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:

To display the Grub menu hold down the Shift key until it displays.
