Fedora is an operating system that is built on top of Linux kernel. It is a RPM (RPM Package Manager) based operating system and is available in different variants, starting from Fedora Core 1 to Fedora 11. On occasion, you observe partition issues while installing or upgrading Fedora and the installation fails with an error message. It is likely that to resolve the issue, you need to repartition the hard drive, which causes data loss as a result. Hence, to restore lost information, use your recent data backup or alternatively, scan your hard drive using Linux Recovery applications (If backup is invalid or doesnât exist).
As a practical instance, you try to install Fedora and receive the following error message: âError: Error informing the kernel about modifications to partition /dev/
– Device or resource busy. This means Linux won’t know about any changes you made to /dev/
until you reboot – so you shouldn’t mount it or use it in any way before rebooting.â Where, âpartition nameâ is the name of partition on which you are installing Fedora. The setup crashes and the installation process hangs, after this error message. Cause The above error might arise due to incompatibilities issues of Fedora core with partitioning scheme. Solution To correct this issue, you need to follow these steps in order: ⢠First, you should use Linux System Rescue Disk to repartition your hard disk ⢠You can then reboot your system with Fedora installation CD and reformat the hard disk partitions. You can also reformat using Linux System Rescue Disk ⢠Install Fedora and restore lost data from backup ⢠If backup is damaged, not updated, or non-existent, Linux Recovery applications can be used for complete data recovery purpose. Linux Recovery software are commercial tools to recover lost data from logically crashed Linux based drives. Such software employ powerful algorithms and have data conversant techniques to safely restore missing information. They come equipped with advanced features like, automated recovery options, graphically rich interface, and complete recovery abilities in all cases of data loss. Stellar Phoenix Linux Data Recovery is a comprehensive tool to recover lost data from Ext2, Ext3, and ReiserFS partitions. It provides robust Data Recovery Linux features like, RAW File Recovery, File Filter, and Disk Imaging etc. The application is compatible with most of Linux distributions including Fedora, Red Hat, Mandrake, SlackWare, Turbo Linux, Gentoo, SUSE etc.

For Linux file systems, Superblock plays a vital role. It defines the file system itself. Linux uses this metadata structure to hold its file system information like file system type, size, mount status and also metadata information about other file system structures. If superblock is found to be corrupt, file system canât be mounted. This causes data loss and hence needs Linux Data Recovery as the solution. Superblock defines file system type and if it is corrupt, it may fail to give to this information with an error similar to: âSuperblock does not describe correct file systemâ The error also describes that system is unable to read the superblock. Also, if device contains the file system, then its superblock is corrupt and fsck is required with an alternate superblock. By alternative superblock , it refers to its duplicate copies on disk. Linux maintains duplicate copies of Superblock to avoid Linux Recovery requirements. These are located at different disk locations. The primary superblock lies at location 0 and group descriptors 1-6. However backup copies can be located using the following command: # dumpe2fs /dev/sda2 | grep superblock It will display the backup locations of superblock. Using these locations of superblock, file system can be attempted to mount. However if the process fails because of corrupt superblock backups, we need to refresh the file system by formatting the drive. It will create new copies of all file system structures. Lost data can be later restored using backup. However if no valid backup exists, Linux Data Recovery applications can help recovering. Linux Recovery software are the applications to recover lost data using specific scanning algorithms. These applications can carry out recovery in all cases like superblock corruption, inode table damage, group descriptors faults and others. These software offer graphically rich user interface and hence can be used easily. These products are safe for data as are designed as read-only. They offer quality features that assist users in recovery. But the software are not recommended to be installed on same drive to prevent overwriting. Stellar Phoenix Linux Data Recovery is the powerful and safe application to recover data from ext2, ext3 and reiserFS file system based disks. This software supports most of the Linux distributions like Red Hat, SUSE, SlackWare, Turbo Linux, Gentoo, Fedora and others. The application is safe for Ext3 Recovery and can be easily used through its graphical interface, which is rich of features.

