How to Dual Boot Batocera / Ubuntu

Levellingup · 2018-07-28T13:18:41+00:00

Hi Guys I have installed Lubuntu as my main OS because my onboard, Intel graphics are better supported under Linux platforms. I am building a dual boot mach...

Ok, I understand.

I extracted boot.tar.xz in the batocera partition

I rebooted but batocera not showing in the grub2 boot menu

I have a 'Permission Denied' error when I update-grub2

I am not sure how to fix this?

If anyone has a solution that would be great.

For now, I am going to install directly to the HDD and try a dual boot later

Thank you for your help @nadenislamarre

note that the grub files under the BATOCERA partition are not required while there are not used while the ubuntu grub is used instead.

I've done a wiki for you :
https://batocera-linux.xorhub.com/wiki/doku.php?id=en:dual_boot_ubuntu_batocera.linux
it includes all including the ubuntu grub configuration file.

the wiki link is busted as well as other links on this thread. Would someone please send me some more information on this? I'm not very Linux savvy, however I am competent and have modded/edited many things prior.

This thread is the only one DuckNGo finds for this subject particularly

I just started using linux (mint) this week and was looking since the beginning how could I install Batocera in a logical partition. I just want to thank you Naden, it helped me a lot.

Hi there, I did all the steps (from the wiki) but Batocera doesnt boot. I can choose it from grub menu, also the partitions were created in the order described in the wiki (BATOCERA n, SHARE n+1) I have no idea what could be wrong. Could you please help me?

In my case, i had to change LABEL="BATOCERA" for LABEL="RECALBOX" in the 15_batocera file. Hope this helps

hello guys.
It´s possible dual boot in batocera and phoenix os?

joinski There is no "upgrades" folder on the wiki.batocera.org website, hence, running that command writes a 404 message on the 15_batocera file placed on /etc/grub.d
There is no "Grub" folder either.

okay, didn't check the address mentioned inside the wiki.
then this wiki-page seems either be outdated or false.

@nadenislamarre could you or one of the other devs have a look at the wiki-page?

Hi,
here is a solution grub2 on deb10.

/etc/grub.d/15_batocera

!/bin/sh
exec tail -n +3 $0

menuentry "Batocera" {
set root='hd4,gpt1'
        if [ x$feature_platform_search_hint = xy ]; then
          search --no-floppy --fs-uuid --set=root --hint-bios=hd4,gpt1 --hint-e$
        else
          search --no-floppy --fs-uuid --set=root B704-7B41
        fi
        chainloader /EFI/BOOT/bootx64.efi

}

disk ID comes from #blkid cmd

/dev/sdc1: LABEL="BATOCERA" UUID="B704-7B41" TYPE="vfat" PARTLABEL="vfat" PARTUUID="2fbddaca-d8e2-4977-9a97-cf103b31babe"

make sure to change set root='hdx,xxx' to match your HD setup

PS: it works when u have installed batocera on a dedicated HD.

The script is back online again https://batocera.org/upgrades/grub/15_batocera
ty to the batocera team

in more elegant way that mine

#! /bin/sh

BATOCERA_UUID=$(lsblk --fs --noheadings --pairs -o TYPE,LABEL,UUID |
		       grep -E '^TYPE="part" LABEL="BATOCERA" UUID="[^"]*"$' |
		       sed -e s+'^TYPE="part" LABEL="BATOCERA" UUID="\([^"]*\)"$'+'\1'+ | head -1)

if test -n "${BATOCERA_UUID}"
then
    echo "Image batocera found on ${BATOCERA_UUID}" >&2

    cat <<EOF
menuentry "batocera.linux" {
	insmod fat
        search --no-floppy --fs-uuid --set=root ${BATOCERA_UUID}
	linux /boot/linux label=BATOCERA console=tty3 quiet loglevel=0 vt.global_cursor_default=0
	initrd /boot/initrd.gz
}
EOF
fi

Hi, Iam trying dual boot, with LUbuntu and BATOCERA, I create the root partition for linux, for swap, then for BATOCERA and for SHARE. When I try to config the grub with the grub customizer I have no success to boot it.
The code you upload to inject grub already tested.
If snyone show me the code to insert in grub customizer I imagine I could make it works...
Thaxs!

I just recently got a dual boot with win10, linux mint and batocera to work fine. The instructions on the wiki for dual boot worked very well when i used them in Linux Mint 19.03. The partition table for me looked like this: 50gb for linux mint, 4gb share of fat32 named BATOCERA and 180gb ext4 share with the name SHARE. Extracted the boot.tar.xz in the batocera share and ran the grub script from the wiki. I then use Grub Customizer to change the order of the systems and everything works fine.

here is the code from grub customizer that is working for me:
insmod fat
search –no-floppy –fs-uuid –set=root AB82-AEE9
linux /boot/linux label=BATOCERA console=tty3 quiet loglevel=0 vt.global_cursor_default=0
initrd /boot/initrd.gz

where the UUID of the partition is in bold, change that to the one you have.

In linux it is easiest to find the UUID of partitions by
lsblk in terminal to find the correct partition and then
sudo blkid /dev/sda1 where sda1 is changed to the partition you want.

Hope this helps!

none of your codes works for me, but I still managed somehow. after I configure grub with:
sudo wget https://batocera.org/upgrades/grub/15_batocera -O /etc/grub.d/15_batocera
sudo chmod a+x /etc/grub.d/15_batocera
sudo update-grub
…
Image batocera found on AB82-AEE9
…

but there was no 15_batocera file, so:
sudo nano /etc/grub.d/15_batocera
and inserted the code frome: https://batocera.org/upgrades/grub/15_batocera

I combined your snippets to this boot sequence:

set root=‘(hd0,6)’
search –no-floppy –fs-uuid –set=root AB82-AEE9
linux /boot/linux root=UUID=AB82-AEE9 label=BATOCERA console=tty3 quiet loglevel=0 vt.global_cursor_default=0
initrd /boot/initrd.gz

bold = must be adjusted accordingly

Now Windows 10, Linux Mint an Batocera is working with Dual Boot.

Interesting, I have win10 on separate harddrive and another harddrive with mint + batocera. You ran the script from Mint and it ran ok but it did not show up in grub? Are you using GPT or MBR for the harddrives? I think your manual solution could be added to the wiki in case the automated does not work.

Good job getting it to work!

First I tried to pack Batocera on a separate HDD, like before Recalbox, where I flashed an HDD like a USB stick and then added it in Grub Customizer. But this didn’t work and led to hours of trying until I finally packed Batocera on the internal SSD to Win10 and Linux (MBR) and tried some time in the Grub Customizer. Now I will try to set up the HDD as an external drive for SHARE to have more space on the SSD again.
