Last night I attempted to install Ubuntu to my secondary hard drive and dual boot Windows 10. It completely borked everything. Grub screwed me over. I think my grub is still messed up and I need to fix it. How would I go about install Ubuntu 15.04 to a secondary internal hard drive while still being able to boot to windows if need be on boot. Before windows 8 this was easy but with the way Microsoft changed everything it completely shoots me in the foot. I am installing the live iso to my usb by UNetbootin. Yes I have UEFI unfortunately.
