GRUB (GRand Unified Bootloader) is the standard boot loader used by Linux systems that allows you to implement multibooting. Also known as GNU GRUB, it loads boot images and recognizes file systems. You can also view or alter partition settings, re-map the disk order on temporarily basis and perform similar tasks. GRUB errors generally indicate that your hard drive is suffering from errors. To completely restore lost information in such situations, use your recent data backup. If backup fails, is incomplete or is not available, you need to use Linux Data Recovery applications that are commercial tools to recover lost data.
As a practical instance, when you try to boot your Linux-based system, it gives the following error message:
“GRUB Error 17 : Cannot mount selected partition – This error is returned if the partition requested exists, but the filesystem type cannot be recognized by GRUB”
After this error message, you can’t access the stored data.
You might encounter this GRUB error message, if one of the following conditions is true:
• The mount point for boot in /etc/fstab file is pointing to an incorrect device. fstab is the file that lists all available disks and their partitions and conveys their initialization information when mount command is used.
• Your Linux partition is suffering from file system corruption errors. GRUB fails to recognize and start corrupted partition.
To remedy the above error, you should follow these steps:
• If fstab is pointing to incorrect partition, you need to edit it for boot device. It is the plain text file that can be edited if you log in as a root or use sudo command to become root.
• Try running fsck on your boot partition to fix file system errors. If problem persists, reformat the partition and restore lost data from backup. However, if you observe any issues with backup, Linux Recovery applications can be used for complete and safe recovery process. Such Linux Recovery software extract lost data using powerful scanning algorithms. Besides, these applications empower you with advanced recovery functionalities and ease of deployment.
