This is my fstab file after my experiment with it.

proc                                       /proc            proc  nodev,noexec,nosuid                                          0  0

Now my partitions mount as read only. There is some problem with sdb1 also, every time i have to press S to boot. Please help me to edit fstab to its default state.

You can just place a # in front of the line /dev/sdb1 /media/sdb1 vfat users,user 0 0 to comment it out or remove the line.. – precise Mar 8 '14 at 5:52
The mount manual page says: If the msdos filesystem detects an inconsistency, it reports an error and sets the file system read-only. The filesystem can be made writable again by remounting it. So, you can open a terminal and unmount the partition with: sudo umount /dev/sdb1 and then remount those defined in fstab with sudo mount -a – precise Mar 10 '14 at 17:40

For remounting the root file-system with read/write access use:

sudo mount -o remount,rw /
