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?
View 9 RepliesI'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):
Code:
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.
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?
View 1 Replies View RelatedI 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.
View 3 Replies View RelatedI 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.
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'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.
View 4 Replies View RelatedI am working with a acer netbook that I originally had WinXP installed on. I downloaded Ubuntu 9.10, transferred the iso contents to a bootable USB drive and installed Ubuntu. I remember during the setup process that I made sure I chose the option to install on one partition. There is only one partition on my netbook with a small second partition as a swap.
After the installation process and reboot I noticed the grub menu would pop up every boot up giving the list of operating systems of which XP was included. I then ran the update manager and updated 9.10 with all updates. After rebooting the grub menu again showed but the option to choose XP was now gone.
Now everytime I boot up the grub menu shows. How can I modify grub so it will automatically just boot to the OS.
I just installed ubuntu 11.04 via wubi. the installation appears to have gone well but ubuntu doesnt appear as an OS choice when i boot up.
Its not a timeout issue as it is set to 30sec and i can see my other options (windows and a recovery option). the only thing i can think of is that my computer has a separate partition set up for recovery and i think that is screwing things up.
Here is my boot.ini:
My only guess is that since the recovery partition is the first partition that its causing problems.
I was messing with my msconfig trying to free up some memory then I realize when I restarted my PC it just boot directly to Windows 7 without prompting anything, although it should because of Ubuntu.
Then, I tried uninstalling Ubuntu and installing it again (hoping to fix the problem). It's alright for me to just reinstall Ubuntu anytime, I was just exploring it. This error pop up when uninstalling Ubuntu
Code:
For more information, please see the log file:
I searched the "file that was not specified" and it was there!
So, I can't boot to Ubuntu and I can't uninstall it either. What should I do?
I just installed Debian squeeze. I installed grub to the MBR. It uses Grub 2. Apparently I'm not supposed to edit /boot/grub/grub.cnf, but /etc/default/grub and /etc/grub.d. I looked at these and read The Readme as well as a tutorial at [URL]. I'm still not sure of what to do. When I boot up I get 4 choices: 2 for Squeeze and two for another linux distro. I would like to edit the print out I get when I boot up, as well as add the partition for XP which wasn't included.
This is /etc/default/grub:
# If you change this file, run 'update-grub' afterwards to update
# /boot/grub/grub.cfg.
GRUB_DEFAULT=2
GRUB_TIMEOUT=5
GRUB_DISTRIBUTOR=`lsb_release -i -s 2> /dev/null || echo Debian`
GRUB_CMDLINE_LINUX_DEFAULT="quiet"
GRUB_CMDLINE_LINUX="" .....
I have Ubuntu 9.10, PuppyLinux431 and Windows XP on a Toshiba laptop. I like Ubuntu, but the speed of PuppyLinux is addictive, so that was my default boot until I upgraded Ubuntu which included an upgrade to Grub2.
My problem: Grub2 doesn't recognise PuppyLinux. Using information from [url] I have made an executable file named 07_Puppy in /etc/grub.d and did update-grub from root. Still no luck. I can boot PuppyLinux from the grub command line using the following commands:
Just before grub displays the boot menu, I think I see a very brief message about a syntax error, but it's gone before I can read it.
Here is the contents of my grub.cfg:

Why Grub2 doesn't see Puppy and let me boot it from the menu?
My Grub2 boot menu includes:
Ubuntu, Linux 2.6.31-19-generic
Ubuntu, Linux 2.6.31-19-generic (recovery mode)
Ubuntu, Linux 2.6.31-14-generic
Ubuntu, Linux 2.6.31-14-generic (recovery mode)
Q1) I only really need the latest kernel, 2.6.31-19, don't I?
Q2) So how can I get rid of the two 2.6.31-14 entries?
I have two hard drives - (1) 80GB (2) 500GB: the 1st HD has 3 partitions (in that order) - Windows 7, Ubuntu 10.10 & Swap. the 2nd HD is for storage only, and has 2 partitions.
I did the following - I installed Windows 7 on the first partition of the 1st HD, it booted just fine. Then I installed Ubuntu 10.10 on the second partition of the 1st HD.
Windows 7 shows in the GRUB menu alongside with Ubuntu. Ubuntu boots just fine, but when I select Windows it simply restarts the computer and the GRUB menu shows again.

NOTE: The above proceedure assumes you already have a grub.cfg file. If you don't, create one in the /tmp/cdroot/boot/grub directory
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 am very new user to ubuntu and new to this community,first of all if i make anything wrong in this post please forgive and guide me,
My friend have a laptop which was running in windows 7.Last week he installed Ubuntu 10.04 Lucid Lynx.But after that boot menu is not showing and it is automatically booting to ubuntu.
So i pressed Shift key during boot and checked boot menu list,which is showing only linux OS ,Linux OS recovery mode and memtest86,No windows 7 option.
So I did following things.
Step1: Tried to find out the partitions using fdisk -l
2.So i tried to add a manual entry by editing the /etc/grub.d/40_custom file like below ,and changed the permission using chmod +x update-grub command
3.Run the update-grub command
But it is not updating the manual entry,The above update-grub command output showing the update-grub command not even entering into the /etc/grub.d/40_custom file because i put echo in that file in that ,and that also not coming.
When I first boot up. I get the GRUB command line. What happened to the boot menu? And I can boot up into my Windows partition just fine. But when I try the other partitions i get "Unknown file system" or when I try to boot into the other ntfs drive, I get "BOOTMBR missing", but yet it does not mean Windows, because i can boot that just fine. I can't find my Ubuntu partition. How can I get the GRUB boot menu back?

View 1 Replies View RelatedI bought a new NVidia Asus EN210 for my HTPC, but I can't get Ubuntu to install.
First I made a live USB disk of 10.10 with Unetbootin and when I choose the option of "try Ubuntu" it starts loading and then just hangs, still showing the menu of boot options. After this I tried Xubuntu on a USB disk. This one also starts loading but then just fails. I also tried XBMC Live. This one does show the Ubuntu 10.04 screen but then just shows a black screen.
After this I found a CD with Ubuntu 10.04, I think or it is 10.10, laying around in my room. I booted it and once I select an option from the install menu it starts to load, but then just gives a black screen with a flashing "-" sign.
The strange thing is, once I pop in the old video card, which is an ATI HD4350, my Ubuntu 10.10 Live CD on USB disk does work and it does get past the menu of boot options (in my second paragraph I describe how this isn't the case with Ubuntu 10.10 combined with my NVidia card).
i wiped my entire hard drive that had xp as its only OS. I freshly installed a Windows 7 ultimate and everything went perfectly. I then decided to install 10.4. I split the partitions correctly (i had experience doing this already with my laptop, which has xp/10.4). Ubuntu 10.4 install went flawlessly, except for one thing. Now when i boot up the pc, it goes straight into 10.4. I have tried holding shift during the start up to force the boot menu, and it just shows the Ubuntu 10.4 OS as choices. Any clue what i could do to make Win7 appear in the boot menu?

i cant boot to windows 7.
Windows 7 have 100 mb partition "System Reserved" the grub2 points to that partition but still windows 7 not loaded.

I went through so many post but I haven't found the proper answer yet hope you have an Idea1. Grub2 saves only Linux OS as last selected no Windows OS2.It is possible to boot into a cdrom (drive)?
