I'm trying to install a system with Linux Mint, LibreELEC and Batocera.
Then I want to boot automatically to LibreELEC and within Kodi I want to boot to Batocera. For this I found an addon, but first I've to configure the whole system so I can choose with Grub2 my booting system.
So I installed LibreELEC as a standalone system on my HDD and made a backup with Clonezilla. Next the same with Batocera.
Afterwards I installed Linux Mint and created an extended partition with logical partitions where I restored my clonezilla-backups.
At least my partition looks like this ->
/dev/sda1 -> ext4 -> Linux Mint System partition
/dev/sda2 -> extended partition
/dev/sda5 -> linux-swap
/dev/sda6 -> ext4 -> LibreELEC-System
/dev/sda6 -> ext4 -> LibreELEC-Data
/dev/sda6 -> vfat -> RECALBOX (Batocera System)
/dev/sda6 -> ext4 -> SHARE
Booting of LibreELEC is no problem.
I'm using folowing command in Grub2 ->
search --set=root --label LE_SYSTEM --hint hd0,msdos7
linux /KERNEL boot=LABEL=LE_SYSTEM disk=LABEL=LE_DATA quiet
But Batocera doesn't start with Grub2.
I tried following command in Grub2 ->
linux /boot/bzImage label=RECALBOX console=tty3 debugging loglevel=0
I tried also hd0,8 and hd0,10.
But everytime I'm getting messages like Kernel not loaded. In my mind the parition won't be loaded?!
I also created a fresh ext4 partition instead of vfat and copied only the files from the downloaded image.
Maybe someone has a hint or a solution for that problem :-)
