Ubuntu Installation :: "Error Booting Operating System" - Sudo Grub; Root (hd0.0)...) Doesn't Work
Mar 1, 2011
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.

I have a dual boot windows XP/ubuntu 9.10 set up on one hard drive. Everything was working fine. The 9.10 install had been updated from 9.04. I recently had problems with the XP partition (XP basically collapsed) so I re-installed XP on the same partition it was on before. I then attempted to reinstall Ubuntu ( I decided I wanted a new 'clean' installation of Ubuntu as well). When I got to the partition function it refused to recognize that there is a Windows partition, or a previous ubuntu partition, but states 'No operating system installed' or similar, and offers the entire hard drive for installation. When I look at the partitions using Windows partition software the Windows and the ubuntu partitions are clearly in evidence. I have also tried to reinstall GRUB but it doesn't appear to exist.

I am trying to install debian 6.0.1a in an old COMPAQ 1255 (amd-k6, 160 MB ram, 4.3 Gbyte AT33.33 MB/s Cyl 6568 Heads 6 bytes per sector 512 HardDisk). I am using the netinstall CD_ROM , I just want the base system (the last option in the list you are presented) I got installed debian 5.0.8 , base package plus fluxbox plus a light browser plus a light pdfviewer, and I got really surprised what an useful system I got from such and old hardware.
With 6.0.1a everything goes well during the install process, the net is recognized, also the disk, formatting an partitions are created, apt-get configured, repositories contacted, etc. I only select base system (may be I am confused with the name, it is the last option in the list), and I select the install using the whole hard disk (i also tryed the install using a separated home partition but I had the same problem). I am installing the system in spanish, using latinamerican keyboard layout.
the installer then asks to take away the CD-ROM, I do, I reboot and then I got "GRUB Read Error Operating System not found". Just before the message, the machine search the floppy. If I press a key, I got the same behaviour, noise in the floppy, error message.
I can boot the CD_ROM in rescue mode, and I can select /dev/hda1 and get a console. i can do ls and cd and navigate the tree. It looks like everything is there, the /etc, the /home, all of the directories. if I do fdisk /dev/hda i got a warning because dos compatible mode is deprecated with option p of fdisk i got:
15 heads, 63 sectors/track 8944 cylinders. (different of the specifications?)
device boot Id system
/dev/hda1 * 83 Linux
[code].....
i can do less grub.cfg, and I got lot of information. I think this part could be relevant to the problem
insmod part_msdos
insmod ext2
set root='(hd0,msdos1)'
search --no-floppy --fs-uuid

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 was trying to edit a file requiring root permissions, so I used sudo. I typed the root password and it failed. This happened three times, and the process was ended. I then logged in as root (su) and was able to navigate to the file and make changes as root. Am I missing something? How would I edit the sudoers file such that this password would work? Or is there another way to log in to the sudo group to make these changes? How do I set sudo passwords?

I'm trying to install Ubuntu 10.04 (32 bit)on my laptop (where currently is installed the amd64 version of Ubuntu 10.04 that I've decided to remove because of some small issues).I've tried using the installation CD (the same I've used to install it on my desktop, so I know that is a working copy),but at boot, although I select to boot from CD, the Live version doesn't start and Ubuntu 64 is run as usual.I've tried to create a startup diskon a usb pen,there the live version seems to start but then Busybox 1.3 is loaded and there is an error with initfrm saying that no operating system can be found.I've been told to download the alternate edition, but I'm still downloading it,

I have a fancy new Quad Core Xeon machine here that I'm trying to install F10 x64 on. The installation went fine. When it reboots the first time, though, I get the dreaded Error Loading OS.
So I dug up my bookmark of the awesome Grub HOWTO here and followed the steps to install Grub manually. Alas, I get the same result after installing it. Even tried doing a makeactive (hd0) just in case, but no luck.
I did more searching and searched for "raid install" but didn't find anything helpful. So here I am... hoping somebody has some insight.

I just purchased an Acer Aspire 5050, and was trying to install Ubuntu on it for my mother. (No, I am not forcing it on her, she actually asked for it.) I burned a CD and put it in the drive, and it said Operating System not found. So I went into the BIOS and told it to boot nothing but the optical drive. Same error. I burned another disk with the same computer, and then another computer. Same error. (Hereafter referred to as "nothing")
So I went and purchased a 4GB flash drive from micro center. Converted my iso to img and DDed from my Mac, then set the BIOS to boot it. The BIOS recognizes the disk, but won't boot from it, giving the same error. So I thought: Fine, I guess I can't get _nix to boot, how about Windows 7? Put the disk in that I used to install on my laptop, genuine Windows 7 disk, nothing. I tried the Vista disk that came with the computer, also nothing.
Any ideas on how to install ANY operating system on this machine? I get absolutely no POST errors. I turned off Quiet Boot and looked, no errors there either. I would be fine installing any _nix based, it doesn't have to be an easy install. I can provide more information as needed, not a problem. I can't think of any more useful information at the moment.

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?

Accidentally I changed the ownership of all the directories under / to my own instead of root:root. Now I am unable to use sudo and many bad things are happening. Is there a way to revert the changes or change the permissions again to root:root or make sudo work ?

