I installed fedora about a week ago in a quite messy installation (l was trying to double boot with windows 10 and accidentally ended up deleting some booting archives from windows). Booting and shutting down was always pretty slow (it took a few minutes) and it showed some errors, but everything worked fine until some days ago the computer freezed when shutting down (maybe due to some updates i made, but i'm not sure) and i forced it to shut down After that the computer hasn't turned on properly, it has shown some errors and freezed and now it just gets to the login menu and when i select my user the mouse cursor turns into the kde cursor and the screen just gets black except for it. I really don't know what to do, I still have the live USB and I would have no problem in reinstalling fedora if you pint me to somewhere where they explain me how to do it (remember that the last time i lost my windows). Any help is welcome, i want to be able to use my computer again, thank you.

PS: here are some images of the errors

UPDATE: I updated the images of the errors, now is way more detailed, the errors I get are:

Failed to start Network manager.
Failed to start login service.
Failed to start D-Bus System Message Bus.
Failed to start Avahi mDNS/DNS-SD Stack
Failed to start Bluetooth service.
Failed to start ModemManager.
Failed to start ABRT automated Bug Reporting Tool.

Some dependency fails related to ABRT and Network Manager

and a line that changes from A start job is running for Network Manager and A start job is running for Login Sevice while a timer goes up.

Also, I think KDE is not starting at all and Ctrl+Alt+F3 just shows a white blinking underscore.

Well, you should try to boot with older kernel to see if and that allow you to login back again

Sorry, I should have clarified that i'm almost a total noob in linux, I was just going to follow the installing guide until all the problems came around, so, i'm not sure I understand what a kernel is, how am I supposed to boot with an older kernel? It's my first intallation of fedora, I was not updating.

it might help the development process to kill the desktop sessionby pressing alt+crtl+F3 (root) (passwd) then run killall -ABRT (process name of the KDE desktop session) might help show the development team some useful info to improve KDE or fix a bug

Okay, even though it didn't solve the problem, this was pretty useful, I can't open the command prompt (alt+ctrl+F3), when I press those keys i just get a white blinking underscore instead of the thing that should be written. Anyways, I realized that by pressing Alt+T I can see the details of what's failing during the fedora start, so I've updated the error in the drive. Also I pressed alt+ctrl+F3 in a working computer with the same SO and DE and ran killall plasmashell and when I pressed ctrl+alt+F1 I was in the same sitution, so I guess KDE isn't starting at all.

Use this link and look atrecommended partitioning scheme. Here you will find the mentioned UEFI part. Try it with an automatic install via Anaconda, before you do it, free up space on the destination disk. If you shrink an NTFS partition, do it via Windows 10. I have an UEFI notebbok too, but there I have no troubles with Fedora. I hope it helps you.

I already did that and it worked perfectly for a few days until it broke (probably my fault for forcing a shut down) my problem is how to securely uninstall the fedora I already have installed to subtitute it for the new one

Do you read the Fedora Installation guide carefully? You have a problem with booting UEFI mode, if your Images of Errors are true. UEFI must be installed in a certain manner to boot without any issues. Look at the Fedora Installation Guide, there is huge part for using UEFI. Follow these instructions. Good luck.

uhm... are we talking about this guide ( ? I followed it until I got stuck because in Acer computers you have to do some extra steps, but now i'm re-reading it and I don't seem to find the huge part about using uefi, and everything seems quite similar to what i did, can you point me out to that part about uefi?

this link should take you straight to the section that describes the uefi and bios boot differences, and what you need to do.

I read all of that and it wasn-t similar to what i had to do at all, I asked here and I did what the answer said, anyway i don-t think that's the main problem because the pc boots until I try to login with my user and it was working well before
