Ubuntu :: Kernel 17 Update - Grub2 Broken Again
Jan 7, 2010
So I know I should have known better then to turn my updates back on after the 15 and 16 kernel updates crashed ubuntu and grub but I did anyway and once again after a new kernel gets installed I'm stuck at the grub sh prompt.
Been down the road before... tried using
linux /boot/vml....... root=/dev/sda1 loop=/ubuntu/disks/root.disk ro
When I use the 16 or 17 kernel I get an error stating "invalid imaginary number"...
So I use the 14 kernal and enter
initrd /boot/initrd.....
boot
And it boots like it did the last time this crashed. I went to the terminal and entered
sudo apt-get install grub 2
sudo update-grub2
And then rebooted like I did last time expecting the problem to be fixed and at least be able to boot up the 14-generic. It didn't fixed this time. So now what do I do to fix grub and what do I do about having 2 unbootable kernals??

After updating to version 2.6.31-20-generic, my desktop computer with an ATi HD4850 graphics card, using the fglrx driver, now won't boot to X. It goes through the boot process and displays the splash screen, but after that there is nothing on the screen. Choosing an older kernel version from GRUB doesn't make a difference. I don't even know how to diagnose the problem properly. I can boot into recovery mode and get to the command line, however, starting x from there only leaves me with a blank screen.
so the source of the problem is that I had installed the catalyst driver from amd.com, which needs to be reinstalled with every kernel update. I didn't know this in advance, so now I'd like a way to revert back to fglrx from the repos. Sadly, the community docs only seem to cover the graphical way of doing this, which is kind of useless to me at the moment.The ATi driver docs gave me a way to uninstall the catalyst driver using only the command line. So now I've booted back into Ubuntu and selected to install the fglrx driver from System → Hardware Drivers. However, now when I boot up, I get the message: "(EE) Unable to initialize PCS database

I just upgraded the kernel on my Ubuntu laptop from 2.6.32-24-generic to 2.6.32-25-generic (using the update manager under gnome). After the update, the wireless network controller shows up as UNCLAIMED when I do lshw -C network.When I try to install the driver with the commands sudo modprobe lib80211 sudo insmod wl.ko
i get this error message: insmod: error inserting 'wl.ko': -1 Invalid module format
I have compiled the driver using the 2.6.32-24 kernel. Do I have to re-compile with the new kernel?I'm a unix user, but not a kernel hacker, so I'm wondering if I will run into problems every time I get a kernel update? Or is this problem an exception?

After i updated to the kernel version 2.6.34.7-61.fc13.x86_64 my wireless stopped working!
My network card is a Broadcom Corporation BCM4311 802.11b/g WLAN (rev 02)
The interface is not listet anymore under ifconfig, under the network icon i see only wired networks.
If i boot using the old kernel (2.6.34.7-56.fc13.x86_64) everything is fine.
when i run lshw -C network i can see that the driver is not loaded correctly
Code:
*-network UNCLAIMED

I use Arch Linux and the kernel got upgraded, and it broke VirtualBox. It says to run "/etc/init.d/vboxdrv setup", but such a file does not exist. The Arch Wiki says "/etc/rc.d/rc.vboxdrv setup", but that doesn't exist either. What should I do?
And is it possible to write a script that runs on startup that automatically fixes VirtualBox whenever the kernel is upgraded?

I am currently working to get to a stable dual boot Win7/CentOS 5.5 configuration on a Dell Latitude E6510 with the Intel 82577LM chipset. I haven't gotten the Centrino N WiFI chipset working yet, but the Eth0 device was working just fine.However, yesterday I did a system update. I did not pay close attention, but I believe the update did mention networking, because I thought it might help me get my wireless going. Now, Eth0 fails with the message, "Determining IP information for eth0... failed; no link present. Check cable?" It does this at boot up and if we try reactivating it once the system is up. We have tried unstalling and re-installing the driver.The Window 7 boot sees the adapter and runs just fine. I was at a different site location yesterday when everything was working, but my co-workers and I can't help but think it might be related to the update yesterday, since everything worked prior to the update and Windoze 7 works fine with the adapter.
I have not been able to mount my NTFS harddrive on the CentOS side, despite installing fuse, and I don't have wireless, which makes it difficult to get access to new drivers. I also have a FAT32 partition that would be great to share between the boots for passing info, but I haven't found a way to mount a FAT32 partition in CentOS.

