black screen after upgrade from stable version 18 to 21


I did an upgrade from Fedora 18 to 20 everything went well. After upgrading from 20 to 21 I got the black screen after reboot. I am stuck on it. Now I cannot even boot back to 20 nor 18, what can I do?

Welcome to LQ!!! Can you 'talk' to grub (boot menu choices)?
Do you get a shell prompt? # _ dmesg/journalctl cmd 'alive'?

Here's something for ideas on collecting info. &1more
&a general wiki: https://wiki.archlinux.org/index.php...roubleshooting

Here's a web-search, to gather ideas: fedora upgrade 20 to 21 failed|problems
(maybe add black screen, but a technical keyword on what broke would be ideal)

Let us know a bit more details. Best wishes.

Yes I can get to grub prompt. I tried to boot from previous stable version with no luck.

What exactly does it say, when "no luck"? (So we can tell what broke/gone)
Can you try boot repair .iso: https://sourceforge.net/projects/boot-repair-cd
(If it can connect to the internet, it gives you a url with tons of details, which you can just link here!!!)
