Administrators Hervé Posted July 3, 2019 Administrators Share Posted July 3, 2019 Moved from "Installation Guides" to proper support section. Please make the effort to post in the appropriate and relevant forum sections in the future. There are existing guides for this model in our Guides section. Eg: Did you follow them?

Moderators Jake Lo Posted July 3, 2019 Moderators Share Posted July 3, 2019 Make sure you have Switchable Graphics enable for the installation. You can disable it once installation is done. Quote Link to comment Share on other sites More sharing options...
