General :: GRUB Command To Change Kernel?
Feb 19, 2011
I just got a laptop (DELL PP06S) from a friend set up on kubuntu. He told me to download and run the updates packages if I had time. So so did I and now the computer stops on an error at boot and I can't log in at all to type any command. The error message coming up is:
ata1.00: exeption Emask 0x0 SAct 0x0 action 0x6
ata1.00: BMDMA stat 0x24
ata1.00: failed command: WRITE DMA
[code]....
And it seems to try that action over and over but I never get to log in and type any command. I got told to check the drive cables connections, which I did but it made no difference. I also got told that I could try to start with an older kernel, I tried all the different kernels available in the GNU GRUB but no success. The different options availables are:
Ubuntu, with Linux 2.6.32-26-generic
Ubuntu, with Linux 2.6.32-26-generic (recovery mode)
Ubuntu, with Linux 2.6.32-25-generic
[code]....
From my understanding these are the new and older kernels, is that right? I had to do the updates in 3 times so I guess the kernel from before then isn't in the list anymore. Every one of them shows the same error message and no way to get a console. So I can't type any command. Though, I found out that I can type commands in the GRUB, is there any way to change the kernel from the GRUB? If so what would be the commands?

I have Lucid on my laptop. Unfortunately, with the various 2.6.32 kernels neither hibernate nor suspend work, so I've installed and use the last 2.6.31 kernel that came with Karmic.Now, I'd like to set it as default, so that I don't need to actively choose it when I boot. The problem is that I can't find a way to set Grub (version 2.0, or 1.96rc, can't remember) to pick the 2.6.31 kernel and if I try to uninstall the 2.6.32-23 kernel synaptic says that linux-generic and linux-headers will also be uninstalled (not just the parts specific to 2.6.32-23).

my Setup is Fedora 14 x64 + radeon hd 4830 i've downloaded .run package from ati site with latest driver for x64 systems. installed it, but didn't edited grub.conf becouse i didn't understood anything there (probably didn't spent enough time to get things understand) Now i've lost possibility to enter my Fedora system. during boot it lost it's modern blue boot screen (with filling drop), it was replaced by standard old boot screen with triple-color stripe. after this boot screen monitor start blinking going on and off. and on last step i'm getting "Fedora 14 boot bla bla bla something" on screen. nothing works except Ctrl+Alt+Delete. system reboots showing successful daemons shutting sequence. How can i edit grub menu from initial grub screen is it possible to it's own 'e' option or 'c' from grub command line?

I have problem with my Ubuntu,Whenever I ran "sudo update-grub" command it did not detect my Ubuntu kernel nor Windows XP installation on another drive (I installed Ubuntu and Windows in different drive).It just display "Generating grub.cfg" and then "done". No "Found kernel..." message.

I'm using 2 cloned disks with CentOs5.3 and I need to be able to control which one is booted. I can specify which disk in the BIOS but after stage 2 it is always running from disk 2. When I have puppy linux on one disk and CentOs on the other I can boot off of either as selected by the system BIOS so the BIOS is not the issue. I think it is how the root option is passed in the kernel command in the grub.conf.
kernel /vmlinuz-2.6.18-128.el5 ro root=/dev/VolGroup00/LogVol00
I think when the OS searches for the /dev/VolGroup00/LogVol00 share is locates 2 since the disks are clones and uses the last one found. On information I have found for the kernel command and the root option it appears CentOs uses it differently. CentOs uses a volume name as specified /dev/VolGroup00/LogVol00 instead of a partition designator /dev/hda2. Is there a different way to specify /dev/VolGroup00/LogVol00 in CentOS for the root option for the kernel command of grub.conf?

I found a way to change the kernel time zone with the following command
$ ln -sf /usr/share/zoneinfo/* /etc/localtime
After I tried it and checked the kernel time zone, but it didn't changed.
It seemed to be applied after rebooting.
Is there any way to change the kernel time zone "dynamically" with the
console command, not with the GUI environment?

change the boot menu - GRUB
I regularly update my ubuntu (10.04), and new minor versions keep accumulating on the GRUB screen. Right now I have 5 different versions listed on the GRUB, even though I always select the latest version to work with.
Am I supposed to do anything to get rid of the old version references? Do these old versions affect disk space/performance?

I have looked at the GNU GRUB Manual 1.99 at [URL] but I cannot find an explanation of what the kernel entry / command in the grub.conf file means. I get what's the meaning of that entry but where is described what it actually is and what are proper.
I suppose this entry / command was actual in GRUB Legacy, but I cannot find where it is described...

I am trying to do a fsck on my ext3 partition, but so far failed to let the system come up in single user mode and having the partition mounted read only. It says in the kernel parameter that it is read only (RO) but still mounts it RW. A remount with mount -o remount,ro does not work, since / is always busy. what to do to get a fsck done? I don't want to boot into a rescue system, this should be possible on a running system (like Windows does it, when rebooting)

I unfortunately remove "some" softwares on my OpenSuse10 (preinstalled on my laptop, without cd driver) cause I was running out of space on hd. Icons starts to dissappear ...
Then I have only the Grub 0.97 shell that appears and to use to solve the problem... tried to boot kernel, but said that it "must be loaded before boot".
In the Grub 0.97 black window I have two lines :
I press "b", to boot with the First line : kernel (hd0,2)/boot/vmlinuz ... but the window turns blue and said "all data would be lost", so it shut down the system automatically to avoid this.
I press "e" to edit the command in the boot sequence for the same line, but don't really know what to tell Grub to do.
I must get my important datas back on my hd before "Restore to factory settings" (the last option). Any solution ?
Maybe it is a step on a solution ?
From [url] I downloaded linux kernel 2.6.27.27 on a usb memory stick. Could it be useful ? how to ?

I am a linux noob and that is the reason I want to boot my windows xp by default. Now kubuntu boots first. I've googled how to do this but the topics of other people with the same 'problem' were old or maybe incorrect. Because the official GRUB Ubuntu wiki says you should not change the /boot/grub/grub.cfg file manually. The first line on the .cfg file is also a warning: Do not edit this file. So it continued looking for a proper way to change the boot order. Then I found something about etc/grub.d and also etc/default/grub. The problem is I don't understand how to change the boot order using this.

I've seen many, many different solutions for how to change the GRUB boot order. Search no more. This is by far the easiest, safest way to do that.
Open your terminal and type in the following:
sudo apt-get install startupmanager
When that is done go to your control panel and you'll have a new icon that says Startup Manager. Every thing you'll need work with your GRUB menu.

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."
