here it is: I tried installing grub from the Live CD to one of my hard disks (/dev/sdc) on a PCI to ATA adapter. I wanted to be able to choose which OS to boot from when the ATA adapter booted from the hard disk with GRUB on it, but all I get is a GRUB prompt. How do I make a normal GRUB menu on that hard disk with all my OS'es on the menu?
View 6 RepliesI recently installed Win7 on my machine and of course, that removed Grub and didn't install the boot manager. I tried to download EasyBCD but it doesn't allow me to select the appropriate partition for Linux so I can't boot into Linux. Is there a way to install Grub from the live CD Without having to completely reinstall Ubuntu??

View 9 Replies View RelatedI have an old HP PC with 2 drives: Primary (C = 20GB) and a slave (E = 60GB). I have Windows XP Pro OS (which I want to completely replace with Ubuntu). Ubuntu 10.10 is installed on E as a side-by-side (with XP on C). I am done testing Ubuntu and now want to completely replace the XP OS.Ubuntu is installed on E-drive as a partition. ISSUE: When I log on the PC goes directly to the GRUB menu but I get no option to boot from the Live Disk 10.10 during the boot-up.
HISTORY: I have tried (unsuccessfully) to remove Ubuntu from my E-drive by use of the uninstall function from Windows control panel. I have also tried to remove it using the manage/Disk Management process but the "Format" and "Delete" options are unavailable (grayed out) so cannot use that. I would like to do a complete clean up and fresh install of Ubuntu as my only OS.I have read and tried a number of internet articles / recommendations about opening BIOS and redirecting the start-up to the disk, but I do not get any option or any time during the boot to do that.
QUESTIONS:
1) How can I get my HP PC to boot from (recognize) the Ubuntu Live Disk (CD)?
2) Would a complete removal and clean reinstallation be a better approach?
3) And how can I remove Ubuntu from the partition on E (as I want to dedicate the C-drive exclusively for Ubuntu)?
This is my first post so please be patient. I am unfamiliar with this part of the installation process.
How to install grub in /sdb3 /media/{some-uuid} via Live CD?

Naturally, hiding the graphical grub screen on a regular installation is easy, by adding either "timeout 0" or "hiddenmenu" to menu.lst. But on a live boot, there seems to be no menu.lst - at least no accessible one.
Although, in some kiwi image types, you can specify boottimeout="n" in the image description's type element, it does not have the intended effect. Here is an example. The following type element's boottimeout attribute will invoke the first grub menu item instantly. Changing the value to zero, not only does not hide the grub screen, but seems to restore the default 10 second time out.
<type image="iso" primary="true" boot="isoboot/suse-11.3" boottimeout="1" hybrid="true" flags="clic"/>
Is there any way to hide the graphical grub screen in a kiwi live boot?

View 4 Replies View RelatedI'm running Karmic Server with GRUB2 on a Dell XPS 420. Everything was running fine until I changed 2 BIOS settings in an attempt to make my Virtual Box guests run faster. I turned on SpeedStep and Virtualization, rebooted, and I was slapped in the face with a grub error 15. I can't, in my wildest dreams, imagine how these two settings could cause a problem for GRUB, but they have. To make matters worse, I've set my server up to use Luks encrypted LVMs on soft-RAID. From what I can gather, it seems my only hope is to reinstall GRUB. So, I've tried to follow the Live CD instructions outlined in the following article (adding the necessary steps to mount my RAID volumes and LVMs). [URL]
If I try mounting the root lvm as 'dev/vg-root' on /mnt and the boot partition as 'dev/md0' on /mnt/boot, when I try to run the command $sudo grub-install --root-directory=/mnt/ /dev/md0, I get an errors: grub-setup: warn: Attempting to install GRUB to a partition instead of the MBR. This is a BAD idea. grub-setup: error: Embedding is not possible, but this is required when the root device is on a RAID array or LVM volume.
Somewhere in my troubleshooting, I also tried mounting the root lvm as 'dev/mapper/vg-root'. This results in the grub-install error: $sudo grub-install --root-directory=/mnt/ /dev/md0 Invalid device 'dev/md0'
Obviously, neither case fixes the problem. I've been searching and troubleshooting for several hours this evening, and I must have my system operational by Monday morning. That means if I don't have a solution by pretty early tomorrow morning...I'm screwed. A full rebuild will by my only option.
I had windows XP on my c:drive. installed ubuntu 9.10 on a 27 gig unallocated space. ubuntu ran fine. Then i boot to win xp and used a partitioning software to take back some other unallocated space. after it rebooted to complete the partitioning processes grub wouldn't load. So i need to re install grub from this ubuntu 9.10 live cd.i tired the following
grub(didnt work the first time said i needed to install grub so did : root@ubuntu:~# sudo apt-get install grub )after grub was installedgrub> find /boot/grub/stage1 Error 15: File not foundthe previous linux partition I can see in the Computer with the boot directory and is called 1000gb hard disk: 27 GB filesystem see screenshot.
So here is my problem:
I'm trying to restore the grub using a ubuntu 9.10 live cd. I have two partitions in my computer, and i used the partition that contained Vista to install windows 7. Now, i'm trying to restore the grub so that i can also boot ubuntu.

