Linux Live CD

Since PC use BIOS and Macs use EFI instead, you may have to modify the live CD to use EFI in order to boot from it.

Try Ubuntu. Visit their site where they information on how to install on a Mac.

You want to dual boot Ubuntu, it's possible but it's best to use 10.10 and then once your up and going, then use the software update to get to 11.04 from within Ubuntu as there are more instructions for 10.10 online to help in your understanding things.

If you got new hardware is going to present some issues. Also you have to think about OS X Lion that's coming too, it's going to break things.

The 3D unity may not work, defaults you back to Ubuntu Classic, but you can install Unity 2D from the Ubunru Software Center.

Note that OS X Lion is going to introduce a "recovery partition" which could wreck HAVOC on a triple booting system.

Ideally you should first learn how to install Linux on a spare machine, this way you use a good one to get online and get help.

If you want to boot off a Linux CD on your Mac, the one I'm aware of that works is PartedMagic, and then only because it loads into RAM directly and spits the disk out. It's more of a recovery cd.

You burn a ISO of Linux to a cd using Disk Utility, or Windows 7 right click and burn, or the free ImgBurn for Windows.

A ISO is a disk image, so any OS can burn it.

You can use any distro you want, but it's safe to use one based on Ubuntu as that has the most drive behind it currently.

There is MacBuntu which looks like Mac OS X, it's based upon Ubuntu, but with a OS X like desktop, good for a old PC or netbook and you want to use a familiar looking OS.

Installing Linux on Mac is no easy task, it's a geeks right of passage, there is no "easy install" like Windows or OS X, although it has gotten considerably easier to do, but still requires more in depth education and learning that simply sticking in a disk and pressing install.

If you screw up, your machine can be bricked and your data lost.

Your going to need a wired internet connection to get your drivers during the install and afterwards.

Seriously, get a cheap used PC and start with that, at least you will have something to get online with when you do your Mac.

Also, don't look for reliable help on the Ubuntu forums, your going ot have to figure out a lot of things for yourself by reading the wiki's.

The clowns there will hack your box too, so better be careful. 😀

Yep. I've burned the .iso to a DVD. I've used various available tools to create a bootable USB flash drive. All work well on my Mac Pro as well as several netbooks. You will find this at the Ubuntu site:

Mac OS X

Note: To burn most ISOs, you can use Apple's Disk Utility (Disk Copy in older versions).

1. Launch Disk Utility (Applications → Utilities → Disk Utility).
2. Insert your blank CD/DVD.
3. Drag and drop your .iso file to the left pane in Disk Utility. Now both the blank disc and the .iso should be listed.
4. Select the .iso file, and click on the 'Burn' button in the toolbar.

1. Ensure that the 'Verify burned data' checkbox is ticked (you may need to click on the disclosure triangle to see the checkbox).
2. Click 'Burn'. The data will be burned and verified.

Would likely be the result of not making the DVD correctly. You may need to use a DVD because the live disc is bigger than a CD will typically hold.

Personally, I have better luck with Toast than DU when it comes to burning a .iso image.

I have attemped the same thing the month ago. It flashed me th infinitramp error so I virtualize it using the free Virtual Box.

hello,

this was possible (tested) till last white macbook without any problem, you could burn a livecd of every operative system efi and not efi, I tried ubuntu, xubuntu, gparted, backtrack etc.. starting from a specific firmware (I'm trying to identify) it seems this is not possible anymore
