In this case, installing the bootloader failed (reported in a different thread) due to some internal problem,p.H wrote:There are no incantations or magic. The installer has a rescue mode which allows to reinstall the boot loader (but that will presumably fail until the failure cause is removed) or chroot into the installed system and do whatever it takes to install the boot loader.
not due to an io failure. So sure, retrying the installation would fail, and I still have a nonbootable system,
presumably lacking only a bootloader.
Is there a procedure - something like - put an emergency bootloader on a stick, then use it to boot
the system from the main disk?
