Adding a CD/DVD ISO Image
VPS SSD and HDD virtual servers have a virtual drive that lets you attach CD/DVD ISO images.
The system only accepts ISO files that are available directly via a URL, without the need to log in, confirm anything, or retype a verification code.
The system contains many ready-made ISO images. If none of them suits you, add your own by following these steps:
- Log in to the Customer Administration ⧉.
- In the top menu, select Server services VPS SSD or VPS HDD.
- From the list, select the VPS to which you want to add the ISO image.
- In the left menu, select Add ISO CD/DVD.
- In the box Add ISO CD/DVD enter the path to the ISO file and confirm with the button Download.
You will see the progress and the notification that the ISO file download has finished directly in the Customer Administration.
Attaching and Detaching an ISO Image
Attach or detach a ready-made or uploaded ISO image by following these steps:
- Log in to the Customer Administration ⧉.
- In the top menu, select Server services VPS SSD or VPS HDD.
- Select the VPS to which you want to attach the ISO image or from which you want to detach it.
- In the box ISO CD/DVD in the service detail, select the required image and click the button Attach or Detach.
The attached image will appear immediately in the OS, just as if you had inserted a disc into the drive.
After a single soft reset (via the operating system or Ctrl+Alt+Del) the CD/DVD remains attached and the server will boot from it. After a hard reset, the CD/DVD is not attached, unless you use the button Hard Reset + Attach.
When working with a CD/DVD ISO, observe the following precautions:
- If you no longer use an ISO file, detach it. The system continuously removes files that take up space on the shared storage, and the server may be shut down during such cleanup.
- If you do not want to boot from the CD/DVD, detach it immediately after use. Otherwise, an accidental restart may cause the server to boot from the CD/DVD instead of the VPS operating system.
Booting from a CD/DVD
Before booting from a CD/DVD, connect the KVM Client.
After you add and attach the ISO image, you can boot from it after a soft reset, or after a hard reset.
Booting After a Soft Reset
If the operating system is responding and you can perform a regular server restart:
- Attach the CD/DVD in the administration using the button Attach.
- Restart via the operating system or with the keyboard shortcut Ctrl+Alt+Del.
The server will boot from the attached CD/DVD.
Booting After a Hard Reset
If you have no operating system installed, or the installed system is not responding and you therefore cannot perform a soft reset, select the required CD/DVD in the administration and click the button Hard Reset + Attach.
Common Problems
Common problems with installing from a custom ISO include:
Cannot read from the CD/DVD
Problem: The KVM displays the error Could not read from CDROM, Code 0003.
Solution: Send the command Ctrl+Alt+Del. For instructions on how to send the command, see the documentation of your chosen VNC client.
Frequently Asked Questions
How do I upload an ISO from my computer to the system?
Use any storage from which the file is available directly via a URL, without any additional authentication. Uploading an ISO from your own computer is only supported by VPS ON.
