had a bad experience when Fedora 15 overwrote the ext4 partition of a data disk to MVL during the installation process.I cloned the HD and now I am working on it. However, my first attempt resulted in 900.00 number-renamed files into the lost+found folder. And that's not what I want: with this number of files I need to recover the directory structure and the files real names.I know this is a hard issue for being discussed in the forum and that I shall look for some expert help, but, I wished to useis bad moment as an opportunity of learning.
I was messing around with the windows 7 install and wiped a valuable partition on a drive, I ripped the sata cable out afterwards... is there a way to reconstruct the table?
I erased my partition table. Can anyone recommend a good method of reconstructing it? And if this is impossible, can anyone recommend a good method of data recovery? I had an ntfs partition with windows 7 and a larger ext3 partition that ran Debian.
I'm running Test-disk on the SystemRescueCD at the moment (cross your fingers).
Is there a difference between using GPT partition table when formating hard drives and MS-DOS partition table? What are the advantages/disadvantages of using either?
I had 40 gb of unused space at the beginning of my drive, then a 15gb primary ext3 partition for /, then a 100GB ext4 primary partition for /home, then a 4 gb extended partition that contains two 2 gb swap partitions.
I installed FreeBSD on the empty space at the beginning of the drive. The slice I created did not start on the first block. There were a few MB of free space before and after it.
After the installation finished (with no errors), grub would hang on the "Grub loading/Welcome to Grub screen". I booted a squeeze CD in rescue mode and reinstalled grub to /dev/sda. After rebooting, Grub still hangs at the same place.
I booted a live CD and checked the output of fdisk. For each of my partitions, it says "Partition does not end on cylinder boundary". I am hoping that whatever happened to my disk is not recoverable. Fortunately, I backed up some essential files beforehand, but I still don't really want to lose my old squeeze system.
I have an unallocated space at the end of my hdd, which is about 10 gb. I installed Pardus on that space, but then deleted the partition to install something else (I know I did not have to delete it, I could simply install the new thing over it), i dont remember exactly how, but it was from my Debian System, not from a LiveCD.Now, I am unable to use that space. GParted gives an error and says:Warning: the kernel failed to re-read the partition tableon /dev/sda (Device or resource nusy). As a result, it may not reflect all of your changes until after reboot.
I have just installed the newest Debian Stable 7.8 release on my new notebook. Before installation I had to free some disk space from the preinstalled Windows7 with ntfsresize and fdisk. In addition to the existing three primary partitions I created an extended one with three logical partitions for /(root) /home and swap, see the output of 'fdisk -lu'
For some reason I put a bootable flag on sda7, and the only small concern during installation was that some BIOS systems might not work with boot-flag no logical drives. Now, every time I boot I get this "Invalid partition table!' message which I must 'enter" away before I get to the GRUB menu.
i have got an Debian Lenny NAS with 7x1,5TB of a Softwareraid5. Kernel Version is 2.6.32. The Raid ist mountet in /media/raid5. The System ist on a seperate disk and work fine. After i tested the performance of the raid with:
Since i had done this i cant find any Data on /media/raid5. cat /proc/mdstat and mdadm --detail /dev/md0 looks fine. All UUID's are good. But: The SuperBlock is unreadable and the partition table was not found. mke2fs -n /dev/md0 shows some Backup of the Superblock , but i cant repair it with fsck.ext4: Illegal inode number on /dev/md0.
Do i have any chances to restore my windows partition table after tried to install debian and i used the entire disk instead of the free space i had alocated for this
after i figured out what i did i stoped the installation but was to late ... i answered yes at write partition table changes on disk question
i tried win7 automate recovery tool from dvd and manual install of mbr with no successful result
I'm trying to define the partition table type (I want to set it to msdos) for an automatic installation using preseeding file. (Why? I want to setup a software RAID 1 with two 2TB disks, by default the installer uses gpt partition tabless on those disks, where it's tricky to install grub(2), as there is no mbr, and the root partition is on a md device) During manual installtion it is possible to set the partition table type (by setting debconf priority to low).
[Code]...
