Invisible GRUB menu

[thenewguy]

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?

I'm sure you didn't mean to double-post

No, I didn't. Sorry. I got an time-out error after the first "submit" and hit "submit" again to make sure it went through. Apparently it did.... both times.

if the install hosting grub2 is the only operating system on a machine, the grub2 menu is hideen by default. you can change this in the grub defaults file.
open the grub defaults file with a text editor:

Code: Select all

gksudo nano /etc/default/grub

comment out the following two lines like this:

Code: Select all

#GRUB_HIDDEN_TIMEOUT=0
#GRUB_HIDDEN_TIMEOUT_QUIET=true

save and exit, and run update-grub:

Code: Select all

sudo update-grub

the menu should now show for 10 seconds, before booting into helena

Thank you. I had figured out the lines to change in the GRUB defaults file, but didn't know to run "update-grub" afterward.
