Ask Ubuntu is a question and answer site for Ubuntu users and developers. It's 100% free, no registration required.

During 10.04 starts it does a filesystem check. For some reason that I want to figure out, but this is another question, the harddisk is mounted read only.

I would like to boot to a rescue shell, but the grub2 menu is hidden

I cannot change the grub default config, because I have read only access to the harddisk.

I will now try and manually mount the harddsik readable to change the grub option.

Is there a secret key combination to:

  • show the grub menu anyway during boot?

  • make the splash go away during boot and see the interesting console output?

EDIT:

The answer is to hold the shift key, after the Grub Message "Starting Grub" appears.

This is also a good article about understanding grub2 or switching form grub to grub2:
