Most of the Linux users, from system administrators to general desktop users, have used the tool called boot loader. It is a utility that loads operating system into main memory during the boot process. Different variations of boot loader tool provide different levels of functionality and support. It is the most important part of your Linux system and its proper working is important to have a smooth operational system. The most common example of Linux boot loader is LILO. LILO or Linux Loader comes as the standard boot loader on several Linux flavors. It does not depend upon any specific file system and could boot your system from hard drive or floppy disk. During boot process, you could select one of the 16 images for booting. You can set various parameters, like root device, independently for every kernel. LILO could be placed either in MBR (Master Boot Record) or in the boot sector of partition. At system startup, only BIOS drivers are there for LILO to access the hard drives. Due to this reason, in old BIOS, the accessible part is limited to 0-1023 cylinders of first two hard drives. In later BIOS, LILO could use 32-bit LBA (Logical Block Addressing) for accessing the whole storage for all hard drive that BIOS allows to access. Under some circumstances, you may encounter some sort of error messages, while booting your Linux system. The error messages may sound like the following:Internal ErrorAddress mark not foundSector not foundInvalid initializationBIOS errorThese error messages may occur due to missing or corrupted LILO. In such situations, all your data may becomes inaccessible and you fall in need of Linux Data Recovery.Linux Data Recovery is best possible using powerful Linux Recovery Software. These software systematically scan the whole hard drive, locate the lost data and them complete efficient Linux Recovery. Stellar Phoenix Linux Data Recovey software is a result oriented and fully automated Linux Recovery software that is capable of handling even the most severe data loss situations. It is compatible with most of the Linux flavours and supports Linux Data Recovery from Ext2, Ext3 and ReiserFS file system based Linux hard drives.
