I reinstalled windows, which wiped out my boot partition. I then booted to a live CD, to attempt to reinstall GRUB. However the usual method and directions aren't working.

Had a working WinXp/Karmic dual boot system. Tried to upgrade Karmic to Lucid and my daughter rebooted the system during the upgrade. I decided to do a fresh install of ubuntu, leaving Windows in place and it succeeded until the end when it said it could install the bootloader, so I proceeded without. I meant to say "it said it couldn't install the bootloader, so I proceeded without.
On booting, Grub drops to the command line.
I get grub>, not grub-rescue>
I did ls in grub and it showed the partitions I expected
/sda5 is /boot
/sda6 is /swap
/sda7 is /
/sda8 is /home
I tried to follow the grub2 command line manual by entering
Code:
set root=(hd0,7) (success)
linux /boot/vmlinuz-2.6.32-24-generic root=/dev/sda7 ro (failed - couldn't find file)
so I'm now a bit stuck.
Here are my bootinfo_script results (by the way, sdb is just an e-SATA hard disc with nothing installed on it, I don't know why bootinfo thinks Windows is there. Windows is on /sda2 with some sort of backup/recovery partition on /sda1)

This is partly a note to myself for the future and a guide to anyone who experiences similar issues.
So, I had to reinstall Windows XP since my previous installation gave me a blue screen error due to reasons unfathomable. Naturally, this deleted the GNU Grub and I could not login to my Fedora.
I read that apparently booting from a DVD installation offers an option to enter the rescue mode. I did not have a DVD, I only had the LiveCD so I had to figure out a way to reinstall Grub from the LiveCD. The following method seemed to do the trick.
Run the LiveCD and open Terminal.

I have ubuntu 10.10 running on my HP dv5 pavilion laptop So today i tried to reinstall grub on my pc .. i removed grub-pc and grub-common using synaptic then booted up with a live cd of ubuntu 10.04 i then mounted sda11 to mnt using sudo mount /dev/sda11 /mnt sda11 being my ubuntu directory containing the /boot then i installed grub to it using sudo grub-install --root-directory=/mnt /dev/sda it reported as installation finished.No error reported then i unmounted /mnt and checked for /boot/grub/grub.cfg seems like the file is missing so are the files in /etc/grub.d/ reinstall my grub back

View 1 Replies View RelatedI have Ubuntu 10.10 and Windows 7 on my computer. After not booting into my Ubuntu partition for a while, I noticed that grub had disappeared, being replaced by the windows bootloader. I followed the steps here under "reinstalling from liveCD" and I was able to get a grub command line when I rebooted, but no boot menu. So I booted into Ubuntu and ran update-grub like the instructions say, and the output indicated that Ubuntu and Windows had both been successfully found and added to grub.cfg. But when I rebooted, I still only got the grub command line.
When the instructions had steps for if you had a separate boot partition, I used /dev/sda1 because it is marked by fdisk as being the boot partition. I thought that maybe update-grub was only seeing /boot on the Ubuntu partition and wasn't touching the boot partition, so I tried mounting /dev/sda1 as /boot, but after that grub didn't boot at all, it just goes straight to Windows and I haven't been able to reinstall grub even after following the steps again several times. How can I get grub back?
I've reinstalled win 7 (dualboot). Then booted with rescuecd and tried to fix grub.
Code:
$mount /dev/sda3 /tmp/b/boot
$grub-install --root-dir=/tmp/b /dev/sda
This gave ma a grub shell on boot. The prbm was that this was grub1 - v0.97
I ran a proper 2nd time
Code:
$mount /dev/sda3 /tmp/b/boot
$grub2-install --root-dir=/tmp/b /dev/sda
Now on boot I can spot grub loading and black screen with blinking cursos on top. ubuntu 10.10, separate /boot, uncrypted /root (which is probably the cause) Also I have deleted the 2 win partitions (sda1, sda2) and made a new one (sda1). The /boot is still sda3, can this be the cause?
I reinstalled winXP and lost grub loader. I have LiveCD with Fedora 10. How can I reinstall GRUB using this CD ?
View 14 Replies View RelatedI've restored a Clonezilla image of my Fedora 11 ext4 installation but realised that I hadn't backed up the ext3 /boot partition. I decided to create a Clonezilla image of the ext3 /boot partition from my laptop, as that has exactly the same partition scheme. I've restored that. I realise it may not work but it might save me reinstalling F11 from scratch. How does one reinstall grub in Fedora 11 given that /boot is on a separate partition? Booting from the F11 DVD in rescue mode, running chroot /mnt/sysimage and grub-install /dev/sda doesn't work.
View 4 Replies View RelatedIn drs305's standout article HOWTO: Purge and Reinstall Grub 2 from the Live CD, in the section where it says:
Quote: From the Live CD:
* If the Ubuntu OS cannot be accessed through the normal boot process (see above), boot a compatible installation CD/Live CD. The Grub 2 files are by default installed in the partition's /boot/grub folder and will be placed in this folder if the commands are run as instructed. (emphasis mine)
I'm not certain what precisely means "compatible" here? Is it using the same desktop (K/X)Ubuntu what is installed on the hard drive? Or the same release number (such as, in my case 9.10) or both or just ---well, you get the idea I'm sure.
I have Ubuntu 10.04 with file system EXT4 and dual booting with Vista The problem is I am about to reinstall Vista which will overwrite Grub 2 I know how to restore Grub2 with the Live CD I currently I only have a Live CD of Ubuntu 8.04 which doesnt support EXT4 neither Grub2 I am on a very limited INTERNET so I cant download the Live CD. A solution would be the minimal cd image but the download stall at 96%
View 3 Replies View RelatedI'm trying to re-install Grub2 on a dual boot (Win/XP & Ubuntu 10.10) system which will not boot. I am following the guide here:
Code: [URL] This guide explicitly states that the procedure will re-install GRUB to the Master Boot Record, overwritng whatever is there. However, the final step results in this warning message: "grub-setup: warn: Attempting to install GRUB to a partition instead of the MBR. This is a BAD idea....."
I guess I agree - that's not what I want to do. Where is the defect in the procedure and how do I overcome it? If I try alternative advice, available in the forums, by using the command
Code:
sudo grub-install /dev/sda
then I receive the error message
Code: grub-probe: error: cannot find a device for /boot/grub (is /dev mounted?) Looking at the mount command output, I think the required device is mounted.
I had Kubuntu 9.04 and Windows XP on a Dual Boot. I upgraded using the update manager to 9.10. (I know, I'm a fool.) The Kubuntu install stated freezing hard on startup, just after the GRUB OS selection screen, at a blinking cursor and otherwise blank screen. I'm pretty sure 9.10 will work great from a fresh install, but the live cd freezes after main Kubuntu boot screen and even Windows live cd only shows Windows partition. fixmb, fixboot, bootcfg etc. do NOT replace the grub as desired.

