Geom Error in Linux

When you boot your Linux system, GRUB (GRand Unified Bootloader) moves in few stages. Your system boots successfully if all these phases complete without any errors. But sometimes, you see that Linux system halts and an error message is printed at stage 1. In such conditions, you fail to access stored data and need to restore lost information from backup. However, if data backup is damaged, incomplete, or is not available, Linux recovery applications can be used as recovery solutions.

As a practical conditions, when you boot your Linux-based system, it gives the below error message at stage 1:

“Geom error”

Boot process stops and you can’t access the data.

Geom is the modular storage frame work that gives a standardized way in order to access storage layers. Its name represents impact on disk geometry.

Cause

Geom error occurs if the location of further stages is not present in the area that is expected by reading the disk with BIOS directly. Possible causes of this behavior are:

• LBA (Logical Block Addressing) is not activated or BIOS doesn’t have correct hard disk values

• The hard disk is not registered in BIOS

• You have changed hard disk geometry in BIOS

• You have moved hard disk or controller to another machine after installation

• BIOS is unable to detect complete hard disk capacity or can’t address cylinder of Linux boot partition

Resolution

You need to follow these methods to resolve the issue:

• Make sure that LBA is active in BIOS and all hard disk values are correct (these should match with that have been provided by manufacturer

• Check if hard disk is properly registered in BIOS

• Correct hard disk geometry configuration in BIOS

• You need to ensure that correct hard disk and controller are active

• If problem persists, reparation your hard disk and reinstall. This deletes all the data, so restore from backup.

If you find any problem with your data bakup, or if no backup is available, use Linux recovery tools. Such software provide complete Linux data recovery using safe, powerful and advanced scanning algorithms.
