Hey guys,
I'd like to upgrade from Kali 1 to Kali 2 but I already have 2 OS installed on my HDD. First is Kali 1 and 2nd is Windows 7 and I'm using GRUB to choose which OS I want to boot. So, my question is, can I uninstall Kali 1 without interacting with Windows partition and then install Kali 2 at Kali 1 partition? It's very important so I have to be sure that Windows files won't be affected.
