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.
I have two operating systems on my PC, 1- Fedora 12 2- Windows XP. when I re-install windows xp on PC yesterday, and reboot system, doesn't display grub menu to select a OS!! I tried to repair it with fc12 DVD 32bit, but it doesn't have any option for repairing grub (fc10 DVD had this option!!)
Code:
1. Resure install ...
go to shell and type:
2. chroot /mnt/sysimage
3. grub-install /dev/sda
4. exit
5. exit
and it without any error, said successfully done. when I reboot system and choose fedora from grub menu, fedora doesn't start and in black startup screen said:
Code:
SELinus target ...
take very times... dependence hard disk speed ....

View 5 Replies View Relatedmy ENTIRE hard drive now has user AND group permissions root. I can't start X and are having various permissions issues. although ive been using linux for a long time.
long story long, I did a debian netinst to my netbooks SSD. got everything EXACTLY as I wanted it, was very happy with my first go at debian but of course being a linux dork im always willing to tweak. I installed onto btrfs which I recently learned supports compression which not only saved precious SSD space (only 8GBs) but according to some benchmarks also improved performance. this was a boot option and would only start compressing new files. this, of course, could not be good enough. so I formatted my SD card btrfs, mounted it with compress option + my SSD defaults and copied over all files that weren't a mount (i.e. proc, dev, sys,...) however I forgot to copy permissions. so every file was copied with root:root ownership and I didn't realize this when booting to the SD card to verify things were working as I assumed ( never do this ) that getting to a login terminal was enough. So now I need to fix all permissions and I would really prefer it be without a clean install.
A netinst can take a dec amount of time and I had a lot of tweaking to do since I only used Xorg + i3 tiling wm. there has to be a way to fix this...I started trying to reinstall all the packages but kept running into issued where aptitude wasn't able to reinstall things like bash or perl-base, presumably bc they were in use or had incorrect permissions set
I forgot that Python is actually essential to Gnome and wanted to update to 3.1, and didn't realize my mistake until some of Gnome had been removed, then I Ctrl+C'd out. Now I can't even connect to the internet to repair my broken packages. I'm out of town for Mother's Day, but in the car it occured to me that I should have tried my Live CD.
As a side issue, is it alright to install more than one version of Python? I'm guessing so, so long as I keep track of which one I'm calling. I used apt-cdrom to update my sources.list appropriately so I could apt-get from the Live CD, but apt complained about locales. Now sources.list has strangely lost the cdrom line, but I'll put it back when I next boot to repair mode.
repairing the MBR on my raid array. I have three disks, each with three paritions:root (sda1 sdb1 sdc1) 59GB swap (sda2 sdb2 sdc2) 1.12GB grub/boot (sda3 sdb3 sdc3) 298MB I have been able to get this running and it has been working fine for several months. A few days ago, I installed 10.04 to a USB stick but did not disable the hard drives at that point and so the MBR was overwritten. If I leave the USB stick in, it boots fine from that stick. However now I can't get the boot from the raid array to work correctly. I can do the following:Load 10.04 from the Live CD install mdadm recreate the root partition using
Code:
mdadm --assemble /dev/md0 /dev/sda1 /dev/sdb1 /dev/sdc1
I can mount and view the files on md0 with no problems. It's not corrupted in any way. When I installed, I followed the directions to make each of the grub drives bootable. However I don't know for sure whether grub was installed on each partition separately or if it was installed on the assembled partition only. I have tried using
Code:
sudo grub-install /dev/sda3
and got warnings, something to the effect
Code:
Cannot find a device for /boot/grub
no path or device specified
Auto-detection of a filesystem module failed
specify the module with option '--module' explicitly
I have also been able to get to the grub rescue prompt but my keyboard (wireless USB) is not recognized and so I can't type anything in at that point.
When I hook it up to my Mac the hard drive shows up in Disk Utility but it can't mount it nor fix it. I don't have Diskwarrior (or similar programs) so I was wondering if I could fix it from my Linux boxes (xubuntu). So my question is, is there a program in Linux that could extract the data from the drive or (even better) fix it?
View 1 Replies View RelatedI have Ubuntu 10.10 installed on my computer (no other OS) and it wont boot up. I don't want to lose the files in my documents. I tried accessing them using a live CD and then copying them from the harddrive (home folder then 'richard' then documents then tried to open the folder but I dont have permission to and there seems to be no way of changing this.
The files are definitely on my harddrive but I dont seem to have a way of accessing them!
Is there anyway of either accessing them and copying them to a usb etc or repairing my installation of ubuntu without erasing the files in my documents? Opening in recovery mode etc wont work.
Basically, my Ubuntu 10.10 desktop crashed and now when I try to boot into it I get all sorts of error messages and then I get dropped into a shell - it can't find the device etc. I tried running fsck from the command line but it can't find it. My DVD Drive isn't reading properly so I have no way of running the Recovery software on there.

As the audio and video are intact and VLC, mplayer and xine can all play the files perfectly and ffmpeg can happily reencode the files.

I have got exactly this problem with grub [URL]
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 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.
When i do "sudo fdisk -l", the output is:
Disk /dev/sda: 120.0 GB, 120034123776 bytes

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 Replies View RelatedI 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.

View 7 Replies View RelatedI am facing some issues with my openSUSE 11.2 installtion. Yesterday i installed win 7 so the grub is now wiped out. I have also taken mbr backup in USB. I tried following things to make things work.[/HTML]
1) Repair using openSUSE DVD booted using DVD then automatic repair but it couldn't find any root partition. After showing error that no root partition found it crashes to a blue screen with advanced configurations from there i was able to use shell but cant see and mount any linux partitions. i tried mounting the root partition it gave the error :"please load module ext4dev before mounting" how can i install grub without losing my present installations.
2) Tried booting with Ubuntu & kubuntu 8.04 live cd .. both gave a error and refused to boot. then tried openSolaris which failed to detect the USB drive so couldnt restore the GRUB to /dev/hda.
After installing the recent kernel update and rebooting my machine I have found a horrible fact, my computer won't boot anymore. It seems my root partition was corrupted, and running fsck on it just sends me through a endless loop of "Ignore Errors {y}:" and "Force overwrite {y}:". I have already tried the use the repair system on the installation DVD but that doesn't do anything, the pop up asking if I want to repair the file system keeps coming up when I click repair.
View 1 Replies View RelatedI'm having difficulty repairing/reformatting a USB drive. I've yet to explore and get me on the right track. I'm sure I'm missing something obvious. I have a generic USB drive, 4GB, currently formatted FAT. I can't save files to it, can't format it using Ubuntu's Disk Utility. Attempts to format using Disk Utility return the following error:
Error creating partition table: helper exited with exit code 1: Error calling fsync(2) on /dev/sdb: Input/output error Yesterday I got fed up and tried to just zero the thing out using a dd command... ran it in verbose, the right stuff returned to screen, still no dice. I can't get it to a point where I can format it either using Disk Utility or mkfs.
Using redhat linux el5, when I had booted I had pbm repairing filesystem. So I run following commands
1. fsck -l
2. fsck
But I cannot solve the pbm. My pbm is I had important folder "backup" in root folder just I want to copy it in pendrive how to do it.
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?
After upgrading from 9.10 to 10.4 computer stop working. Booting stops on grub with a massage:

Is any way to restore grub without Live CD ?
