I have Fedora installed and I want to replace it with Ubuntu without using a USB drive. I want to use Ubuntu because of less software availability on Red Hat.

  • It's unclear what you mean by "install Ubuntu on Fedora." Do you mean replace Fedora with Ubuntu? Install them in parallel (dual-boot)? Something else? – user535733 Dec 16 '20 at 06:00
  • Are you asking to replace your Fedora system with Ubuntu? You will likely need either a bootable USB or DVD in order to make this happen easily. –  Dec 16 '20 at 06:01

  • @karel: A lot of answers there, to keep the OP busy for quite a while, only I did not see even one answer that did not require a USB drive as the OP asked. – C.S.Cameron Dec 17 '20 at 05:14
  • @Pilot6 I highly doubt that there is another question on Ask about installing Ubuntu from Fedora without using a USB. At least I looked and could not find one. This is Not a Duplicate. – C.S.Cameron Dec 17 '20 at 05:20

Booting ISO from GRUB Menu

The method on this page should work for booting an Ubuntu ISO from the Fedora GRUB bootloader 20.04 booting .iso from GRUB menu No need for a USB here.

To reiterate:

  • Add the following menuentry to /etc/grub.d/40_custom:

    menuentry "isoname ISO" {
  set root=(hdX,Y)
  set isofile="/[path]/[isoname].iso"
      loopback loop $isofile
      linux (loop)/casper/vmlinuz boot=casper iso-scan/filename=$isofile toram --
      initrd (loop)/casper/initrd
}

Where (hdX,Y) is the disk and partition the ISO is on, [path] is the path to the folder the ISO file is in, and [isoname] is the name of the ISO

  • In Terminal run:

    sudo update-grub

  • Reboot and select Ubuntu from the grub menu. Install as usual.

  • Please let us know how this works for you.