The kernel-PAE-2.6.30.5-43 upgrade will not boot on my Dell 1545 notebook. The initialization stops and the systems freezes right at the point that the login prompt should appear. I do not have invidia drivers. I have Intel video drivers. Also there is a loud 'pop' in the sound system early in the initialization sequence. For the time being, I have removed the 2.6.30.5-43 upgrade via yum.

I was doing a kernel update and can no longer boot into 11.3. I am dual booting with XP. I get Grub screen but no longer see Suse as a boot option, only Windows. I have tried to reinstall, but for some reason I can't get it to boot with DVD. So, is there a way that I can repair my computer without doing a reinstall?

I had a working ubuntu 10.10 system two days ago with kernel 2.6.35-24. I have a gtx 460 card so I have the driver from Jockey/Additional Drivers installed.
Two days ago update manager prompted me to install 2.6.35-25. I've never had problems updating kernels so I did. I Rebooted my machine and gdm/gnome no longer starts. I always get stuck on the tty1 screen. I did some troubleshooting and figured out that my current NVidia drivers seems to be messing it up. So I booted into my older kernel (2.6.35-24) and removed my NVidia driver.
I used these steps to switch from nvidia to nouveau:
NvidiaDriverSwitching
I can now boot into my latest kernel (2.6.35-25) but now I'm having problems trying to reinstall the nvidia drivers.
jockey sometimes doesn't list any available drivers. and when it does, it gives me an "System InstallArchive() error" when trying to install.
I tried installing nvidia-current via apt-get and I get these errors:
Code:
Setting up nvidia-current (260.19.06-0ubuntu1) ...
Removing old nvidia-current-260.19.06 DKMS files...
dkms.conf: Error! No 'DEST_MODULE_LOCATION' directive specified.
dkms.conf: Error! No 'PACKAGE_NAME' directive specified.

I am currently in a country where the internet speed is roughly 15KB at best, if at all. So I cant download the 9.10 live CD. My grub2 broke when I reinstalled windows (because its so virus prone). This guide: [URL]. Says how to repair grub2 using grub2 live CD. Currently I have access to a 6.10 Ubuntu CD but when I try to mount the boot partition I get an error saying that the filesystem has unknown options. I think that the latest filesystem didn't exist back then and even if that would work. Can I reinstall grub2 using grub? Or is there any possibility to download an ultra small linux live system image with grub2? it seems all ubuntu variations come in 500MB+ packs.

I took the distribution upgrade from the update manager and can't boot now. Boot into a Live CD (ver. 9.10 - does that matter?), and go through the following steps.
ubuntu@ubuntu:~$ sudo fdisk -l
Warning: invalid flag 0x0000 of partition table 5 will be corrected by w(rite)
Disk /dev/sda: 750.2 GB, 750156374016 bytes

Units = cylinders of 16065 * 512 = 8225280 bytes
Disk identifier: 0x000ad56f
[Code]...
Anyone have an idea here? I have searched a lot and have only found a few references to this issue. Does the invalid flag message relate here? The partition is flagged as 'boot'.

i havent really had a chance to ask this for a while, but im in a bit of a bind. im trying to do a release upgrade of 9.04 through to 10.10. I'm stuck at getting karmic to reboot because of a grub problem. I keep getting "error 15" file not found. Not one single forum post has helped for some reason which is strange. Release upgrades have always worked even though not recommended, but this one of all has been the worst of the lot and totally insane.
Im testing in a vmware before i do this for real on the production server, I am using a raid1 setup and boot partitions set to md0.
my fstab after the upgrade before i reboot looked like this
# / was on /dev/md1 during installation
UUID=######################## / reiserfs relatime 0 1
# /boot was on /dev/md0 during installation
[Code]....
I tried to first install grub2, i confirmed it installed and worked perfect, and therefore removed grub legacy.
Ran do-release-upgrade , it completely uninstalled grub2, and it also fails at building /initrd.img-2.6.31-22-server and adding into the grub menu therefore the upgrade fails with this error. I reinstalled grub2, the menu came up fine but trying to load a kernel gave me something like
alert ! /dev/disk/by-uid/############## does not exist.
What is the go with this ? Ive been trying to make this work off and on for 6 months

I started the upgrade to 10.4 from 9.10 through the update manager. It started the update to 10.4. After downloading almost 95% of the update, it gave an error message of "could not download certain components. downloaded files will not be erased" and stopped the update. I restarted the PC, and started the update manager again. But now it does not show any option of update to 10.4. how do I continue or resume the update process? I just started using ubuntu about 15 days back. So, I am relatively new to this.

