Grub menu not visible on ubuntu 22.04 canonical

Question

I have created an ubuntu 22.04 server using the canonical market place image

I followed these steps:

1. In a text editor, open the /etc/default/grub.d/50-cloudimg-settings.cfg file.
2. Change the GRUB_TIMEOUT value to a non-zero value.
3. In a text editor, open /etc/default/grub.
4. Comment out the GRUB_HIDDEN_TIMEOUT=1 line.
5. Ensure that there's a GRUB_TIMEOUT_STYLE=menu line.
6. Run sudo update-grub.

However, even after rebooting the vm the grub menu is not visible, nor am I able to access it with Esc or Shift.

Thanks for posting your question in the Microsoft Q&A forum.

To resolve this issue, comment out GRUB_HIDDEN_TIMEOUT to disable it and set GRUB_TIMEOUT=5. After making these changes, verify that the modifications have been correctly applied by checking the generated grub.cfg.
