Installing your operating system from an ISO

Posted by / Apr 11, 2016 / Categories: Getting Started

ISOs on KVM Virtualization

Please be aware that installing an operating system from an ISO is only available on our KVM platform. If you have an OpenVZ service, please order a KVM VPS if needed. It is not possible to migrate from OpenVZ to KVM, you need to order a new machine.


Be aware ISO installers are likely to overwrite your existing VPS data. Take a backup of anything important on your VPS as it may be wiped.

Please take a note of your network config before starting your installation. You’ll need to note down your IP address, subnet mask and gateway. These are configured automatically for our standard Linux distributions but if installing an operating system from an ISO you may need to configure your network settings manually during the setup process.

ISO installation is provided as-is and we cannot provide any support in relation to the operating systems themselves.

About ISOs

Here’s a little about ISOs from Wikipedia:

An ISO image is an archive file of an optical disc, a type of disk image composed of the data contents from every written sector on an optical disc, including the optical disc file system. ISO image files usually have a file extension of .iso. The name ISO is taken from the ISO 9660 file system used with CD-ROM media, but what is known as an ISO image might also contain a UDF (ISO/IEC 13346) file system (commonly used by DVDs and Blu-ray Discs).
ISO images can be created from optical discs by disk imaging software, or from a collection of files by optical disc authoring software, or from a different disk image file by means of conversion. Software distributed on bootable discs is often available for download in ISO image format. And like any other ISO image, it may be written to an optical disc such as CD or DVD.

In reality the name ISO is a bit of an anachronism, as nowdays with disk images and virtualization they have little to do with physical CD ROMs!

Our platform allows you to mount an ISO so it behaves like it was a CD ROM that is connected to your VPS. You can then boot from that ISO and install anything on your VPS. This means you can run a wide variety of operating systems on BHost.

Available ISOs

We have the following ISOs available to install. If your desired operating system is not present on this list, please log a ticket with support providing a URL to the ISO so we can make it available to you.


If you want to install your OS from an ISO, you should go into your services, and click “Manage Server” for the machine you’d like to configure.

On the CDRom tab, select the ISO you’d like to use, and click Mount:

cdrom mount

On the settings tab, change the boot order to ensure the CD ROM (ISO) is booted first, followed by the hard disk:

ISO boot order

Reboot the virtual machine and the machine will boot from the CD ROM / ISO. You can then follow the installation instructions for the specific operating system.
