Automagically repairs a boot loader.
This is something I wish I had/knew about a long time ago. I've had bootloader misadventures that really stressed me out.
I'll accept this, even though it uses systemd.

As of 2016-03-28, the latest LiveCD is 2014-11-30.
I'll keep the boot-repair LiveCD on a USB stick.
\wget --continue https://sourceforge.net/projects/boot-repair-cd/files/boot-repair-disk-64bit.iso/download \dd bs=4M of=/dev/sdx if=boot-repair-disk-64bit.iso
It's Ubuntu-based. Bleh.

Problem: Slackware 14.1's LILO installation worked, for Slackware and Windows 10. However, I got some mysterious error when trying to boot my existing Lubuntu installation. My system used to use whatever GRUB Lubuntu had installed.
\sudo \add-apt-repository ppa:yannubuntu/boot-repair \sudo \apt-get update \sudo \apt-get install -y boot-repair && \boot-repair
Do it's recommended repair. Sit back, and watch the magic.
This is probably an extremely complicated piece of software, whose functionality ought to have been cooked into the major bootloaders.
I'll probably end up with a boot-repair bootable disk once I figure out all my USB sticks.
