyone, I'm trying to do dual boot with the batocera and libreelec without success. I put the following entry in GRUB

menuentry "LibreELEC" {
set root=(hd0,1)
linux /KERNEL boot=/dev/sda1 disk=/dev/sda2 quiet
}

I get the message "error: file / KERNEL not found."
Any suggestion?

Sorry my english

Thank you! These solutions are for raspberry Pi. I am trying to do dual boot on desktop.

I know this is an old thread did you actually manage to get dual boot working ?
