Ubuntu Installation :: Update My System Without Having Efi-grub Removed?

Jul 15, 2011

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?

Ubuntu Installation :: Grub Not On System After Hard Drive Removed

Jun 16, 2010

I have 6 hard drives that have 9.10 and 10.04 on them. Not as a dual boot, but some hard drives have different versions on them. When I have plugged the drives in a couple of weeks later, the grub is gone and system will not boot. I get like a grub 1.5 error and that is all the options I have. Does anyone one know why this happens? Nothing on the drives but the O/S to get rid of windows. All drives worked perfect until they were removed and installed later.

Ubuntu Installation :: GRUB Removed After Windows 7 Boot

Sep 1, 2011

I'm running Ubuntu 11.04 and Windows 7 on a Dell Inspiron. On boot I get the GRUB menu listing Ubuntu (+ old versions) and Windows 7. However, if I boot Windows 7 all is fine until I reboot. On this next boot GRUB is gone and Windows boots. Ubuntu is still there, I can get into using my live-cd and 'repair' GRUB. After that, on booting GRUB is back and fine (including Windows 7). Does any one have an idea how to fix the booting/GRUB thing more constructive?

Ubuntu Installation :: Partial Update - Ffmpeg To Be Removed

Aug 10, 2010

Just wondering if anyone else has this partial upgrade being offered to them: ffmpeg, libavdevice52, libpostproc51, libswscale0 are held back (grayed out) in Update Manager.

I only use Update Manager manager to see if there are any updates and then use sudo apt-get update, sudo apt-get-upgrade and sudo apt-get dist-upgrade to actually examine the updates as it shows if anything will be removed without anything to replace it.

And I know to never do a partial upgrade.

Update Manager displays "Partial Upgrade" with the files listed above grayed out.

I did use sudo apt-get-upgrade to install a few packages earlier that were safe to install and now -

sudo apt-get-upgrade currently gives this output:

The following packages have been kept back:
ffmpeg libavdevice52 libpostproc51 libswscale0
0 upgraded, 0 newly installed, 0 to remove and 4 not upgraded

Ubuntu Installation :: Option To Not Install Grub On Natty/11.04 CD Removed?

May 13, 2011

In previous versions, there was an 'advanced' button where you could select NOT to install grub. I can't find that in the latest Natty release iso's. Is it no longer an option? And if not, WHY? I find myself reloading Natty quite often on a test partition to play with various parameters in my attempt to get it working as needed. But I'd really prefer to have the option to no reload grub.

Debian Installation :: 8.3 And Windows 10 Dual Boot GRUB EFI Removed

Feb 3, 2016

I've been using Debian for a few years but always on dedicated boxes and/or VMs.

Finally decided to dual boot Debian and Windows on my main Desktop PC.

Installed as I normally would using, however this time using a seperate drive (one for the existing Windows 10 install and the other for Debian), Debian install detects that windows has an EFI partition and sticks an entry in there, which is fair enough, and everything working fine. Then I spent some time configuring all my software and set it all up just the way I like it. I've rebooted Debian a few times to check it's working correctly and it is.

The issue arrives when I reboot and load into Windows 10. It boots fine.

However after a further reboot GRUB no longer loads... and the machine just boots directly into Windows 10.

After doing some further digging into my EFI partition (and reinstalling various times) it would appear that after a reboot Windows 10 deletes the entry GRUB creates in my EFI partition after EVERY reboot.

Done some googling and most people advise turning off 'fast boot' in Windows as it locks certain partitions to facilitate the machine going into hibernation, only to find that it's always been turned off on my machine (I recall due to a driver issue with my graphics card this had to be turned off when I installed Windows 10).

I've found this article on the Ubuntu forums : [URL] .... however I've tried their steps and windows is still doing a hostile takeover of my EFI partion after a reboot!

Any way to stop Windows 10 from interfering with my EFI files after a reboot? (without doing the obvious thing and kill Windows off).

Ubuntu Installation :: Restore Correct GRUB Boot Order After Removed XP Drive

Mar 11, 2010

I have an old Dell Dimension 4500 that, until recently, had 2 hard drives. One drive is running Xubuntu Koala and the other was running XP. I had set up Xubuntu to run LVM.

After needing XP again for a small project I tried reinstalling XP, got disk errors, took the drive out to just have Xubuntu, and now when I boot I get "Error loading operating system".

I have tried restoring GRUB from a Live CD with no help. Everyplace I look on the net talks about restoring GRUB after installing Windows on another drive. I'm trying to get GRUB working again after removing the XP drive.

Ubuntu Installation :: Boot/grub/win7 - Testdisk/update-grub Method, But It Didn't Work?

Mar 4, 2011

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:

Boot Info Script 0.55 dated February 15th, 2010 [code]....

ls: reading directory sda6/: Input/output error

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

Debian :: Grub Settings Revert After System Update

May 18, 2010

I used the Debian Lenny (main, not testing) update manager yesterday to install some new updates. Took a few minutes and no problems but today I started up and for some reason my system wouldn`t load.The hard drive installer automatically sets hd1,0 as my Debian system when it`s 0,0. I had changed this but upon updating yesterday the system again has grub using the previous setting.

