Re-Brand Debian Name to Custom Distro Name in GRUB on 1st Install

[Pak OS <gsm.pakos@gmail.com>]

Hello All, 

I have been trying to change name of my custom Distro from Debian as per these guidelines:

https://wiki.debian.org/Derivatives/Guidelines#De-.2FRe-branding

However despite changing output of lsb-release, /etc/issue and related files , when ever I do a fresh install of my OS, its always Debain. 

However, if I install a new OS on another partition, my old installed OS is correctly reconginez as PakOS(name of my custom Distro). 

Please help, any idea where Grub is getting Debian name on 1st time installation. 

Thanks in advance for your help. 

Regards,

gSM
