Ubuntu :: Repairing Installation Without Losing Data?
Feb 9, 2011
I have Ubuntu 10.10 installed on my computer (no other OS) and it wont boot up. I don't want to lose the files in my documents. I tried accessing them using a live CD and then copying them from the harddrive (home folder then 'richard' then documents then tried to open the folder but I dont have permission to and there seems to be no way of changing this.
The files are definitely on my harddrive but I dont seem to have a way of accessing them!
Is there anyway of either accessing them and copying them to a usb etc or repairing my installation of ubuntu without erasing the files in my documents? Opening in recovery mode etc wont work.

I would like to move a samba fileserver from ClearOS5 to Ubuntu. It has raid1 (software) and I would like to save one partition from it, md3. The other partitions could be used for Ubuntu. How would I go about this so that I don't erase data from md3 and is it even possible?

I 've some problems with my current version 11 that probably has been fixed in the last version (14). I've updated other non-critical systems through the yum services but from 13 to 14. I've a productive workstation working on ver.11. Is there any possibility to update through yum or other methods through without risks of losses data information?... It's really complicated to backing up Mysql databases, web services and other hundreds things installed. I know, it's convenient carry out a backup but is it a higher risk to dump from 11 to 14 trying to keeping the information inside?

Right now I have a 320GB system drive and 3TB data drive. I want to add two more 3TB drives and do a software RAID5 3x3TB. Is that possible without losing the data that is already on the data drive?Just want to make sure before I bought the 2 two drives. Not looking for instructions on how to do it,but if you want to include some that would be great too Just making sure it will work.

I have a 160gb hard drive with no partitions. Ubuntu runs on the entire disc. I want to cut off 60gb from my file system as a storage drive without losing the data that i already have on it.
I don't want to reinstall Ubuntu and cannot afford to lose all my data. Is it possible to do so, without having to reinstall the OS.
I downloaded Gparted, whats next?

I am facing a severe problem on many Desktop PC's, whenever an employee is working in Gnome-Open-Office.org document (i.e. Wordprocessor, SpreadSheet, or any other Gnome-office application) and due to power outage after restarting, the previously open document either does not open or it shows a recovery dialogue after clicking on recovery button or clicking on cancel in either case document contain nothing (empty). The file size of the document is either 0kb or within few Kbs range.
Any one have any idea about it ? what to do ?? or any other alternative which is already tested in such environment (i.e. electricity failure )? or any options to be turned on/changed?

I need to reinstall OpenSUSE 11.4 with KDE Desktop on my HP Pavilion Desktop and I was wondering if it is possible to do so without losing my data, and no backups? I can't back up my data for reasons I'm not going to go into so I need to know if I'll lose my files...there isn't anything truly important...just stuff that'd be mildly irritating to lose...

I have a software RAID array using mdraid that consists of two 1.5TB drives that I use for storage, the array is mounted at /Storage. I am running out of space in the array so I ordered two more 1.5TB drives to create a 4 drive RAID 1+0 array which will be 3TB big. My question is how do I create the new array and not lose any data?
The drives and partitions are sdc1, sdd1, and soon to be sde1, sdf1. I currently have 4 RAID arrays (md0,md1,md2,md3). I think I can create the RAID 1+0 array with the two new drives, copy the data from my current array to the new one, remove the old array, then add the two original drives to the new array. But I wanted to ask on here first to make sure my data doesn't go poof.

I would like to resize my /home ( /dev/sdb6 ) partition - without losing data - to make room to create a swap partition (at the moment, I don't have any swap. Is it dangerous ?) IIRC, it was possible to change partition sizes from the install disk in repair mode (?) But I cannot find that repair mode on the 11.3 install disk. Has it been removed or is it somewhere deeper in the install or update process ?

to start: I am a 100% linux virgin. I have yet to boot once. I have a 1TB external HD bought today (), which I formatted to 32GB Fat32 and the rest NTFS. (The 32GB partition is the second in order) I tried installing 11.4 with the full release DVD, and managed to get through the 'partition' part of the setup without raging about losing valuable internal HD data. I changed / to the 32GB partition, and figured a native format was safer: formatted it in setup as Ext4, and installed after ignoring the under 128GB warning (the machine is only a few months old).
The installation seemed to go well. The loadup was unsuccessful. There were plenty of "fails". I was given a command screen with "Login:" and after, "Password:". It seemed to take the Login, however the correct password echoed back a "Login module failed" or something similar. Interestingly, an incorrect password yielded a "Incorrect Login". What I may need to do (?):
1. I did not specify a /home or swap during install
2. ?
3. ?
etc

I have a 300 external usb drive which I have got when using windows and so is using a fat32 filesystem. I have since moved to linux only and am mounting the drive as vfat however I think I may as well convert it to ext4 if possible for (amongst others) performance and security reasons. The problem is I don't have a separate drive which would hold the 250gb of data temporarily whilst I changed the filesystem of the drive so I am hoping there is a way to format as ext4 whilst retaining the files?I know partition magic on windows allowed you to change between filesystems whilst keeping the data but does anything similar (and free! ) exist for linux?

