A Librem Mini was running PureOS after years of using a Debian distribution of GNU/Linux... I used an USB live with the intent of installing on same "side by side" but something went wrong... Now it boots into grub rescue.
In an effort to figure out I successfully have now a clean installation running but still can not boot from original encrypted disk and when I enter the passphrase I can access files on it.
I include some relevant output, I hope. After many years of -- well, up till 1993 -- using VAX/VMS and again using GNU/Linux I ought to be more knowledgeable by now and ought to have been more careful -- as well as having backup before attempting the above.
