I did this setup due to Kernel upgrade bug:
GRUB_DEFAULT = 4
Than I executed
However, it didn't work out. My desired version is 4.2.0-16-generic, because 4.2.0-18 and 4.2.0-17(which actually isn't listed) doesn't work. In the list, 4.2.0-16 is 4th.
When it didn't work, I tried this:
GRUB_DEFAULT = "Advanced options for Ubuntu>Ubuntu, with Linux 4.2.0-16-generic"
however, it still didn't work and opened a not-working version of kernel. Currently I can only access 4.2.0-16 manually through Advanced options for Ubuntu, but I want it to load automaticly. What solution would you reccomend me?
dpkg --list | grep linux-image outputs:

as a last 4 outputs(only ones for Ubuntu 15.10 which contains Kernel 4.2.0).
