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?
I have added to Debian Wheezy testing repositories. After a restart there is no desktop anymore just the wallpaper picture is visible but no desktop pop-ups.
When I want to install the desktop through recovery mode, I get an error message that it "can't fetch...repos". How I can repair /etc/apt/sources.list through recovery mode?
i am not able to start gnome desktop though most gnome applications work in icewm and xfce4 newly installed. the system config edit button i cannot understand what keys where to edit? how do we reinstall gnome fully? by the way my system is

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
I attempted to install Catalyst 10.11 for my ATI HD 2600XT and the system now only displays lines and a large block of pixels where the mouse would go. CTRL-ALT-F1 kills the system and does not provide a command prompt. This is a single installation, not dual-boot, but there is no Press Esc to access the Grub menu during startup so I cannot choose safe mode. I attempted to get into Recovery mode using the flash drive that I used to install the system and it tells me there is no Recovery kernel (I used the 64-bit Desktop installer, not alternative). Does anyone know an alternative to get into the Grub menu other than ESC during bootup? Alternatively, do I need to download the 64-bit Alternative ISO and create a new boot disk with it so I can access Recovery mode? Is there something else I'm not thinking of?
I'm having a huge problem right now and I could use some help deciphering what's wrong.I can't get my system to boot (see signature) and even the recovery mode is buggered. henever I try to boot, all I get is a flashing underscore. This is the same for both the normal and recovery modes Kernels. I've run the boot info script from a live cd and I've attached it to this post.
I have just installed 11.3 x64. The installation went fine and worked for the first few hours. I ran the online update tool, and now it cannot find grub unless the installation disc is inserted and I select the "boot from hard disc" option.
I have read about the problem of the root partition being back, but not sure that's it.
sda1 - swap sda2 - / sda3 - /home
There used to be a repair tool in the installation disks. I could not find that in this media. Is that still available?
This is an urgent problem. I removed my propreitary ati display drivers because I had to update them but I don't know what happened. Now I can't boot. The screen shows the Ubuntu splash screen but then the login screen does not come on. I get a blank screen. Worst of all, I had removed Recovery entries from the grub so I can't boot into recovery mode so easily. It's urgent. I don't want to reinstall with my exams a week away.
as Ubuntu is my only OS on this box.I had this PC running as a server for a few months with few reboots.I installed updates as usual yesterday, and hadn't changed anything configuration-wise since the last reboot. Well last night this server that I was running was moved to another Windows box and so I finally got to shut this PC down for the night. In the morning, I was greeted with an endless splash screen. It went on for 20 minutes without anything. I did update the kernel through update manager.
So what do I do? This machine has a 1TB HDD with a lot of very important data on it--reformatting is not a considerable option at this point. Which is bad because I don't know what else I could so when even recovery mode isn't working...
I had many problems with installing kubuntu 11.04 on my laptop HP Elitebook 8560p and after downloading different iso everything works well, but sistem freezeout and would not reboot also in recovery mode that would load untill Recovery menu when system won't responde.
After upgrading to 9.10 Karmic Koala, my Amilo Laptop (AMD64) refuses to boot. I installed GRUB2 which works fine for my WinXP ... and Karmic will boot in recovery mode.
When trying a normal boot, I get a black screen. CRTL-ALT-F1 yields just a blinking cursor. The system will immediately reboot when pressing CRTL-ALT-Entf.
When booting in recovery mode, I choose "Resume normal boot" from the menu, log in while in cosole mode and enter "startx" ... and the grafic environtment works fine!
Why does the system work in recovery mode, but does not start with a normal boot?

Here's some information on my system:
cat /proc/version
Linux version 2.6.31-17-generic (buildd@crested) (gcc version 4.4.1 (Ubuntu 4.4.1-4ubuntu ) #54-Ubuntu SMP Thu Dec 10 17:01:44 UTC 2009
I'm posting this in the "General Help" category, because it doesn't really fit in another one. Feel free to move this thread, if it's the wrong place. I'm having a problem with my Linux. Since today, my Kubuntu 10.10 (running on an Dell XPS M1530) doesn't but anymore. Neither normal, nor recovery-mode is working. I also tried out different kernels in the grub-menu without any success. The boot-process stops at:
Code:
... ... [2.115441] EXT4-fs (sda2): mounted filesystem with ordered data mode: Opts: (null) Begin: Running /scripts/local-bottom ... done. done.
I have GRUB on my laptop with Ubuntu and Windows 7. GRUB and Windows 7 seem to boot just fine, but recently, Ubuntu doesn't boot. My suspected cause is simply because I've often shut down unofficially. My laptop doesn't have a battery, and even the AC connection is awry, so as soon as an accidental disconnection or something occurs (because it too is broken), it'll essentially shut down.
