I have Ubuntu 14.04 on a 500 g hhd and Win 7 on an 80 g hhd for my security system. My question is how can I get the windows drive to keep accurate time? I've read that I need to go into the bios and change the time on the windows hhd. I am dual booting with grub. When I select windows at boot windows starts up w/o an opportunity to get into the bios.
