Check the box to format the partition and make the mount point '/'. I chose to use the partition as Ext4, although you can pick something else if you want-Ext4 seems to be the new standard, so I'd recommend it if you don't know the difference between them all. You'll be presented with a window in which you manually set the partition's characteristics. If you've been following this how-to to the letter, it should be /dev/sda4. When you're presented with the partition window, choose the bottom option to 'Specify partitions manually'.Дouble click on your Linux partition's entry. Choose install, then go through the first few steps of the process, picking your language, time zone, and keyboard type (USA probably works fine, but I usually pick USA - Macintosh because, you know, that's what I have).

When it's done and you finally get to the Windows desktop, you can go ahead and install the Boot Camp drivers from your OS X installation DVD. It'll take a little while to install, and it'll restart a few times during that process-whenever it does, select the Windows partition on boot (which should show up in rEFIt now, so you won't need to hold option down again). It should reformat that partition to NTFS for you, after which you can hit the next button. You'll want to choose the one named WINDOWS (obviously), though you'll have to format it by clicking 'drive options' and then 'Format'. When you're asked what type of install you want to perform, choose 'custom install', so you can pick and format the partition. Go ahead and navigate through the first few steps of the installation.

Insert your Windows installation disk and restart your computer, unless you've already installed it, in which case, move on to installing Ubuntu.

The sizes don't particularly matter, as long as your OS will fit on the partition, and you have enough extra space for whatever you want. Format this Windows partition to MS-DOS, then make the size whatever you want.

Click on your first new partition (the one under 'Macintosh HD') and on the right side of the window, type 'WINDOWS' in the name box.

Next, hit the plus sign enough times so that you have four total partitions. If you have multiple partitions already, click on the one from which you want to take back some space. To do this, just click on your Macintosh HD partition.

Open it up and launch the installer package, and go through the installation process (which is pretty self-explanatory it'll do all the work for you).
