Disabling and stopping packagekit in systemctl allowed me to update
packages without the system doing it.  I think if packagekit is updated, it
may reenable in systemctl.  I'm not positive about that.

I narrowed the packages I am having issues with down to grub2-*.   It is
updating to version 2.06.  I installed all other updates on Fedora 33 and
the system booted.  Then I installed 11 grub2-* packages and the system
booted into the grub command line menu.

Again this is a dual boot system that had windows 10 installed first.
Fedora is reusing the /boot/efi partition that windows created.  I don't
think that it is an issue with the hard boot sector, boot sector being
locked, or memory since when do a clean install of Fedora 33 from the
install media, it boots normally.  I have reinstalled about five times to
isolate the issue.
