General :: Ubuntu Won't Boot And Boot Repair Fails?
May 8, 2011
I downloaded ubuntu 10.10 iso, made CD, installed as dual-boot with win Vista home premium and used it for a week to access the 'net and email. Yesterday, while deleting an email, the "d" key stuck down while I was issuing <CTRL>D and the cursor froze. I then rebooted by using the reset button and saw many lines of text including "kernel panic". so I reset and booted into 'repair boot'. Again, many lines of text which stop at the same place if I try this twice.
I assume I've fried my ubuntu install and would like to fix or re-install it. When I installed it, I let the [wubi?] installer make decisions except choice of drive because it picked the external, USB drive. It appears to've used about 80 G on internal drive D: I could boot from the distro CD and see if it will re-install but I'm concerned that I may not fix my problem or that it may mess up my windows installation.
I have hard disk contain Windows 7 and Ubuntu 11 so I cloned it to new one but when I replaced it no OS working just dell mark appearing then restart by itself. In the past started up by Ubuntu menu to select Windows or Ubuntu so now how can I fix Ubuntu boot to avoid reinstall everything.
I have XP, Win7 Pro and F 11 installed. Before I installed F 11, Win 7 boot mgr was working fine. I then installed F 11 and I went to System/Admin/bootloader to edit it and it wouldn't bring up the boot loader. In the attachment was the error msg. Now my only option when I boot up is F 11.
I do not have access to the Win 7 DVD only the F 11 install disk since I am on a fishing trip and need to use Win 7. How can I repair to the grub boot loader to boot into Win 7?
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.
as friend i am new in linux i install open suse and window 7 in dual boot .. every thing was fine but last week i got terrible virus attack at my win7 so i format as fat32 using yast partionerbut now i also delete first boot partion .. now i can't install window on it .. there is blue screen problem stuck the installation
I have a win7/10.10 dual-boot set up, more or less following the lifehacker.com tutorial (I know, I know). I had to reinstall windows, and its taken over the MBR so that only win7 boots now. My shared drive and the ubuntu filesystem are still there, I just can't get to them without a boot cd. So, I tried to follow the tutorials, which all basically say to reinstall grub or grub2. I tried one method, but ubuntu told me that installing grub2 anywhere but the MBR was a bad idea
I am building a 10.04.1LTS server. I am putting the /root filesystem into a Software RAID1 partition. I want to keeo my /boot partition outside of RAID.Is there a way to have a boot partition on both sda and sdb so if one drive fails the second boot partition will work away - or should this be kept in with RAID also.
I was upgrading our lab's dhcp server to Lucid and it totally died. I have it running on a Debian recovery cd right now. I ran into a bug in gtk which I seem to have fixed, but now I have more serious errors. If I boot without a CD, I get dumped into a busybox shell after the machine fails to boot. From the live CD, I tried dist-upgrading again and it dies trying to build and install rsyslog with a broken pipe error. I am at a loss as to what to do from here short of reinstalling (which is the last option as this server has a lot of custom configs on it)
My Internet connection works fine when I boot Ubuntu with the CD and it does not work when I boot from the Hard Drive. It was working then it stopped. I tried to diagnose the problem but I am not familiar with Linux.
I opened a Terminal window and entered ipconfig (don't laugh ... sadly, i've been in Windows for too long) ipconfig was something that could not be found in my terminal window so i exited.
Next it was System->Administration->Network Tools. I ping'd www.yahoo.com and it said it could not find it. hmmmm. Let's see if restarting the system will fix it.
I did a shutdown and when it came back up; same problem. Ok, i really didn't think it would magically correct itself; this is Linux after all. Windows? Well sometimes you can fix things by turning them off and on. Next, another shutdown and I rebooted with the CD instead of the Hard drive and here I sit entering this help question in.
I am guessing that a file or setting got changed in /etc/someplace and I am not even sure of that. Can anyone point me in the correct direction? I am assuming that there is a setting which is correct in the CD version that is not not correct in the HD version and somehow i need to find what it is and synchronize it with the CD version.
I installed Ubuntu to use ddrescue to clone my dying drive and keep the log.Now the question is:Does Ubuntu really try to repair a corrupt NTFS disk during boot?If so, how can I change this behaviour, including any disks attached to the system in future?I had a similar question for the live cd, I think it should be easier now, as we can configure the system.Btw am I the only one to think an 'auto repair' by default is no good without asking for permission? It's something I dislike on Windows. A corrupt structure is likely a hardware problem, and in this case a repair can terribly damage the file system.
I need to boot in WXP just because the guys at the company don't want to update for Linux drivers in the TS so I can't connect from home unless I do it in Windows XP. But today WXP refuses to boot, when the progress bar appears, the system boots automatically. The WXP CD doesn't help, the repair console doesn't let me run chkdsk or anything (dir C: gives an error about listing addresses or something like that). Is there any way to use fsck or anything in Linux to repair the WXP NTFS partition?
My old computer started randomly rebooting so I went out yesterday and bought a new one. It's a standard Intel 64 architecture with 2gb ram etc.The old computer was running Lenny however I'm happy to upgrade, so I just went to the main Debian download site and downloaded:debian-6.0.1a-ia64.netinst.iso (this didn't work, apparently ia64 is for itanium and my machine is definitely not that), so I downloaded: debian-6.0.1a-amd64-netinst.iso, burnt the CD and ran the install. First time through I had a power failure.
Second time through (a complete fresh start - new partition and everything) it went all the way through to completion and reboot.Clicked 'Continue' to reboot and the machine reset as it would normally and the Grub loader started okay, prompted for the "Debian amd64" standard boot image, selected that and the first 6 lines appeared normal, then the messages wizzed by so fast that only superman could read them. Then they stop - here is some of the content...
