To access the multiple features and functions of two different operating systems, a user installs two or more operating systems on different partitions of the storage media. The user can boot any one particular operating system at the starting of the computer system. However, the booting process in the dual boot computer system can be halted due to file system damage, metadata structure corruption, malicious software like virus and more. Once the booting process is stopped, it shows an error message that results in making the volume unmountable and data saved in the hard drive inaccessible. In such situations, the user needs to recover and restore the data from the latest backup. But, if you have not created any backup, then you need to use advanced Linux Recovery application to recover and restore the inaccessible data. As a practical scenario, the user installs two different operating systems (Windows XP and Ubuntu) on its personal computer. When the user attempts to boo t Windows XP, it sarts normally. However, the user encounters the below error message when he tries to boot Ubuntu:Error 17: Cannot mount selected partition - This error is returned if the partition requested exists, but the file system type cannot be recognized by GRUB.After the above error message appears, the data saved in the hard drive partition (where Ubuntu is installed) becomes inaccessible.

You can also try a grub CLI direct kernel boot. The user can boot to the LiveCD and open a terminal sudo fsck /dev/sdbX substitute you ubuntu partit ion for sdbXBut if the user receives the same error message even after following all the above measures, then he needs to reinstall Ubuntu in that particular partition. Reinstallation process will delete all the previously stored data in that partition. To recover the lost data, the user needs to use effective Linux Recovery software.
