GRand Unified Bootloader) GRUB is the main boot loader used by Linux systems that allows you to implement multibooting.It is also known as GNU GRUB, it loads boot images and recognizes file systems. You can also see or alter partition settings, re-map the disk order on temporarily basis and perform similar tasks. GRUB errors mainly indicate that your hard drive is suffering from errors. To get your data back in such conditions, use your recent data backup. If backup fails, is incomplete or is not available, you require to use data recovery Linux applications that are commercial tools to recover lost data.
As a practical conditions, 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 see the stored data.
You might face this GRUB error message, if one of the given below 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 basic 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 resolve the above error, you should follow the given below steps:
• If fstab is pointing to incorrect partition, you require 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 continues, reformat the partition and restore lost data from backup. However, if you observe any of 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
