General :: Accidentally Wrote Over The Wrong Partition?

Mar 17, 2011

When doing an install of Linux Mint, I accidentally installed on a partition that already had data on it, so now that partition has a clean install of Mint instead of the data that was there before.I was hoping that I could at least recover some of the data from this partition, so my questions would be what, if anything, could I recover, and how would I go about doing that?

Ubuntu :: Accidentally Clicked Wrong Session Blank Screen?

Oct 27, 2010

Posted this in the wrong section so I'm reposting it, is that ok? I installed lxde and logged out and switched to it, but my internet wasn't working (but that's a different thread after I fix this, I was going to try installing wicd) So I tried to go back to gnome, I misclicked and accidentally started a different session. I think it said openbox/gnome, all I get is a blank screen with just the desktop background. It's set to automatically log me in, so when I restart my computer it goes back to the blank screen. How do I get back to the login screen?

General :: Accidentally Replaced The Partition Table Using GParted In UBUNTU

May 20, 2010

This machine has UBUNTU & wINDOWS XP. I'm currently logged into UBUNTU. I was just checking the features of GParted and accidentally clicked Device > Create Partition Table. A default MS-DOS partition table is created. Now if I re-start the Gparted there is nothing. Its showing entire disk as UNALLOCATED space.

Lucky thing is All the drives (C:, D:, E:) are currently mounted and I'm in UBUNTU. I guess its possible to re-create the partition table using current status. how to do this. This is a lab computer. If its not recoverable. I'm completely screwed!

General :: Install OpenBSD 4.6 On My PC And Accidentally Overwrote My Boot Partition ?

Jan 15, 2010

I was gonna install OpenBSD 4.6 on my PC and I accidentally overwrote my boot partition.

Initially my partition table looked something like this:

Quote:

This doesn't look like a partition table

Probably you selected the wrong device.

Partition 4 does not end on cylinder boundary.

Partition table entries are not in disk order

That's what my partition table looks like according to fdisk. So I'm wondering how I'd go about recovering /dev/sda3 (what /dev/sda3 was before I blew it up).

Oct 23, 2010

i used to have ubuntu 9.i decided to move to sabayon so i used the live cd to install it ,resize the ubuntu partition and use the remaining space for sabayon.while the resizing procedure i got an error(i dont have a copy of the error log file but i know it has something to do with an anaconda process).i aborted the installation and the result was an filesystem that couldnt be mounted.when i try to mount the hdd i get this:

Code: Error mounting: mount: wrong fs type, bad option, bad superblock on /dev/sdb1,
missing codepage or helper program, or other error
In some cases useful info is found in syslog - try
dmesg | tail or so and this is what i get from fsck: Code: $ sudo fsck -f /dev/sdb1

Ubuntu :: Accidentally Created Partition Table On Primary HDD

Mar 9, 2010

Alright, so, I booted using linux live, and was poking around Gparted, and was going to test some things on my extra hdd (80gb, IDE) -I thought that extra hard drive was selected, what I clicked Create Partition Table. Apparently, it was my primary hdd, (250gb Sata, Windows Vista x64) that was selected. I think I may have tried to cancel it after a few seconds, realizing what was happening, but yeah, it now shows the entire hdd as unallocated space. I immediately shut down the computer, pulled out linux live and tried to boot to windows, but I immediately got an error saying the disk couldn't boot, asking for a system disk.

There was a thread with a guy who had a similar thing happen to him, but the thread dropped off... [URL]
sudo ./testdisk_static
Opened testdisk for me, but now that testdisk is open, I'm not really sure what I need to do. I'm guessing that the boot sector on that hdd is gone. Are my files gone forever? There are some files that I don't have backed up on there, that I'm hoping are not gone. I would love it even more if I could somehow just repair that boot sector, and not have to reinstall everything on my machine.

Ubuntu Installation :: Accidentally Formatted /home Partition - Recovery?

Feb 11, 2011

I was installing 10.10 x64 today. I wanted to manually partition the disks, since I have a /home partition from a 9.10 installation which I want to keep.Unfortunately, I selected to convert the ext3 /home partition to ext4 and didn't realise it was formatting the partition until it had just begun. In desperation, I pulled the power plug, but now I can't access the partition (using the LiveCD) - comes with an input/output error.What are some strategies to recover the data on the partly formatted partition? I don't think much, if any, was actually formatted.

Ubuntu :: Accidentally Deleted Partition - Now Stuck At Grub Rescue

May 26, 2011

Deleted the Ubuntu partition by accident. Now at a loss as how to get Windows working again. I had all my files saved, and did a full format and reinstall to Windows. Thinking that it would just overwrite grub but this thing is like a virus.. I cant do **** at the grub rescure command prompt... it just sits there with a cursor... Even stuff like reboot and quit or exit don't even work... what the hell? So I pop my Win7 install cd in and I find that for some reason I have no recovery console... just the option to install. I install but no grub, the little virus is still there and I just wasted an hour of my life while Win7 installed again because I still cant view it.

