Ubuntu Installation :: New Kernel Updates Don't Show Up In GRUB Or Boot
Mar 9, 2010
I'm currently running Karmic 9.10 in dual boot with Windows 2000. My computer has automatically updated and installed kernels 2.6.31-17, -19 and -20 (They show up in Synaptic as installed).
However, the newest kernel choice in my GRUB menu is 2.6.31-16-generic (followed by -15 and -14). These all start without any errors.
Question: Why haven't the newer updates shown up in GRUB for booting purposes?
Could it be a question that I didn't answer correctly some time back about accepting or not accepting an update or change in GRUB?
How can this be changed? The new kernels do not show up in Start-Up Manager either.

I'm remote from my system and so have to wait 2-3 days before I can get access directly, but I've noticed that when the kernel updates automatically (or forced by me), the next reboot stops at the grub page awaiting confirmation of the kernel I want to boot. grub.conf doesnt seem significantly different from that of fedora (my previos distro for this machine) and even has the default lines and times spec'd, so I can't see what's holding it up. Any ideas how I can prevent this so I can have my system auto-updating the kernel AND safe to reboot remotely?

I dual-boot my machine and I want it to default to boot into windows so that whenever I restart the machine remotely from my home it will be able to get back into Windows (instead of Ubuntu).
The problem is that every time Ubuntu upgrades the kernel, I have to reset the default boot item of grub back to windows. This is because the grub menu loader uses positions i.e. 6 for default OS to boot. And when Ubuntu installs a new kernel it changes that order.
I am looking for a way to configure grub to remember its default boot item under kernel updates.

Possible Duplicate:Make grub keep its default boot under kernel updates.I have just installed Linux with my windows 7 pre-installed and i got it working fine. Since i use windows 7 more than linux, i would like to have "Windows 7" option on the top of "Linux" option.
"When i have turn on my computer, the first thing i see is an Option asking me whether i want to use windows 7 or Linux and there's a countdown timer below it which is 10seconds countdown and if i don't select it on time, it will automatically select the first choice which at the moment i've got Linux pre-set as my first choice."

I've been having a problem on my AMD based machine, 4cpu, gigabyte ga-ma78gm-s2h Mobo, 8GB mem, two 2 terabyte Sata HDs.One thing I've found is that any kernel after 2.6.32-17 has a randomness at boot time whether the system will completely boot or not.
For instance just today I downloaded and installed 2.6.32-24
It fails to boot (I've tried cold boot, warm boot).Running its repair also fails to completely boot.My experience is that if I keep trying it "may" eventually boot but I believe there was some change after 2.6.32-17-generic that's causing the problem.Because as with 2.6.32.23... which also fails to complete bootup many times... eventually my guess is that 2.6.32.24 will also boot "sometimes".But why does 2.6.32.17 always boot for me? Something changed and its not my setup.

I have installed ubuntu 10.04 64 bit in April and it has worked flawlessly. However, today I ws prompted to install Kernel updates. Now when I try to boot it continually cycles between a black screen and the NVIDIA logo.
Yes I have been using the nvidia drivers previously but without incident till now.
I have tried crtl-alt-f1 but this does not stop the cycling.

Basically I had windows 8.1 running on my fujitsu lifebook A532 laptop and wanted to dual boot kali linux alongside it, however upon installing the linux it deleted EVERYTHING! on my laptop, the grub bootloader only showed kali linux to choose from...
I then decided kali linux is too complicated for me and decided to delete everything and reinstall windows 8 again however I was surprised that my bios screen looks diffrent also I can not edit the boot sequence.
If I press f2 or f12 it takes me to a screen with a tab named Boot menu and its written on it debian and every time I press enter on it it takes me back to this same screen...
I can not boot from cd or usb!