Does anyone know what I have to put in my config file so that a msdos partition table will be created Also any other solution is welcome. I just want to have my root partition on a raid 1 and have grub installed, so that it boots up (No other OS is installed on the boxes. Debian squeeze is used)
I believe this has something to do with an mdadm update which was included in the release. When I configured the array, I didn't partition the disk devices, so maybe that has something to do with it. I am thinking of rebuilding the array and partitioning prior to build, but a quick fix would be referable.
And also something appears to have happened to the raid device since the update.
Prior to update, the array was /dev/md0 - now it is /dev/md/0 which is a symbolic link back to /dev/md0.
mdadm --detail --scan now reports /dev/md/0 where previously it reported /dev/md0
I created a new RAID1 array on a fresh system and immediately after the create, these messages appear at 5 minute intervals.
I would like to build an oem style install partions that is bootable with menu to choose if I want to run install or boot already installed system. I would like to include current source packages on the same dive so if I don't have internet access at time of install, can can still install what I need.I know with Windows Vista and Windows 7, you can get this but how can I do this with Debian?
I was installing opensuse 11.2 in parallel with windows xp.but during installation suddenly power has gone and after that opensuse is giving me the error message corrupt partition.i am also not able to login in xp. so I decide to reinstall windows, I got the error saying "invalid partition table" after the first restart of windows xp installation.
I tried to use windows system recovery console and committing fixmbr and fixboot commands, but didn't work. i have 2 window partition(1 for windows and 1 for data).i do,nt want to format 2,nd partition.
How can I installed windows?My plan was first to install windows xp, then opensuse again.
I have tried to automate the configuration of a usb drive with not much success.
The problem that I have is that I have a large amount of usb drives that have a partition table of type "loop" and I need to change them to "msdos". The size of the drives vary and I need to use FAT32 or FAT16 file system.
I've tried various partitioning commands and gui applications but cant find one that I can give a one line command to to set the partition table, maximum partition size and file system.
I was reading another thread about someone with a bad partition table and I decided to join this forum. I'm not going to take any drastic actions with the partition (/dev/sda3) in question. I am going to wait for instructions on what to do first. I am not very good with Linux and need some hand holding. System: DELL 4550 Dual-Booted with XP and Ubuntu. Works OK, just no swap. Well, here's what I did: I deleted a partition for Windows XP Pro because it was a trial, and it ran out. I then decided to slide the swap partition for the Ubuntu Linux that I dual-boot into over. (If this was successful, I was going to try expanding the root partition to take up the unused space.) I used Gparted on a CD to do this, as I figured it was safe to do.
I now cannot mount the swap space at bootup (and have to go into a backup version of the OS), although I can use Gparted in Linux to execute the "swapon" command, and it appears that it worked because I now see "swapoff" as an option on the context menu. (I actually don't even need a swap partition, except to hibernate.) If I highlight the swap partition and click on "Drive" on Gparted's menu bar and select "Create Partition Table", it will erase all data on /dev/sda, so how do I fix the bad partition table non-destructively?
Everything is installed and setup on my system, but when I setup my partitions I chose my Windows partition to be bootable. Can I just use cfdisk to toggle the bootable flag so my linux partition is bootable and rewrite the partition table?
I want to change my sda2 partition to ntfs type. i have installed GParted but it is returning a strange type of error. Here is the error dump file...
[Code]...
WARNING: the kernel failed to re-read the partition table on /dev/sda (Device or resource busy). As a result, it may not reflect all of your changes until after reboot. WARNING: the kernel failed to re-read the partition table on /dev/sda (Device or resource busy). As a result, it may not reflect all of your changes until after reboot.
Is there a program that will reread the partition table and update the kernel even if one of the unmodified partitions is mounted? I installed my system on one partition, then I added another with free space. Now I want to format the second partition, but the kernel doesn't know about it yet. I tried sfdisk -R /dev/sda, but it refuses while the root partition is mounted. Is there anyway I can avoid rebooting?
USB flash disk partition disappeared as well as partition table I'm not sure about the cause
Code:
root@u# less /var/log/syslog usb 5-1: New USB device found, idVendor=058f, idProduct=1234 usb 5-1: New USB device strings: Mfr=1, Product=2, SerialNumber=0
[code]....