Superblock is the most significant component of a Linux volume that restrains critical information about files and folders in file systems as ext2, ext3 and more. It enables us to mount and access the file systems. Superblock corruption primarily occurs due to metadata structure damage, file system corruption, unexpected system shutdown, malicious software like virus and more. In most cases of superblock corruption, the volume becomes unmountable and the data becomes inaccessible. In such situations, you can restore the lost data using an updated backup. However, if you have not maintained any backup or it is not up-to-date, then you need to recover your data by using advanced Linux Data Recovery tools. Consider a practical scenario, when you attempt to boot your Linux system, you encounter the below error message: âWrong fs type, bad option, bad superblock on /dev/hda8, missing codepage or helper program, or other error. In some cases useful info is found in syslog – try dmesg | tail or soâ After running dmesg tail, you encounter the below error message: âCouldn’t mount because of unsupported optional features (2000200)â After the above error message appears, the system becomes unmountable and data stored on the hard drive volume becomes inaccessible. Additionally, you encounter the same error message each time you attempt to boot your system. Cause: The main reason behind occurrence of the above error message is superblock corruption. Resolution: To resolve the problem and access all inaccessible data, you need to follow these steps: 1. Boot your system by using an alternate block by running the below command: e2fsck -b 98304 /dev/hdb8 2. Once the file system gets restored to the point at which it can be mounted, you need to fix it by using this command: e2fsck -c /dev/hda8 -c parameter checks for the bad blocks However, if the above steps are not able to resolve the issue, you should consider reinstalling Linux. A clean Linux reinstall will erase all existing data from the selected volume. For complete recovery of lost data, you should use efficient Linux Data Recovery software. Such Linux Recovery tools incorporate effective scanning algorithms to recover all your lost data. These recovery tools provide highly graphical user interface that makes them easily understandable without prior technical knowledge. These tools recover data post situations like superblock corruption, group descriptor faults, inode table damage and more. Stellar Phoenix Linux Data Recovery is the foremost Linux Recovery tool. It supports recovery from Ext2, Ext3 and ReiserFS file system based Linux volumes. This Data Recovery Linux tool gets installed on Windows (Vista, XP, 2003 and 2000) and the affected Linux drive is connected as slave.
Boot loaders such as GRUB (Grand Unified Bootloader), LILO (Linux Loader) etc. enable you to select to boot a particular operating system in multiboot or dual boot systems. After selecting the operating system (for example Linux), the booting process initially starts with the booting of Linux Kernel program. A Linux Kernel program is the central component of a computer operating system. It requires the corresponding drivers to access the device on which the file system is based. To avoid any conflict due to all imaginable drivers in the kernel, it uses initial ramdisk (intrd). The intrd is the temporary file system, which is mostly used for preparations before the real root file system can be mounted. Problems might occur when intrd gets loaded before Linux Kernel program. In such situations, the hard drive volume becomes un-mountable and the data saved in the hard drive becomes inaccessible. In such situations, you need to recover your data from the latest backup. In case, no backup is available or the backup is corrupted, you need to use efficient Linux Data Recovery applications to recover your lost data files.
Consider a practical example, when you attempt to boot Linux operating system, you encounter the below error message:
âMust load Linux kernel before initrdâ
The above error message occurs each time you try to boot the Linux operating system on your computer. After the above error message appears, the data saved in the Linux volume becomes inaccessible.
Cause:
The above error message mainly occurs when the intrd gets loaded before the Linux Kernel program.
Resolution:
To resolve the above error and access the data, you need to remove the intrd from your computer. However, if you still encounter an error, then only option left is to access the volume by reinstalling the Linux operating system. A clean reinstall of the operating system will erase all previously stored data in the hard drive. In such scenarios, you need to recover lost data by using effective Linux Data Recovery software. These advanced recovery applications incorporate high-end scanning methods to recover lost data from a logically corrupted hard drive.

Sometimes when you try to install device drivers on your Linux system, you might fail to do it. It could be due to incompatibility of the operating system Kernel with your device driver or device. To work around this issue, you need to install the latest version of Linux kernel. It may include âforcedethâ patch, which is capable of resolving most of the incompatibility issues. In some cases, after installing the latest version of Kernel, when you reboot the Linux system, you might face the following error message:âfsck.ext2: No such file or directory while trying to open /dev/hda8. The super block could not be read or does not describe a correct ext2 file system. If the device is valid and it really contains an ext2 file system (and not swap or ufs or something else) then the super block is corrupt, and you might try running e2fsck with an alternate super block: e2fsck -b 8193 fsck failed.âAfter this error message, neither the system boots nor any file can be accessed.Grounds of the issueAs stated in the error message, this problem generally occurs due to super block corruption or file system corruption. è Super block and file system are two most important data structure of Linux system. Proper functioning of both these is required for ensuring effective working of the system. After corruption, the operating system could not locate the file and thus can not retrieve it. ResolutionTo work around this problem, you need to install a fresh copy of super block and file system. It is possible through formatting of the hard drive and reinstallation of operating system. Though, it will remove the errors but will also erase all the data stored on your hard drive. It is the worst scenario of data loss and needs Linux data recovery to get it fixed. Linux data recovery is feasible with the application of third party Linux recovery software known as Linux data recovery software. Linux recovery software is easy to use and thus allow you to have simple and fast data recovery Linux. Stellar Phoenix Linux Data Recovery is the most advanced Linux recovery software offered by the data recovery giant- Stellar.

