Ubuntu Installation :: Cannot Boot After Accidently Removing Kernel Image
Apr 19, 2011
I have Ubuntu 10.10 installed on my laptop.Its a dual boot with XP, have been using ubuntu/xp for a while now..Till now i always used to remove older kernel images after ubuntu update, then update grub and do "sudo apt-get autoclean" never had any problem at all.i skipped the second step, i removed the old kernel image and did "Autoclean" on apt-get but forgot to update grub.
Now after i have reboot, when grub loads i can see only 2 "Memtest" lines in grub list and 1 "windows xp" line.the "Linux kernel generic" line is missing. I can boot in xp (have done just that to post this) but since there is no line in grub list to boot into Ubuntu, cant boot in Ubuntu.Is there any option, something i can do at "Grub" to boot into Ubuntu?

Other than the linux kernel image I am using is it ok to remove the others I have and thus gain more disk space ? I only have a small asus 900 netbook.

I have winxp and ubuntu 10.04 dualboot. They were working ok. Today I removed old *21 kernel image and headers so grub updated the confs. That's all I did that could cause the win no longer boot. It starts booting, the screen goes black and the PC reboots. I tried safe mode, it started to load some dlls as it usually shows in safe mode but then still reboot.
Code:
$ sudo fdisk -l
Disk /dev/sda: 160.0 GB, 160041885696 bytes
255 heads, 63 sectors/track, 19457 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes

I am new and recently almost one month back installed debian linux stable 8.2 came from windows. Today I upgrade my debian stable 8.2 to testing and everything works fine. Just one thing is that I checked kernel and find :
uname -r
4.2.0-1-amd64
dpkg --list | grep linux-image
ii linux-image-3.16.0-4-amd64 3.16.7-ckt11-1+deb8u5 amd64 Linux 3.16 for 64-bit PCs
ii linux-image-4.2.0-1-amd64 4.2.3-2 amd64 Linux 4.2 for 64-bit PCs
ii linux-image-amd64 4.2+68 amd64 Linux for 64-bit PCs (meta-package)
I am first time removing old kernel so cant take risk from searching the solution from google so come here, what and how to remove that includes everything like kernel image and other old kernel files not needed.
One more thing I just realised and saw on details in settings gnome that
Base : Debian GNU/Linux stretch/sid 64-bit
Is this right as it says sid in the line but i just changed my sources.list to testing only and then aptitude upgrade and full-upgrade then just.

The uderscore is flashing and i can type stuff in but have no idea what to type in to find the kernel image, or why it cant find the kernel image.

I have downloaded the i386-DVD.iso image and have burned it on a DVD using Nero Express 6, when it boots from the DVD, it give me an error message "Could not find kernel image: Linux" and the boot: prompt after that. I have burned another DVD using Infra Recorder with minimum write speed but with the same problem. I have Ubuntu already installed on the computer.

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?

Here's how to always have only the latest kernel version in your grub:
Code:
sudo gedit /etc/grub.d/10_linux
Find these lines:
Code:
list=`for i in /boot/vmlinu[xz]-* /vmlinu[xz]-* ; do
if grub_file_is_not_garbage "$i" ; then echo -n "$i " ; fi
done`
And change it with this:
Code:
for ver in /boot/vmlinu[xz]-* ; do
list="$ver"
done
Notice two differences.
1. There's no ` before "for" and after "done" keywords.
2. There's no list= before "for"
If you want to change the name of entry, scroll down to the end of the file and find last two occurrences of:
Code:
linux_entry
${OS} stands for Ubuntu and ${version} stands for your kernel version. I changed this into:
Code:
linux_entry "${OS} 9.10 Karmic Koala"
You can use your own imagination. If you want to have specific name for your Windows entry, in /boot/grub/grub.cfg copy everything between:
Code:
### BEGIN /etc/grub.d/30_os-prober ###
and
Code:
### END /etc/grub.d/30_os-prober ###
paste it in
/etc/grub.d/40_custom
Change the text between double quotes right after menu entry. (For example, my 40_custom looks like this now:
Code:
#!/bin/sh
exec tail -n +3 $0
# This file provides an easy way to add custom menu entries. Simply type the menu entries you want to add after this comment. Be careful not to change the 'exec tail' line above.
menuentry "Windows 7" {
insmod ntfs
set root=(hd0,1)
search --no-floppy --fs-uuid --set bcdc24dddc249424
chainloader +1
}
)
and make 30_os-prober not executable:
Code:
sudo chmod -x 30_os-prober
If you want to remove recovery mode entry, just uncomment this line in /etc/default/grub:
Code:
#GRUB_DISABLE_LINUX_RECOVERY="true"
PS Don't forget to run
Code:
sudo update-grub
After you finish editing everything! And check in /boot/grub/grub.cfg if everything is ok!

I have looked for existing threads on this issue, but found no matches, so I am starting a new one.I first installed Ubuntu 9.04 on my laptop from a bought CD last year. When I later installed the kernel updtates with the Update Manager, I noticed the the list of versions growing when I booted up. Then something horrible happened. After installing maybe the third or fourth kernel update, I couldn't boot into Ubuntu, it failed every time. After that I left Ubuntu broken on my laptop for a while.I have now reinstalled from the CD again However, I am now very wary when it comes to installing even the important security updates, never mind the recommended ones! I prefer to keep it simple, because I don't want to do any more reinstalls for a while. So far I have just one kernel headers update on the boot list, and I am trying to figure out how to remove the previous one. I do not see the point in having a growing list of them again.