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.
I decided that I wanted to take Arch for a spin for the next week or so (I've had Ubuntu installed for a while) and so I thought the logical thing to do was to erase my partitions and start over with a new live cd...
Well.. that didn't work. I tried to do it from Disk Utility in OS X which succeeded in deleting most everything... EXCEPT grub is still in the mbr (or whatever it runs from through rEFIt). But all I see when I start up in the non-OS X partition is:
Code:
GRUB
At any rate, no Live CDs work, I can't delete the partitions from OS X (including after booting up from the OS X Install disk).
If I hit F1 I can get the "grub>" prompt. But I can't figure out how to launch a live cd. To my knowlege, there's not a "bios" for rEFIt where I can force it to boot from CD, is there?

View 7 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.

View 6 Replies View RelatedWhile 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.

The boot sector somehow got messed up on a friends computer while updating. I used to know how to do it with the old version, but now that they've updated it and changed everything , how do you repair the boot sector from a live-CD with Grub 2?
View 5 Replies View RelatedI 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.

In the message the author suggested to downgrade the grub package. How can I downgrade a package if I cannot load any kernels or a console? I have got a usb live, but I have no idea on how to downgrade a package from live usb.
I'm wondering if there is a way to remove GRUB from a live CD, then reinstall it?
I have three hard disks. What happened is, for some reason in the installer, it thought sda had the MBR on it. But in reality, sdb has the MBR. So when I rebooted, seeing as how I have installs of windows on sda and sdb, GRUB never appeared, and I got the windows bootloader screen.

This fix involves two steps. First one is to chroot into Ubuntu installation partition. Second one is to install the grub MBR (Master Boot Record). I am using Ubuntu Lucid 10.04 and Live CD also of same.

I have a netbook that dual-boots Win XP and Ubuntu 10.04 and accidentally hit the Win recovery mode in GRUB today, but quickly restarted without formatting or proceeding with any recovery. But upon reboot I just see: error: no such partition. grub rescue>
What I have tried so far: Boot to USB Live Disk... It won't, just goes straight to grub rescue.I do ls and it gives me (hd0) (hd0,4) (hd0,3) (hd0,2) (hd0,1) (fd0) error: fd0 cannot get C/H/S values.
set gives me
prefix=(hd0,5)/boot/grub
root=hd0,5
but if I try to boot it says unknown command so I figured I needed to find the right partition to boot from but I went through all of them with ls (hd0,4)/boot, ls (hd0,3)/boot etc. and every partition comes back "unknown filesystem".
got four partitions, one for media storage, one with ubuntu 9.10 32bit, one with crunchbang lite 9.04 64bit and one swap partition. The partition with ubuntu has been formated from ext4 to fat32 (with nothing on it, obviously). Whenever I boot up the pc now, I get an "unknown filesystem" error and a grub rescue> prompt. When I try to boot up a live usb image from my usb stick I either get a "linux kernel not found" message (crunchbang lite 32bit) or "initial menu has no LABEL entries!" error (gparted live usb) which changes to "Could not find kernel image: vesamenu.c32" after a couple of seconds. save my media partition or, more importantly, my crunchbang lite partition (which has one single important file on it, I'd love to recover). If this is somehow not possible, then I'd at least like to get my system usable again by succesfully booting from usb. I'm fairly new to using linux. I tried some grub-rescue commands, but not even the "help" command worked,
