Bedrock V3000 lacks an integrated display adapter. Consequently, to install Ubuntu, users must connect Bedrock to a host PC using a console, facilitated by serial over USB.

This document describes Ubuntu installation process on Bedrock V3000.

Test setup

This installation process has been validated by SolidRun with the following configurations:

Ubuntu versions:
- Ubuntu server 22.04
- Ubuntu server 23.04
- Ubuntu server 24.04
Terminal software:
- Putty
USB flash disk: Kingston Data Traveler

BIOS Boot select

You need to choose your USB bootable device to start the installation.

Insert the USB media to the device
Turn on Bedrock
Repetitively press the DEL / ESC key to enter the BIOS setup
In BIOS go to -> Save & Exit -> <your bootable USB device> -> yes

Configure grub

At the grub menu (displaying "try or install Ubuntu"),Press ‘e’ to set the boot parameters.

You'll encounter a window resembling:

initrd        /casper/initrd

Remove the quiet parameter and change the entry that starts with ‘linux’ to look as follows:

linux /casper/vmlinuz console=tty1 console=ttyS4,115200n8 systemd.wants=serial-getty@ttyS4 —

Wait for the live USB to boot

might take some time for the installer to run, so just give it some time

Live USB settings

After live USB boots
Run sudo subiquity
- NOTE: On newer Ubuntu versions the installer might run automatically, so you can skip this step.
If you see a “waiting for cloud init” message, wait until it times out and opens the installer (could take some time since some services should finish starting in the background).
Proceed with your preferred installation settings and await completion
Wait until installation is complete
When prompted, remove the installation media and press enter
