In the Ubuntu cloud images, it is not possible to get to the GRUB menu to edit kernel parameters. You need to edit the grub settings for that. There are two files you need to edit to make sure that the Grub menu will be accessible during boot:
- /etc/default/grub
- /etc/default/grub.d/50-cloudimg-settings.cfg
Example lines to edit
- /etc/default/grub
GRUB_HIDDEN_TIMEOUT=5
GRUB_HIDDEN_TIMEOUT_QUIET=false
GRUB_TIMEOUT=5
- /etc/default/grub.d/50-cloudimg-settings.cfg
GRUB_RECORDFAIL_TIMEOUT=0
GRUB_TIMEOUT=5
GRUB_CMDLINE_LINUX_DEFAULT="console=tty"
GRUB_TERMINAL=console
Run update-grub as root after modification, now after a reboot press Shift or Escape key during boot when you see the countdown.
