Ubuntu :: Grub2 Menu Showing Sometimes With GRUB_HIDDEN_TIMEOUT=0
Nov 16, 2010
I'm experiencing an unusual problem. I have my grub2 configuration set to show no menu. However, sometimes it still shows and waits for input for no apparent reason. On a regular PC this wouldn't be much of a problem but on this particular machine I must make sure grub2 always loads Ubuntu without hanging.
I'm using Ubuntu 10.10 and the Grub2 installed package is 1.98+20100804-5ubuntu3.
My grub configuration is as follows (and I have ran update-grub after changing it):

After upgrading to 10.10 the grub boot menu stopped showing up. I made a custom menu in grub.d and update grub finds everything, but when I restart my system the boot menu never shows. I should have two kernels. How do I get the boot menu to show every time I restart my system?

When I originally installed Ubuntu 9.10 64 bit, I had the following operating systems already installed:
Kubuntu 9.04
Windows 7
Windows XP
Ubuntu automagically created a GRUB2 menu that offered all of these, plus of course itself, which was fine for a while.
Later on, I deleted and reformatted the partitions that had been dedicated to Kubuntu 9.04. GRUB2 has failed to keep up. Despite running "sudo update-grub" multiple times, the GRUB2 menu continues to show entries for Kubuntu 9.04.
How do I get rid of these obsolete entries? The partitions it was on simply do not exist any longer, so I don't know how GRUB2 is picking it up.
I had already edited my fstab file to reflect the new partitioning scheme, so I don't know where GRUB2 is getting the idea that I still have Kubuntu 9.04 installed.

I've just installed FreeBSD 8.1 on /dev/sda4 (FreeBSD slice), without installing the boot loader from FreeBSD (I've selected None when prompted for boot loader in sysinstall). Now I want to use my existing Grub2 from already installed Ubuntu 10.10 to boot FreeBSD also.
After some reading, I've added to the end of /etc/grub.d/40_custom:
After running sudo update-grub, grup.cfg file shows my new entry. The problem is that after restart, I don't see the new entry in the grub menu.
Another question, If i used chainloader +1, that means I need to have the FreeBSD bootloader installed also on /dev/sda4 right? For chainloading booloaders?
I didn't get to that step, I first want to see the entry in the menu.
Any idea what I might be missing/misdoing? (I also checked for blank spaces in the menuentry like the wiki for grub2 says)

I'm having an odd dual-boot problem. Briefly, I can't boot Windows XP from its entry on the GRUB2 menu. If I set the disk order in BIOS so that the machine boots off the drive with Windows XP, XP starts normally. However, if I boot off the Ubuntu drive, which brings up the GRUB2 menu, choosing the "Windows 7 loader" option (why it says Windows 7 when there's only Windows XP is another question!) just makes my system reboot.
It appears there's some problem with the way GRUB2 attempts to start Windows XP. I'm also wondering why GRUB2 thinks it sees the Windows 7 loader. There shouldn't be any Windows 7 anything anywhere. I once had a Windows 7 RC install on the same disk as Windows XP, but I wiped the Windows 7 system partition and reallocated its space as just another NTFS partition. FWIW, GRUB2 is installed on the MBR of the disk containing my Ubuntu install. Windows XP has a different drive all to itself.

I've accidentally installed grub 2 on a BackTrack4 usb install and I need some instructions to "convert" the old menu.lst so grub2 will automatically boot BT4. Here's the file contents:
Code:
# By default, boot the first entry.
default 4
# Boot automatically after 30 secs.
timeout 30
[Code]....

After a long night I managed to place my grub2 files on a separate partition on my hard disk. I am now able to edit my grub.cfg file directly (no more pesky update-grub commands) and I can create my own custom named menu entries in grub.cfg, the only problem I have encountered is in theming. I originally used burg to theme my menu, but found it to be a little unstable and erratic, so I have decided to use native theming options like font, color, and splash image.
But unfortunately, all the instructions for using these features invoke editing the 05 Debian script to make changes. As I no longer use this feature, I need to understand how editing the Debian script affects the grub.cfg file so I can manually create my menu. If you have themed your grub2 menu, please post the contents of your grub.cfg so I can get a feel for the what commands exist.

I've been following this guide [URL].... on creating a custom boot menu for Grub2 and I've run up against a wall. I made it all the way to the section on testing the custom menu but when I do, the new menu refuses to load. When I get to the boot screen I see the standard menu plus an extra entry at the bottom that will show what my custom menu will look like. When I select it though, it won't load. The screen blinks and remains on the main menu. I don't have the correct 'set' and 'search' lines in the 40_custom entry and I don't know how to correct them.

As a long time Red Hat/Fedora user, I'm quite new to the Ubuntu/Debian culture, and/or, to the Grub2 specific behavior.I'd like to see Grub2 system selection menu at every boot time even if I only have a single operating system, Ubuntu 9.10, on my hard drive. What should I do fot this purpose?

