Problems upgrading f35->f36 : At this point I can't get there from here

[Jonathan Ryshpan]

I have just upgraded from Fedora-35 to Fedora-36 using dnf system-
upgrade. The upgrade appeared to go without problems, but the system
has been extremely slow  since the upgrade -- programs take a long time
to start or respond, delays in typing, etc. There seems to be a great
deal of CPU and disk activity for no apparent reason

===> Does anyone have a suggestion of how to investigate?

For lack of a better idea, I decided to reinstall my system: I built
installation media using  Fedora Media Writer and started a re-
installation process. However the Fedora installer for KDE thinks my
system is BIOS based, while in fact it is UEFI based; so it wants me to
create a biosboot partition at sector 0 of the drive.

===> Does anyone have a suggestion of how to investigate?

Run a top (top, htop, itop, etc.) to see what is using so much cpu.
Run iotop to see what is using a lot of disk io.
Look in journalctl at both the boot logs, to see if there were
problems initializing, and at the latest additions to see if there is
something complaining incessantly about a problem.

An install will only use UEFI if it is booted in UEFI mode.  The fact it
won't install in UEFI mode is highly suggestive that you are not
actually using UEFI when you boot the install media.  Get into the
BIOS, and make sure that you are booting the install medium in UEFI.

You could also try another boot medium. I like to use the bare bones
system cd, as it is small, and so simpler. I think it is called server
on the Fedora download pages. That is what I am basing the above
observation on, as it will not install in UEFI if it is not booted in
UEFI.

From the system specs you provided, you should not be having any
problems with responsiveness.
