I'm new to linux. Currently I have 4 buntu-distros on my old Mac Leopard. Every time I try to multiboot with more than 1 EFI distro I'm stuck with boot issues (that is I can't boot). So I go back with only buntu-distros living together on my computer. ...let alone inexplicable (to me, because I'm not an experienced user) other issues that boil down to the following: some distros (a lot) I can't even open every time I insert my usb drive. In fact I have to say that the fail average diminished when I learned to burn a usb drive by terminal; yet a lot of KDE and fedora-distros are out of my "province").
Examples 1) Maui doesn't see my wifi, so I have to quit before start installing 2) KDEneon, SolydK, Korora, Fedora don't see my wifi, even if the installation worked "fine". 3) Chapeau (gnome GUI) doesn't display whenever I download and burn the ISO on a usb drive (3 or more times...). Of Chackra I couldn't even see the logo from the ISO.
PS In order to get a EFI distro, I have to avoid multibooting (Manjaro KDE worked fine for some days all alone on my Mac; same story with PClinux and a lot of other distros)
I know that all the trouble is all my fault. I keep on going bacause I like linux very very much.