I am running Ubuntu 9.10 when I install new software it does not show up in the menu. I have to manually add it by editing the menu. Is there something that I have done that would keep it from adding things to the menu? I am new and not really sure if this is normal.

i am writing in Latex and tend to view my document in xdvik out of the vim editor. for some strange reason i suddenly dont have a menubar or scrollbar in xdvi anymore. i looked at the manpage which mentioned +expertmode 16 but this doesnt work somehow. in .xdvirc the expertmode is swiched off as well, but it doesnt make a difference if i change it there either. i tried reinstalling, which didnt work. I am able to get normal behaviour back from the commandline via the -q option. however i'd rather just have things back to normal

I am using 10.04 and when I start my system I don't get any boot menu to choose from. I am the only user of this computer and don't have to log in on start up but I would think that the boot menu screen would show up so I could use the recovery tool or change kernel if I wanted to. I have two other computers, and that is the first think that shows up on the screen when I boot them on. I am sure there is an adjustment that need to be made but not sure what to change.

I want to install more than on linux distribution on one computer (and the computer has Windows XP, too). How do you make a master grub2 installation that is in its own partition and that has entries that chainload different linux distributions that may have grub2 or grub?

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 upgraded my main box to Ubuntu 10.04 and everything runs fine, except for a problem with grub: I can't modify the boot menu in any way, I'm stuck with what grub2 thought was the optimal setup at installation time (and it got it wrong, btw). The current boot menu lists:
- my older 9.10 install in sdb2 (one kernel)
- legacy windows XP install on sda1
- my even older 9.04 install in sdb1 (two kernel versions)
- my new install in sdb3, with only one kernel (the one coming with the distro CD)
I tried anything I could think of to modify this menu:
- modify the /etc grub config file then running sudo update-grub
- using a specific app (system manager? don't remember its name)
- upgrading to the latest kernel
- removing and reinstalling grub
to no avail: the menu is still there in the above form, and I have to manually select the 10.04 (old) kernel by hand every time I reboot.

As it stands right now, Grub2 seems to generate menu entries in this order (for my pc)
Ubuntu 2.6.32-22
Ubuntu 2.6.32-22 (recovery)
Ubuntu 2.6.32-21
Ubuntu 2.6.32-21 (recovery)
Windows XP
How can I make it so that Grub generates entries in this order
Ubuntu 2.6.32-22
Windows XP
Ubuntu 2.6.32-22 (recovery
Ubuntu 2.6.32-21
Ubuntu 2.6.32-21 (recovery)
If you're wondering why I care about the order, its because I just installed Grub with an icon based theme. In that situation, it looks silly to have 4 Ubuntu Icons next to each other, and then the windows one at the end.

I recently (for about the third time) HAD to re-install Windows 7. It just wouldn't boot and unfortunately I have some proprietary software that I need to use. Anyway, this is the first time I've had to do so since installing Lucid (64bit, fresh install). My problem now is, when I re-installed Grub2 (using the same methods that have previously worked flawlessly) to recover it after re-installing windows, only windows shows up in the grub menu, showing options to boot to Windows on sda1 and another to boot to Windows on sda2.
I grabed a "boot info script" from Rubi1200 and this is what I got..
Code:
Boot Info Script 0.55 dated February 15th, 2010
Boot Info Summary:
=> Grub 2 is installed in the MBR of /dev/sda and looks on the same drive in
partition #1 for /grub .....

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.

Have recently installed 10.10 and have several other OS' installed, as well as other NTFS (non-OS) partitions. After a couple of updates, my boot menu shows about 8 entries, whereas I should only have about 4... How is this fixed in Grub2?
Have installed Startup Manager, and there seems to be no option here...

I'd like have some text written on my grub2 boot menu.
In legacy grub you could just add: title Foobar and you'd get "Foobar" displayed.
I tried: menuitem "Foobar" {} grub2, but it doesn't work. Any ideas how do you do something like that?
(Yes, I know writing grub.cfg by hand is not very smart. But I have a special situation: I wrote my own grub.cfg on a dedicated boot partition from where I chainload to other grub on other partitions. Those secondary grubs generate their grub.cfgs on the fly, so everything is OK )

I installed Win7 on a 2-disk RAID0 fakeraid. I then unplugged those drives and installed linux mint on a separate drive. I did it this way because if I left the drives plugged in, linux would jack up the fakeraid for those drives and make windows upbootable, and installing linux to the fakeraid itself is just too much of a PITA. So basically, this is the disk configuration, and there's no chance of me changing it.
Right now, I can boot into either win7 or mint by pressing F12 for the boot menu, and then selecting the drive the os is installed on. It would be nice if I could just add an entry to the grub menu for win7. I've used the menu.lst file before, but apparently all that has changed with grub2. I've checked out some of the grub2 docs and poked around in /etc/grub.d, but frankly, it seems to be orders of magnitude more complicated than it should be.

I've already read and tested the various guides for pasword portecting the menu items. What I need is a little bit different. I need to protect the whole boot menu so normal users cannot select any entry at all and only let the default entry boot.
