Dear Sir, I got a Windows_7_Ultimate_Activated_AIO.iso and would like to install on a blank HDD via bios mod,but I'm totally confused about the steps. Since I don't have an OS on my HDD,am I supposed to install the windows first before I proceed with the SLIC mod and stuff? Or do I have to get the slic mod and bios ready before the installation? If so how could I do it without an OS? Will be using a gigabyte motherboard fyi. Sorry if the questions sound dumb,just wanna make sure before I start. Thanks
