So I get the common Installing Boot Loader getting stuck in trying to install Fedora KDE. I see all over the internet that this issue has been with us forever I see mentions going back to Fedora 34 at least. I am a recently retired Software Engineer and I understand that Red Hat does not give Fedora priority since it is free, but this is something that should really be fixed and is unique to Fedora any other Distro installs just fine.
For reference I have just build a brand new PC with an ASUS ProArt X670 motherboard, several NVME SSDs 64GB DDR5 and an RTX3050 GPU. Wanted to try Wayland with a KDE distro and thought to give Fedora a go. The SSD is empty I am trying to install on and yes I am using the very latest BIOS and it uses UEFI.
F22-41 Workstation I haven’t seen the bootloader install step fail Legacy/UEFI on various computers. I don’t think the DE would matter but I tried F41 KDE and it installed too.
I’ve installed Fedora in UEFI to an ASUS PRIME-X470 PRO somewhere in 30s but don’t recall any issues or needing to do anything special. I’m not too sure what to suggest.
Maybe you try different way to install. Anaconda will fail in case that is not properly set.You not giving any feed back how you try to install example automatically choosing partitions or custom and witch sdd you chose etc …
While installing you can access logs by switching to consoles usinf ctrl-alt-F2, ctrl-alt-f3, (I cannot recall how many consoles).
I would hope there to be errors on one of them.
Also one of tbe consoles should give you a bash shell where you can run commands to explore the system and its process to see what is going on.
Oh and check your BIOS settings, does it have any windows only mode?
Maybe blocking boot strap install?
I have the same motherboard and have not had any issue with this.
After looking at logs yourself, post them or at least a screen shot here. It’s not clear what you’re saying is happening.
Then if it is a bug, you should file a bug report.
