i have just finish compiling a new kernel from source and would like to know how to load it in to grub2 i know grub the older version was easy to setup with the new kernels but i am not really in to grub2 to know how to load a new kernel to it.

I want to load grub2 from grub4dos.I want to load directly the grub2 core. I know how to load first 512 bytes from some patition by chainloader and load grub2, but what I need is to load directly grub2 core without passing by bootstriping code (first 512 bytes).So, my first boot manager is grub4dos, then I can load grub2 and later I load Ubuntu. But I think I have to edit --set-root
What I dont know is how.
In hdd 0,7 (sda8) I have Ubuntu 10.10 and /boot/grub/core.img is in sda8 (hd0.7)
I tried this way:
Code:
title grub2
find --set-root /boot/grub/core.img
kernel /boot/grub/core.img
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)

i initilally installed ubuntu 9.10 then installed windows 7 ,then i recovered grub2 using livecd as told in the post [URL] i did "sudo update-grub" and got windows 7 menu entry but when i select that entry windows 7 does not load but the grub2 is reloaded again.
i cant boot to windows 7.
Windows 7 have 100 mb partition "System Reserved" the grub2 points to that partition but still windows 7 not loaded.

I am trying to figure out how to load the generic kernel in Grub2.
I have run the /usr/hare/mkinitrd/mkinitrd_command_generator.sh and ran the output:
Code:
Why this will not load.
So I recently tried to install Ubuntu Lucid in the following configuration code...
The installation procedure went fine, and it said it had successfully installed GRUB2. But then, when I tried to boot up the fresh system, GRUB2 didn't even load!!
It's not giving me any GRUB errors, or giving me a 'grub recovery>' prompt, so I suspect that it really isn't even booting into GRUB.
I tried booting into the LiveCD, and installing grub to BOTH /dev/sda and /dev/sdb, but it still does not work, and I am at a loss.
Has anybody else had this problem?
I have old laptop without CD (already it's dead), FDD was not from the beginning. This laptop have USB but can't load from USB. I install grub2 but it's work not correct.

I am a long time ubuntu user (4.10) and have had a fair bit of experience installing ubuntu and the many mishaps along the way.
So after having no internet for a year I decide to try the new 10.04 flavour by ordering the cd from the site.
Installation went well, no hiccups. But when I restarted the comp it went straight to Xp, so I thought I'll just use the SGD to boot the partion anyway and fix this small problem later.
After SGD confused sda with sdb, I figured out that GRUB2 is now the standard boot loader.
So thats where I am lost, I have searched the forums quickly (25 pages or so..) and realise that I am not going to fix this easily or by trial and error.

