Ubuntu Installation :: Edit GRUB's Menu To Offer A Choice Between The 2 OSes?
Mar 30, 2010
I installed Ubuntu 9.10 (desktop version) and it performs flawlessly. Now I want to add a second hard drive to the same box, install Ubuntu 9.10 *server* on it, and use GRUB to control which one boots.
Problem is, I'm a Windows pro but a Linux n00b. Should I disconnect the first hard drive (the one with Ubuntu desktop) before I do the server installation on the second (new) drive? Also, how do I edit GRUB's menu to offer a choice between the 2 OSes?

I installed Lucid Lynx in my p4:2.66 hz machine with XP sp3 pre-installed and the system booted just fine with dual boot option. Then I updated my Lucid. All updates were downloaded. But during update installation a power failure caused PC reboot. Again I started update manager and it gave me option for "Partial Upgrade". I did the same and it instructed me to reboot. The the real damn thing happens now when I rebooted, In the GRUB menu it showed only Memorytest options. I see no OS choice there, I tried to reinstall GRUB from live CD with mount options. And it showed no errors during the procedure. I rebooted but the same problem exists.

I'm currently running Lucid Lynx, which installed the Grub 2 Boot loader which it currently lists three different Linux kernels. My problem is this:
1. How do I edit the menu to either remove or comment out one or more of the kernels?
2. Can I remove any of the kernels I don't want, which files do I remove, and will doing so compromise my system.

Yesterday I installed on my laptop (an IBM Thinkpad T42) "virt manager" using the Synaptic Package Manager. I'm running Karmic.
As part of the installation, SPM had me reboot the computer (which is dual-booted with Windows XP, which I use less than 1% of the time). The new GRUB screen came up showing two new initial lines, the first 2 of the following 4 lines:Ubuntu,
Linux 2.6.31-19-generic-pae
Ubuntu, Linux 2.6.31-19-generic-pae (recovery mode)
Ubuntu, Linux 2.6.31-19-generic
Ubuntu, Linux 2.6.31-19-generic (recovery mode)
When I allow the default choice of the first line to prevail, Ubuntu boots up into a condition in which the Wireless Network Connection fails to open, and in which nothing I've been able to think of makes it open.
If, instead, I scroll down to the third line (which was the initial default choice line, i.e., the default choice line prior to the "virt manager" installation), Ubuntu boots up into a condition in which the Wireless Network Connection operates as usual, viz., immediately.
Scrolling down works, but it would be better, it seems to me, to return to the condition in which the current line 3 either becomes line 1 or else becomes the default bootup choice.
I've used SPM to uninstall "virt manager", but the 2 new intial lines in the GRUB options remain. I understand that with Karmic's version of GRUB, viz., GRUB-2, it is no longer possible to change the bootup menu choices easily.
how I can either eliminate the first 2 lines in my current GRUB screen, or make line 3 the default choice?

The system came with Windows 7 installed.
After installing Ubuntu 11.04 (Natty) with Unity, I installed Xubuntu 11.04. All three OSes could be seen in the GRUB menu and I could boot any OS of choice.
Then I installed OpenSUSE 11.4. I suspect it installed legacy GRUB on the OpenSUSE root partition. Thereafter, I was not able to boot Ubuntu or Xubuntu.
I have now used a LiveCD (system rescue mode) to re-install GRUB on the MBR. However, I can only boot Win7 or Ubuntu. Can't access Xubuntu or OpenSUSE.
The results of my boot-info file are as reproduced below:

I recently installed Fedora 14 on an old Dell server (Pentium 4). It works fine, except that it somehow includes an extra startup step, in which I have to choose between two different grub versions. Here is the screen I get:
GNU GRUB version 0.97
Fedora (2.6.35.11-83.fc14. i686)
Fedora (2.6.35.6-45.fc14. i686)
Press enter to boot the selected OS, 'e' to edit the commands before booting, 'a' to modify the kernal arguments before booting, or 'c' for a command-line. I always select "Fedora (2.6.35.11-83.fc14. i686)" because I presume it is the latest version. Is there anything I can do to automate the choice of "Fedora (2.6.35.11-83.fc14. i686)" and avoid this extra step? On another subject, I have already modified the custom.conf file to eliminate the login screen step.

my Setup is Fedora 14 x64 + radeon hd 4830 i've downloaded .run package from ati site with latest driver for x64 systems. installed it, but didn't edited grub.conf becouse i didn't understood anything there (probably didn't spent enough time to get things understand) Now i've lost possibility to enter my Fedora system. during boot it lost it's modern blue boot screen (with filling drop), it was replaced by standard old boot screen with triple-color stripe. after this boot screen monitor start blinking going on and off. and on last step i'm getting "Fedora 14 boot bla bla bla something" on screen. nothing works except Ctrl+Alt+Delete. system reboots showing successful daemons shutting sequence. How can i edit grub menu from initial grub screen is it possible to it's own 'e' option or 'c' from grub command line?

is it possible to edit Grub2 to hide the rectangular frame around the selectable OSes? Also, is it possible to hide the Grub 'title' ("Grub GNU 2 (1.97~beta4)" et cetera)?

I have Windows XP as well as Ubuntu in my desktop. I would like to temporarily disable XP for a month or so, so that One cannot see Windows XP appearing in the grub menu list or during the boot. Is there is any option to edit the grub menu?

machine boots straight to Windows, Grub2 does not display the normal boot menu choices. Therefore, not able to boot into Ubuntu 9.10.Perhaps someone could look at this Results.txt file and shed some light on what went wrong.This machine was working fine for a long time, then all of a sudden, it starting booting straight to Windows.

