Public bug reported: I downloaded http://cdimage.ubuntu.com/kubuntu/releases/20.10/release/kubuntu-20.10-desktop-amd64.iso.torrent and downloaded the ISO via Bittorent, wrote it to an USB stick and booted a very ordinary PC (which has a single SATA HD) from it. I chose install Kubuntu, chose use entire disk (guided) and successfully installed with no visible issues (chose download from Internet during installation and install third party stuff, but I believe this is not relevant). At the end when prompted I chose "restart" and when the installer a few moments later asked me to remove the boot medium and hit enter I removed the USB stick and hit enter. When the PC rebooted then the BIOS complained that no bootable device could be found. I did the install twice, both times with the same effect. I then installed Kubuntu 20.04 using the same procedure, and things did work fine with 20.04. I've successfully installed dozens of Linux distributions on that machine over time, and it's very unlikely to be a hardware issue. To me it looks like the Kubuntu 20.10 installer fails to properly make the disk bootable or install the bootloader. Prior to my installation attempt, some other Linux distro had already been installed, but I explicitly chose "use entire disk", so that should not matter.
