Ubuntu Installation :: Update-grub Not Working?
Jul 22, 2010
I have upgraded from 9.10 to 10.04 but I'm still using Grub1 as I came from 9.04.
Anyway, during the upgrade I kept my original menu.lst file when prompted as I have a Windows XP boot option that I wanted to keep. I have read that this means your kernel won't be updated - and indeed mine wasn't.
The new kernel files (vmlinuz-2.6.32-23-generic) are on my machine in the /boot directory. uname -r currently shows 2.6.31-20-generic.
From what I've read you should just need to run update-grub manually and it will install. However, I have done this but it isn't upgraded. It doesn't modify my menu.lst or anything.
Output for update-grub:
Searching for GRUB installation directory ... found: /boot/grub
Searching for default file ... found: /boot/grub/default
Testing for an existing GRUB menu.lst file ... found: /boot/grub/menu.lst
Searching for splash image ... none found, skipping ...
[Code].....
So it says its updating menu.lst but there is still no entry for 2.6.32-23? Am I missing something?

I have 2 hard disks. sda,sdb
In sda, I have 4 partitions, and I have windows 7 in one of the extended partitions [not in the primary partition].
In sdb, I have 3 partitions. 2 for storage, and 1 10GB drive for Ubuntu. Again, Ubuntu is not of a primary partition.
I had ubuntu 10.04 running on that for a long time. However, I wanted to reinstall ubuntu and use 10.10.This is what I did EXACTLY:Booted from Ubuntu install CD
Chose advanced istall
Selected sdb3 for Ubuntu
I installed GRUB2 on the SAME partition as Ubuntu aka sdb3 Installed then rebooted
I can boot into Ubuntu fine, but whenever I select Windows 7 bootloader from the GRUB menu, the screen goes black, and my PC reboots.
Boot Info:

I have tried the testdisk/update-grub method, but it didn't work.

When doing a routine update to GRUB, it asked me what drive/partition I want it installed on. When I clicked enter to pass the OK message, the update manager froze momentarily and then it passed the selection page, saying "Warning: Installing GRUB to a partition other than the MBR is not recommended"
How can I fix this?

I had a bad experience with 9.04 - I installed some recommended system updates, and the updated GRUB killed my installation (which is WUBI), not letting me boot.
I've now installed 10.04, and some updates have come through, one of which is GRUB. So I'm now looking at the "Configuring grub-pc" dialogue box that's popped up, and there's an option to "Continue without installing GRUB?".
What are the risks here? Is my 10.04 WUBI system going to die if I upgrade GRUB again? Or is it going to die if I don't upgrade GRUB?

I am dual booting Windows Vista and Ubuntu 10.04 with WUBI. (Windows works fine). When I updated Ubuntu from the update manager, it just gives me this error code from a JPG attachment I just added with this post. It keeps on saying that every time ubuntu boots up.Is there a Fix? I cant boot up to ubuntu at all...

Whilst I've been using Ubuntu for years now, I don't really do much at the command-line, basically because I don't *have* to (which, to me is the beauty of this OS!). However, the last update via update manager has rendered my dual-boot with Vista on an Asus laptop non-functioning (at least Linux). What happens is this: after the BIOS splash screen, it says starting GRUB and then, instead of a menu of current and recent Linux versions and the Vista option at the bottom (white text against colour background) it now just shows one line of the menu in magenta... the rest of the menu is black, but the arrow keys will show the other options. Hitting ENTER does nothing: the text line is replaced with a blinking underline which goes back to the text in magenta again when i hit ESC. I can't seem to ESC or SHIFT to GRUB's command-line prompt at all. I've boot to the LiveCD and ran a boot_info_script in bash: here is what that revealed:
Code:

I grabbed an old laptop (a Dell Latitude D600) and installed Ubuntu 10.10 from the CD.Straight from the CD, it worked fine, including a reboot. I then ran an update, and now booting gives me the following message:

After upgrading Maverick (perfect!) to Natty, I was unable to boot into anything. (kernel 2.6.38). However, through much PITA, I was able to boot into an older kernel. (2.6.35). I completely removed 2.6.38, rebooted, reinstalled it and ran update-grub. However, 2.6.38 is no longer available no matter how many times I run update-grub, and the only option left is 2.6.35. In my humble opinion, the Natty upgrade experience is rubbish. (blank screen, total PC hangs, boots into a blank screen with only a blinking cursor, NVIDIA official driver not working, bootable only into older kernels etc.)

