Hi @jtirelli, I believe that’s my case - my machine is pretty old and I get the same error as you mentioned. Unfortunately grub-pc-bin hasn’t solved the issue for me, since I’m still getting the following error:
Installing for i386-pc platform.
grub-install: error: install device isn't specified
Do you have any advice? Thanks!
