Fedora :: Boot To Grub And Recovery Root Password

Jul 29, 2009

I am new to Fedora. I know my top probably already been posted somewhere but I just could not find it. I just installed Fedora 11. But my root password does not work (I guess was my fault to type wrong in the first place or some type of short term memory lost). I looked at the root password recovery procedure which involves select single user at GRUB page when booting. But for some reasons, Fedora 11 does not boot into GRUB. I tried Alt+CTRL+F1, F1 or Shift, none of those gives me Grub screen.

Ubuntu :: Repair MBR Without Mess Up The Windows And Recovery Partitions

May 11, 2011

This post is a follow up to this one: [URL] My computer is an IBM R52 running Windows Professional (previously dual-booting with Ubuntu 10.10, but that's gone now, and I don't dare reinstall it until the HDD partitions and mbr are properly working again). I think that the shred command mentioned there simply messed up my MBR, and maybe my partition table. Here's the partitions on my HDD:

Code:
Disk /dev/sda: 60.0 GB, 60011642880 bytes
255 heads, 63 sectors/track, 7296 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disk identifier: 0x7e93bd30
[Code]...

My question is, is it safe to use something like SuperGrub to repair the MBR? I really don't want to mess up the Windows and recovery partitions. I've done plenty of research on this, but am not confident until someone says that it works in my case.

Ubuntu :: 10.04 Repair / Boot A Recovery Mode From The Install Disc?

Apr 25, 2010

So I have been messing around with the new 10.04 and I managed to screw it up. When I started to log off, I closed the lid to my laptop so it would hibernate, but instead the screen went black and I could only see the cursor. It stayed like that for several minutes so I shut it down manually. When I booted it up again, it froze on the splash/loading screen and I haven't been able to boot it since. I've tried to boot in recovery mode, but I think my campus internet interferes with the downloading of the necessary files from the internet. Is there any way to boot a recovery mode from the install disc? Or am I SOL?

Ubuntu :: Finding A Free Diagnostic / Recovery And Repair Software?

Apr 28, 2011

I have several CDs of diagnostic and recovery software (most of which are dated) but never seem to have them around when i could use them the most. Then it hit me: use a flash drive. i usually carry two flash drives around with me, so i loaded one 4GB with diagnostic/repair tools from PortableApps.So far I have CCleaner, John the Ripper, Recuva, an antivirus, and SIW (System Info. for Windows). I still have plenty of space left and was wondering what you all's favorites were, or what i might add. I'm looking to have somewhat of a suite, something for any occasion (within reason, of course.)I think everything right now i have is PC-based. i just want a suite of tools in case anyone has a non-hardware issue.

Ubuntu :: Recovery/repair - Will No Longer Boot After Removing Packages?

Jun 17, 2011

OK as a recent Windows to Ubuntu convert I made a stupid mistake and now would now like to recover my OS, particularly my files.I had happily been running Ubuntu 10.10 but then used Synaptic to remove Python 2.6 (I was having trouble running Python 2.5 with both installed), I selected to remove Python and all it's dependencies (a bad move as I realise now, as it was quite a dependency list in the end!).

I was left with a semi functional desktop, some things worked but many things were broken / unavailable, neither Synaptic or even Terminal would work to situation.I tried rebooting in the forlorn hope that I would get some recovery options, but it would not boot, boot starts, gets to grub (top left flashing cursor), then that disappears and I am presented with a black screen and nothing then happens. If I then do a hard power down the screen very briefly shows some text (something like enter password) as it shuts down.

Subsequent boot ups just do the same thing. If I boot with an installation disk and move forward to the partition step the original partition is shown as in tact.So, my main question is, is there a way of recovering my OS without the use of low level disk recovery utils (which may be a bit painful and long winded). e.g. what happens if I install 'over the top' of my original installation, will my file system be in tact

General :: Asking For Password In Recovery Mode

Sep 15, 2010

I logged in recovery mode via grub, it shows several options: like, resume normal boot

When I enter the resume normal boot it shows something like this:

xxx login:

password:

And I entered my root password which I need for the command "sudo -i". But it shows incorrect password, why is it so?

Same thing happens with dpkg option also? Why is it so, I dont have any other passwords for my machine?

The new GRUB2 was supposed to configure itself from the old grub, but got the kernel image partition wrong.I have booted from Knoppix live cd, but need to write to system files. I have searched, and found several suggestions that apparently work on Win machines, but RO permission for root on Linux is a harder nut to crack.

General :: Windows Vista Password Recovery Using Knoppix?

Jun 6, 2010

I am new to knoppix. I actually have never used it. I was under the impression that I could change or recover my password on Windows Vista. I only have one user and it is the administrator. I am not exactly sure why it is no longer working. It is on a laptop and I have let others use it at times. don't know if someone may have changed when it was open at work or something. Every time I boot up and my user account comes up. I put in my password and it looks like it will log on but then comes back and says wrong password. I did see a way to do it with Windows 2000, and XP. Will that also work with Vista?

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?

General :: Recovery - Reinstalling GRUB On Linux Netbook?

Apr 4, 2011

I have a distribution called Easy Peasy on my netbook, it's Ubuntu-based.Today when I started it up it told me 'grub corrupt'. On subsequent start-ups it displays 'unknown filesystem.' I'm given a prompt labelled 'grub-rescue>' but I can't get any commands to work I've tried booting off a Live CD of Easy Peasy. That works fine, but I can't get to my files. I've tried using a program called photorec and it can recover files from the drive but it dumps out gigs upon gigs of unlabelled files, many of which are things like system files or web browser cache -- I only have a few dozen text files I actually need, so this is pretty unworkable.

I'm trying to reinstall grub, which I understand to be part of the booting process, but I've had no luck; any set of instructions I've followed has inevitably run into some error or a step I don't understand.How can I get at my files in an easy to recognise way (such that I can navigate the original directories and get what I want)? OR

How can I easily reinstall grub such that I can just use the system like before without having to reinstall everything and lose my files?I think my drive is sda or sda0. In grub's device.map it's called hd0.

General :: Deleting Vista Recovery Loader Shown In Grub For Ubuntu 10.04?

Jun 18, 2010

I have 3 hard drives and have Ubuntu installed on one (sdb), had windows vista installed in the other (sda) and use the other (sdc) as a back up/extra space. I just deleted the windows vista partition and formatted the hard drive (ext4) and now just use Ubuntu, however, in the grub boot, vista and recovery is still showing up. How can I clean the grub up and delete these entries. I've searched all over the place, googled like crazy and all I can find is how to get rid of grub or reinstall the MBR of vista (etc). One more thing, how can I permanently mount the new empty hard drive in Ubuntu so that I have access to it all the time w/out having to mount it.

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.

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 Installation :: Missing - How To Repair Grub File

Mar 2, 2011

I have installed windows 7 back to its former state in after foolishly messing around with some installation options in an Ubuntu install (this caused windows to disappear, and me to repair it). In *repairing* windows, I overwrote my grub file and the boot options for Ubuntu, so that it looks something like this:

Disk 1: Primary Partition - Windows 7
Disk 1: Secondary Partition - Windows 7
Disk 1: Secondary Partition - Free Space ( this is where I have Ubuntu installed)

How can I repair my grub file so that I can boot into my Ubuntu installation?
