Install ubuntu 26.04 on laptop lenovo ideap with snadragon

Ubuntu Support Template

Ubuntu Version: 26.04

Problem Description

I tried to install Ubuntu 26.04 in a dual boot configuration on a Lenovo IdeaPad Slim laptop with a Snapdragon processor.
The installation went perfectly with the resolute ISO (May 4, 2026) from :

However, it failed during the reboot. I ran boot-info:

Ubuntu Pastebin

I can’t perform boot-repair within the installation.
I used a bootable USB drive with a boot-repair ISO, but it’s an am64 version and it doesn’t work. There is an arm64 boot-repair version :

but how do I create the ISO image from the source code to create a bootable USB drive?

Thank you for your help.

Honestly, you’re better off just performing a fresh re-install vs debugging post-install.

First - please download the ARM 64-bit architecture ISO from Ubuntu’s official desktop page or the official releases page. Never download from an alternate source as it is not best practice and can lead to other issues.

Second - use one of the following programs to burn the ISO to a USB drive & make it bootable:

• Balena Etcher
• Rufus

Once you have downloaded the desktop-image ISO, please reinstall over your existing failed Ubuntu partition and report back your findings! Cheers~

Hello,
As you suggested, I used the 64-bit ARM ISO from Resolute with a bootable USB drive created by the ARM64 version of Rufus.

The installation failed to start.

On another brand new Asus laptop with an AMD64 processor, the AMD64 ISO installation proceeded normally without any errors.

Thank you for your help.

On one hand, it’s odd that the installer wouldn’t let you boot and initiate the installation process on your snapdragon Ideapad.

On the other hand, happy to hear you got ubuntu loaded on a separate machine.

Are you going to pursue installing Ubuntu on the Snapdragon Ideapad?

I’ve been using Ubuntu for work and everyday life since 2008. A machine without Ubuntu is useless to me. For now, I’m putting it away in a cupboard because I think the community will find a solution. There’s a preliminary analysis on this page:

. If there’s no solution, the Snapdragon will be a gift for my children, who have never wanted to learn about Linux!

Have a good Sunday

No worries. I have been using ubuntu for just as long.

If it was me, I would install 24.04 instead of 26.

Nevertheless I understand your situation and perspective. Sometimes the juice isnt worth the squeeze.

Cheers!
