I'm running Windows 7 on my desktop (But Ubuntu 9.10 on two laptops), and I have an odd problem.I backed up my system from one HDD to another HDD, and in the process the MBR of the destination drive got fouled up and now sees Windows Vista and Ubuntu (even though I never used anything Ubuntu - I assume the backup program used an ubuntu build).Is there any way No, I know there is. I had the answer once but lost it.HOW do I manually edit my MBR to remove the Ubuntu reference and rename Windows Vista to Windows 7? Please note Ubuntu was never dual booted, let alone installed at all, on the HDD in question.
I want to practice restoring the grub, before any emergency occurs
I plan to use the following thread: Grub/XP/Vista Bootloader - Ubuntu Forums
I would be grateful if someone could tell me an easy way to damage the grub. For example, re-installing XP always damages the grub, but I'm sure there are quicker ways to do the same thing .
I was running a somewhat standard install of Ubuntu 9.10, when my drive got pushed into read-only mode,It took an hour or too, but eventually finished. However, now that partition is unbootable, and upon attempting to boot into Ubuntu, it complains about "libsepol.so.1" as missing and starts a recovery shell. In this recovery shell, only certain tools work. ls complains about "libacl.so.1", and the filesystem is still read-only. It completes, much quicker, but the system remains unbootable. I could probably boot into the Ubuntu live-cd to get read-write access, but I wouldn't know what to do.I don't know how I would go about reinstalling the base Ubuntu packages without write access to the hd, or through the live cd.
I'm dual booting Win7 & Ubuntu 10.04 on a Gateway NV78 series laptop, and while on the Windows side, the Gateway Update Manager asks to update my BIOS. If I allow it to do so, will it mess up Grub? For bonus points: how could I fix Grub if the BIOS updates does damage it?
I was in Ubuntu when I dropped my laptop, which resulted in a cracked screen. I loaded Windows (Vista), and found it and the files to be unharmed. On my attempt to load Ubuntu, it takes me to a GRUB screen, where it gives me a default message about GRUB. If I try the command "exit" it replies "No bootable device -- insert boot disk and press any key. It's installed on the same hard drive as Windows (dual boot setup), and Windows works fine. I do have files I would like to get off of Ubuntu (if it is unrecoverable),
<CPU Performance Indicator> Can it damage a laptop in the long run to have it on Performance rather than a lower speed like "Ondemand" or "Powersave"? My laptop runs a lot better with "Performance" rather than something else, but I don't want it to suddenly die or get overheated in a couple of weeks or months.
extended my ubuntu partition with a free space that I had on my NTFS partition. It did get any problem. However, today I couldn't boot into ubuntu ( It was loading for about half an hour ). then I reboot and I got some GRUB error, so I boot into live cd to repair the grub but then unfortunately I found out that my Linux partition is damaged.I some how managed to repair it but the only folder that is there is "lost+found". also there is written 62.8 GB free space, but this should be 112GB (unless there are some hidden files that i can access to )
I was running a somewhat standard install of Ubuntu 9.10, when my drive got pushed into read-only mode, so I switched to tty1, ran /etc/init.d/gdm stop, and then ran fsck -y /. It took an hour or too, but eventually finished. However, now that partition is unbootable, and upon attempting to boot into Ubuntu, it complains about libsepol.so.1 as missing and starts a recovery shell. In this recovery shell, only certain tools work. ls complains about libacl.so.1, and the filesystem is still read-only. When I try mount -rw /dev/sda1, it complains about libsepol.so.1 again. I can however still run fsck. I tried running it with fsck -p -f /, and it completes, much quicker, but the system remains unbootable. I could probably boot into the Ubuntu live-cd to get read-write access, but I wouldn't know what to do. I read an interesting suggestion here, but I don't know how I would go about reinstalling the base Ubuntu packages without write access to the hd, or through the live cd.
I feel a little awkward in this Control Panel: first time user. I installed the latest version of Ubuntu yesterday. All went smooth until I got to installing printer drivers. The setup went online and my system froze...everything froze. I had to do a hard reset. The printer installation went smooth the second time. So far this is the only problem I've had. No details needed. What I was wondering is if there's any way to check if the hard reset did any damage.
I have a P.C. with Windows XP Pro installed and now I want to put Ubuntu on the H.D. Will the partitioning of the H.D. damage the Windows OS meaning a reinstall of Windows. If it does then I may be a bit stuck as I do not have the Windows install disc. Windows XP was put on the machine by the vendor.
I installed Ubuntu 10.04 LTS currently. This is my first experience with Linux and it was installed together with Windows XP on my laptop, a Compaq nx6320 (HP). After first running Ubuntu and then Windows the MBR (Master Boot Record) on my hard drive was damaged and I couldn't start my computer again. All my information and work gone? MBR and Grub can of course be recreated and things don't need to be so bad. You maybe will reinstall Windows and Linux and destroy all your data..