Is there any logical reason why a system update (not upgrade, just small update via update manager using only main files not testing or volatile nor backports) could or would change my grub settings back to the wrong ones? I haven`t installed anything else, the only change has been the standard system update so it can only be that which caused it, but why?

I'm relatively new to ubuntu. I have an IBM X31 type 2672. It was running

Ubuntu :: Grub2 - How To Remove Removed Kernels From Grub.cfg?

Nov 25, 2010

I followed the Grub 2 Basics steps to remove Grub 2 kernel listings.

However I'm stuck with 3 older versions that was completely_removed from Synaptic (kernel/headers/generic), but remain in grub.cfg.


Here is my current grub.cfg:

(How do I remove *.14 *.21 *.22 from my menu entries Ubuntu-tweak is not an option for me. I like it old-school or with the tools at hand.)


I considered changing permissions for grub.cfg, but update-grub and new kernels will revert my changes.

General :: Unable To Boot With Ubuntu And Windows 7 - Grub Bootloader Getting Removed

Sep 2, 2010

I have recently purchased a new laptop, which came with Windows 7 pre-installed. I immediately installed Ubuntu alongside it with a dual boot. At first it worked fine, but when I restarted after the first time I used Windows, I ended up with an 'Operating system not found' error. I was able to reinstall the Grub bootloader using an Ubuntu Live CD, which appeared to fix the problem, but the next time I loaded Windows 7 and rebooted, the problem reappeared I think the problem is that Windows 7, for whatever reason, is somehow removing or disabling Grub.

Ubuntu Installation :: GRUB Installation Froze During A Routine Update / Fix It?

Mar 17, 2010

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"

OpenSUSE Install :: GRUB Chainloading Removed Boot-flag

Dec 13, 2009

I had my BIOS complaing that there were no OS. (worked since releaseday of 11.2).

partition setup:

sda1 : primary : swap
sda2 : primary : ext3 : Kubuntu
sda3 : primary : ext3 : opensuse (flagged as bootable)
sda5 : logical
sda6 : logical

opensuses GRUB is primary and Kubuntus is chainloaded.

The problem occurred after I tried to boot kubuntu for the first time since I installed opensuse. Kubuntu didn't boot. so I probably set up chainloading wrong. No big deal, this I can fix.

The big problem was that after trying to boot Kubuntu no OS was marked as "Boot" in MBR. This is VERY strange. somehow the boot-flag is removed!

After setting the boot-flag (with a live-CD) everything works again. I can reproduce this.

I've tried to find answers but could'nt find any.

Is GRUB supposed to remove the boot-flag when chainloading? have I found a bug?

Ubuntu :: Removed Wine - Cannot Login To System

Jun 24, 2010

I was experimenting WINE in my Ubuntu machine. After a while I've decided to remove it. I uninstalled the application that I installed using WINE (Steam - Day of Defeat). And then I ran the following command:
sudo apt-get remove wine*
I checked (using tab) and only wine, wine1.2 and wine-gecko where there to remove. After doing this I shutdown my computer. When I turned it on again everything was fine until I had to pass trough the login page. I've inserted my credentials and then when I clicked in "Login" it appears a dark screen and then again the Login screen.

Ubuntu :: System Hangs Whenever Module Is Inserted Or Removed?

Jun 26, 2010

After the updates about a week ago I noticed my system was hanging (screen and mouse frozen, unable to switch desktops, trl+Alt+SysRq+B still reboots) frequently. Though sometimes the system would not hang but become extremely sluggish and unresponsive. I've been able to determine that the problems occur whenever a module is added or removed. I can cause this problem with such commands as:

sudo modprobe aes
sudo rmmod raid0

I've tried multiple kernels but the problem persists. I've run memtest on the system but no errors have been found. I wonder if this could be some other sort of hardware problem but I'm suspicious that this began after a set of updates. I've seen message such as this in the kern.log:


Jun 25 22:35:48 localhost kernel: [ 240.480059] INFO: task modprobe:2672 blocked for more than 120 seconds.
Jun 25 22:35:48 localhost kernel: [ 240.492925] "echo 0 > /proc/sys/kernel/hung_task_timeout_secs" disables this message.
Jun 25 22:35:48 localhost kernel: [ 240.506918] modprobe D 00000000ffffffff 0 2672 2650 0x00000004


I've tried using strace but that was not helpful. This is becoming a serious problem as I cannot load any encrypted volumes due to the inability to load the aes module. dpkg is currently in an interrupted state as the system hung when upgrading virtualbox-3.2 when it attempted to remove the modules. So my system is barely functional and I cannot see any way to fix things.

Ubuntu Installation :: Update GRUB On 10.04 Wubi?

May 12, 2010

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?

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 ...


So it says its updating menu.lst but there is still no entry for 2.6.32-23? Am I missing something?

Ubuntu Installation :: GRUB Is Borked After Last Update?

Sep 7, 2010

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:


Boot Info Script 0.55 dated February 15th, 2010

Ubuntu Installation :: Grub Update Not Available For Kernel 2.6.38

May 15, 2011

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.)
