I have a Acer E1-570 with preinstalled Windows 8 OS. My wife tried to install a wi-fi booster device and since then the OS is not booting. I tried several things like changing the order of boot device in BIOS, typing F2/F10 etc while loading but the OS simply does not boot. I am thinking of buying the Windows repair USB/CD from amazon but was wondering if I will need the Windows 8 product key after the repair ? Since the laptop came with the inbuilt OS, should I be asking Acer to provide the product key ?
Any suggestions will be appreciated.