Where did the partition table go? The device had one ext3 partition something around 4GB(size of USB storage device). I need to restore few files from this device.
I'm trying to clone a Linux install to a different laptop. It's made a little complicated by two facts:
1) The 'new' laptop I'm trying to copy my Linux installation to is actually older and has a smaller hard drive then the computer I'm copying from
2) The computer I'm copying from has both a windows and Linux installation; I only care about the Linux partition.
I figured I would copy only the Linux partition from my primary computer to the laptop, sense the laptop doesn't have a large enough hard drive to copy everything. So I used the DD commands to copy SDA3 (main Linux partition) from my main computer to SDA2 of my laptop. When I came back a few hours later I was surprise to find my laptop trying to reboot itself (I never turned it off). It would keep starting to reboot, failing, and restarting itself. Not too surprising sense its boot partition wasn't changed so it's trying to boot into centos when I copied a redhat partition to it.
The problem is that when I used a redhat boot disk the rescue mode was unable to find a Linux partition to mount. /dev/sda2 exists, but trying to mount it gets the complaint "No such file or directory". "fdisk -l" lists sda1 (the boot sector) and sda2. Sda2 is the correct size and reports Linux LVM for its system. But "fdisk -l /dev/sda2" gives the error message "Disk /dev/sda2 doesn't contain a valid partition table" Did I not clone the drive correctly, or was an error caused due to the boot sector not being copied yet (the laptops boot sector is smaller then my old computers, so I can't copy from old computer to laptop)? Can I salvage the laptops partition table somehow, or do I have to repeat the cloning process? And if I do have to re-clone my computer can anyone tell me what I did wrong the first time so it works this time? I don't care if I copy just the Linux partition or both windows and Linux. Even though my main computer has a larger hard drive I'm only using about half of its available space so it should be possible to copy both partitions if I could ignore the unused sections of the harddrive.
Edit: I used DD to copy a tiny part of the Linux partition from my laptop so I could look at it. Most of it is illegible binary of course, but I scrolled through till I found some text right near the beginning:
Code:
VolGroup00 { id="F2MWxh-....-BidcLe" seqno = 1
[code]....
So it seems that the DD command did copy everything over to the laptop, which is good to know. I noticed that it says device="/dev/sda3" right in the middle of the code I just posted. The Linux section of my original computer was SDA3 but I copied it to partition SDA2 of my laptop. So is the problem because the boot partition is for the wrong device? I don't suppose if I modified that one line to say SDA2 it would be able to load correctly? (Not that I know how I would modify the line, short of using the DD command again).
Two days ago I repartitioned my laptop HD and added the latest Ubuntu (2.6.35-25-generic) to the existing Vista and existing Ubuntu (2.6.32-28-generic via upgrades from 9.14(?)). Prior to this install it was using Grub with menu.lst from the old/upgrade Ubuntu. After the install the boot menu labels the partition with Vista as the Windows Recovery partition and the recovery partition item is no longer present.
At first I wondered how I could get Vista to boot. I found that SuperGrub cd would boot it OK. Then, it dawned on me that the boot menu item was not the recovery partition, but instead the Vista OS partition mislabelled . Vista loads just fine from it. The recovery partition is no longer listed as it was with Grub/menu.lst. SuperGrub will not boot the recovery partition, showing an error "missing BOOTMGR".
I tried installing Ubuntu 10.04 LTS on my girlfriend's lenovo using a live disc. First we tried it out to show her the wireless would work fine (her previous lenovo was not ubuntu friendly at all). She's interested in keeping her windows 7 partition along with the lenovo recovery partition, so I tried doing a dual boot install. I manually moved the cursors setting the disk space on each partition, and we allowed Ubuntu to do the rest. Much to my dismay, the installation failed.
I've done some reading over the internet, and I think in our case it would be best to use a Wubi installation. We're interested in using 10.04, so where can we find a wubi installer of Ubuntu 10.04?