sda3 is my root partition, sda2 is the partition where all my media files are located. I mounted /dev/sda3 to /media/root and then I tried to reinstall grub with: sudo grub-install --root-directory=/media/root /dev/sda It came out with no errors, and then I restarted my computer. Grub started, but with a command line. It was the 1,97 beta-4 version. Since I'm quite unfamiliar with GRUB (or really technical linux stuff)
I dual-boot ubuntu 9.04 and windows 7. I recently reinstalled windows, and it wiped grub-legacy off of my MBR. Reinstalling grub shouldn't be tough, right, especially with clear instructions? Anyway, I can't get anywhere with the official instructions here: [URL]. The first issue is that the current live CD has no program "grub" in terminal. I dug up an old live cd, but I couldn't get anything with the directions:
Find where Grub is. If this gives a few different answers then you will need to find the correct one, perhaps by trial-and-error.
find /boot/grub/stage1
That command didn't find anything, nor did some similar commands found on google.
So I'm really at a loss. What should I do?
-Can I install Grub 2 on my MBR? Will that work with 9.04?
-Can I access my 9.04 install, copy files to Windows, and then just format the partition and clean install 10.04?
I got a system crippling virus on my windows installation. My recovery disks gave me the same problem. So I installed Win 7 enterprise using a disk my dad got from his work.

Could somebody please help me with this issue because I cant stand using Windows for anything other than games much longer.
View 7 Replies View RelatedI didn't get any responses to my question yesterday about grub with multiple disks
By "best," I don't mean with the most technical detail about each and every option. Instead, I'm looking for a guide that provides a step-by-step instructions about how to do some of the more common tasks, e.g.: configuring grub to work with MS Windows 7 and XP how to reinstall the MBR with grub after MS Windows' install program overwrites the MBR reinstalling the MBR from Fedora's LiveCD (without going through the whole install process) because I can't boot to my hard drive. configuring grub to work with multiple OS on separate hard drives
Again, I'm looking for a guide that starts with the basics about how to create a configuration file and write it to the MBR.
I have been following (200 instructions on how to do a clean install without losing settings.I used the command<sudo dpkg --get-selections > /home/user/package.selections>to create a list of installed applications.My problem is that the instructions to reinstall those packages does not work. The code given is<sudo dpkg --set-selections /home/package. selections && apt-get dselect-upgrade>.However when I try and run this code I am told that "--set-selections takes no arguments".So I need some revised code to reset the list of applications for re-installation

I have a dual boot system. I need dual boot as my dictation software is only available for Windows. In the future I am going to try a virtual machine, but dictation and audio did not work properly the last time I tried in VM. But unfortunately for now I have a dual boot machine with Vista and Debian 6. Unfortunately, I am going to have to reinstall Vista. Or to be more accurate I'm going to install the 64-bit version instead of the 32 bit that came with the computer. I have the 64-bit version that I no longer use from one of my other computers.
Anyway, I have to install Windows which will overwrite my grub2. Is there anyway I can make a backup or reinstall grub2 after I install Windows. I really don't want to reinstall Debian 6 squeeze. Can they make some sort of a backup of gurb2 before I do this. I checked out the Internet and I found something called Super Grub2. It apparently will allow me to boot back into Debain 6 so that I can install grub2 again. Assuming, Super Grub2 even works then how do I reinstall grub2 once a boot into Debian 6? Has anybody tried Super grub2, does it work? It's kind of hard to test it, with a working version of grub2.
I have an HP Pavilion m7480n PC with Windows XP installed on the C-drive. I successfully installed FC 12 onto the spare USB drive. When I rebooted the PC all I got was a blinking underscore at the extreme upper left position of a totally black screen. After a bit of experimenting I found that if I hit the F1 key during the boot process, go into the BIOS setup, do nothing within the setup, and press ESC to get out of the setup then the PC will go back into the boot cycle a second time. During the second time however a small text message appears with words to the effect "Press any key to enter GRUB..." after which the GRUB splash screen comes up with the choice for FC 12 or "Other" (referring to Win XP). At that point I can boot into either one.