Ive been trying to PXE boot a XEN kernel image in gzip format, and I was getting Invalid or corrupt kernel format error. Ive seen that other kernel images having a file type of Linux kernel x86 boot executable RO-rootFS are bootable. (both are bootable using grub anyhow).
Is there any way to convert the b/n the formats, or any other solution?
I was booting a Virtualbox instance, again I guess that shouldn't matter because pxelinux loads from tftp properly, but it doesn't even proceed to load the kernel. I think the issue here is with the image format itself rather than what it contains, or where it runs.

I had the 180.xxx nvidia drivers on my FC10 setup.I installed the 185.xxx and am running into issues. It gives me the fatal server error: no screens found message. Before that it says that the nvidia kernel module is 180.xxx and the driver component has 185.xxx. I can't seem to figure out how to uninstall the previous module to make this work. I removed the yum kmod nvidia. I'm running this using sh nvidia.185xxx.xxxx.run . The weird thing is that it sometimes would work but then I would restart and it would break again.
Thanks in advance,

I just did an upgrade and it included the kernel. As time goes by, I will be stuck with a lot of kernels to choose from, and lower disk space. How do I remove an older kernel and everything it's related to it without breaking stuff?

I am ready to reclaim the disk space that is currently being used by XP in my dualboot scenario. Per the Gparted scan below, my hard drive is currently being sequenced as sda1 (NTFS data only, which I mounted in Ubuntu and write my working documents to), sda2 (XP operating system/boot drive). Ubuntu is on sda3, with home on sda4. I'm currently running 9.10.
I would like to eliminate the contents of sda2, and migrate sda1 contents to ext4. Question is, what are the best steps. I have good backups of everything, and sync my NTFS data to a NAS.
My grub.cfg looks as follows (am running 1.97)

Can i even format without removing windows in the progress? If not, what would be the best way to just remove everything i have on the computer to get it as close as possible to a new computer? I don't have windows install CD because the laptop had Vista pre-installed. So i must be careful what i remove or my brother won't buy the laptop I'm mostly concerned about killing the GRUB and making me unable to start the computer.

I am currently running Fedora 10 XFCE on an Acer Aspire 1 (1.6ghz atom, 1.5gb ram, 8gb ssd). I am trying to install Fedora-11-i686-Live-XFCE via USB stick (Kingston 4gb) and am having no luck. I downloaded the .iso via bittorrent. If I use liveusb-creator: .iso passes checksum, installs boot image, installs syslinux, claims it's complete. When I try to boot, or simulate booting with qemu, I get the message "Could not find kernel image: linux" If I use
Code:
# livecd-iso-to-disk /home/jorge/downloads/Fedora-11-i686-Live-XFCE/Fedora-11-i686-Live-XFCE.iso /dev/sdb1
it says that the .iso passes checksum, installs live image, updates boot config file, and setup USB stick as a live image. Once again though, when I try to boot, or simulate booting with qemu, I get the same message "Could not find kernel image: linux"

what i did was, remove evolution mail from synaptic, what i wanted to do was just remove the indicator applet from the task bar. i read a bunch of bad stuff about removing evolution from synaptic vs just removing the applet.
im worried. did i break anything or put my security at risk. after, i used a command (older) (sudo apt-get install ubuntu-desktop)to install ubuntu desktop. because i thought that it would fix evolution. then i went to synaptic and installed a package called evolution. i rechecked evolution in applications menu. however, i notice that i have both a checkable evolution and two evolution icons. nothing 'seems' broken. im not sure if it ever was. and evolution calender pops up as normal, as does the the installed plain evolution. they both seems to be an exact copy of the other.
all i really wanted to do was remove the indicator applet. did i make a serious mistake. since ive had ubuntu, ive reformatted a lot because i was worried i made a mistake of some kind. however now im into the more "make a mistake and fix it stage' as im pretty happy with my current desktop and have worked hard to customize it. the command, sudo apt-get remove indicator-messages removed the mail icon. i still am worried that i broke something, or put my security at risk. also, now i have two mail icons. evolution mail and calendar, and another just called evolution.

I just built this computer with a bunch of old parts, and i put in a blank hard drive. There is no operating system on this computer yet. I put the Ubuntu Usb into the computer and made it boot from the Usb. Everything looked fine and good, until it said "boot:". It wanted me to type something in. So i clicked enter and it said "could not find kernel image: linux".

I use a pretty fresh installed RHEL 5.4, which should be very similar to Fedora. After the basic installation I installed xen and xen-kernel via yum with no errors. I can select the xen-kernel at boot time. But after booting the normal kernel shows up.
[root@noname boot]# uname -r
2.6.18-164.11.1.el5
My /boot/grub/menu.lst looks like:
default=1
timeout=5
splashimage=(hd0,0)/grub/splash.xpm.gz

I can't see anything wrong and I did not change/try anything.

I'm trying to run extract-ikconfig because I've mistakenly deleted an old kernel config that I'd like to recover. However, when running the script from the latest (2.6.32.5) tree I run into this error:
Quote:
ERROR: Unable to extract kernel configuration information.
This kernel image may not have the config info.
Coincidentally, this happens with all of my kernel images. Is it a fixable problem? I should really set CONFIG_IKCONFIG_PROC next time..

My HDD crashed (it wasn't completely disastrous, though). I was able to get my Ubuntu 10.10 partition of the disk with dd_rescue. I can see all of the data in the partition and everything. dd_rescue reported that there were no errors.Now, I have a fresh HDD, and I copied the image that I created with Gparted, and turned the boot flag on. I turn my system on, and all I get is a flashing cursor in the corner of the screen.I get the feeling that this would be easy for a seasoned user, but I'm not sure where to go. I originally got some information about cloning partitions here: [URL] But, it doesn't tell you how to reload the image after you make it.
