I have a dual boot laptop with windows 10 and Ubuntu 18.04. Ubuntu was installed and working fine, untill suddenly it stopped booting up
It gets an Input/Output error while reading /dev/sda6.
On the other hand, the windows boot normally and I can even access data on my linux partition /dev/sda6 using a third party program DiskInternals.
I have tried reinstalling linux with an Ubuntu 18.04 live USB but it fails with the error message "error fsyncing/closing /dev/sda input/output error"
Any help is appreciated.

The superblock could not be read or does not describe a valid ext2/ext3/ext4
filesystem. If the device is valid and it really contains an ext2/ext3/ext4
filesystem (and not swap or ufs or something else), then the superblock
is corrupt, and you might try running e2fsck with an alternate superblock:
e2fsck -b 8193 <device>
or
e2fsck -b 32768 <device>
