An ISO installation gives you control over partitioning and the operating-system installer. It requires more preparation than using a prebuilt template and is available only when your virtualization type and provider configuration support it.

Check access and requirements
Back up all data that must survive. Obtain a trusted vendor ISO, required licence and suitable virtual-device drivers. Record the assigned IP, prefix, gateway and resolver details because a manual installer may not configure the network automatically. Confirm console access before changing the boot device.
01 Install a VPS operating system from ISO in Virtualizor
- Open the correct VPS management view. If you must add an ISO, use the approved end-user ISO feature and a trusted vendor download, subject to provider permissions.
- Open Settings > VPS Configuration. Select the installation ISO and set the boot order to the optical drive before the disk. Review secondary ISO options if drivers require a second image.
- Save the settings. Follow the panel requirement to stop and start the VPS so the virtual hardware change takes effect; arrange a graceful shutdown first.
- Open the HTML5 VNC console and follow the installer. Choose the correct target disk. Formatting or repartitioning destroys data on the selected partitions.
- Set networking from the assigned service details, create administrator credentials and complete the installation. Install supported VirtIO or guest drivers where required.
- Detach the installation ISO, return the boot order to the installed disk and perform a controlled restart.
How do I confirm the ISO installation boots from disk?
Confirm the guest boots without returning to the installer. Test network reachability, remote administration, security updates, storage visibility and the intended application. Keep the console available until remote access is proven.
Resolve setup problems
If no disk or network adapter appears, check the required guest drivers before changing device types. If the machine loops back into installation, inspect its ISO and boot order. Ask support about missing ISO controls rather than using an unsupported image or guessing the assigned network.
