You can easily reinstall the operating system using the SolusVM automatic reinstallation tool but note that this option will destroy all the data on your VPS.
- Login to your SolusVM Control Panel. 
- If you have multiple VPS’, select the appropriate one.  
- Scroll down and you will see a - Reinstalloption. Click it. 
- You will see a lot of options. Select the operating system which you want to install. For example, if you want to install CentOS 7, choose it.  
- Scroll down to the end of the page and click the - Reinstallbutton. A confirmation window will open, click- Yes.
It will show a message that the installation can take up to 10 minutes and also show an admin/root password. Copy the password on the notepad because you will need to access your VPS user account later.
