I want to use ubuntu 16.04 with windows 8.1 (dual boot) . But after installing ubuntu it only boots with a USB. after booting in the grub page it shows 4 options . they are :-
try ubuntu without installing.
install ubuntu
odx installation (for manufacturers)
check for drive errors.
I am now using the 1st option because after installing ubuntu this is the option that I find suitable for using.
I have installed ubuntu 2 times but nothing is working out for me.
then I saw a post which instructed me to write some codes in the terminals.
the result I got after I tried the below codes:-
$ ls -l /dev/disk/by-label/
total 0
lrwxrwxrwx 1 root root 10 Apr 27 15:46 RECOVERY -> ../../sda5
lrwxrwxrwx 1 root root 10 Apr 27 15:46 UBUNTU\x2016_0 -> ../../sdb1
lrwxrwxrwx 1 root root 10 Apr 27 15:46 Windows -> ../../sda4
lrwxrwxrwx 1 root root 10 Apr 27 15:46 WINRE -> ../../sda1
$ sudo grub-install /dev/sdb
Installing for i386-pc platform.
grub-install: error: failed to get canonical path of `aufs'.
Even I am not able to access any files in my pc through Ubuntu. it shows the error :-
unable to access "windows".
Error mounting /dev/sda4 at /media/ubuntu/Windows: Command-line `mount -t "ntfs" -o "uhelper=udisks2,nodev,nosuid,uid=999,gid=999" "/dev/sda4" "/media/ubuntu/Windows"' exited with non-zero exit status 1:

I am not able to understand what is wrong and I am not able to find a solution for it. I am a new to Ubuntu so do give a bit of explanations.