I couldn't get 10.10 to boot (live or after install). I was able to install and boot 9.10 normally. Then I ran upgrade to 10.10 and I started getting the same problem trying to boot as with 10.10 disk. I found I could boot with 2.6.32 left from 9.10 but it will not boot 9.6.35 kernels. On a normal restart when automatically trying to boot the latest 9.6.35, I get this message before switching to an unresponsive black screen with no further hard drive activity:
GRUB loading
syntax error
Incorrect command
syntax error
error: file not found
[Linux-bzimage, setup=0x3400, size=0x420c50]
[Code]...
I have been searching for a solution and so far have not found anything that worked. I'm a pretty basic user so I'm not sure what is going on.

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 seem to have determined a few other things about my "only gets as far as a GRUB command line" problem:To recap, sda3 (GRUB hd0,2) is the main Linux partition; sda9 (GRUB hd0,8) is the boot partition.GRUB is 0.92.Installation was from an 8.04LTS live CD (at least, that's what the envelope says it is)/"/boot/grub" (i.e., "/grub" on sd9/hd0,8) contains a "menu.lst" file. I modified it (had to do a "sudo gedit" from a command line!) to (1) comment out the line that hides the boot menu, (2) change the timeout from 3 seconds to 90, and (3) add a menu line based on my succesful manual IPL of DOS.
It still boots to a GRUB command line. If I do a "configfile /grub/menu.lst," a boot menu comes up. DOS will successfully IPL, but Linux still gets a "no setup signature found," (ditto for "recovery mode"), which suggests either a bad kernel, or a kernel that's too big for the GRUB to handle.Why would it be finding its way to grub, but not finding the boot menu file?Why would the live CD come up just fine, yet the GRUB and kernel it installs fail?

I'm a very new Linux user, so speak slowly and don't use big words. I installed Karmic from the Live CD. It is the only OS in use on this system. I then upgraded to Ubuntu Studio using the instructions found on the wiki.
On bootup, I get a brief message stating "GRUB loading" and then the system automatically boots to the generic kernel. No GRUB menu is ever displayed. I would like the option to boot to the real-time kernel, but I have no idea how to edit the appropriate files. I've done a fair amount of reading on the subject, but I find very little information relating directly to the real-time kernel, and so I still feel like I'm too green to do it without messing something up.

I want to try out the realtime kernel to get my audio latency down. I have installed the realtime kernel packages according to the Ubuntu Studio preparation documentation here - I have also run sudo update-grubHowever, when I boot up, the realtime kernel option does not show up in grub2. The current kernel I am using is 2.6.31-17, but the only options in grub for it are -386 and -generic.
There is a previous entry of 2.6.31-9-rt which I had attempted to use previously (sometime last year) but if I select it, it doesn't even boot at all.I checked my /boot directory and there is no vmlinuz-2.6.31-17-rt file .... Which I am assuming is why it doesn't show up or add when I run update-grub ... But I am currently at a loss for how to actually get the 2.6.31-17 realtime kernel file and add it to grub2.

Is there a way to show GRUB 2 interface only if you hold ESC at boot? If I remember well you can do it with GRUB 1.

I got the grub loader to work finally. The problem is it does not always display at initial boot or a restart. I have seen the selection menu but it doesn't always appear. I have it set to point to windows so that my wife can hit enter when she gets a blank screen.
Below is the contents of my /etc/grub.conf file:

In order to use each OS I manually hav to go and change the "first boot device" option in BIOS setting and boot into required OS. GRUB doesn't show Windows in its boot menu.How can I make GRUB recognize Windows and boot into both OS using GRUB boot menu?

Over the past few days I have been trying to install an older kernel (kernel 2.6.28.1) on ubuntu 9.10 64-bit WUBI installation. I compiled, installed, and updated my grub for the kernel. When I reboot, the grub menu correctly gives me the option of booting into the older kernel but when I do so I receive the following error message:
error: you need to load the linux kernel first.
I am at a complete loss on how to fix this. I even downgraded grub but I still get the same error.

