Hi, I am currently dual-booting Ubuntu 15.10 and Windows 7.
I read somewhere that if I re-install/ clean install/ upgrade Windows, I will lose GRUB, and it will be replaced by Windows' own bootloader.
So, please give me a detailed explanation of how to re-install GRUB if I re-install Windows.
Usually, I do not get online before 1:00 PM or after 10:00 PM (my local time).
So, if I do not reply to a thread where I am currently active, make sure you check my local time to see if it's time for me to be online or not.