Also, any ideas why the installation might have failed? The iso was downloaded off the ubuntu main site, and we burned it using infrarecorder.
What I believe has happened is that I've corrupted the partition table. Essentially one of my partitions' ending point exceeds the maximum number of cylinders/sectors on my drive.
Essentially I have the same problem as on the thread @ [url] but do not know how to fix this and am afraid to reformat/partition based on sectors without really knowing what I'm doing here.

When I try to look at SDA in GParted everything shows up as unallocated (though it's obviously not) and it says
In my efforts to resize my BTRFS Partition, I accidentally unmarked my BTRFS partition as being BTRFS, and can't mark it back as I can't find the numeric ID for BTRFS and how to apply.
is it possible to use a Windows-based recovery partition on a dual-boot computer to overwrite the Ubuntu partition and remove the GRUB loader? For instance, if you booted up your computer, accessed the hidden recovery partition and used it to reset the computer to it's factory default settings, would that effectively remove the Ubuntu partition and the GRUB loader? Would a completely new installation of Windows overwrite/uninstall Ubuntu and GRUB automatically?
My set up is a dual boot between windows 7 and ubuntu 10.04. This laptop used to have vista on it. See image below for my partition set up. pretty obvious where ubuntu should be.I accidentally selected the wrong entry in grub and booted into an acer windows recovery partition. despite exiting as soon as it loaded, the long story short is that it has goodbyed linux.On booting i now just get a grub rescue prompt.I have eventually managed to boot into a liveUSB (cd drive is botched too )As you can see from the screenpic, testdisk shows linux is still there but there are quite a few entries from the upgrades.So, if i can restore the partition around this linux partition will grub come back with it and will all be merry?
I havent mounted any volumes on the drive yet, but i think i need to back up my data before messing with the partition table. is it cool to mount them to pull some data off?general advice for how to proceed would be great.Im not too hung up on keeping the linux install itself. whats gunna be easier? install into that 16gb space and then re add windows to grub, or try and recover this partition?
I installed Ubuntu as shown in the wiki and when I went to restart it gave me a lovely blinking cursor and nothing else. So I held down option, loaded into osx, reinstalled rEFIt and got my menu on startup. Unfortunately, the partition sync tool doesn't seam to be working, it gives me an error: Status: MBR partition table is invalid, partitions overlap. Error: Not Found returned from gptsync.efi
I originally had an Ubuntu partition on my hard drive which occupied about half of it. I installed Windows 7 in the remaining unallocated space and I was planning on doing a grub update from a live cd afterwards. BUT when I looked at my partition table, the space where the ubuntu partition used to be is now unallocated space!
I need to copy partition table for sda, I have 3 primary partitions and 1 extended partition on sda. I understand that fdisk cant copy extended partition table and I need to use sfdisk.
Correct me if I am wrong -
1. For primary partitions
Code: dd if=sda-mbr.bin of=/dev/sdX bs=1 count=64 skip=446 seek=446 2. For extended partition Code: sfdisk -d /dev/sda2 > backup-sdX.sf Where it will store the files after backing them up. I tried SUSE 11.2 DVD, it has back up partition table utility under repairs-advanced options but it suggests saving partition table to floppy. Why it doesnt offer to save it on a removable medium or to CD.
I got swap space full error and the ubuntu version of "blue screen of death". I used Disk Utilities to delete a 2.1GB unused partition. When I tried to create a swap space partition (with Disk Utilities) it failed. In the mean time ubuntu did some security updates. When I tried to create again Disk Uilities did not complain but only created a small ~ 500 kB partition. I deleted that and reboot and got "unknown filesystem grub rescue>". I booted from a USB key successfully. Now Disk Utilities and File Browser can see all the partitions and files on the hard drive, but GParted thinks the entire hard drive is unallocated. I vaguely remember that there are two partition table on the hard drive. It may be that one of them was deleted (when I removed the ~ 500 kB partition with Disk Utilities earlier maybe?). It seems at least the other partition table is still intact since Disk Utilities and File Browser can still see all the partitions and files. Is it possible to restore the deleted or damaged partition table and make the hard drive bootable again?