I have an odd issue that someone has hopefully seen before or can provide a next step. Firstly, I installed Ubuntu 9.04 about 7 months ago and things ran fine. I then did an upgrade (via apt-get) to the 9.10 kernel: Current: Linux 2.6.31-16-generic #53-Ubuntu SMP Tue Dec 8 04:02:15 UTC 2009 x86_64 GNU/Linux
Still, I had a properly functioning system. I then decided to install selinux since I was interested in learning how to set it up and get familiar with it's security features. When I was installing it, it got stuck on the portion where it had to modify Grub. It got stuck in a similar point as the following:

I have been phenomenally unlucky with Ubuntu as seen my my post history and decided to dual boot.
I set it all up with a clean install, when I tried to load Windows from Grub the computer restarted. After much headache I managed to set it up correctly (when it wouldn't load from Grub I booted from the Windows CD and clicked on "Repair computer" and it finally worked).
Now I am having the same problem as before--I think my installed all the updates from Update Manager and it included a grub one. Now I can't load Windows from the grub menu: It goes to the Starting Windows screen and then reboots my computer. If I do it again it gives me an error message and an option to perform "Startup repair". When I try to do Startup Repair, the computer reboots after a few loading screens.
So I tried what worked before and put in my Windows 7 CD, and clicked on Repair Computer. BUT NOW it gives me an error message somewhere along the lines of system restore is not compatible with my installation of Windows, and to insert a compatible recovery CD. This is the ONLY Windows CD I have (legitimate copy).
Over the course of this migration experiment I have installed and reinstalled both operating systems 7-10 times total. I'd rather not do it again. My poor laptop is probably wondering what the heck.
I can't stick with Ubuntu alone because my wireless doesn't work with it, my grad school files are not completely compatible with open source software, and I can't play the games I'd like to. So I must have the option to at least dual boot into Windows.
When selecting Windows it restarts the computer entirely to the Compaq screen, not just to the Grub menu, if that matters.

I did the kernel update via Update Manager today. Unfortunately , after this , disaster happened whereby sh.grub> prompt appeared on screen.
I got no idea how to rescue or repair the grub. I installed Ubuntu 9.10 in my E: under Windows 7 partition and labeled as "ubuntu". It has dual boot capability.

I have Ubuntu 10, Linux Mint 10, and Windows 7 installed on my machine. Every time there is a kernel update, grub adds the new operating system as a new item in the boot screen, but it does not remove the old variant. The result is that more an more choices appear as bootable, but most of them will never be used. Now, how, in grub V.2, does one remove old stanzas that one no longer needs? It seems to me that one merely has to go to the boot directory of the particular system one is in, remove the vmlinuz, etc. for the particular kernal version no longer needed, and then run grub update. This should give one a new cleaner screen on the next boot. Is this right?

I have this strange problem on ubuntu 10.04 64 bit, that when running update-grub, it will only put the oldest kernel into the grub menu, despite the fact that I have recent kernels around as well.
in particular:
Code:
# update-grub
Searching for GRUB installation directory ... found: /boot/grub
Searching for default file ... found: /boot/grub/default
Testing for an existing GRUB menu.lst file ... found: /boot/grub/menu.lst
[code]...
I'd like to see the most recent kernels in the grub menu, with the most recent being on top.

I have a dual boot system w7 and ubunutu. When i had version 10.10 (i think) everything was working fine, the grub would select w7 as boot preference. I have, however just updated to 11.04 and i cant get the grub to change its order. I have tried using startupmanager and selecting the second to last one, as per tips and i have also tried all the options. I have also tried editing the grub file, i think its /etc/default/grub. i have also tried grub-customizer but again, this doesnt work.
I have noticed however that the options shown arent the same as the options when i boot my system. Im not sure whether i have got two GRUBS installed or something like that. I have also tried using boot-repair, however this just states that there is no GRUB installed, however as i mentioned, i can read the grub, and so can the programs.

I'm running Kubuntu natty on grub-efi-amd64. I've just received notification of a bunch of new packages to install, I believe part of it is a kernel update. When I click on "apply" a window comes up which says "Additional changes are required to complete the task". "2 packages to remove" lists "grub-efi" and "grub-efi-amd64". It lists 5 packages to install 3 of which are linux kernel and 2 of which are the bios version of grub.
How can I update my system without having efi-grub removed?

I used the update manager to update the kernel and whatever the other recommended updates were yesterday. I shut the computer down overnight and now when i try to boot into Ubuntu 9.10 i get a basic grub shell and when i try commands like "boot" it tells me there is no kernel loaded. I installed Ubuntu with Wubi so it is a dual boot system.
I've tried to access the Linux volume with a live OpenSuse 11 CD but there is no device to mount. It sees the entire hard-drive as if it hasn't been partitioned. I don't necessarily need to fix the installation. I just need to get my files back.

I recently installed Ubuntu (Karmic Koala) on a Dell Inspiron 1525 which already had Vista installed on it. The installation went just fine and I could boot into either Ubuntu or Vista using the Grub bootloader options. After updating grub through the update manager however, I can no longer boot into Vista and get an error message that says:
"Windows cannot start. A recent upgrade or hardware change may have caused this".
And below that:
File: \boot\bcd
Status: 0xc000000e
info: An error occurred while attempting to read the boot configuration data"
When I run sudo fdisk -l, I get the following:

Partition table entries are not in disk order. I have the Vista recovery disk but was wondering whether using it to repair the Vista bootloader might mess up Grub.

