Public bug reported:
(Summary says it:)
Upgraded by dual-boot kubuntu 18.04 to kubuntu 20.04. After the restart,
dual-boot was gone, and it boots directly into kubuntu.
I guess it is a problem with grub, because the boot menu doesn't show. However,
the 'lenovo' shows trice, while it used to show once with 18.04; followed by
the grub boot menu.
I guess that the MBR was written into haywire?