I can temporary fix my system until the problems is solved. The latter will probably be a better Grub(2) that can protect it self from being destroyed by Windows or any other code that write data to MBR. From different forums I can see that many people already is very upset and disappointed with Ubuntu because of the actual problems. Can Ubuntu and its supporters afford this to go on much longer?
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?
I have my home partition installed on a SD memory card, this memory card was damaged beyond recovery, already bought a new card but i dont want to install the OS all over again.
I have ubuntu installed system with dual boot windows xp.I need to enlarge linux partition. I have a free disk in windows partation. I need to add some diskspaces to ubuntu part without any damage. I mean I would like to use my system as before.Windows and Ubuntu. Is there any free software that does?
I have a new lenovo thinkserver hardware. I was configuring my newly installed kernel (slackware 13.1 - kernel 2.6.33.4) maybe to weeks now. I was testing the configuration of the kernel parameters.Suddenly out of the blue my BIOS started to report memory error. I have 6 Fully buffered memories in pairs. Four has no advanced ECC and two supports ECC.It is possible to damage the memory by some wrong kernel configuration???I cannot believe that this is possible but I cannot see any other explanation how can a two weeks old hardware get wrong.
I know now: I overwrited the mbr with a totally wrong one, and I have no backup.So far as I can recall, I had two primary partitions; the first one for xp, and there were several logical volumes for linux in the second primary partition).None of these partitions are found now, grub reports "Error 22" with the wrong mbr.Can the mbr be corrected/recovered somehow, in a way that all of the original partitions show up again? I think, the partitions themselves are not damaged, since only the mbr was overwritten.
I suppose a fixmbr command from the recovery console of the xp installation CD would fix the mbr and make the xp system in the first primary partition bootable. Am I right? How about the second primary partition; would fixmbr find that too? (Sorry for the silly questions, but I do not want to commit more mistakes, especially irreversible ones.)
My computer started acting flaky this afternoon and by the end of the day, became completely inoperable. When I reboot and login, I'm given only a Terminal window. I'm running Ubuntu 10.04 LTS, although the Lynx is not very Lucid at the moment!
1). First sign of trouble was yesterday when I was running Win XP as the guest on Virtualbox. XP became unresponsive - at least the mouse could not push any buttons. I had to do a cold shutdown by right-clicking the "close" button at the tab on the bottom Gnome panel. This problem repeated itself today.
2). I attempted (and I thought, succeeded) in upgrading OpenOffice.org to version 3.3. OO seemed to work fine, but after this install I started seeing problems.
3). I attempted to remove Pulse Audio via Synaptic, but instead of removing only Pulse, pieces of software started flying out of the machine (so to speak) at an alarming rate. It happened too fast to count them all. I think the entire desktop is gone along with many individual programs (such as Kaffeine, being one that I noticed).
Currently, I'm running a backup copy of Ubuntu that I keep on a separate hard drive on the same machine. I can access my files from here, and yes, I've backed up my home folder from the other disk!
When I reboot to the damaged system and I get the terminal window, how should I repair the damage? How do I find out if the damage resulted from broken or missing software, or both? Should I try to load Synaptic from the terminal, and if so, how is that done?
I would like to test alphas (of distros and packages), but without doing so from my everyday environment.Obviously, frequent backups are essential for maintaining important files.Apart from that, what other measures can I take to prevent catastrophic data loss?Could a well-designed partition structure the chances of an alpha blowing up data on other partitions?
I have pen-drive and hexEditor, I made my very simple boot sector and I want to boot it from pendrive. Firstly I have to format it, is setting all bits to 0 on pendrive dangerous? or are there any bits that are reserved and I should not touch them?
Much to my consternation, my video card blew a few capacitors. A local computer shop said that they tried a working PCI Express card, and the video was still not working, so they concluded the PCI Express slot was damaged as well. However, they also tried an older model video card that uses the PCI slots, and everything worked. So I ordered a new video PCI video card. It's on its way (Amazon). However, in the meantime I had a 1997-vintage video card sitting around, so when I got the computer back, I tried it. No signal to the monitor, not even motherboard booting beeps. Nothing. I called the shop back. He said even though my old card fit the PCI slot, new changes might have made it incompatible (16 vs. 32 bit, etc.). Anyway, even when I take the card out and boot, no beeps. That makes me wonder whether the old card did something, and now the motherboard is damaged beyond use. The man at the shop said the possible incompatibility of the old card should not have damaged the motherboard. Instead, he suggested that once a part of the motherboard is damaged (and we know the PCI Express slot is damaged), the motherboard as a whole can start acting erratically. However, it was beeping at the shop; now it is not.
