So I am getting real tired of Ubuntu. I want to switch to Arch, but keep my old Windows 7, and Ubuntu installs for future use. I was wondering how easy it was to install Arch along side the two other operating systems. Do I have to change anything with my boot loader? I am currently using the default GRUB that comes with an Ubuntu 13.04 install. It may be worth noting that I do not have a separate home and / directory, so I will have to make all of my files separate. Thanks!