I have Koala with Grub 2, working fine. Just did some updates and now the boot menu is getting long, too many kernels. Want to reduce to the last two kernels plus Win XP, so got online and looked for instructions in English. News flash: Nobody seems to care about this issue, there is absolutely nothing to be found on it for Grub 2. There is a SIMPLE command for Grub, "howmany", in menulst. Menulst is not used in Grub 2, so that's out. OK I give up, after searching for over an hour for Grub 2's equivalent. Maybe someone here knows how it's done? IN ENGLISH please, not "sudo I am an intelligent BEGINNER. The Grub 2 page says: "GRUB 2 allows users to create customized menu selections which will be automatically added to the main menu when sudo update-grub is executed." Note the word ADDED. What about REMOVING? Does anyone want to bother themselves with addressing this issue? I read somewhere StartUpManager can do this. Application Finder doesn't show StartUpManager on my machine, and reading about it at [URL].. as it seems to be Grub-1 related. I don't get the impression it will do what I want for Grub 2. If it does, they should say so, right??
I could remove the older kernels, but would rather just edit the boot menu. I found this for removing kernels: Open synaptic, do a search for "linux-image" and then remove the older kernels from your computer. Removing them via synaptic will remove them from the boot menu as well. Keep the kernel you are currently using plus one older one you know works. To find your current kernel: uname -r OK so I open synaptic and do the search. It comes up with maybe 200 files, some of which start with linux-image, scattered throughout the list. Oh boy, let a newbie loose on this. Just select and delete them all, why not? I can't tell one from another, the only difference is a cryptic number that means not one whit to me. There has to be a better way!
I got brave after editing etc/default/grub and doing update-grub, which reported the kernels by number, which I had forgotten. Then went back into Synaptic and hit the 'Sort By Installed' divider, which brought all the installed kernels to the top, where they make sense. Then I selected the two lowest-numbered and shot them in the head. They are gone.

i have been running Kubuntu 10.04 on my primary hard drive, and i have a second 1.5TB HD that i use for storage. so shrunk the secondary HD partition and created a second 50GB partition and i installed Ubuntu 10.10 on it and told it to rewrite the mbr on my primary HD. Where i am at: i took the menu entry from my Kubuntu "grub.cfg" and the entry from my Ubuntu "grub.cfg" and put them in the 40_custom file. so now when i boot-up my computer, it shows both installations at the bottom of Grub2s menu list. with all the menu entries that Grub automatically adds.
What i would like to know is how do i make it so that the Grub2 menu only shows the entries that i add to the 40_Custom file and not the randomly generated list aswell.

This morning I had 10 updates for my system including a new kernel 2.6.28-19 During install I was asked a question as to which menu.lst to use. I was completely confused as there was no documentation explaining the choices, so I took the default, keep my current menu.list. I did that because I have a modification to my menu.lst having added acpi-noirq I was afraid I would loose that and not be able to boot. Anyhow I ended up with my same menu.lst without the new kernel. So it booted the old kernel 2.6.28-18.Where is some documentation to give one some idea of which of the about 8 choices to make? I can't be the first with this problem. I have another computer to undate that has a different mod to menu list.I would like to know the correct way to choose the proper choice. If I don't get an answer I will try to document in more detail the choices.
I got around the problem by editing menu.list and copying the entries for 2.6.28-18 and changing them to 2.6.28-19 Many folks might not even realise they were running on the old kernel.

9.10 has no menu.lst file and hitting ESC to does not bring up the grub menu. How can we set bootup options or boot an alternate kernel? I would really like to set the resolution at boot time so that my console (Ctrl-Alt-F5, for example) has 80 columns instead of 40. (What a stupid default, gigantic Commodore-64-like text!) It would also be nice if the Login screen could be set to the resolution that I want.
In previous releases, there were ways to do this. In 9.10, I haven't been able to figure out how.
Is there a document explaining all of the radical changes?

I had windows 7 installed on my system prior to the installation of Lucid Lynx. The boot loader for windows is installed in /dev/sda1. The main windows installation is in /dev/sda3 Ubuntu is installed in /dev/sda5.
The grub update has added a loader for windows 7 for /dev/sda3 instead of /dev/sda1. How do i change that to /dev/sda1 in grub 2.0 as it says that it is not recommended to edit grub.cfg in grub 2.0. I know i can add something in custom section but I am not a pro in linux hence i'm not sure how to add that

I had to followed this tutorial on how to Install ubuntu on my Toshiba Satellite M35X-S114. I am stuck on step 2 now. I used one of the options and was able to get Ubuntu Desktop 10.04 onto my laptop. But now on my first restart I have to edit the GRUB menu and change the boot option so I will no longer then the black screen when booting. Only problem is I can't get to the edit GRUB menu. I turn the computer on select Ubuntu to boot. A black screen shows up I hit e to edit then the Ubuntu loading screen comes up (The one that says Ubuntu and has the dots below it) That screen stays up for about a half a second and it goes back to black and hangs there.

The first is I seem to have 3 GRUB installs. So whilst I update the one from my live session, the change does not appear in the boot up menu. I had installed 10.10 from a CD into a different partition (sda6), but that will not boot, so I have just deleted this and done another grub install and update. The kernel I am using has just been updated from 10.04 to 10.10 too, and it is this that I use and the Grub I have been working on (sda5).
