Ubuntu Installation :: Reinstall Grub 2 From The Live CD?

Dec 4, 2010

In 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.

Ubuntu Installation :: Can't Remove GRUB - Reinstall 9.10 From LIVE CD

Aug 17, 2010

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.

Ubuntu :: 10.10 Not Booting \ Reinstall Grub From A Live CD?

Mar 21, 2011

While trying to boot ubuntu, I noticed that it was taking a long time. A lot longer than usual, in fact.I then forced a restart on my computer, and noticed that Grub looked different - the resolution was weird.I then tried again to boot ubuntu, and got the following messages:vga=792 is deprecated. Use set gfxpayload=1024x768x24,1024x768 before linux command.mount: mounting /proc/ on /root/proc failed: Input/Output error.And then the computer seems to stay idle forever.Recovery mode is also not useful: I can only see some periodic messages about a failed command: READ FPDMA QUEUED.

However, I also noticed that grub showed something before it allowed me to choose which OS I would like to boot (Im running a dualboot configuration with Ubuntu 10.10 and Windows 7).I managed to get it:error: hd0, msdos6 out of diskerror: no suitable mode foundConsidering that I have no trouble booting into Win 7, and that I can actually access my Ext4 partition from there, Im trying to reinstall Grub from a Live CD.Heres the output of fdisk -l :ubuntu@ubuntu:~$ sudo fdisk -l

Disk /dev/sda: 250.1 GB, 250059350016 bytes
255 heads, 63 sectors/track, 30401 cylinders

Fedora :: Anyway To Reinstall Boot / Grub From Live Cd?

Sep 3, 2010

I installed the latest updates earlier today. Instead of restarting I just shut the machine down after updates were installed. now I can't boot into Fedora 12. I booted using the live cd and all my files seem to be in order except there is nothing in the boot folder. Is there anyway to reinstall boot/grub from the live cd? I do have a backup copy of a previous menu.lst.

Ubuntu Installation :: 10.10 And Win 7 - Cannot Reinstall Grub

Mar 29, 2011

I 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?

Ubuntu Installation :: Cannot Fix Grub After Win Reinstall

Aug 7, 2011

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?

Ubuntu Installation :: Why GRUB Reinstall Using A Partition Instead Of MBR

Dec 28, 2010

I'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.

Fedora Installation :: Reinstall Grub After A Windows Installation Deleted It?

Jul 23, 2011

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.

1. Find the partition where the Grub Stage1 is code...

Ubuntu Installation :: Grub Reinstall Went Wrong After Windows Wiped It Out

Jan 9, 2010

Some days ago I decided to reinstall windows, of course windows wiped Grub of the MBR. No problem. I booted of the live CD (9.10) and tried to reinstall grub, I had Ubuntu 9.10 installed before windows wiped grub. I tried the following tutorial: [URL] My fdisk -l output is the following: root@ubuntu:~# fdisk -l

Disk /dev/sda: 320.1 GB, 320072933376 bytes
255 heads, 63 sectors/track, 38913 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Disk identifier: 0x000f2962
[Code]....

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)

Ubuntu Installation :: 9.04 - Lost Grub Legacy In Windows Reinstall

Jun 19, 2010

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?

Ubuntu Installation :: Interrupted Upgrade Reinstall Now Grub Does Not Work

Dec 4, 2010

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)
Code:
Boot Info Script 0.55 dated February 15th, 2010
Boot Info Summary:
=> Grub 2 is installed in the MBR of /dev/sda and looks on the same drive in
partition #7 for /boot/grub.
=> Windows is installed in the MBR of /dev/sdb .....

Ubuntu :: Reinstall Grub2 From 9.10 Live Cd?

Feb 14, 2010

I want to reinstall windows to its partition on my computer, but I want to be able to restore grub2 afterwards. I use a lot of custom scripts in the /etc/grub.d/ directory on my ubuntu partition, so how can I reinstall grub to the MBR using those specific scripts? Just running "sudo install-grub" or "sudo update-grub" doesn't work for me (I don't know the exact problems, but I can't reproduce it right now). If there's a way to install just the defaults (without overriding my custom scripts!) maybe I can just do that, but I'd really like to put the live cd, run a few commands, and install those custom scripts to the mbr and be on my way.