So I've been trying to install to an iSCSI target for the past two weeks and while the installation finishes, booting doesn't work. I get dropped to a shell after boot installation. I have seen some bugs on red hat bugzilla 705213, but don't know how to resolve it. I'm new to Fedora but really want to embrace the distro

I recently recieved Ubuntu 9.04 Desktop Edition CD-ROM through snail-mail after requesting a copy online and I want to install it on my laptop, although I wish to keep Vista which is on it now.
My laptop has a 250GB hard drive. Although when in Vista this is represented as two separate drives each of 110GB, (C or ACER and (D or DATA.
Using the CD, I start the installation and everything is straightforward and self explanatory, until I get stuck at step 4...
Where I am told by the ubuntu installer: "This computer has several operating systems on it." (I'm confused now, I thought it had one, Vista.)
Beneath I am shown a bar representing my disk space which is divided between...
I am given the option to use the entire disk: 'SCSI1 (0,0,0)(sda) - 250.1GB ATA WDC WD2500BEVT - 2', (and from the mention of 250BG in the name I'm assuming this is one disk and not the two separate drives named C: & D: in Vista.) ...along with a warning - "This will delete Windows Vista (loader), Windows Vista (loader), Microsoft Windows XP Embedded and install Ubuntu 9.04". (The aforementioned "several operating systems" obviously.)
But I wish to keep Vista, so I select the option to "specify partitions manually" and am brought to a screen named 'Prepare Partitions', where there is a table somewhat like this:
I am then given the option for "New partition table", and if I select any of the bottom four devices I can 'edit partition' or 'delete partition'.
Selecting the device /dev/sda3 (because it is the one that I'm guessing has no operating system data on it, judging by the previous screen) and choosing 'edit partition', allows me the following options...to create a new partition size, to select what I want to use the partition as. (There are also two options for formating a partition, which is a checkbox, and Mount point. These are both greyed out.)
When I look at the 'Use as:' option, within 'edit partition', the drop down box allows me to use the partition in the following ways:
- do not use the partition
- swap area
- NTFS
- FAT 32 file system
- FAT16 file system
- XFS journaling file system
- ReiserFS journaling file system
- Ext2 file system
- Ext4 journaling file system
- Ext3 journaling file system

I'm still not all confident using sudo, so if you could explain what I need to do in simple steps including the commands I would be ever so grateful. I need my Windows back 'cause while I'm perfectly happy on ubuntu at home, my boss at work thinks Linux is an exotic metalworking tool (or something like that).

I recently did a single boot install of Lenny-xfce on a Compaq Armada laptop. There were no errors and grub indeed found that Lenny was the only OS on the hard drive and installed itself on the MBR. My problem is that I'm getting an error 18 when booting the freshly installed system from hard disk. I booted into rescue mode and started a shell to take a look around. There are files on the drive and /etc/grub exists. device.map shows dev(0,0) as being mapped to /dev/hda. A search on the forum for "grub error 18" came up with nothing.

Will a Linux operating system lose data during a power failure as does a Windows operating system?
(If yes.) This has not come up before but I'm going to be doing some work I don't want to lose.
Could you either point me to a backup tutorial or give me the quick overview of preserving stuff with Ubuntu?

I'm having some trouble using sudo - it did work fine, but now when I try to use it, I have the following error:
I understand that I have to modify /etc/sudoers but need to have root access to do this. I am using a bootable USB (lucid) with persistent changes and am unable to login as root, because I don't know the default root password, and am unable to use sudo to change it.
The problem occurred after I had some corruption to the casper file system, so I booted into Windows, moved the casper-rw file to another location on my flashdrive, and used a 1GB backup filesystem to repair the corrupt one using fsck.
After booting up from the restored filesystem, sudo would no longer work.

I am having trouble getting FEdora 15 running on my MacBook Pro. I had Fedora 15 installed before on this MBP before, so I know it works. I basically followed the good old instructions of
1. Create a Windows partition in bootcamp (rEFIt was already installed from trying to get ubuntu running)
2. Boot from disk and install in Windows partition with bootloader on installed on the / partition
3. Install, reboot, and resync the MBR using rEFIt partitioning tool
4. Shut down the computer and start up on the parition you installed linux on
Now I get a grub error code...

I'm new to both Ubuntu and this forum, so please try to bear with me.I have a 500GB HDD with these partitions Screenshot.pngI'm currently using the live CD to boot because when I try to boot to this HDD it simply comes up with the error "Error loading operating system". It was working fine until I started reformatting a different drive with XP on it; since then it has had the error.As far as I know I need to reconfigure GRUB to boot to the correct partition, but I do not know how to do this.I know that there are already threads about booting/GRUB problems. I have looked at a lot of them but because no one has exactly the same problem as me I do not know what to do.

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.

I have ubuntu server 8.x which works Ok but the other day I changed the owner of some files "the directory /etc" from root me. Now a lot commands do not work like reboot and such. So I tried to put ownership back to root and I can't. I say I dont have proper privilege. Sudo also doesn't work. I conect to the server using ssh with putty. What could I do to fix the problem? Update to the new version? This server has been working really well for a few years. The reason I changed the owner of the directory to myself is so I could edit some config files from my windows machine using a FTP client like WinSCP.
