Geom Error in Linux

When you boot your Linux system, GRUB (GRand Unified Bootloader) proceeds in few stages. Your system boots successfully if all these phases complete without any errors. But sometimes, you observe that Linux system halts and an error message is printed at stage 1. In such situations, 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 Data Recovery applications can be used as recovery solutions.

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

"Geom error"

Boot process halts and you can't access the data.

Geom is the modular storage framework that provides 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 supported 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

Solution

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 issues 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.
