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 LinuxTo solve the existing bhavior, consid er 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 partitionChroot into you system to determine the available kernel imagesIf kernel image is missing, copy it from disc to boot partitionEnsure 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 residesBooting 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 backupIf 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. This Data Recovery Linux application provides advanced features including Disk Imaging, RAW File Recovery, File Filer etc. The application is compatible with most of the Linux distributions, like Red Hat, SlackWare, Turbo Linux, Sorcerer, SUSE and others.
