I've got a HP Pavilion ze2000 with a fresh install of Ubuntu 12.10 and after I got my wireless working, (12.10 HP Pavilion ze2000 wireless doesn't work) I'm ready to tackle this GRUB menu issue. From a cold start or on reboot, I have to CTRL+ALT+DEL to get the GRUB menu to come up so I can boot. At first I would power off then back on to get it, but after a while I figured out that CAD works as well.

I've done sudo apt-get update and sudo apt-get upgrade so everything should be up to date (I think). This is my first Ubuntu install but I have played with a couple other linux flavors.

After the GRUB menu comes up, the machine will boot no problem.

Any ideas? Thanks.

I don't understand what do you mean with CAD. This happen only after a restart, right? – Lucio Mar 11 '13 at 3:44
CAD = CTRL+ALT+DEL. It happens when I restart and when I power on after having had the machine off for a while. – JB0x2D1 Mar 11 '13 at 18:21

I also had this problem, but since my machine is different and I am using Lubuntu 14.04, I didn't post here. For documentation purposes, the solution I found is this one:


Comment out these options:


Change this line to look like so:

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash nomodeset"