I have a number of legacy pcs upon which I would like to install Lubuntu. None have CDROM drives, but they do have floppy drives. None can natively boot from USB devices. My goal is to boot into Grub2 from a floppy with USB support, but I'm having trouble making the floppy. I've seen recommended a few times a command string something like
Code:
grub-mkrescue --overlay=/boot/grub --image-type=floppy GRUB2.img
dd if=GRUB2.img of=/dev/fd0
But when I go to do this, grub-mkrescue has no --overlay nor --image-type option. My man grub-mkrescue page only lists --modules and --output as options. I have managed to make a floppy using the commands
Code:
grub-mkrescue --output=FILE
dd if=FILE of=/dev/fd0
This disk does boot into Grub2. The problem with this is that I need to add other files to the disk to have USB functionality in Grub2, but this process writes to the floppy in iso9660 format, which mounts as read-only. I have tried to go this route using the mount -o remount option to try to make the fs rewritable, but I also haven't been successful with that (and I think my limited knowledge is restricting me here).
Maybe I can add the correct files to the file output by grub-mkrescue --output before I write it to the floppy, but I also don't know how to do that.
Basically, I'm a little burned out and looking for some direction. Am I going about this wrong? When I try and follow other people's guides, they seem to have options available to them that I don't have. I'm doing all this from my Lubuntu 10.04 live CD, but have found similar things on my regular Ubuntu 10.04 install as well.
I' ve tried to do a iso multiboot 1gb pen stick with grub2 bootloader. I 've already readed all is it possible finding on the WWW but there are some problems i don't understand how to solve.
This is my sitution:
-koala 32bit installed on my pc with grub2 bootloader
-1gb pendrive parted as follow:
In the first fat16 partition there is installed grub2. On the second ext2 one there are iso files.
This is what i've do to install grub2 on my pen:
So i've created /boot/grub/grub.cfg file with the follow lines:
When i reboot by the pen stick, grub load up to it says me:
It seems not reding /boot/grub/grub.cfg
So I have an MBR that is Grub legacy,(from HardyHeron) and I cannot edit/upgrade this MBR. (I won't get into the reasons, other than I will mention SafeBoot).
I have a new encrypted LucidLynx Linux installation on partition 4 and an unencrypted /boot partition on partition #3.
When I boot up, I get the "Error 15" Grub error, which is expected as Grub legacy is looking for /boot/grub/stage2 or something like that and /boot/grub/stage2 does not exist in my GRUB2 installation in /boot/grub.
I thought if I could make a link from the GRUB2 binary of interest to /boot/grub/stage2, then maybe the GRUB legacy would be tricked into loading the GRUB2 binary.
what is the binary of interest in the GRUB2 installation that is the main binary?
Very strange Grub2 issue on my Dell Mini 10.
Had Crunchbang Statler on it, and after an update, it would hang at grub, before the grub prompt. ("loading Grub, Welcome to Grub" then blinking cursor, but no prompt or ability to get into rescue)
So I booted into a liveCD, chrooted in, and reinstalled Grub2, purging everything. No dice. Same problem.
So I figured the device maps weren't right, so I pulled off any important files via the live stick, and reinstalled #!. Same problem.
Did a bit of googling, and it seemed like it was most probably not a true Grub2 error, but a bios problem, so I reinstalled XP, flashed to a new bios (A11).
Then reinstalled, this time with Zenwalk (figured it might be a debian thing). Same thing. (note I replaced lilo with Grub2 for puroposes of testing)
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'm attempting to triple boot Windows 7, Mac OS X, and Ubuntu 11.04 on non-Mac hardware. Chameleon is my primary bootloader, which is supposed to chainboot into grub2, but all I get when I choose the Linux boot option is a black screen with blinking cursor. If I try to boot Ubuntu while holding shift, I get the word GRUB, followed by a space and a blinking cursor. grub2 is installed to the Ubuntu partition, and attempts to reinstall it there or to the MBR from a LiveCD result in errors. The MBR and GPT partition tables are synchronized. How do I go about making Ubuntu bootable, without breaking my other two operating systems (or at least leaving them recoverable)?
I built a new desktop computer.The goal was to triple boot the system with Windows 7, Mac OS X Snow Leopard, and Ubuntu 11.04. This endeavor has been significantly more complicated than I originally expected, but with the of a forum-goer at InsanelyMac.com, I've managed to get pretty far with a complex installation process. I've attempted to get Ubuntu running using two methods, neither of them achieving what I'm hoping. Both methods follow.
In the first method, I install Mac OS X using a specially designed install CD that boots into the Snow Leopard installation DVD. The disk is partitioned to have a FAT partition, followed by a Mac OS X journaled partition, ending in a second FAT partition. Mac OS is then installed to the second partition. The Windows boot CD is then used to format the first FAT partition as NTFS, which Windows 7 is then installed to.
As I'm sure you know, this installs Windows Boot Manager. Then I boot into OS X using the boot CD mentioned earlier, and install Chameleon, a bootloader specifically designed for Hackintosh systems, and (supposedly) capable of booting into all three operating systems I'm trying to work with. Finally, I divide and reformat the remaining FAT partition into an ext4 partition and a swap partition, and install Ubuntu to that ext4 partition, with the bootloader installed to the same partition. This will break the Windows bootloader, as now the MBR and GPT tables are no longer syncronized. Ubuntu is also unbootable; attempting to chainload into grub2 leaves me at a black screen with a blinking cursor. The former problem is solved by booting into a LiveCD and installing and running gptsync. Windows is now bootable, but Ubuntu remains in 'limbo'.
The second method I attempted is very similar, but deviates in the last few steps. After installing Windows, I instead install Ubuntu 10.04 LTS, as I thought I might have fewer bootloader issues with that distribution (don't ask why; it was a lucky hunch).This breaks Windows Boot Manager, but this time grub2 throws me into the grub> prompt.I can boot into Ubuntu just fine using the set root/linux/initrd/boot commands, but my motherboard's Ethernet port is not detected by the OS, so I can't directly download and run gptsync. Once I do manage to run it, though, Windows is then also repaired.
Unfortunately, since I can't access the Internet, I can't do a distribution upgrade that way. Trying to upgrade from the recent release's LiveCD...well...doesn't upgrade, just overwrites. So I get the same black screen with blinking cursor problem. I've tried reinstalling grub2 through a LiveCD using grub-install both using the --root-directory flag and the chroot method.

I am an experienced Linux admin and have been using SuSE for many years. My development machine has had every version of SuSE since '02 and although it is a little old, is in good working order. (AMD
2400, 2 gig RAM, 160 Gig IDE disks - SuSE on disk 2) (OpenSuSE 11.1 with the latest kernel works perfectly. This install is on a spare HDD prior to doing a full install on my usual HDD.)
When I try to install SuSE 11.2 from DVD, the load kernel operation hangs at 97% (using both normal and safe kernel), however, I can install from live CD without any problem. I have tried the same DVD on a few "older" machines and had the same problem. I initially thought it was the actual DVD but re-burning has the same problem. I have also tried another DVD writer - same problem.
I'm running Ubuntu 9.10 and Windows XP on my system. After installing Ubuntu, it boots normally about once, and then the next time I try to boot, I have to wait a few minutes with it saying "GRUB Loading." I have read other threads about this that say that it is clearly a GRUB2 problem, and something about Windows overwriting something with the MBR; although I haven't booted into windows once in the process of installing Ubuntu (multiple times) or afterward. GRUB version 1.97~beta4.

View 9 Replies View RelatedI 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.

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??
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?

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.
