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.
