Kde and Fedora booten dualboot

Hello,
I can’t install fedora alongside windows and kde neon. I get a message. I’ve attached a screenshot of the message.
My goal is to have windows and kde neon and fedora on the computer through a dual boot.
In addition to kde neon and Windows, I was able to install Zorin and LinuxMint and Deepin together without any problems. I could choose between all 5 operating systems in the boot menu. Now I only want Windows and kde and fedora. Only these 3 together, but the message in the screenshot appears and the installation of fedora is not possible!!! Can someone help me, what’s wrong??? Many thanks

You probably really want to also seek assistance with this on Fedora’s forums, since this isn’t related to KDE or Plasma at all.

At the very least, you will have many more eyeballs with experience with this distro, as not all of us here will have experience with Fedora and its Anaconda installer.

Thank You… yes i will try it in Fedora forum… thank You
