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 :: Repair GRUB 2 Using Live CD?

Sep 24, 2010

I have been trying to repair the GRUB 2 Bootloader by using the LIVE Ubuntu Ultimate 2.7 DVD.

Basically I've been unable to boot Linux Ubuntu Ultimate 2.7 ( due to a multi boot set up) & read that it is possible to repair the boot loader by re installing it from the live dvd.

I've already tried to load up the DVD & run the Terminal program - on the command line I type '# grub-restore' & the reply is GRUB not loaded??

I've tried other command lines that are on various other posts but non of them work.

Or are there certain Linux operating system discs that have the function to repair the boot loader from the live dvd.

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 :: 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

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.

Fedora :: After Rebooting - Screwed Up Grub - Can't Remember Terminal Command To Repair Grub

Nov 24, 2010

I created a new partition in Windows Vista which, after rebooting, screwed up Grub. I believe that I need to reinstall Grub and everything should be fine, and I remember reading the command to do this on this forum, but I can't find it. When I boot, I now get a black screen with white letters instead of the Grub boot menu. It says something about "Minimal Grub" at the top and gives me a prompt that looks like this.

grub>

I can boot the live CD and I have internet access with it, but I can not remember the terminal command to repair Grub. Can someone tell me this command?

Fedora Installation :: Repair Grub Through Grub-ubstall - /dev/dsa Doesn't Exist

Jan 17, 2009

I am trying to install my laptop in a triple-boot configuration with Fedora 10, Windows XP and Windows 7 beta. I did already installed them in that order. This is how it is layed out on the harddisk:

Now i want to use grub to present a menu at boot so i can select an OS. Because I installed XP last it boots straight into XP. I've understood i should be able to do the following:

All goes well until the last step (grub-install). It gives an error stating that /dev/sda doesn't exist, which is correct; It doesn't. I do have the "device" listed outside of the chrooted environment.

My question is: How do I get /dev/sda available in my chrooted environment?

Software :: Repair The GRUB From Fedora 11?

Jan 22, 2011

I'm going to be installing Windoze (because 3D graphics are still not there in Linux), but that will of course override the MBR. So how do I rewrite it? I just tried starting from the Fedora 11 DVD until it got into the 1st graphical screen, and then I tried to mount *any* of my Fedora partitions - I think it's made 5 of them (God knows why!!), but anyway,none of them would mount except /boot - kept saying "wrong fs type or superblock" etc. My plan was of course, to chroot my current Fedora partition, and then run grub-install, but of course I can't if the partition itself doesn't mount.

Ubuntu :: File System Damage Repair Or Reinstall?

Dec 11, 2010

I booted up Ubuntu after a couple weeks of downtime. I think it had just installed updates before I shut it down. It seemed fine. I started updating it, then it started giving me a bunch of errors about the root file system being mounted read only, so I had to reboot. I've heard that it does that if the file system is corrupted or there is a hard disk failure. When I rebooted, it kernel panicked on all but the oldest kernel which did a fsck and rebooted. Then I was able to get back in, but most of my panel applets are gone and cannot be restored, it fails to start x at boot with no errors and I have to start it myself from the command line, it is unable to do updates, samba is gone, whenever I update-grub to add Gentoo to the list, it doesn't stay there and the computer is really slow. I have backed up my home folder to another partition. Do you think I will be able to repair it at all or should I just reinstall?

Fedora :: Make LVM2 Indentifier Back To Ext3 Or 4 And Repair Grub

Jun 18, 2011

I've done a search thru the forums on a recent headache but couldn't find anything. now we all know that windows installations knackers the grub boot-up, and it becomes modus-operandi to repair the boot loader, with a live distro. however, in my current dual boot system (vista.sp2/fedora12), i've done a clean install of windows7 over the current windows ntfs partition. as standard, the boot menu would vanish. but when i put in the live-linux cd, gparted now shows the fedora partition (sda6) as LVM2. i'm somewhat of a neophyte with linux, but fedora12, suse11.2 and ubuntu don't seem to yet support this file system.

since i don't have critical data on the fedora partition yet, i usually wouldn't mind reformating this part', but the wireless chipset on my laptop cost a fortune on cups of coffee and beer to install, and in addition i used the fedora12 FEL spin and want to keep the installation intact. is there anyway to make the LVM2 indentifier back to ext3 or 4 and repair grub form there (without loosing the current partition kernal etc.)?

Fedora :: How To Reinstall Grub In F11

Jun 20, 2009

I'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.

General :: Use Live CD For Repair But Get Another System Has Been Detected

Jun 23, 2010

I want to use the live cd (Linux mint 9) to do a repair install on my system, but when I start, it says that it has detected another instance of linux and this must be removed before I can continue. I don't want to do this as I have a lot of data on this system and I don't want to lose it. The error occurred when I did a dist-upgrade and installed new kernels. Before I installed the kernels, a message came up saying the following packages are already installed but are no longer required. Use apt-get autoremove to remove them. I did this and now when I boot, I get as far as the five changing dots on the screen and it just stays there. I went into command line and ran apt-get mint-meta-main mint-meta-gnome, and at the end it came up with problem with /etc/utilities/desktop.

Fedora Installation :: Repair To The Grub Boot Loader To Boot Into Win 7 ?

I have XP, Win7 Pro and F 11 installed. Before I installed F 11, Win 7 boot mgr was working fine. I then installed F 11 and I went to System/Admin/bootloader to edit it and it wouldn't bring up the boot loader. In the attachment was the error msg. Now my only option when I boot up is F 11.

I do not have access to the Win 7 DVD only the F 11 install disk since I am on a fishing trip and need to use Win 7. How can I repair to the grub boot loader to boot into Win 7?
