http://askubuntu.com – I'm trying to dual boot Ubuntu 12.04 on my Macbook(which is a Mid 2007 model with Intel Core 2 dual and currently running Lion). I've burned the Ubuntu desktop iso file to a 4.7 dvd, installed rEFIt, and partitioned my hard disk to make room for Ubuntu, but when I put in the dvd and then reboot, the rEFIt menu shows only the "boot from Mac OS X" option instead of asking me whether to boot from CD. Holding down the key "C" or the option key doesn't help either. Could you explain how to fix this problem and get the laptop to boot from the DVD properly? Thank you very much! Eddy (HowTos)

Hi!

I recently downloaded and installed rEFIt and Ubuntu 12.04 on my macbook pro 6,2. I did this in the following order:

1. installed refit, rebooted to affirm it boots to refit. 2. downloaded Ubuntu (verified md5) and burned iso to DVD. 3. partitioned 60 GB of free space in disk utility 4. inserted DVD, rebooted, from refit boot screen booted to Ubuntu install DVD. 5.

Restoring rEFIt on Macbook Air 32 weeks 21 hours ago

My Macbook Air dual boots Mac OS X and Ubuntu Precise. Normally when you turn it on the first thing you see is the rEFIt menu which allows you to select which OS to boot. If you select Ubuntu then Grub will show up next, though Grub cannot boot Mac OS X.

Last friday I restarted Ubuntu and it skipped straight to Grub.

I'm looking to install Linux on my Macbook Pro in a Dual Boot config. I've previously asked this question in a different fashion here: Dual Boot Fedora 16 with OS X rEFIt.

However, it didn't really get much attention and seems to have fallen of the radar.

Tripple booting with Refit 19 weeks 6 days ago

I am currently working on a MAC that is dual booting Ubuntu 10.04 32-bit with MAC OS X (Lion I think) 64-bit via Refit; I never use the OS X partition because I can't stand the UI on Macs, my question is, if I were to try installing Ubuntu 12 64-bit onto this system, using another partition, would I use Refit to have three options when the machine loads up, or would I just use the pre-existing Ubu

as title says, this is my first time trying ubuntu.

Hello All,

Here is the deal. I'm trying to dual boot Snow Leopard and Ubuntu on an old mac I have (It's a 2008 Core Duo Plastic Blackbook, version 4,1). I just purchased a new hard drive, installed it and put Snow Leopard on. I then partitioned the hard drive and installed rEFIt, which worked great.

I am dual-booting Ubuntu and OS X on my mac.

I removed rEFIt because on another computer my mom nearly reformatted the hard drive by choosing the Windows recovery partition in GRUB (I was already on the way to school when she called).

So, without rEFIt, my mom will not be able to accidentally boot into Ubuntu and the only way to boot into Ubuntu is to hold option/alt at startup, which is OK beca
