MX linux is in another drive and that's how I get it to run , when I run sudo update-grub it updates correctly , but it does not appear in boot options in bios.

If using MX Linux's GRUB,

At MX Linux, edit /etc/default/grub

Make sure you have the following settings

GRUB_DISABLE_OS_PROBER=false

Then execute the following command

sudo update-grub

========================================================

Alternatively, you can put the setting in the /etc/default/grub.d/ folder

Example: Execute the following command

sudo mkdir -p /etc/default/grub.d

echo 'GRUB_DISABLE_OS_PROBER=false' | sudo tee /etc/default/grub.d/os-prober.cfg

Then execute the following command

sudo update-grub

I don't know why the grub installation fails in your environment.

Maybe you can refer to the precautions I mentioned in another discussion thread #95 - dual boot.

Alternative

The default installation program provided by AnduinOS is ubiquity.

I provide another method here to install AnduinOS through calamares.

This is just an experimental method for your reference.

It's not guaranteed to work for your environment. You can experiment and see if it works.

Please refer to the following steps.

The current settings are only applicable to AnduinOS 1.3 series (Ubuntu 25.04 Plucky Puffin)

Howto

boot from AnduinOS 1.3 series ISO

At AnduinOS Live System, install calamares and calamares-settings-debian

sudo apt update

sudo apt install calamares calamares-settings-debian

download calamares-settings-debian-adjustment-for-ubuntu

git clone -b ubuntu-25.04 https://github.com/samwhelp/calamares-settings-debian-adjustment-for-ubuntu.git calamares-settings

change work dir

cd calamares-settings

run install.sh to install calamares-settings

./install.sh

run to launch calamares-installer

calamares-install-debian

Next, we can follow the steps provided by the calamares graphical interface to install AnduinOS.
