2. If you have multiple VPS, select the appropriate one.
3. Scroll down, and under the "settings" tab, change the Boot Order to "(1) CDROM (2) Hard Disk".
4. Now click on the "CDRom" tab and if the CD-ROM is already mounted, click on unmount and then select your operating system from list. Then click on "Mount".
5. Reboot your VPS by clicking on "Reboot" and it will show a confirmation window. Then click on "Yes".
6. Now quickly click on VNC without waiting.

8. It will prompt for confirmation. Click "Ok" or "Continue" and it will show "Security Warning". Accept it and click on "run".

You need to press any key on your keyboard when asked and the OS Installation/Reinstallation will begin. It may also show you an option like "Install OS", "Test this media".
