I have a new machine and I planned on running win 8 on one partition and the second partition Ubuntu. I already have a leagal of win 8 on the box.After I install Linux I need to install a pci card for the linux side.What Im wondering is once I install this card,wont it break windows8 from booting because the hardware has changed?And if it dont boot is there a way to call microsoft to get win8 back up ???
