´Grub loading stage 1.5….´ Linux Error and Recovery

GRUB (GRand Unified Bootloader) is the standard boot loader used in Linux systems. When you turn on a Linux based computer, the system uses MBR (Master Boot Record) to load initial bootstrap program. This MBR contains GRUB stage 1, which further loads GRUB stage 1.5 or stage 2 directly. GRUB stage 1.5 is located in 30 KB of hard disk after MBR. GRUB stage 1.5 loads stage 2, which presents a boot menu to select the required operating system.

But sometimes, the system gets stuck at GRUB stage 1.5 and doesn´t boot anymore. In such critical situations, you can´t access your stored data and need to use your recent data backup to restore lost information. But when data backup seems to be damaged, not updated, or is totally absent, you require using Linux Data Recovery applications that could restore the information intact.

Consider a practical example, you try to boot your Linux-based system and boot process hangs, displaying the below error message on screen:

"grub loading stage1.5"

GRUB stage 2 doesn´t start and hence, you can´t select from the boot menu.

Cause

Possible causes of the above issue are:

• Your hard disk is not properly configured in BIOS

• GRUB installation problems

• File system and/or operating system issues.

Solution

To resolve the above behavior, you should try these methods:

• Make sure that your hard disk is set to autodetect in BIOS configuration

• Try reinstalling GRUB. To do so, you need to boot the system using bootable diskette

• Run fsck to check and repair file system corruption. If problem continues, you need to reformat the hard disk and reinstall. To restore lost data, you should your recent data backup. But if backup is giving errors or is not complete to give required data, use Linux Recovery applications.

Linux Data Recovery software are advanced tools that use powerful scanning algorithms to scan the affected media and restore lost information. Equipped with features like, automated recovery, read-only design, and complete documentation, these read-only tools serve as the most valid tools to recover lost data.