I deleted all the partitions and wiped the entire disc and grub is still there.. I was thinking that Windows would just replace grub automatically. Heh the Bootsector always seems to get owned on Windows and I expected grub to be just as useless but in it's own way, it's worse.

Ubuntu Installation :: Accidentally Deleted Partition Table On Lvm Physical Volume.

Jul 18, 2010

I was trying to remove the physical volume from an old drive. So I opened gparted and told it to rewrite the partition table. The only problem is I targeted the wrong volume, I wiped the partition table on my 4tb raid5 array This 4tb array has everything! All my movies, tv shows, music. The only things I have backup up off site are my smaller files like documents. I was about to lose my whole media collection.

I did some research and found a solution that I will post here in the hopes that someone will google "I deleted the partition table on my lvm" and be find the solution.You should find in your filesystem a /etc/lvm/backup folder. LVM puts a copy of the crucial lvm information there every time you change the the volume group.

In this folder you will find a file for each volume group. In this file you will find the uuid for all of the physical volumes that make up that group.The first step is to recreate each physical volume with their original uuids. In my case I had only 1 physical volume, which was my raid5 array. My recreation command looked like this:

pvcreate --uuid cLrY02-zrVi-D0Vi-cIPB-6fF5-ed0c-XFF0os /dev/md0

Now I have a physical volume with the same uuid it had before. It is essential that you correctly match up the uuids with the correct physical deviecs.The recreated pv is empty, the volume group needs to be recovered. This is done by using a special tool and the backup file. For me the command looked like this:

vgcfgrestore --file /etc/lvm/backup/raid5 raid5

This tells it to recreate the volume group using the information in the backup file. The backup files looks for the uuid of the PV, which now matches the correct volume. The coordinates in the backup file match up to the data on the array an suddenly everything is back!

When I deleted my LVM partition table I did not damage any of the actual volumes on the volume group, I just wiped out the table of contents. The backup file had the information needed to rewrite this table of contents.

Fedora :: MAYDAY Accidentally Messed Up Fedora Core 12 Partition - Error Reading The Disk

Jan 18, 2010

I did a horrible mistake due to lapse in my concentration. Here is the 80 GB IDE disk geometry:

=> C: Windows XP SP2 15 GB partition
=> D: NTFS parition - 10 GB
=> E:F:G:H: NTFS partitions on the Windows Extended partition.
=> On the same Extended partition, there exists Linux /swap and /root partitions.

What happened was:

a) I wanted to delete the H: parition which was residing adjacent to Linux partition
b) By mistake I opened the Explorer and clicked the Mouse on H: partition and left it like that (forgot)
c) I opened Add/Remove program list but did nothing, to do few uninstalls after partition deletion.
d) Now I opened compmgmt.msc for Disk Management then deleted the H: partition!

Then XP reacted strangely and got almost hung

e) Then I switched OFF and ON the PC.
f) Most shocking was GRUB screen vanished (crash console appears) which means that Linux partition got deleted instead of H: partition!!

It's important to share with you that Fedora Core 12 possess the default BOOT flag. I thought that it's nothing big deal, only a case of Boot flag toggle with DOS bootable CD but am shell shocked to find after hitting the fdisk from DOS it says Error reading the disk!!! I felt like collapsed for a while, don't know how I did such a mistake. how to boot into my Windows XP. I can't afford to loose data or bear the expense on Data recovery

Debian :: Grub 2 Autoconfiguring For The Wrong Partition

Does anyone know where grub 2 gets the default partition from or does it just select sda1 automatically?

Ubuntu :: GParted Deleted Wrong HDD Partition

Mar 17, 2011

Most times I use my brain but some how I really screwed up with deleting the wrong hdd's partition which was an 500GB NTFS with all of my custom programs, art, web design & so on which can not be replaced. Is there a way to reverse this process? Keep in mind I am not Linux friendly being I do not know the commands & so on so any copy paste commands with good detail on what it does would be greatly appreciated!

I used GParted to delete & already hit the accept but no other changes have been made on the HDD after that. I am currently running in Live mode as I was going to install on the 80GB which is the one I meant to delete but instead had a nice moment of insanity & deleted the 500 instead!

Ubuntu :: Disk Space Is Wrong On Root Partition?

Jan 15, 2010

My root partition seems to be full bur is wrong because I have a partition with 15Gb space and the data is arround 7.5Gb I have:

Quote:

~$

PHP Code:

sudo df -lha
S.ficheros            Tama�o Usado  Disp Uso% Montado en
/dev/sda5              15G   14G  660M  96% /
proc                     0     0     0   -  /proc
/sys                     0     0     0   -  /sys

[code]....

When I look for specific info about what is taking the space using du command I get that the space used by the root system is 7.2Gb. I get to the same conclusion when checking the space with Nautilus.
