I am running Fedora KDE 40 alongside Windows 11 23H2, (the PC in question is also sometimes used by a few other family members, which is the reason I still have Windows) When I tried restarting into Fedora today, everything appeared fine, I selected the normal boot fedora option in GRUB, and the normal loading screen showed up. to be then followed by the cursor appearing for a while before it simply disappears, the screen goes black & turns back on stuck on a screen which is completely black with a terminal-like cursor in the very top left, It will then stay stuck thet way until you forcibly turn off the power. This hasn't happened before. I tried a live boot and checked the partition... It dosen't seem any different than normal. One thing I did notice is that yesterday on the login screen the sleep and restart option where bugged out, but I wouldn't think that's relevant? Can anyone help. I'm not sure what could be happening.
EDIT: here are some pics of the logs, I still dont know why this happened or really what to do, I'm still fairly new to this
Wasn't there news of a Windows update breaking dual booting recently? Could be that?
Yeah but that broke GRUB and had a pretty specific error message associated with it. I don't think problems with grub look like what OP is describing (although I don't know enough to say for sure).
Anecdotally, I'm running a Fedora Atomic-based OS alongside Windows and that Windows update didn't cause any problems for me.