I try booting Ubuntu, and it doesn't boot. I think I see that Ubuntu and the dots page, but it'll hang there (and I waited overnight). Immediately, I want to run an fsck, but I seem to be unable to, so I run Recovery Mode. I always get a forever loop of a bunch of stuff that doesn't make sense to me, but this is one thing that I always see (or something similar).
I started a thread over in installations and upgrades in which I was trying to upgrade from Ubuntu 10.04 to 10.10 using the upgrade manager. My computer froze in the middle of the process, requiring me to restart my computer. When I try rebooting Ubuntu, I get an error message "The configuration defaults for Gnome power manager have not been installed correctly" and then a blank screen. No mouse pointer, no cursor. It will not take me to the Ubuntu desktop screen. I've already found the sudo commands I can run to try and fix Ubuntu. They are as follows:
sudo apt-get clean (If the problem is not having enough free hard drive space) sudo dpkg --configure -a (If the problem deals with the upgrade installation process)
However, what I can't get is the terminal to come up to run these commands. In the other thread I started, someone mentioned that in the Grub menu, you can choose "recovery mode", hit "enter" to boot it, and it will give you a menu of options to choose from. However, when I choose "recovery mode" and hit "enter", I do not get a menu but instead 3 pages of data about my computer that ends with this:
"Begin: Running/scripts/init-bottom... Done. "
It gives me a blinking cursor at the very end but I cannot type anything and I cannot page up to see the 3 pages of data. What I am looking for is a way to get to the recovery mode menu OR somehow open up a terminal so I can run the sudo commands. My computer automatically logs me in, so I do not get a login screen and Ctrl+Alt+F1 does not work for me. Anyone know how I can open a terminal with only access to the Grub menu? Perhaps a BASH command that I can use in the command line that will open up a terminal? To summarize: My computer does not boot Ubuntu. I get an error message followed by a blank screen. It does not go into the desktop screen so I cannot choose Applications->Accessories->Terminal.
My Grub menu consists of Ubuntu and it's version, Ubuntu and it's version with recovery mode, memtest, and Windows XP (I have a dual boot system). In the Grub menu, I can select "e" for edit, "c" for command line and "enter" to boot either regular Ubuntu OS or Ubuntu recovery mode. "Sudo" commands are not recognize if I choose the command line for either Ubuntu OS or recovery mode. I have a Live CD for 10.04 but you cannot run sudo commands because you do not have access to root on the Live CD.
i'm a recent convert from windows and my first few days with this os have been great. to think i've been living in the dark all this time...
anyway, my question is about the boot screen in bios. normally it booted up thusly:
ubuntu-linux generic [...] ubuntu-linux generic [...] (recovery) memory thing windows xp
but today, the boot screen showed two instances of ubuntu generic, its recovery mode, and the memory thing (i forget what it's called exactly. do you know what i mean?). i installed the os only once.
I have a 8.04 x64 server installation that is receiving a kernel panic on boot no matter which kernel I choose even recovery mode.

I have built a new server, now I am trying to restore my db from mysql. I have a backup that is out dated, I was hoping there was a way to copy the files over and have them work on the new installation. I can boot the server with the installation cd using recovery mode, I can get to the hdd and mount a smbfs share from the new server. I have tried to cp the files retaining the permissions and get a permission denied error, but if I copy without retaining the perms they copy just fine and do not work.
I have setup the new server with very close to the same version of all software. I have built a new instance of my service using all of the same users and passwords. I then backed up the new db and moved it over and attempted to copy the old db over. I did not copy it straight to the mysql folder as I did not share that folder out. Any other ideas to get this db recovered? What about getting my old server to run again just long enough to get a mysql dump?
I have an encrypted file system and recently installed proprietary ATI drivers for my graphics card. The moment I did that, Ubuntu boots with a black screen. Now I'm attempting to get back into the OS to remove the drivers, but when I choose Ubuntu Recovery Mode from the grub boot screen, it shows some dmesg output and then the screen goes black. Whats interesting is it doesn't even ask me to decrypt the hard drive (like it normally does). how I can get back into the OS to remove the drivers?
I installed ubuntu 10.04 by wubi. It works perfect until I installed and ran "startupmanager". I find that I can't enter ubuntu, even in recovery mode. The screen keeps showing "rstslog main process ended, respawning [fail]" and other text
My friend asked me to look at their laptop as it was not booting up. I checked it and found that you could not even boot into safe mode. I have used a windows boot disk to try and sort any issues but this has not worked. The problem is he never made the recovery disks by the manufacturer so I cant reinstall windows. I can access all the files on the hard drive when running Ubuntu. So what I need to know is it possible to run the manufacturers program to make the recovery disks from Ubuntu.
