I would like to create a 10.04 lucid install on a reiser4 partition, every guide I have seen either only puts a reiser4 directory, or uses grub legacy. These are what the steps I believe I would need to do to accomplish this.
* Partiton my drive with
/(to have ubuntu installed), /(to have ubuntu copied over)
* install kernel source, tools ect... to build a reiser4 enabled kernel
[code]....
Im using parted when doing a new disk. If the disk is ext[234], xfs, jfs, parted displays the partition correctly, but if the partition was formated using reiser4 or btrfs the "File System" part there is nothing, like there is no formating done to the partition.
This is how Im using parted:ex.: parted -s /dev/sda print
Does anyone knows a patch to fix this issue?
If I boot on a live-CD, then enter in a terminal the following commands:
sudo mount /dev/sda1 /mnt
sudo grub-install --root-directory=/mnt /dev/sda
sudo umount /mnt
..does it install Grub-pc in /dev/sda1 ? even if Grub was already installed in /dev/sda1 ? Furthermore, are the 3 above commands equivalent to the below ones ?
sudo mount /dev/sda1 /mnt
sudo mount --bind /dev /mnt/dev
sudo mount --bind /sys /mnt/sys[code].....
I just updated my server from Ubuntu 8.04 to 10.04 and now it cannot go past grub, at boot time, it would "give up waiting for root device", asking me to check whether I gave the right "root=..." or if I should increase the "rootdelay=..." in the command line argument and end up with the initramfs.
The machine is a Dell Poweredge 2900 with a HW RAID controller (I hope that should not matter, but just in case...). I tried to follow the instructions there to make sure grub is setup correctly, but without any luck.
Below is the output from the bootinfoscript (while running on the LiveCD). Anybody has any idea what can be the problem or what I could do to debug this ? I am running out of ideas.

I am running Wheezy as my main OS in the first drive in my desktop. I use the 2nd drive for data. I am trying to add another OS to multiboot. When I ran grub-update in Wheezy, I am getting device letter for the root device instead of UUID in grub.cfg, in the os-prober section. Like this
Code: Select allsearch --no-floppy --fs-uuid --set=root 6ee49a8e-a619-49c7-9f66-51a5ca9a48cc
linux /boot/vmlinuz-316-x86_64 root=/dev/sdb3
initrd /boot/initramfs-316-x86_64.img
In the same file, UUID was used for the existing kernels.
Code: Select alllinux /boot/vmlinuz-3.2.0-4-686-pae root=UUID=c2eecf02-d427-4f2e-9fd0-9db61256cbac ro quiet
echo 'Loading initial ramdisk ...'
initrd /boot/initrd.img-3.2.0-4-686-pae
How can I get UUID instead of /dev/sdb3 for the 2nd OS?
As recommended, I'm creating a new thread for my configuring GRUB problems commented first hereWe are setting up a new version of a custom system, we are migrating to Ubuntu Karmic from another distribution (Slackware). Besides small differences between these systems (most of them from the most recent versions of software used by the latest Ubuntu, such as GRUB 2), it has been decided that the new system will run an union root partition using aufs and tempfs, basically, we are following the steps provided heree install the system to a new hard drive from an already running Ubuntu Karmic system, usingdebootstrap/chroot, we move the disk to another sytem, so we have to correct disk references, we are able to run this system and it behaves correctly the first time it boots, it bypasses the GRUB menu since there are no other systems detected. However, after halting the system and booting it, the GRUB menu appears with a new "recovery" option, we've managed to remove this recovery option usingGRUB_DISABLE_LINUX_RECOVERY=trueBut then, the GRUB menu appears again, this time with only one option to boot: our system installation. But when this GRUB menu appears, it has no default timeout and so it stays forever unless ENTER is pressed to boot into the selected entry.
The main problem is that we are unable to configure GRUB inside the new installation because it always returns this message:grub-probe error cannot find a device for /If we boot the system "normally" (mounting root to a normal partition), we are able to configure GRUB properly, but it does not behave the same when using the union file system as /We are only looking for a way to bypass the GRUB menu and boot our system, do you have any advice on how to properly configure the GRUB menu for our system
The problem after couple installations (10.10 --> 10.04 --> 10.10 --> 10.04-3) is that system goes to "busybox" after complaining about missing root device. I already have come to conclusion that this problem could be solved by telling the system that the root device is at sda1. However, I'm not able to start grub (by pressing "ESC") at boot before problems start. I'm able to start live-cd and I tried to install "over" the old one (same partitions without format, same username). No luck.
And in the busybox /proc/modules is empty for example. And the grub has worked with previous installations.
After I installed Linux OS(for example:SuSE10,redhat5),the [root] parmeter of [kernel] in created grub.conf seems that sometimes it's defined to device name.sometimes it's defined to Label or sometimes UUID. So ,I want to know what is that relative to? Hard disk type or OS version or both?

