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 use Linux Mint, and I installed a linux-rt from the repository, but when I restart my computer no grub menu shows up. It just boots linux mint. How can I get it to show the menu so I can choose the real time kernel?
View 1 Replies View RelatedI'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.
what is the correct way to delete the kernel that is compiled by me?

I compiled my kernel, compiled scsi support into kernel, used the new kernel and initrd, the boot failed.Then ,i unzip my initrd, found that sd_mod.ko can't be insert, i added it manual, and reboot OK.so, why! in the kernel configure , the sd_mod.ko is set to <M> , but why it can't be found in initrd?

The first is I seem to have 3 GRUB installs. So whilst I update the one from my live session, the change does not appear in the boot up menu. I had installed 10.10 from a CD into a different partition (sda6), but that will not boot, so I have just deleted this and done another grub install and update. The kernel I am using has just been updated from 10.04 to 10.10 too, and it is this that I use and the Grub I have been working on (sda5).

View 1 Replies View RelatedOver 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 have been trying to build linux from source code and run it from my machine (intel platform).
Here's what I did:
Code:
I am using Grub2. When I rebooted the new kernel was in the grub list all right. But booting from that kernel fails with no errors or warning. The screen just goes blank. The disk usage indicator LED also doesn't glow which I guess means that the kernel isn't being read from the disk. I rebooted using my older kernel and it booted properly. Then, when I listed my /boot directory, I noticed that there was no initrd.img for 2.6.39. kernel in there, which I think is the problem.
I am testing my crash recovery strategy for my linux system and I am having trouble with GRUB. I am basically restoring my backup (i.e. tar) unto a different hard drive, but I am having problems getting the machine to boot without me having to type the GRUB commands at the GRUB prompt that is presented when the machine boots up off the new hard drive. I have tried to restore the MBR in two ways (the 2nd one is the one that gets me to the GRUB prompt):
1. Get the MBR off the original drive and write it unto the new drive (all via dd), but that did not work at all: the machine hangs right away during boot up. It seems to hang right at the point where the BIOS tries to read the MBR.
Code:
On original drive:
# dd if=/dev/sda of=mbr+part.bin bs=512 count=1
On new drive (new drive is now in place of original drive):
# dd if=mbr+part.bin of=/dev/sda bs=1 count=446 conv=notrunc
2. By using the FEDORA rescue CD, I installed grub unto the new hard drive as follows:
Code:
# chroot /mnt/sysimage
# grub-install --root-directory=/boot hd0
reboot and remove FEDORA CD Using the 2nd option above, I get the GRUB> prompt during bootup. I can then boot into the system by issuing the commands that are in the menu.lst file, followed by the "boot" command. However, I would like for those commands to happen automatically, just like in the original configuration. It seems to me that GRUB is actually finding all its stage files because I doubt the GRUB program (the one displaying the prompt) fits entirely in the 446 bytes it has on the MBR. So, it must be loading its stage 2 (and stage 1.5??) files from my /boot partition. However, if GRUB is loading its stage files off the boot partition, why does it not load/read the menu.lst/grub.conf contained in the boot partition also?

About a month ago, I decided to go deeper in my Linux knowledge. I've been reading a lot and found out that Arch linux would be my learning distro. As I was installing Arch, it was a pain at first but I really learned a lot which I would never ever learn with Mint. Now I decided to take a step further is which "compiling your own kernel".
MY PROBLEM:
Everything was smooth in my Arch for a 2 weeks until I decided to compile my own kernel. I currently have a Nvidia GTX 460 1GB card.
BTW, the method I used to install nvidia with 2.6.37 was
Code:
pacman -S nvidia nvidia-utils
and that worked with all of the .37 kernels (-1 -2 -3 -4) which was download from kernel.org.
When I compiled the .38 (using the same .config of .37), it just boots up to the terminal (not loading gdm). However, I could still login by typing my username and password. So I've checked dmesg of both .37 and .38 and noticed that the Nvidia driver is not loaded in .38.
I tried reinstall it by running pacman and it doesn't do anything. It was thinking of uninstalling nvidia and nvidia-utils but there are so many dependencies conflicts (like screensaver, compiz, etc).
Since, I didn't want to mess up my .37 install, I just grabbed an old HDD and installed from scratch again. This time, I compiled the .38 kernel first (without gui) and then installed nvidia nvidia-utils. It was the same problem.
With this observation, I'm concluding that the nvidia and nvidia-utils from pacman is not compatible with .38.
I've read that I have to wait for nvidia to release a driver that will be compatible with the .38 kernel. Is that true? Does it mean I have to wait for nvidia/nvidia-utils to be updated from pacman? How would I know when it is updated?
I've also read about nouveau, but I guess that is not for me because it doesn't support 3D.
Is there a work around for me to use nvidia/nvidia-utils with .38?
Is nvidia and nvidia-utils proprietary drivers? What is the difference with these two and the one you download directly from nvidia?
First of all, I apologize for the bombardment of questions. As you can tell, I'm so clueless on how nvidia drivers work on linux in general (since it was spoon fed by mint) and I really would love to learn about this is a deeper level. Could someone please explain to me (LAYMANS terms) how nvidia works (and possibly a solution to my issue).
EDIT: Additional info - I have a netbook that also runs arch. It uses an Intel GMA integrated video chip which I used "xf86-video-intel" from pacman and I believe since it is open source, it works with .38 fine. So does that mean if you use an open source driver, it will work with all other kernels?

I've reinstalled Grub to /dev/sda5 using the chroot method outlined in the Grub2 info page on this site, but it always results in the same outcome of ending up in the Grub cli. I can chroot that install and attempt a update-grub, but all i get is "cannot find list of partitions!" attached is the boot_info_script results.
