Fixing “the symbol 'grub_env_find'...” Error Message

A system boot error message is a nightmare for any computer user. In most cases, the user is unable to bypass the error message, resulting in inaccessibility of information/data saved in the hard drive. A Linux based system too becomes unbootable after such error messages. Few main causes for the occurrence of boot error message on a Linux based system are improper system shutdown,  incompatible upgrade of Kernel, boot loader corruption or improper upgradation, and virus attack. This error message can be easily surmounted if the user has maintained an updated backup. It allows him/her to restore the data and continue with his/her personal or professional work. But in case, a backup is not maintained or backup falls short of restoring data, then the user has no option, but to use an advanced Linux Recovery software.

As a practical case, below error message pops up when you attempt to boot your Linux based system:

“GRUB loading.
Welcome to GRUB!
error: the symbol 'grub_env_find' not found.
Entering rescue mode...
grub rescue>
Please consider upgrading the severity of this bug to critical.”
All the data saved in the hard drive becomes inaccessible after the above error message pops up. Additionally, the same error message pops up every time the user boots the computer.

Cause:

The root cause liable for the occurrence of the above error message is improper upgradation or corruption of GRUB boot loader.

Resolution:

To resolve the above error message and to access the hard drive data, you will need to follow the below steps:

Install another GRUB from another system to boot your system.
If that doesn't helps, format the hard drive.

Formatting is one of the most common measures followed by most of the computer users to overcome any boot error message. The process installs a new file system on your hard drive and deletes all the entries of the previous file system, resulting in inaccessibility of all the hard drive data.

While most of the users think that the data after formatting is permanently lost, the fact is that it can be easily recovered by using an advanced Linux Recovery tool. Such Linux Data Recovery software easily recover all kinds of files from a formatted Linux based hard drive.

 Linux Data Recovery  is an effective Linux Data Recovery tool that recovers formatted data from Ext4, Ext3, Ext2, FAT file system based volumes. The tool supports almost all Linux distributions, like Ubuntu, SUSE, SlackWare, Mandrake, Gentoo, etc. The read only tool is available as demo and complete version.