The update package popped up with some security updates. I downloaded all of them and then hit the restart button. Now all I see after the winboot load is the grub 'dos' screen. I can get to grub rescue but thats it. I was wondering if there is a way to download the missing files from somewhere and place them in the grub folder as I am dual booting with XP.
I have installed Ubuntu onto a seperate partition as well.

IBM ThinkPad X61
Windows Vista Home
Wubi Ubuntu Karmic
I tried to upgrade to Lucid Linx while in Karmic Koala but the installation process froze while doing something with "memtest86+". CTRL-C got it to unfreeze and finish the installation but on a restart when I chose the Ubuntu OS it kept restarting rather than booting. I decided to start fresh.
So I booted into Vista and uninstalled Wubi Karmic Koala and proceeded to do a fresh install of Wubi Lucid Lynx. The installation, including the reboot, went smoothly. However, when the Update Manager was installing software a new screen popped up saying this:
Window Content:
[Title:] Debconf on Ubuntu
[Message:] Configuring grub-pc
[Checkbox:] Continue without installing Grub? (unchecked)
[Help button: explains consequences of not installing grub]
[Back button] (greyed out)
[Forward button]
So I leave the checkbox unchecked and click on forward. Nothing happens. All the Update Manager windows remain the same and nothing changes when I hit the Forward button. The "Applying Changes" window is stuck at "Setting up grub-pc (1.98-1ubuntu6) ...".
Can I safely force quit the Update Manager installation? Why am I getting that message about Grub? I didn't choose anything like that.

Ubuntu's update manager recently updated the Grub menu.lst file. It let me decide if I wanted to keep my old menu.lst or the new one. After deciding that I was fine with the new one, I found out that I can no longer boot into Windows 7. I had previously edited menu.lst so that Windows would be at the top of the list, however, I didn't notice that this had put it into the automagic update area, and I realize now that I should have just edited what the default number was instead of moving around the entries.
Anyways, I can no longer access my Windows 7 OS via Grub, and I was wondering what sort of fix I can have for this. I've tried running update-grub, but it hasn't fixed the problem. The Windows bootloader is on the first partition of the only hard drive, as far as I can remember.

After lots of searching last night I noticed that over the last couple of days there have been quite a few posts of people receiving the error: no such device lots of numbers grub rescue>. I have a dual boot vista/ubuntu setup with ubuntu on my d: drive and windows on my c: drive and it happened to me last night. So after my freaking out when I received the grub rescue> error after updating somethings in my ubuntu install and restarting. Once the computer rebooted bam! error. after much freaking it only fixed itself by reinstalling the windows bootloader via the vista rescue disk I was wondering if there was a way to prevent this from happening again? will ubuntu attempt to "update" itself again?

Installed 10.04 on my daughters laptop from within windows Vista. All went OK but I had two boot loaders, i.e. turn on laptop and I would get the Windows loader asking if I want to boot in to windows or Ubuntu. Upon selecting ubuntu I would get the standard grub loader that I have on my PC. Did an update a few mins ago and it asked me to update grub which I did and as there was only one disk showing clicked forward. Now on reboot I have grub rescue prompt, no such device. Hard drive is a single 80 gig drive with windows on one partition and ubuntu in another. Have the live cd so can boot from that I guess. What do I do next?

I have Ubuntu 10.04 installed on dell inspiron 5150. Original installation was perfect. Wireless Internet worked right away. Screen resolution was perfect. One day, after a month or so, after original installation I got a notification that new updates are available. So, I installed all updates. At the end there was a notification: Update is successful, please reboot. After reboot I got a black screen with the header:
GNU GRUB version 1.98-1ubuntu7(I hope it's not a ubuntu version of windows blue death screen). I could install 10.04 from scratch, but I can not do it after every update.

I recently updated, and now when I boot it only goes as far as grub command line. There is no grub menu. The computer is a Dell Inspiron 8600 laptop with only Ubuntu installed -- no dual boot, no weird partition schemes. Originally installed Ubuntu 09.04 on this computer, upgraded a couple times and it currently has (had) 10.04.1 LTS running. The update should have upgraded from kernel 2.6.32-23 to 2.6.32-24. I can boot with a live CD and mount the hard drive. The drive seems fine, so it appears to be simply a grub config issue. I have to boot with live cd to get online to check for potential solutions. So I'm taking some notes on how to use grub.

With a bit of help from this forum I managed to install 10.04. The solution was to add i915.modeset=1 to the options when booting up from CD.Now I need to do the same in order to boot up from HD. I've opened /etc/default/grub and changed the relevant line to include the above option. But I need to run "update-grub" and it comes back with an error to the effect that it 'can't find a device for / (is /dev mounted?)Also, the boot menu only has ubuntu - no sign of windows in my intended dual-boot. What can I do?
