Uninstall openSUSE Tumbleweed?

[lvdl1]

Hello,

I installed, just to try it out, openSUSE Tumbleweed KDE 20250625 on the same internal drive (SSD) where Fedora 42 was already installed.
When I reboot now, I do not have the choice between the two, but openSUSE Tumbleweed starts always immediately.
What to do to have the opportunity to use both OS (not at the same time !) ?
Do I have to uninstall openSUSE and install it on a external drive or … ? And how ?

Please, if you see a possibility to solve my problem, present the solution step-by-step : I am not an expert !

Anyway, thanks in advance for your reply.
Best regards.

Hello and welcome to the openSUSE forums.

When I understand you correct, you do not want to uninstall openSUSE (as the title says), but you want to have Fedora and openSUSE both in your Grub menu at boot to be able to choose between them.
When that is true and if you can change the title of this topic, better do so that it shows what you want.
