    Install Ubuntu Using a Small USB stick

    The Ubuntu ISO can be installed using the grub bootloader from a USB stick. Here is a Step by Step.

    • Download the Ubuntu ISO to the Downloads folder of Windows. (There are easier methods to install Ubuntu if you already have Ubuntu).

    • Download the mkusb ISO boot template: https://phillw.net/isos/linux-tools/uefi-n-bios/dd_grub-boot-template-for-uefi-n-bios.img.xz

    • Extract the image to a minimum 250MB USB using Rufus, Etcher, mkusb, Disks, dd, etc.

    • Edit the first menu entry of usbboot/boot/grub/grub.cfg as follows

      menuentry "ubuntu.iso" {
  search --set=root --fs-uuid 20EEA649EEA61756
  set isofile="/Users/c.cameron/Downloads/ubuntu-20.10-desktop-amd64.iso"
  loopback loop $isofile
  linux (loop)/casper/vmlinuz boot=casper iso-scan/filename=$isofile toram --
  initrd (loop)/casper/initrd
}

      Where 20EEA649EEA61756 is the Windows partition UUID.

    Reboot the computer to "ubuntu.iso" and install Ubuntu using "Something Else" as normal.