Can any data be lost on ext4 with full journalling mode when electricity crashes? I know it's possible on filesystems like JFS and XFS because they don't journal data (only metadata). When ext4 in "journal" mode journalles both - data and metadata. Does it give 100% guarantee that no data can ever be lost in case of problems with electricity?

I updated to Thunderbird 3 by following instructions from http:[url]....Everything updated nicely, but in menu I don't have Thunderbird anymore - there is Shredder instead.Also Firefox was automatically updated - with change of name to Shiretoko with different icon. Wanted to make sure I added safe repositories, and why these changes?
ps. i checked some websites and seems like it is installing alpha/beta versions. so since it is not working now - how do i revert to previous versions without losing data, and how do i install thunderbird 3.0 then.

I have Windows 7 working on my laptop. I have 20GB space unpartitioned. I want to install a flavor of Linux like Fedora or Ubuntu in that space, but I have heard that keeping a dual OS configuration sometimes results in losing data stored on the hard disk. I've also heard that it may sometimes cause unrecoverable problem because when Linux is loaded on hard disk it will take over the boot loader from Windows.
Is this correct? Moreover, I have 6 partitions in Windows, but if I use a Live CD for Ubuntu or Fedora to boot, then it is not showing some partitions -- sometimes it shows only 4 or 5 partitions. What might be the problem, and how to resolve it without formatting the whole hard disk and repartitioning it?

Just ran into an uncomfortable problem. I usually never save any documents on my machine, and keep all my stuff on an external USB hard disk. (an 80GB TrekStor DS microdisk q.u)
Well yesterday this disk just would not mount.
Read through related posts but nothing seemed to work. Even tried it on a Windows machine.
Tried TestDisk utility. Found nothing wrong with the drive, but still could not repair the MBR.log code...
Palimpsest Utility recognized the drive, but just will not let me do anything with it except format it.
How can i repair the partitions and MBR without losing all my data?

repairing the MBR on my raid array. I have three disks, each with three paritions:root (sda1 sdb1 sdc1) 59GB swap (sda2 sdb2 sdc2) 1.12GB grub/boot (sda3 sdb3 sdc3) 298MB I have been able to get this running and it has been working fine for several months. A few days ago, I installed 10.04 to a USB stick but did not disable the hard drives at that point and so the MBR was overwritten. If I leave the USB stick in, it boots fine from that stick. However now I can't get the boot from the raid array to work correctly. I can do the following:Load 10.04 from the Live CD install mdadm recreate the root partition using
Code:
mdadm --assemble /dev/md0 /dev/sda1 /dev/sdb1 /dev/sdc1
I can mount and view the files on md0 with no problems. It's not corrupted in any way. When I installed, I followed the directions to make each of the grub drives bootable. However I don't know for sure whether grub was installed on each partition separately or if it was installed on the assembled partition only. I have tried using
Code:
sudo grub-install /dev/sda3
and got warnings, something to the effect
Code:
Cannot find a device for /boot/grub
no path or device specified
Auto-detection of a filesystem module failed
specify the module with option '--module' explicitly
I have also been able to get to the grub rescue prompt but my keyboard (wireless USB) is not recognized and so I can't type anything in at that point.

We have a Fedora11 installation that we Ghosted (Norton Ghost) to a bigger Hard Disk because the old one was failing
I know there is an extra step for linux where you fix fstab because it points to all the wrong locations, could someone walk me through this or link me to somewhere that can walk me through it?
Do I need to do this editing from a Fedora 11 Live CD (as its gone missing) or will a Fedora 13 CD do the trick?

I am facing some issues with my openSUSE 11.2 installtion. Yesterday i installed win 7 so the grub is now wiped out. I have also taken mbr backup in USB. I tried following things to make things work.[/HTML]
1) Repair using openSUSE DVD booted using DVD then automatic repair but it couldn't find any root partition. After showing error that no root partition found it crashes to a blue screen with advanced configurations from there i was able to use shell but cant see and mount any linux partitions. i tried mounting the root partition it gave the error :"please load module ext4dev before mounting" how can i install grub without losing my present installations.
2) Tried booting with Ubuntu & kubuntu 8.04 live cd .. both gave a error and refused to boot. then tried openSolaris which failed to detect the USB drive so couldnt restore the GRUB to /dev/hda.
