I'm fairly new to Fedora, so I don't know much (yet), I'm still learning.

That said, I tried upgrading from Fedora 38 to Fedora 39, it worked perfectly, I updated everything (including the NVIDIA drivers, yes) and everything was running fine, I did not delete the previous versions of Fedora from my laptop just in case.

Come today, a week later, and I can't enter Fedora 39. My laptop gives me a list of OS to choose from: Fedora 39, Fedora 38, and (sadly, because I need it for my job) Windows.

When I enter Fedora 39, there is just a black screen and the laptop doesn't proceed from there, however, when I choose Fedora 38 (or W11), I can enter without any issues.

So now the TL;DR:

Having Fedora 39 already installed, is there any way I can uninstall Fedora 39 completely while being on Fedora 38, and then reinstall? If so, how would I do it?

Thanks in advance for the help!
