====== Run Ubuntu Installer from any GRUB-based system ======

So if I have a KVM VPS and the VPS provider doesn't provide Ubuntu 16.04 images nor mounting ISO images...

  - Get ISO from [[http://cdimage.ubuntu.com/netboot/]].<code>
wget -O/tmp/mini.iso http://mirrors.zju.edu.cn/ubuntu/dists/xenial/main/installer-amd64/current/images/netboot/mini.iso
</code>
  - Unpack the ISO to ''/livecd''.<code>
apt install p7zip-full
mkdir /livecd
cd /livecd
7z x /tmp/mini.iso
</code>
  - Reboot and spam <kbd>↑</kbd>/<kbd>↓</kbd> or hold <kbd>Ctrl</kbd> to enter GRUB menu
  - Press <kbd>c</kbd> to enter GRUB console
  - Enter one of the following code snippets into the console

<code grub xenial-netboot-install.cfg>
linux	/livecd/linux --- quiet
initrd	/livecd/initrd.gz
boot
</code>

<code grub xenial-netboot-expert-install.cfg>
linux	/livecd/linux priority=low ---
initrd	/livecd/initrd.gz
boot
</code>

<code grub xenial-netboot-rescue.cfg>
linux	/livecd/linux rescue/enable=true --- quiet
initrd	/livecd/initrd.gz
boot
</code>

<alert warning>Use netboot ISOs only! Otherwise, the installer will complain not mounting the CD.</alert>
