Ubuntu Installation :: GRUB Boot Menu Not Showing After Natty Update?
Apr 28, 2011
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?
I 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 upgraded to Natty yesterday and my system boots into it ok but I don't get a grub menu (and so no other options like recovery mode which I really need right now). I tried purging grub and re-installing it on /dev/sda but still no joy. Here's the info from the Boot Info Script. I've also tried uncommenting GRUB_GFXMODE=640x480 in /etc/default/grub but that doesn't help. How I can get the menu back?
Code: Boot Info Script 0.56 from 8 February 2011 => Grub2 (v1.99) is installed in the MBR of /dev/sda and looks at sector 1 of the same hard drive for core.img. core.img is at this location and looks for (,msdos1)/boot/grub on this drive. => Windows is installed in the MBR of /dev/sdb .....

I have dual-booted Windows XP and Ubuntu. Because Ubuntu 10.04 doesn't have the required proprietary drivers for my system, I chose Ubuntu 8.04. The installation procedure went well, the drivers are there, everything's perfect but... there's a problem with the GRUB menu that appears just after launching my laptop.
When I first installed Ubuntu it showed Ubuntu (and some letters and numbers), another instance for recovery mode, some memory test lines (I guess there are two of them) and Windows XP.
But after I used the software updater in Ubuntu (to make it up-to-date), the grub bootloader shows two more lines - and those are the same as the first two - Ubuntu (with some letters and symbols) and Ubuntu recovery mode.
Why are those duplicates there? I've never installed another Ubuntu OS on my PC. Because at the moment I have two Ubuntu and two Ubuntu recovery mode lines .
i have lucid lnyx installed as my main system and added natty on a seperate drive. after installing, the new grub detected lynx & i was able to boot into each without any problem. after doing some tweaking on natty (changed run level), it didn't boot properly so i reverted to the old config via rescue disk. after rebooting, the old grub menu didn't show & it loaded lynx automatically.
i tried the suggestion from another post changed the hidden menu and updated grub but it didn't detect natty (below).

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 have install ubuntu and windows in the same computer in their own partition. I think that I have remove something while I was reinstalling some wireless stuff using synaptic. When I launch the computer I get the dual booting but only with memory test and windows. I have the ubuntu installation cd. What can I do to get back the dual booting with the facility to launch ubuntu.
I am not able to see the existing windows OS already installed when the machine is booting.When the machine boots up I see a blank screen and it boot directly into Ubuntu.Here is the results file I have collected by running the tool:Boot Info Script 0.55 dated February 15th, 2010============================= Boot Info Summary: ==============================

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).
I installed 11.04 after Windows 7. when the GRUB boot menu starts up there is an option for Win 7 boot but it will not boot windows. When that option is selected the screen changes colour for 2 seconds and then reverts to the GRUB menu. Ubuntu boots fine.I downloaded the Boot Info Script and ran it, the results are

I 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 have a dual boot system: windows xp and suse(10.2). I had to reinstall windows(again). When I tried to use the installer, it kept reseting my partitions to 500gb+ to linux. Nothing I tried would let me put it to the way it was(50gb to linux). Repair install failed. Update wouldn't work. MSwindows in the grub boot menu disappeared. I tried reinstalling suse. The installer blocked any attempt by me to put the partitions back to normal. How do reset the windows and linux partitions(850gb windows, 50gb to suse linux)?
I installed Windows 7 and then Ubuntu 10.10 64 bits. The Ubuntu installation went fine but when rebooting a "check disk" appeared and since then my PC keeps booting directly on Windows. I tried all the GRUB reinstallation methods of the GRUB2 Community Documentation with the live CD but none worked.
Below is the output of the Boot Info script found on several threads.
Every time I update my kernel (today with 2.6.32-25-generic), I always have to manually run "sudo update-grub" or ells the new kernel does not show up on reboot??? Is there a config some place to get it back to automatic?
I have a computer that only runs ubuntu and have decided to put fedora on. I put fedora on the computer and made a new partition for it. When I turn the computer on, it logs straight into fedora not even showing me a grub menu. Is there some way that I can update grub so that it knows that ubuntu is also installed
Last week i decided to give the 11.04 alpha 2 a go on my laptop but compiz is currently too unstable for the OS to be of any use so I reinstalled 10.10. In doing this I deleted all partitions and started completely afresh. Strangely since then I have kernel image 2.6.38-1 at the top of my grub menu but if i try to boot it i get either a single blinking cursor or a kernel freeze. I cant find any reason why 2.6.38-1 should be in grub on 10.10.
removing it from the config files as im not used to Grub2 and have been told i cant just directly remove it from /boot/grub/grub.cfg.
After installing Ubuntu 10.10 dual boot with Windows 7(not inside Windows 7) and restarting I come to a blank screen with a blinking underscore.I assume the GRUB boot loader is missing or i installed Grub in some other partitions. Now i unable to enter in to Windows 7 OS.
I have a National Instruments gpib interface PCI card on my machine. It has been working up till now.The computer was moved when I was gone, and now at start up I get two alarm beeps from the motherboard speaker, no grub menu (hidden line is commented out and time out is gtr than 0).In the past I had to lock the kernel to 2.6.32-28.55.newer kernels broke the interface...although prolly foolioshly, I did allow other system updates.
Today when i browsing the net suddenly the system going HANG.....i will try to get the system monitor menu but in the menu list there is no icons. it is not displayed. then i will going to a warm restart....... after that the system didn't showing the grub menu.....it load the WinXP.......i will try two three times but the grub menu is not showing.....i am using the UBUNTU 8.10.
I've installed 11.04 on my laptop (dual boot with Win7). It goes through the grub boot menu and boots in ubuntu but displays ~inch wide band near the top, nothing else. I assume it is a display issue (it has an ATI mobile Radeon HD 3870 X2 card) but can't seem to resolve problem. I can boot into Windows via the menu. In the grub menu I can boot into the command line (grub>) but can't seem to make progress beyond that. Within this grub interface, it won't take terminal commands.
I used to be a pro at editing Grub's menu.lst file so I could have my menu look clean, simple, and easy to read. Now that I have set up 10.04 (Working beautifully now after a couple setbacks) the menu.lst file is no longer where it used to be (/boot/grub/menu.lst)
I have Windows XP SP3 running on my Desktop PC and wish to dual boot it with Ubuntu 10.10. This isn't the issue as I can do this and it gives me the GRUB menu but selecting Windows XP won't do anything - or so it seems How long should it take to boot into Windows from the GRUB menu?
I've got an old Dell Precision 670 which has a SCSI disk. I installed 10.04 and everything worked fine - I could boot into 10.04 from the GRUB menu. I later added an IDE disk and installed WinXP Pro on it.
When I ran 'sudo update-grub', Lucid discovered the IDE disk and added a WinXP Pro entry to the GRUB menu. Now, though I can still boot 10.04 from the GRUB menu, I can't boot WinXP - the screen goes blank, and I have to hit Ctrl-Alt-Del to restart.
For what it's worth, here are the results of using boot_info_script055.sh:
