Descriptor Table Corruption and LILO errors

LILO or LInux LOader is the standard boot loader used for Linux systems. Instead of the file system type, it can used in boot sector of partition or MBR. When you start the system and LILO loads, it performs a lot of steps and displays the word ‘LILO’. With each letter you see on the screen, it indicates that it has successfully completed a task. but if LILO fails at some stage, you find that the complete word ‘LILO’ is not displayed and hence you can’t boot Linux and access your data. To restore the lost data, you require to use a recent data backup. However, if data backup is not available, invalid or not up-to-date, Linux data recovery solutions can be used to extract the lost or inaccessible data. Consider a situation, you start the Linux system and the boot process halts with three letters ‘LIL’ on the screen. After the happening of this issue, you can’t boot the Linux system.

The above issue occurs if descriptor table is corrupted or damaged. The space on a Linux based hard disk is divided into blocks, which are further organized into block groups. Each of these block groups is described by a group block descriptor. Descriptor table is the index table of these group block descriptors.

To resolve this issue, you require to carry out these methods: You should first need to verify that disk parameters in BIOS (Basic Input Output System) are correct. Try reformatting the partition and reinstalling LILO. You need to restore the lost data using an updated backup. But if you face some issues with the backup, you can use Linux recovery applications. If the problem persists, you should run fsck to check and correct any corruption issues. Reformat the hard drive if fsck fails to fix file system problems and restore data from backup. Linux data recovery software are robust applications that recover and restore lost data safely. Such software use powerful scanning algorithms to locate missing information. In addition, they provide interactive interface, automated recovery procedures and to-the-point documentation .
