Thanks everyone for the help! Everything’s working now. 
Is there any update so that the new installer no longer requires manual partitioning the system?
I think i have a very similar issue here.
What made it finally work in your case?
I did not get it…
Welcome to the forum and hopefully to Fedora once the installer problem is solved. Several different issues have been mentioned: media test failures and problems after successfully booting the installer.
You need to provide more details, but posting in a old thread doesn’t get the same attention as a new post. You should create a new topic. Provide hardware details, which installer you are using, and exactly what doesn’t work. This will allow others with access to similar hardware to reproduce the issue.
Failures to verify the USB installer can be due to systems that change metadata but don’t alter the installation. If the downloaded .iso file passes the tests to verify it for both security and integrity, you may find the installer works even if the USB check fails.
Could you please let others know what you did to make it work? You had a problem, asked for help and suddenly miraculously it works, but how?
This forum is not only for somebody to get help to make his/her system run again, it is also about sharing info so others can benefit from it.
Thank you.
Yes
I had the same for Fedora 43 and simply skipped the media check. Fedora installed then without any issue, nor did any problems occur after the installed. It has now been in use for multiple months.
I installed the Everything ISO as a fallback, but it needs internet during install (Miscellaneous Downloads | The Fedora Project).
I’ll try Fedora KDE 44 once it’s out of beta and let you know how it goes.
The issue is that I run a dual boot setup on my PC with two separate SSDs, and the installer wasn’t recognizing that properly.
