Re: How do I install Fedora 17 as a dual boot with a different Linux distro?
You should have a separate partition for each distro IMO. When you get to the point where the installation wants to install GRUB, choose to install to / of the new installation partition rather than to the default MBR. This is how I do it. There are other ways though.
Fedora 18 Gnome on a ThinkPad X220, i5-2540M CPU, Intel HD Graphics 3000, Intel N 6205 wireless, and Sierra Wireless 754S Mobile Hotspot (AT&T)