I'm trying to manually boot (from the GRUB console) into a system set up as follows: crypt partition -> LVM -> root LV, and I'm having some trouble figuring out how to do this from the GRUB console.
I have successfully manually booted a system which is set up as just LVM -> VG -> root LV. All I have to do is load the LVM module. In GRUB, that partition shows up as (hd0,gpt5). Once I load the GRUB LVM module, I can see the logical volume within the LVM as well. (My volume group name is "caesar", and the single logical volume is named "root".)
Code: Select allgrub> ls
... (hd0,gpt5) ...
grub> insmod lvm
grub> ls
... (lvm/caesar-root) ...
It's fairly simple to manually boot:
Code: Select allgrub> set root=(lvm/caesar-root)
grub> linux /vmlinuz root=/dev/mapper/caesar-root
grub> initrd /initrd.img
grub> boot
Where I am having difficulty is in trying to insert crypt before LVM. I can set up such a scheme, and put a minimal installation on it, without issues. It's booting into it upon reboot that I can't figure out. Once I load the GRUB crypto, cryptodisk and luks modules, I can mount the crypto partition:
Code: Select allgrub> ls
... (hd0,gpt5) ...
grub> insmod crypto
grub> insmod cryptodisk
grub> insmod luks
grub> cryptomount (hd0,gpt5)
Attempting to decrypt master key...
Enter passphrase for hd0,gpt5 (<long hex string here>): <type my password>
Slot 0 opened
grub> ls
... (crypto0) ...
At this point, GRUB sees the crypto partition as (crypto0). But the GRUB LVM module doesn't see "inside" of the crypto partition, so I don't see the root logical volume within the LVM listed; all I see is (crypto0).
Code: Select allgrub> insmod lvm
grub> ls
... (crypt0) ...
Setting it as root doesn't work:
Code: Select allgrub> set root=(crypto0)
grub> ls /
error: disk `crypto0' not found.
So, How do I get GRUB to "see" LVM inside the crypto partition?
I'm currently setting up a dell server with hardware raid 1 on sas 6r. i got 4 sas installed on the server and configured to raid 1 as stated below,
array 1:
slot 0 & 1
array 2:
slot 2 & 3
during the installation, the installer detect the array 2 as sda and array 1 as sdb.. so i proceed with installation on array 2. after completed the installation, the first reboot lead me to a 'grub-rescue" prompt. by following the guide at url Mode, i've noticed that the boot folder has changed to (hd1,1), which i believe it has changed to sdb1. default root device shows that prefix=(hd0,1)/grub.
I installed 10.04 (clean install) on a 250G drive (partitioned to 107G for the system files). It was working fine, until I wanted to install Window$ for the use of Adobe stuff. I popped the Windows XP disc in, it loaded its files, then I tried to choose a partition for installation. There was an error saying that I can't do that, and needed to delete a partition blah blah. I thought it was too much trouble, so I quit and just wanted to use my 10.04. Booted, and it says "Error booting operating system" I WAS SHOCKED.
I tried to install grub (but don't need that right? I DO NOT want to dual boot now), but the usual method ( the sudo grub; root (hd0.0)...) doesn't work ,because something like "stage1" is missing. I tried many methods by still the same error. The reason I do not want a clean install is that I did many fixes on my 10.04 so that it would work with my EeePC 1001pxd, and I do not want to go through that again. I will be checking my email frequently on other computers if I have a chance.
In regards to other distribution cds: I'd like to learn how to install a 'root' and 'grub' boot loader so that I can cleanly install other distributions. I'm new to the file system. Could I make a bootable usb with simple installers? or command line codes?

my question is how to get grub on sdb9 like it was on etch.is there a trick or did i miss a prompt? on another note, that bug where the format hangs if you try & install over an old system is a little irritating. can't believe it hasn't been fixed.

I have one harddrive and a DVD drive. In the bios, the harddrive is mentioned first. So (hd0,5) should point to the /dev/sda6.
BUT when I start my computer, it returns to the grub prompt. The command root gives: (hd0,6).
Why? It should be (hd0,5).
At the grub prompt I enter: root (hd0,5) and configfile /grub/grub.conf and the computer boots fine to fedora.
How can I tell grub use the correct partition?
Because I am using one of the new WD disks I am trying to aling my root partition with the real sectors, as described here:[URL]31So I copied all files to a temp location, deleted my partition (/dev/sda3), recreated it a few cylinders later (same name) and copied the files to the newly created partition.

I tried Alt+CTRL+F1, F1 or Shift, none of those gives me Grub screen.

Yesterday I've updated my system from 11.2 to 11.3, fllowing the guide at SDB:System upgrade - openSUSE . Everything went fine (except an error during the installation of batik) but after reboot I got a grub error:
And I couldn't boot
After a CD boot, because I didn't want to try the OpenSUSE 11.2 entry, I saw that the entry for OpenSUSE 11.3 was wrong, see below the entries for 11.3 and 11.2:
Code:
And of course it worked and my updated system works fine
First upgrade to 11.3 no problem. Then I got a disk issue. so got an old 80 gig sata drive, config new partition table, format etc. Install perfect as ever.
Then grub failed ....no grub menue.
I changed to MRB boot. this worked but initrd takes a long time and sometime hangs ?!? What could be the issue ? Harddrive?!
I just noticed, on both of my CentOS 5.3 servers, within grub, root shows (fd0)device.map = (hd0) /dev/sda and nothing else.