This started a few days ago and I checked back through recently installed packages and nothing looks related. If I boot into ubuntu normally, plymouth looks a mess, but then things boot fine but while the mouse is showing and ubuntu goes about with connecting to networks and so on, but it doesn't register the and input from the mouse or keyboard. It will sleep if you press the power button, but its no more responsive after waking up.
If I boot into recovery mode, and use the failsafe graphics option then everything runs fine. Apart from 3D graphics being pretty slow, which I can kind of understand. I get the same behaviour on all of the last three kernels. I'm running the latest maverick on an HP 6715b. i386 version although the processor is 64 bit compatible. 2Gb RAM.
I'm sorry for this stupid question, but I have nowhere found it.I need to access to my USB disc from text mode (In Fedora LiveCD I see it and i can access /media/New Volume). In F12 runlevel 3 in mc I see it in /dev/disc/by-label as @Newx20Volume. But I don't know what is the correct path.
I got the blank screen when trying to install openSUSE 11.3 x64, so I was able to successfully install by choosing: Kernel (F6) > Safe Mode
Now I am trying to build my wireless driver, and I also notice that my touchpad is not scrolling. I had this OS installed in Windows 7 through VirtualBox before doing the clean installation, and I remember the touchpad scrolling.
I am thinking that by choosing Kernel Safe Mode to install openSUSE, that it did not install all the repositories, and it is why I am running into some difficulty.
what I need to do to fix my installation as if I had not installed in Safe Mode.
I tried to make Compiz work using the experimental 3D support of the free Nvidia driver, because I am suffering from a bug in the proprietary driver (click here for launchpad entry). The free driver I mean is the one that shows up as "Experimental 3D support for NVIDIA cards" in the "Additional Drivers" manager (note: for some reason, this option will only present itself when no proprietary driver is currently active).
Now the strange thing is: the driver does not provide 3d support, and behaves generally awful (lots of glitches and so on) when I boot my system normally. But when instead I boot from the grub menu into recovery mode, then select "failsafe graphics", and then select "restart X", the whole thing works perfectly! So now I am running the experimental 3d driver, I have compositing working, 3d animations on docky. Somehow, the failsafe boot sequence does something right that my normal boot sequence does not. When I reboot in normal mode, everything is screwed up again.
I have no idea what statistics about my system I should include here, because I really have no idea what could possibly be wrong. I am running 32bits Natty in Classic mode, on an Ahtlon Dual Core 4850e machine, with a GeForce 6150 LE graphics card. These are the normal and recovery entries in my grub.cfg:
Code:
menuentry 'Ubuntu, with Linux 2.6.38-8-generic-pae' --class ubuntu --class gnu-linux --class gnu --class os { recordfail set gfxpayload=$linux_gfx_mode insmod part_msdos
I've got a, as it seems to me, strange problem.I've inadvertently deleted my user from the group admin so I'm in the same situation of a lot of other users (read a lot of messages about it).My problem is that when restarted in recovery mode there is no way I can choose the 'drop to the root shell' or similar in the menu.The menu appears for a second and then I've got an empty screen. If I press a key I've been requested for a username and password that of course is not what I need.
After a large update of software I can nolonger open Squeeze. I get past the grub screen however before the gdm starts up the screen goes blank and stays that way. I have only one kernel showing on the grub screen.
I tried in Recovery Mode: Ctrl+Alt +F keys with effect and startx returns a blank screen, this is why I though to try loading another kernel to see if that helps. I'm using a Acer Laptop.
My question is: Is it possible while in Recovery Mode to load/install another kernel os that when I get back to the grub screen I have another kernel to try to boot into?
Ubuntu 10.10 doesn't boot at all. The liveCD only boots once every like 30 attempts, installing from liveCD froze, but the Alternate CD worked and installed ubuntu. Now when I try to boot into it using GRUB, it freezes at the beginning of the boot process.With normal boot it freezes at line: Starting AppArmor profiles Skipping profile in /etc/apparmor.d/disable: usr.bin.firefox.With recovery mode it freezes even before showing me anything
A little kinda like the liveCD, if I try like 30 times, it might manage to boot once in normal mode.That line keeps on repeating, the the xxx.xxx integer changes each time, and this goes on forever.I tried removing my floppy drive, but it didn't help.I tried to boot with fd0=noprobeThe one time it booted, when I restarted, it froze while trying to restart.
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:
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.
I have forget the root password of Red Hat Enterprise Linux 5. Please tell me how to recover it from the other linux account of the same version. I also want to know that after setting the new password did I have to repair the grub or grub will be as usual.
I accidentally chose the "recovery mode" and now i dont know what to do. What commands i have to enter to go back to normal ubuntu mode with graphic etc?
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.