[3.816673] Kernel panic - not syncing: Attempted to killl init! Call trace: get_empty_filp panic
[code].....
Running it again I get similar stack stuff but it's a different place: [3.541816], [3.427502] And sometimes if I wait for a minute or two it will continue on further but appear to crash again. Hardware details (everything is onboard - no added cards):
I just now re-installed 10.04 on my box, but now I can't get back into Windows. I'm getting the BOOTMGR not found error, that I'm familiar with, but the circumstances surrounding it are completely new to me. In the past I've encountered errors from hard-shutdowns where I couldn't mount the partition, until I checked it with windows first, but I can't boot into windows at all any more. I'm pretty sure my grub is pointing to the right location:
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?
I'm using Ubuntu Lucid and any sudden power loss will usually cause problems with the file system. When I bring the computer back up, Ubuntu will then scan for errors at boot-time and if any errors are found it prompts me to select whether to repair or ignore them. I would much rather have it select the repair option automatically so that I don't have to be physically present.The reason for this is that i have a web server that should come back online automatically after a power loss.
I downloaded Ubuntu desktop 10.10 on to my Acer 5741 laptop (which I checked online for comptability), following the site's instructions to the letter. I used the USB installer to create a live USB which seemed to go fine. I then restarted as instructed and changed the USB to be selected to boot. However, from that point, the OS fails to load. I get several pages of code loading, then a screen with a logo at the bottom, then my screen just goes dark.
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 was using the disk utility on Ubuntu 10.04 and wanted to make by 500GB external NTFS formatted USB drive into 1 x 50GB FAT32 and 1 x 450GB NTFS. I clicked the option that said format or create a partition and it basically wiped the whole thing in a split second leaving me with 500GB of seemingly empty space. Obviously the files are still there but I cannot boot the drive to view anything. I have downloaded testdisk, but don't know how to use it, but I am sure there is a relatively simple solution here. I am currently repairing the boot sector of the drive as Test Disk showed the drive as "no type" i.e. not FAT/NTFS/ext4 etc., but shows the correct amount of used space though, but I cannot view anything err go, I cannot use the undelete command as yet.
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 then only created /dev/md0 which consist of /dev/sda2 & /dev/sdb2 in RAID 1 mirror.
When I boot the system, I show that Swap fails during boot in bright 'red' letters. I don't know if it failed activating both or just any swap partitions in general. When I look at 'df -h' while my system is booted, I show:
I am inexperienced in using Linux, and just installed Ubuntu 10.10 on an external hard drive. I didn't want to mess around with re-partitioning my hard drive, which has Windows 7. I figured that I could just run Ubuntu from the external, and if it gave me any problems with Windows, which I unfortunately need for work, I could just unplug it and boot normally. However, GRUB appears to have installed some component to the local hard drive. Whenever I try to boot from the local hard drive, I get this error message: "error: no such device: 8b84f351-7770-4908-b12f-0cbd31bc3662 grub rescue> " Another thing is that in the boot menu, only the CD/DVD drive and local hard drive are options, it won't even register the external. Any suggestions on what may have caused this error? I saw from other posts that GRUB doesn't like multi-drive systems. Also, would it be possible to delete GRUB from my system, then allowing Window's MBR to take over?
I have a bad entry in /etc/fstab I have tried to tried to change in boot but it says read only. It will not take su. I have a livecd but I can't seem to get to my filesystem from a terminal where I can specify su
I initially had a dual boot where I could decide to either boot into Windows 7 or Ubuntu 10.04. It work seamlessly. At some point, however, when I booted into Windows, it just seem to only load it "half" in the sense that the desktop just turned black (but when ctrl-alt-del was hit I did receive a screen with the different options).
I suspected there was a problem with grub and proceeded to restore the Windows bootloader by booting into the Windows CD and repairing the computer by entering the commands:
After restarting I suddenly do not have the option to boot into Ubuntu (where did it go?) and booting automatically into Windows the original problem persists.
Any idea what happened here and how I can restore things?
I just installed SuSE 11.2 on top of where 11.1 used to be on my hard drive. Acronis Operating System Manager will let me boot into XP Pro but it tells me it cannot find SuSE in the master boot record. If I repair the master boot record in SuSE, XP Pro disappears. What do I do?
I'm very new to Linux and recently setup a desktop PC with Puppy 5.2.5. only. I chose to have a permanent install on the hard drive and loaded additional PETS and utilities as I thought needed for my use. Last night after immediately booting up the PC I had a power cut lasting a few minutes. When power returned and I repowered the PC, I found during Puppy's boot sequence it reported an error and remained in what appeared to be a console mode - did not carry through and load my desktop. So I inserted the Puppy CD and booted from that but I'm afraid I'm not familiar enough with Linux to understand how I can get back my original desktop setup and run once again from my hard drive without having to go back to scratch.
I am travelling so would really appreciate a few tips that should hopefully get my pc running again. (I have internet access via a kiosk, and can burn a disk if necessary, but the smaller the download the better)I have a few ideas that with some help I should be able to fix the partition.1. Is there a simple way to use use grub, to mount all partitions read only and not to fsck them so I can logon in normal user and sudo and hopefully fix the parition?or 2. Download a small version of ubuntu or something that I can burn to CD (my machine cannot boot from usb) so that I can repair the machine.3. Download the ubuntu installer (alternative) and try and reinstall the necesary usr partition?
both root and home partition have suddenly become corrupt, and the repair tool from the installation disk just loops (Do you want to repair? Yes! Do you want to repair? Yes! Do you...).
