How to create bootable USB stick with Rufus?

[lacer]

Hi,

I followed instructions of some YT video, downloaded the latest Kubuntu iso, installed Rufus. Starting the stick writing, there´s an error message:
ISO has grub 2.14 but Rufus has 2.12
So I select the option to download 2.14. But there is no feedback if that worked or not. Booting from the stick I see it didn´t work.
And that´s where I´m stuck. What now?

Thanks

Meanwhile I'm a step further, using Ventoy instead of Rufus. Kubuntu now boots, but is stuck at the login screen. Alas, different topic.

Which kubuntu release?
You might have a bad download, or even a bad spot on the USB stick, so those are worth checking



You can verify the image;

But at the moment you need to get the checksum for 25.10 directly from the download server;

Here is the official ubuntu doc on using Rufus, which does mention that Etcher is preferred, and easier to use. Ventoy is great, especially if one has a larger USB stick. And it saves wear and tear on the sticks as well.

stuck at the login screen

Login screen, for an installed OS? There shouldn't be a login on the live ISO session.