I installed it from a cd and it wouldn't work. (froze in the process). I then tried to install it through windows wubi and that didn't work (wouldnt boot) since I was unaware it was a known issue and thought it was me doing something wrong I uninstalled it,reformatted the hard drive and tried to install via a cd again this time it fully iinstalled but when I rebooted it tells me unable to mount drives and a shell will be shown.
in the end I have no files on ubuntu so I would like to clean up all reminance of the previous installs and be able to use a working install. since I have been installing and reistalling for the better part of 8 hours.Yexcuse the post sloppiness using my phone)

The update notifier displays as usual but it will no longer "show updates" either when double clicked or when right clicked and the option is highlighted. the other options in the context menu function as normal.
Code:
s7726@blackbox:~$ update-notifier --debug-updates
(process:3463): Gtk-WARNING **: Locale not supported by C library.
Using the fallback 'C' locale.
(update-notifier:3463): update-DEBUG: update_check()
[Code]...

I've had two students report a problem whereby Ubuntu does not show up as a menu option in Grub. Both systems used Wubi installations of Ubuntu 10.04 Desktop for x86 on Windows XP. In both cases, Ubuntu completed the installation process. Upon reboot, we have the options to choose between Windows XP and Ubuntu. However, once we enter into Grub, only the Windows XP option shows.

I have a dual-boot setup with Windows 7 and Ubuntu 11.04. Each OS is installed on a separate partition of one hard drive. I read that installing Windows after installing Ubuntu wipes out Grub, so I made sure to install Windows first. Unfortunately, after completing the Ubuntu install and rebooting, I see no sign of the Grub menu. I followed several sets of instructions for reinstalling Grub, and after running grub-update, it appears that Windows 7 was added to Grub, and after examining the grub.cfg file, it appeared that that was the case. Despite appearing to be installed perfectly once inside Ubuntu, Grub doesn't show anything at startup. No matter what I try, I can't seem to make Grub appear, and now I can't get back to Windows 7. Am I missing something, or should I try a different bootloader?

How can I uninstall grub? I have have dual boot between Gentoo and Ubuntu and I want to use the grub, that is on Gentoo partition, as its my main system. I would not care about it as it takes almost no space, but Ubuntu automatically restores its own bootscreen after updates. This is annoying... How to get rid of it?

Have just installed 9.10, again, many failed attempts previously.Cannot get to boot up and show menu on dual boot with Vista initially,However when I delete the grubenv file the system boots ok and works fine.But does not show the grub menu to choose boot up choices.Got the information to delete the file on some posts elsewhere about booting problem, and tried a longshot and got into Ubuntu for the first time from trying to install now for 3 months!The problem is the file grubenv is created each time so on subsequent boot ups the sytem fails to boot again.The Grub version is 1.97 beta 4, most up to date for Karmic I think, I have seen a version 1.98 but dont think its for Karmic?
Is there a way to modify the grub.cfg file to stop this problem ( all posts say dont touch this file??Or install a script to delete the grubenv file on shutdown as a workaround for me, (I have no idea how to do this whatsoever, I'm not familiar with linux at all)I did read that this problem was fixed/patched in Grub version 2, but dosn't seem.so on my system afetr I updated it when I got into Ubuntu.I couldnt find the patch or fix, I got the information I am on about from this post:URL...It seems to say it was fixed or patched by Colin Watson reading through, but I don't really understand whats being said or how to get the patch on my system if indeed there is one?Sorry for being a bit thick about all this, its a bit beyond my brain now, hope somebody can help out as I have enjoyed my brief bit of fun in Ubuntu.

I have noticed in the recent updates there is a Kernel update 2.6.32-22 but there is no restricted modules included. On my Desktop I have a Nvidia card which I installed the driver using the Hardware Drivers Application. As far as I know these Drivers are ether reinstalled or updated whenever there is a kernel update.
I also have a Laptop with a ATI Radeon card which I did run the updates and ended up (after the reboot) in low graphics mode, after a bit of work I was able to reinstall the drivers and get my desktop back so that's ok now.
I had this problem a few years ago with an old version of Ubuntu, kernel updates but no restricted drivers. The drivers turned up the next day and all was fine. I was just wandering if this is a known issue with Lucid or if anyone else has had this problem, It's been a couple of days since I noticed the Kernel update but still Restricted Modules. Oh I'm using Ubuntu Lucid 10.04
