Install a Linux OS from your ISO image

A custom Linux OS can be installed on a dedicated server by uploading an ISO image to DCImanager and booting from it. Windows can only be ordered at server provisioning time and cannot be installed this way.

Upload the ISO image to DCImanager

1. Open DCImanager

   1. In the Gcore Hosting Portal, navigate to Products/Services → Dedicated servers.
   2. Select the server and click To panel.

   DCImanager opens in a new tab.

2. Navigate to ISO-images

   In the left sidebar, select Templates, then click the ISO-images tab.

   
3. Upload the ISO image

   Click Upload ISO-image and fill in the form:

   • Name — enter a name, or leave blank to use the filename from the URL.
   • Select the source:
     • From the network — paste the direct download URL of the ISO file.
     • From the local computer — select a file from the local machine.
   • Location — pre-filled based on the server’s datacenter.

   Click Apply. The ISO image appears in the list when the upload is complete.

Boot the server from the ISO image

1. Start the ISO boot

   In DCImanager, go to Servers. Find the server in the list and click ⋮ at the end of its row, then select Load the server from the ISO-image.

   

   In the dialog that appears, select the ISO image uploaded in the previous section and confirm. DCImanager configures the IPMI boot device and restarts the server automatically.

2. Open and sign in to iDRAC

   1. In DCImanager, click the server name in the Servers list to expand its row.
   2. Under Connections, click Go to next to IPMI v2(lanplus). The iDRAC interface opens in a new tab.
   3. Log in using the IPMI credentials provided with the server.
3. Complete the installation

   In iDRAC, open the remote console to access the server display. The OS installer appears once the server has booted from the ISO image. Follow the installer prompts to complete the installation, then restart the server.
