I have an ISO that lives at /temp/simp.iso and I want to install this software on CentOS 7.

Here is my current /etc/grub.d/40_custom file:

menuentry "install SIMP" {
    set isofile="/temp/simp.iso"
    loopback loop (hd0,1)$isofile }

Then I run grub2-mkconfig -o

Nothing happens on reboot and the software is not installed. What am I missing?

  • What software are you trying to install? Why do you need to do it at boot and not from within the OS? – Michael Prokopec Feb 19 at 23:39
  • I am trying to install SIMP (simp-project.com) and the instructions say: "Install as follows: Boot the system using the SIMP ISO" (simp.readthedocs.io/en/master/getting_started_guide/…) – J. Tate Feb 21 at 10:42
  • Did my answer help or do you need more information? – Michael Prokopec Feb 25 at 14:08
  • No, all you did was copy the link I already provided to the docs... I also read the docs and my problem is that the system does not restart automatically and even upon manual restart SIMP is not installed. – J. Tate Feb 25 at 18:40

Burn the ISO to a USB, CD/DVD. Use something like dd if=/path/to/iso of=/dev/path/to/disk. Then just boot the system to that media no need from messing with grub, follow the installer, making sure to point it to the right drives and everything. From what I understand from reading the docs, the system should restart automatically. It should now be installed and you should change the default passwords.

To boot to the ISO: Go into the BIOS and change the first boot device to your USB, CD/DVD.