I'm hoping those on this forum more knowledgeable about hardware than I am can give me some advice on the following questions.
(1) Does everything the shop did and said sound reasonable and likely?
(2) When my new PCI video card arrives from Amazon, if the computer still will not boot or even beep, does this prove I need a new motherboard?
(3) Is there any chance the motherboard could damage the new video card?
(4) Biggest issue: If I need a new motherboard, should I try to find one that accepts the same CPU and memory sticks? So far, I haven't been able to find one online. Or should I bite the bullet and get a new CPU and memory to match the new motherboard?
(5) If I get a new motherboard, new CPU, and new memory, can you suggest some possibilities of what I should look for? I don't want low-end, but for the work I do, I don't need really high-end, state-of-the-art either. I don't play computer games.
I have a problem when trying mounting, checking my ext3 partition. Is a external HD with my "portable" Linux system. Suddenly started to fail, when I try to boot it, the GRUB can't locate the config file, and show me the command line. I boot from my internal HD and try to mount it and have this messages.
Code: sd 2:0:0:0: [sdb] Attached SCSI disk sd 2:0:0:0: Attached scsi generic sg2 type 0 sd 2:0:0:0: [sdb] Unhandled sense code sd 2:0:0:0: [sdb] Result: hostbyte=DID_OK driverbyte=DRIVER_SENSE,SUGGEST_OK sd 2:0:0:0: [sdb] Sense Key : Medium Error [current] sd 2:0:0:0: [sdb] Add.

[Code]...
1.- What exactly is in this first sectors (ext3 metadata?)
2.- Is there some way to fix this quickly, maybe with some "sectors relocation", Or re-create the first logical sectors.
3.- If not, who could i make a full backup (something like dd copy), of all the partition.
4.- How fix it?, even with a long prosses, i don't know, maybe backup the file structure (with forensic tools) and copy into a new (and re-located) partition. This is my last option because the forensic tools sometime can't recover all files and sometimes only parts, or very old files.
I am running CentOS with single hard-disk (no RAID). I frequently saw people lost data because of hard-disk damage or failure.I am wondering if there is a software for monitoring the hard-disk so that we would know in advance and do the backup because thing goes wrong.
i don't understand this, why do you have to mount a usb or cd to use them? its such a hassle, in windows the usb/cd just works, but in linux you have to mount it, why? when ever i shutdown in linux, i am using ubuntu it says my drive didn't unmount on shutdown and it might damage my files?
I'm in trouble when I use the command yum, so I can not install anything on my CentOS 5.5 It's the following error: http://mirror.centos.org/centos/5/os...ata/repomd.xml Error importing repomd.xml for base: Damage repomd.xml file Trying other mirror Error: Can not retrieve repository metadata (repomd.xml) for repository based Already removed the most basic repository did not work. I have done some more changes still did not work
I've had a look at some similar threads but as I'm very new to linux they're already a bit technical for me. Sorry, this calls for someone with patience. I gather from other threads that disconnecting an external drive without unmounting is a no-no, and this seems to be the likely cause. Now the disk is read only and I'm unable to change any settings through the usual control panel on ubuntu. I'm just not familiar with the terminal instructions. I tried to cut and past a few command lines from other threads but I got some warnings that proceding could damage data. Like this one: WARNING! Running e2fsck on a mounted filesystem may cause SEVERE filesystem damage.
I am very new to linux, and I have a question regarding the filesystem check (fsck). The power recently went out and when I tried to restart linux the following error appears:
*/dev/sda1 contains file system w/errors, check forced it then goes on to say..
*An error occured during the file system check. Dropping you to a shell; the system will reboot when you leave the shell. Give root password for maintenance (or type Control-D to continue) I wasn't sure what to do, but checked some other online forums and they suggested running fsck manually - so I typed in the root password - and used the command, "fsck -A -V ; echo == $? ==" it then gave the following message
*WARNING!!! Running e2fsck on a mounted filesystem may cause SEVERE filesystem damage *Would you like to continue (y/n)
Again, I wasn't sure what to do so i just checked no. I then manually turned off the computer and was prompted at the beginning to press Alt-3. I was brought to another screen and it informed me one of the drives was degraded and suggested rebuilding the array. I tried doing this, but it still brings me back to the original error of, "/dev/sda1 contains file system w/errors, check forced," and the process continues.
Also, when I tried to rebuild the array, I didn't backup any of the data on our home directory before doing this (which was probably a big mistake). After being prompted to type the root password, I was able to give the ls command and look at all the directories...the home directory where our data was stored was empty and I am afraid I may have lost some information. Is there a possibility that data was lost when I was trying to rebuild using the old drives?