I have been reading for hours and just do not get how to do this simple task. I need to add a couple of kernel options to the 3rd menu item that shows in my grub.cfg list. I understand which files to edit (not grub.cfg) and run the updater.
If I look in /etc/default/grub I cannot figure out how to add a kernal parameter unless it is the default.
So basically I want to change the equivilent of this line below:
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"
But for a kernel menu item that is not the default.

I've had a fairly trouble free dual boot system for about 7 months now, windows vista / ubuntu 10.04 on separate drives. Got a little lazy and had quite a backlog of updates to do in ubuntu so I started up the update manager and let it do it's thing overnight. When I checked in it was waiting for a reboot to finish installing, which I did. When grub came up every selection returned the same error: file not found and must load kernel first, press any key to continue which leads back to the selection menu. Windows still works fine, and with a live cd I can see the the normal file system stuff is still there: filesystem, intrid.img , intridimg.old , vmlinuz , vmlinuz.old... etc.
Tried the live cd terminal to install grub.. grub-setup, grub-install, grub-probe all return the "/usr/sbin/grub-probe: error: cannot find a device for /boot/grub (is /dev mounted?)." line.
Anyway here is the boot info script results.

I have not dug into Ubuntu for almost a year now (Since Jaunty, really). I am trying to come to grips with Grub2, but have just now encountered it in Lucid. I am having a terrible time with the graphics chipset, and it may well be that Ubuntu cannot be used on this computer (an older laptop with the dreaded Intel 82845G graphics chip). There are a number of older bug reports that it is unsupported, but some success in more recent versions.
Anyway, one suggestion has been to add i915.nomodset=1 to the kernel boot line. Now, this was a cinch in Legacy Grub, but I have been reading Grub2 wikis and tutorials for two days now, and I know about the config files, but I cannot find anything which tells me specifically how to add a parameter to the kernel boot line.

I have been running Ubuntu 10.04 for a while now without any issues. I have also been dual booting with grub2 for a while now, only issues being crappy customization. But anyways I had my grub2 splash all set up the way i liked, with a nice background and everything. I run every update Ubuntu wants and have never had an issue until recently.
On June 3rd I ran an update that Ubuntu requested, it installed a new kernel (-2.6.32-22) and requested a restart, as usual. after restarting, my grub splash is gone. I thought no biggie ill just run `update-grub` as i have before and it will fix everything...nope
I get the error message `head: cannot open `/boot/grub/video.lst' for reading: No such file or directory` right where the "image found" message is supposed to be.

I have a problem with my touchpad, sometime it doesn't work at start-up and this happens randomly.
I have looked around and maybe I could solve this with the procedure described in [url]
I'd like to add the equivalent of to kopt in the old grub.
I looked into the grub2 documentation, [url]
I am not even sure if I have to modify /etc/grub.d/40_custom or 10_linux.

How do you go about removing old kernel from other distros from the grub menu. For example I have lucid and ubuntu studio installed. Lucid controls the grub2. So how would I remove the old kernel out of the ubuntu studio?

I've been using Ubuntu since 7.10 Gutsy Gibbon. I only recently fully switched to Linux OS's, and Ubuntu is now my primary. I currently have 9.10 installed. CURRENTLY I also have Backtrack 4, and Fedora 12 (Ugh!).Previously, I thought something was wrong with my my filesystem in Ubuntu 9.10, and after an upgrade of the linux kernel, I started to get Error: You need to load the Kernel First. That's where my problems started. I had upgraded to 9.10 from 9.04 and I still had Grub Legacy, so I went through hoops to try and get it to work, but eventually everything just kind of broke, and I completely wiped off my partitions on it and started fresh installs of all 3.
And now that the new linux kernel is released, 2.6.31-20 generic (I think... That's what the highest number on a file I can find in /boot is)I went through a few more hoops and ladders and tried to get it to work, but to no avail. I've looked the internet for a solution to this and tried just about everything but there is no unified answer, and I've seen on Launchpad there are alot of bugs that are classified as 'Fixed', but the problem still remains.I took out the 'quiet splash' part in the GRUB2 line for the newest kernel and it didn't do anything. It only changed it to "Error: Couldn't find file".This is the top two kernels (Main and Recovery for the new, and Main and Recovery for the previous working one)

So I currently have an Ubuntu/Mandriva/PCLinuxOS multiboot setup on my system. After I installed the latter two I setup Ubuntu's grub2 to be my default boot manager. After running my Code: sudo update-grub command it successfully found and added entries for Mandriva and PCLinuxOS, however upon trying to boot into either of these distros (selecting them from the menu) I get some terminal output that ultimately ends in kernel panic.
