Invisible GRUB menu

Postby thenewguy on Sat Feb 06, 2010 9:31 pm

When I turn my laptop on, I got a very brief text message which, I think, says "Loading GRUB". The screen then goes black for about two seconds. Then I see the Linux Mint logo. I'm new to GRUB2, but I think my time-out is set for 10 seconds (I haven't modified GRUB's config at all). So I'm wondering why the GRUB menu is invisible. It's not an issue now, but I'd like to be able to see menu before a problem comes up. Any suggestions?

Linux Mint is funded by ads and donations.

Question- are you dual booting any other OS's (Windows, another distro) or is Mint the only thing on your computer?

If grub only detects one OS, then it will hide the Grub menu regardless of the 'hidden' setting.

To check your grub settings on this, navigate to /etc/default/ and open the file called grub (it will open read only this way)
One of the lines (probably the second) will read
Code: Select all
#GRUB_HIDDEN_TIMEOUT=0

With the '#' at the front it means the line is commented out and is ignored.
With the '#' the grub menu is set to display
Without the '#' the grub menu is set to not show for the amount of time specified (0 is no delay)

If you only have mint you'll probably find that the menu is actually set to show- I believe that is the default.

Let me know if this is not the case

Yes, or hold SHIFT at boot to show the menu.
rtfm - read the fine manual...
