Step 1: Ask us to turn on custom ISOs
Custom ISOs are switched off by default. Until they’re turned on, the CD/DVD-ROM card only says No Media Available. Open a ticket with VPS & Dedicated Servers, tell us which server it’s for, and ask for custom ISO access. Once it’s on, a Custom CD/DVD button appears in the card.
Custom ISOs turned on: the Custom CD/DVD button
Step 2: Insert your ISO
Find a direct link to the ISO
.iso and doesn’t redirect, for example a direct link on the operating system’s official download site. “Latest” links and download pages often redirect, so copy the link to the actual file.Open the Media tab
Click Custom CD/DVD
Paste the address
https:// (it’s already filled in for you), for example dl-cdn.alpinelinux.org/alpine/v3.22/releases/x86_64/alpine-virt-3.22.2-x86_64.iso.
Enter the ISO address
Click Insert

The ISO is loaded
Step 3: Boot from the ISO
Restart the server
Open the console

The server started from the ISO
Set up the network by hand if needed
Step 4: Eject the ISO when you’re done
Shut the server down
Click Eject
Boot
Check Auto Configuration
Change the boot order
In the Boot Order card, click HDD or CD/DVD, then Apply. There’s no confirmation: a Boot Order task appears in the task log, and the server uses the new order the next time it starts.Troubleshooting

A failed insert in the task log
- Check the link is a direct HTTPS link to an
.isofile and doesn’t redirect. - Wait five minutes and click Insert again. If a backup or other maintenance was running, the insert can fail even with a good link.
- Restart the server, then try again.
- Use a different download mirror for the same ISO.
