I've managed to persuade my friend to give Ubuntu a try. He's running Windows 7 on his system. I'm going to tell him to sign up on the Ubuntu Forums, but I'd also like to be able to provide support, if he runs into any problems while attempting to dual-boot. I've suggested that he burn an Ubuntu LiveCD and test it out on his system before going for the installation. Now, what I would like to know is if there are any differences in dual-booting when a system has UEFI? His motherboard has UEFI. To my understanding, UEFI is supposed to be a replacement for BIOS? I'd basically like to know how to dual-boot Ubuntu with Windows 7 on a system with UEFI. Any help is appreciated!
