Unable to burn iso to usb

[droidus]

I used dd from here to burn the iso to the usb stick: Burn an ISO File - Manjaro. When I boot to it, I get this error message: “error: unknown filesystem. Entering rescue mode… grub rescue>”.

This can have two causes

1. an incomplete ISO (flawed download)
2. an incomplete write to USB (file system cache not flushed completely to USB)

The first can be remedied by verifying either the provided signature or the provided checksum file.

The second can be remedied in two ways

1. by syncing the package udev-usb-sync from the official repo. Remove the stick and repeat the write.
2. by running the sync command after the dd command finishes - then wait for the prompt to return.

Please see our tools manjaro-get-iso and manjaro-iso-downloader which is utilities intended to download and verify the ISO using a single flow.

The ventoy utility provides a tool to make an USB boot a raw iso-file stored on the stick - essentially meaning - no need for dd or other burning utilities - drag and drop the downloaded and verified ISO file onto the Ventoy partition in your preferred file manager.

The get-iso script can write directly to a mounted USB stick if so desired.

As Ventoy was mentioned, I trust you will find this useful:

[HowTo] Create a Ventoy USB to launch Manjaro (and other) ISO's

Ventoy A New Bootable USB Solution Boot with a Ventoy USB and ISO files are automatically listed in the Ventoy menu. Any ISO present can then be launched and booted directly. The obvious advantage here is that instead of constantly writing a Manjaro Installer ISO to a new USB any time you might need it, every ISO you desire can be stored on the Ventoy USB and launched the same way. A 32GB capacity USB would allow ample space to store several ISOs of your choice; an 8GB capacity USB might …

Ventoy is also my choice. Very easy to use. Once the stick is prepared, it is a simple copy of the ISO file to the stick.
The ISO will then automatically appear on the boot menu of the stick.

But it requires that the ISO is correct. Otherwise the same error occurs again. So my first solution would be downloading the ISO from a trusted site again and compare the checksum, before i am doing other stuff.

@Pille

downloading the ISO from a trusted site

And that would be via the Manjaro site itself;

Manjaro Image Downloads

Please, avoid downloading any ISO claiming to be an authentic Manjaro OS, if it comes from any other location.

Downloading via the official Downloads page will ensure your ISO is genuine.
