Boot Failure in Linux-- cause and solution

In Linux and UNIX OS, daemon is the computer program that run in the background And not in direct control of the user. These daemons Are used to configure your hardware like devfsd and it performs task like scheduled run of cron in your Linux OS. But sometimes, these programs fail to start while booting the Linux system. It can occur due to inconsistencies or corruption issues in the file system. In such circumstances, you need to use most recent and valid data backup to restore the data. However, if the data backup fails then efficient Linux Data Recovery application are to be used to recover the lost files.

Consider a Situation, you try to boot Linux system and daemons fail to start. Additionally, when you reboot the system, you get error message and When you use the boot drive to mount your root partition, it fails.

Cause For the failure

As described above, if root partition’s file system suffers from corruption, the daemons may fail to start at boot up. It can occur if any of the structures like inode, super block, etc is damaged due to user errors like unexpected system shutdown, incorrect use of commands and more.

Solution

You can follow these steps to solve this issue:

• You can run the fsck command to diagnose and repair file system issues of hard drives root partition.

• you need to reformat the hard disk and restore the lost data from a recent data backup If you find errors that fsck can’t fix . A format operation erases all the data from the selected Linux partition. But, if you do not have a valid data backup, you need to scan your hard drive using data recovery Linux software to recover the lost or inaccessible files.

Linux Data Recovery application is specially designed to scan affected from logical data loss. These software can locate the missing information and then safely restore an recover it. You will find such Data Recovery Linux tools with user-friendly interface plus remarkably fine recovery capabilities.
