Libreelec dual boot…

Now i want to describe, how to created dual boot on my media-box to run libreelec AND xubuntu. First i always install xubuntu on any computer i setup – always the same partition schema.

1. Partition is 8GB and labeled SYSTEM
2. Partition is 8GB and labeled SYSTEM2
3. Partition is 8GB and labeled SWAP
4. Partition is REST and labeled STORAGE

On the first 2 partitions i normaly install xubuntu, but i want to change the first to hold the image for libreelec. Boot into SYSTEM2 and download the latest Libreelec…img.gz. Than reformated the first partition as FAT32 and copy the image.

# gzip -d LibreELEC-Generic.x86_64-9.0.1.img.gz
# mkdir /tmp/le1; mount -v -o offset=4194304 -t vfat LibreELEC-Generic.x86_64-9.0.1.img /tmp/le1
# mkfs.fat -F32 -v -I -n 'SYSTEM  ' /dev/sda1
# mkdir /libreelec; mount /dev/sda1 /libreelec
# cp -a /tmp/le1/*  /libreelec/.

Now create a new grub-boot-option, to boot SYSTEM partition. Therefor create the file: /etc/grub.d/40_libreelec and run the command #update-grub

menuentry "LibreELEC" {
search --set=root --label SYSTEM --hint hd0,msdos3 
linux /KERNEL boot=LABEL=SYSTEM disk=LABEL=STORAGE quiet
}
menuentry "LibreELEC debugging" {
search --set=root --label SYSTEM --hint hd0,msdos3
linux /KERNEL boot=LABEL=SYSTEM disk=LABEL=STORAGE debugging
}

The basic configuration on STORAGE is automaticaly created on first boot…
