Hello, you could just edit the title in your previous topic
rather than creating a new topic.
And for creating Manjaro bootable USB, the easiest route (for me anyway) is using Ventoy just as @jrichard326 explained.
- Insert your USB drive in the pc.
- Download the Ventoy archive.
- Extract it to a folder.
- Go that folder.
- Fire up a terminal in that folder.
- Run :
./VentoyGUI.x86_64 - Enter password if needed.
- A window like below will be opened.

[1]. Select the appropriate USB drive
[2]. Press the install button. - Now close ventoy window.
- Copy your ISO file to the USB.
- Live ISO should be ready!
The best part is, you don’t have to install ventoy everytime you want to try a new distro. After installing ventoy once, you can just copy paste new ISOs to the pen-drive and boot from them!
