My laptop suddenly one day stopped working. (I wasn't able to write anything onto the disk). When I restarted it, it booted up into a emergency boot mode. After I ran fdisk -l, it says, Partition 3 (one containing the os), does not start at physical sector boundary.

Partition 3 does not start on physical sector boundary.
Partition table entries are not in disk order.
How can I fix this?
Here is the complete fdisk -l result
