OCI - How To Configure Ubuntu Instances to Display GRUB Menu

edited Nov 20, 2023 4:41PM in Linux

Applies to:

Oracle Cloud Infrastructure

Ubuntu


Goal:

When connected via serial console – in both SSH, VNC, and OCI CloudShell options – the GRUB2 boot loader menu is not shown at startup in Ubuntu images. This prevents access to emergency mode access to the instance.

Solution:

IMPORTANT: The below steps need to be implemented while the system is accessible.

That is, they are not applicable if the system is already experiencing issues and requires access to single-user mode. If this is the case, please open a service request: https://docs.oracle.com/en-us/iaas/Content/GSG/Tasks/contactingsupport_topic-Open_a_support_service_request.htm

Howdy, Stranger!
