launch a ISO?

@g7kdz-joe uploading the ISO to the root directory of your server won't allow you to use it the way you want to. You need to mount it in a very specific way.

Have a look at this tutorial - it explains all the steps you need to take:

Hello Joe,

The first step would be to find out if your Linode is using KVM or Xen for its kernel. If you are a new customer, it is most likely you are using KVM but it's always worth it to double check. You can read more about KVM and Xen virtualization technologies here:

https://www.redhat.com/en/topics/virtualization/what-is-KVM

https://www.linuxjournal.com/article/8540

To verify, check the naming convention of the block devices. Device assignments for Xen Linodes were labeled as:

/dev/xvda
/dev/xvdb
/dev/xvdc

KVM Linodes use the “sd” naming convention:

/dev/sda
/dev/sdb
/dev/sdc

If you’re currently running a Xen Linode, you can upgrade to KVM, or follow our older guide on Running a Custom Linux Distribution on a Xen Linode.

If you are running KVM, you can follow our guide here:

You can also find all of our supported operating systems on our web page.

Our guide on deploying a supported operating system can be found below. This can be done completely from the Linode Manager.
