Is There A Way Or Means To Stop The GRUB Boot Screen Window From Appearing Frequently Since It Appears Often Now Since I Have Did A Ubuntu Distribution Upgrade?

Hello. I have a question to ask you regarding my Linux Ubuntu v.11.04 64-bit operating system.

A few days ago, I performed a distribution upgrade for my Ubuntu v.11.04 64-bit to v.11.10 64-bit successfully. It seems very strange since I have done this upgrade that in more instances than not (It is completely random too.) that “GRU GRUB version 1.99-12ubuntuS” window screen appears frequently as my Ubuntu is booting/loading prior to the Ubuntu login screen. While I did a clean install from a homemade DVD-ROM of Ubuntu v.11.04 64-bit, I never had the GRUB boot screen window appear when booting/loading into Ubuntu v.11.04 64-bit as I recall. Obviously, something is now triggering the GRUB boot screen window to appear often which to my understanding is not normal. I just select the first highlighted entry in the GRUB boot screen window (already highlighted/selected by default), and Ubuntu v.11.10 64-bit boots and loads fine tot he Ubuntu login screen.  

Questions:

1. Why do you think this is happening regardless if you think or not the distribution upgrade may be the cause?    

2. Is there a way or means to NOT have the “GRU GRUB version 1.99-12ubuntuS” window screen appear  frequently? Please explain.

Please reply.

Thank you!

A Shift key held down triggers it to appear, so it sounds like you have some keyboards with sticky Shift keys.

@ Darr247 & anyone:

Hello. Thank you for commenting, Darr247.

I will say that I do not think I have a 'sticky' shift key. I tend to think it is something greater in scheme going on here, just can not figure it out.

I have a question to ask you and this could be related.... ...*IF* I have another operating system (like Windows 7 64-bit) 'as part' of my computer, that is it DOES NOT share the same booting, and each are installed on SEPARATE hard drives; COULD IT STILL BE POSSIBLE that Linux GRUB is detecting ANOTHER operating system on the computer and triggering the GRUB boot screen window to appear?  (Even though the are not connected in any way.)

Why I say this is that I see on the GRUB boot screen window a MemTest, a few other things, and then at the bottom, Windows 7 and Windows Vista bootloaders. Yes, even thought they do NOT share any booting, could it be that GRUB 'is detecting' some other operating systems like my Windows and trigging that GRUB boot screen to appear each instance now? It does have some logic to it.    

Your thoughts?

Please reply.

Thank you!

I suppose so, yes, especially if the drive containing the other OS was connected during the install.

IT, Stop Being Called Into Every Meeting

Highfive is so simple that setting up every meeting room takes just minutes and every employee will be able to start or join a call from any room with ease. Never be called into a meeting just to get it started again. This is how video conferencing should work!

Hello again. Thank you for your latest comment.

I tried something that I thought would stop that GRUB boot screen from appearing prior to the Ubuntu login screen. I thought I would disconnect all internal hard drives except the only one that has Ubuntu on it and see after a few attempts of rebooting Ubuntu this would stop the GRUB boot screen from appearing. It didn't. The only difference I see is that it automatically runs the highlighted selection on the GRUB boot screen which happens to obviously be the first choice in the list in about 3-5 seconds assuming no changes are ever made to the selections to the GRUB boot screen. Before, it use to hang indefinitely until the user hit the ENTER key at the GRUB boot screen I believe.

Is there some Ubuntu internal setting somewhere that has been set to ON to bring up the GRUB boot screen by chance at Linux Ubuntu startup? If so, where is it? If so, what do I need to do to it?

Please reply.

Thank you!

You want to peruse this page
https://help.ubuntu.com/community/Grub2
especially the part up to and including the
Configuring GRUB 2
section, where you'll find the description of the
GRUB_HIDDEN_TIMEOUT=0
configuration file line.

Note well that you don't edit the /boot/grub/grub.cfg file, or your changes will get overwritten the next time the update-grub script is run.

Rather, you want to edit the /etc/default/grub file.

And after you edit that file, you still need to run
$ sudo update-grub
or
$ su -
password: [Enter the root password]
# update-grub

Note the space between the su and the dash.

Hello again. Thank you for your latest comment.

Yes, your weblink and the section you direct me to indicates that GRUB has a program component called or referred to as "os-prober". The weblink also states, "The default behavior is to hide the menu if only one operating system is present." Yes, GRUB really keeps a handle of what operating systems are lurking on your computer even if the operating systems were clean installed 'indepedently' from each other. So as long as I keep my Windows 7 installed on my computer, GRUB will keep coming up unless I follow your direction in your latest comments to override that.

Your solution in injunction with your weblink answers my question/thread very well to tell GRUB to disble the GRUB boot screen. A very nice reference! Thank you!

Question/thread closed.

Thank you!
