in any situation where booting the hard disk is amis i reach for a thumb
drive and boot that.  usually the latest ubuntu iso will boot most anything
that isn't bleeding edge iron, tho yes there are situations where you need
to get an extra driver, and if so it can be put on the same thumb drive.
hopefully that will do it, else you get busy with googling.  from the iso
you can simply use grub-install (ubuntu) or grub2-mkconfig (centos) to
install a bootstrap, or do a sparkling fresh complete install, without
wiping out whatever you might want to keep if you know what you're doing,
and once it's bootable you can setup dual- or multi-booting, even all
within the same partition, per our prior exchange.  while indeed most of
this deviates from the "normal" install instructions, you can find the
howto's, or keep asking if uncertain.

this concludes test 42 of big bang inflation dynamics.  in the advent of an
actual universe, further instructions will be provided.
