Topic: Check disk - error while checking partition Gparted
I was using boot repair while running Ubuntu 16 GNOME LIVE version.
As prompted to close all programs so that it can perform File System Repair, I closed all programs but it didn't work. I manually unmounted partitions from GParted, then also it would get mounted again.
I checked disk and sda2 gave error. sda2 was created with bios_grub flag of size 10 MB and unformatted. However, strangely, it automatically shows format as ext4.
The following is the Checkdisk output:
GParted 0.25.0 --enable-libparted-dmraid --enable-online-resize

Force rewrite? yes
Superblock has an invalid journal (inode 8).
* ext3 journal has been deleted - filesystem is now ext2 only *
Superblock has_journal flag is clear, but a journal is present.
The filesystem size (according to the superblock) is 120942336 blocks
The physical size of the device is 2560 blocks
Either the superblock or the partition table is likely to be corrupt!

I removed and recreated the partition again but it is getting changed from unformatted to ext4. Please suggest how to repair file system and install GNOME.