Linux is a popular open source operating system, which offers great security features. You can install Linux operating system on a system that is already using Windows operating system, by making it dual-boot. The dual-boot configuration allows you to use features of both operating system. The boot loader enables you to select any of these operating system to boot from. However, in some situations, this behavior may cause damage to the Linux volume. This behavior leads to critical data loss and you need to use Linux Data Recovery to get your precious data back. In a dual-boot system, you can access data from your Linux hard drive, even if you have used Windows operating system to boot the computer. To access data, you need to mount the Linux volume. But in some situations, when you attempt to access the Linux volume by mounting it, the process can not complete and you encounter any of the below error messages:âcan’t find ext2 File System on dev ide1 (22, 65)âOr âmount: wrong file system type, bad option, bad superblock, or too many mounted file systemsâWhen these errors occur, you can not access data from the Linux hard drive partitions. If you try to boot the system using Linux operating system, it stops responding with some boot errors. It causes data loss and need Data Recovery Linux to get your valuable data back. CauseThe issue occurs due to corrupted or missing Ext2 file system of your Linux volume. The file system or Linux hard drive volume may get damaged due to numerous reasons such as virus infection, power surges, improper system shutdown, operating system malfunction, and improper mounting of the hard drive. ResolutionYou can sort out this problem by restoring lost data from the most recent backup. Backup is the most excellent solution to prevent data loss situations. However, if you do not have backup or its not updated, Linux Recovery is required to handle the situation. The recovery is best possible with the help of third-party Ext2 Recovery applications. The tools use powerful scanning algorithms for in-depth scanning of the hard drive and extracting lost data from it. You can easily recover lost data using these programs even if you do not have prior technical skills as they have simple graphical user interface. Stellar Phoenix Linux Data Recovery is a read-only and advanced application to recover all types of lost data. The software recovers data from Ext4, Ext3, Ext2, FAT32, and FAT16 file system volumes. It is compatible with all popular distributions of Linux including Red Hat, SUSE, Fedora, Debian, and Mandriva.

When you start a Linux system, BIOS first select the boot device and load the boot sector. Further, it looks to load the kernel image, after which the setup code runs to execute the Kernel. If your system is prompting that it can’t find the kernel image, the system will fail to boot. One of the probable reasons for this behavior is boot partition corruption. It leads to data inaccessibility and to restore data completely, it is crucial that you have valid data backup. Thus you are always recommended to maintain and update a good backup copy of your important data. In any case if backup fails to restore, you should use Linux Data Recovery applications. You might encounter the below error message with your Linux-based system: “GRUB Error 15: File not found” This error is specific to GRUB (GRand Unified Bootloader) installed Linux system and occurs in two different GRUB configurations: • Installing GRUB • Booting the system and starting Linux To solve the existing behavior, consider these methods: Installing GRUB • The error refers that system cannot find a file, generally kernel image file. Kernel image file should exist on boot partition. Follow these steps to remedy it: Boot the system from Linux installation disc Mount the root partition Chroot into you system to determine the available kernel images If kernel image is missing, copy it from disc to boot partition Ensure that kernel name should match with that in grub.conf file and kernel line in this file refers to the correct partition • Make sure that BIOS is properly configured to detect the disk on which kernel resides Booting the system and starting Linux • Ensure that you are using correct setup and root lines • Try to upgrade GRUB • Use GRUB-install script • If these measures fail, check the boot partition for errors using fsck. It might be corrupt. • If fsck fails to correct, reformat the partition and reinstall. Restore lost data from backup If due to any reason you find it unfeasible to restore from backup, you need to use Data Recovery Linux applications. These are powerful Linux Recovery software built to locate and restore lost data from Linux-based drives. Stellar Phoenix Linux Data Recovery is a non-destructive tool to locate and recover lost data for Ext2, Ext3, and ReiserFS file systems.
