Andrei, et al -- ...and then David T-G home said... % % ...and then Andrei Borzenkov said... % ... % % it signature. So TLDR - it sounds like core.img was overwritten on % % /boot/gub2/i386-pc. May be it was deleted when new file was generated but % % information in MBR was not updated. % % Oho! How interesting. BTW, there *is* a core.img file, but it's dated 10/17 after all of his trying and retrying. No idea how it looked right after failure :-( But that IS dated before I ran bootinfoscript and generated RESULTS1.txt yesterday ... % % Sooooo ... How do I fix that? I wonder if boot to rescue -> mount root % under /tmp -> chroot -> grub2 -magic -fixarg is what I need. [snip] Alas, # make chroot stuff # chroot grub2-install /dev/sda didn't work; I get a grub2-install: error: cannot find EFI directory. error and it dies. I dunno how to force it [new grub2 install] to be legacy and use that MBR that it [previous grub2] supposedly has. ARRRRRGH! :-( :-D -- David T-G See http://justpickone.org/davidtg/email/ See http://justpickone.org/davidtg/tofu.txt
