I used to run my Macbook in triple boot - Ubuntu, Fedora and Osx. When I turn the computer on, it goes to rEFIt menu and I could then choose between the OS's. Suddenly, it started to boot directly on Fedora's Grub menu. Now I can't boot in Osx or Ubuntu anymore. What can I do?

What happens if you intercept the boot holding down the alt [option] key after POST?
(POST = "Power-On Self Test; that is, the beep or, in a Mac's case, the "bong" sound that the computer makes after it has successfully powered on.)

Oh, I googled it and just found something related to http. The alt key prompted me into the Startup Manager menu, where I could choose beetwen Fedora and rEFIt. – panini Jul 08 '15 at 20:03
