how to reset login password for linux 17 64 bit
 

I attempted the forun reset in linux community. #5. Use the arrow keys to highlight the lin that begins with kernel and press the e key.

there is no line that begins with "Kernel".

GNU GRUB version 2.02 beta2-9ubuntu1

setparams 'Linux Mint 17.1 Cinnamon 64-bit, 3.13.0-.7-generic /dev/sda1)'

gfxmode $linux_gfx_mode

insmod ext2
set root= 'hdO, msdod1'
if [ x$feature_platform_search_hint = xy ]; then

You;'re using GRUB2, which adds large amounts of complexity to the process, unfortunately. However, what you're trying to do is fairly straightforward. In your case, you need to edit the line beginning with "linux". This line contains the path to the kernel and the options to be passed to it. You'll want to append the word "single" to this line to boot into single user mode and reset your password.
