This example uses Linux Mint 14 Cinnamon, but it is equally applicable to the MATE, Xfce and KDE editions (though KDE will look a bit different). I'll partition an empty 250 GiB hard disk, create a root partition, a separate home partition, and a swap partition. The steps for this are described below, with hints for slightly different situations. You can click the screenshots to zoom in, if needed.
- During the "Installation type" step of the installation, select to do "Something else".
- If this is an empty hard disk, or if you want to use the entire hard disk for Linux Mint, click "New Partition Table". You should skip to step 4 if you have partitions on your hard disk that you want to keep.
Hint: if you have another operating systems installed, it is generally easier to use either its partition manager, or use the GParted partition manager included with Linux Mint, to make free space available (by resizing existing partitions) to install Linux Mint on before you start the installer.
- Click "Continue" to erase all current partitions and create a new partition table.
- Click the "free space" in the list to highlight it, then click the "Add" button to create a new partition in this free space.
Hint: if you have existing partitions that you want to reuse, click those to highlight them and then click the "Change" button. Generally, you will want to set to use as an ext4 journaling file system, tick to format the partition (not needed for swap), and set the mount point as per the following steps (not needed for swap). If you do not want to erase the current files on the partition, do not tick to format the partition and make sure the file system you set matches the current file system used.
- First I'll create the root partition. Set the new partition size to how big you want it to be in megabytes (1 gigabyte = 1000 megabytes). I've configured 30000 megabytes (30 gigabyte), which is reasonable for average use. Set the mount point to / (forward slash), to indicate this will be the root partition. The other fields you don't need to change unless you have reason to. Click the "OK" button to create the partition.
- Next I'll repeat steps 3 and 4, to create the home partition. Set the new partition size to the remainder of the free space, but subtract the size you want for your swap partition (subtracting between 4000 and 5000 from the number shown will generally be enough). Set the mount point to /home, to indicate this will be the home partition.
Hint: you can always change or delete the newly created partition if you made a mistake, and you can resize partitions later if you need to. You can do that by booting from the Linux Mint installation DVD or USB stick, and using the GParted partition manager.
- Next I'll repeat steps 3 and 4, to create the swap partition. Set the new partition size to the remainder of the free space, as in step 6 you deliberately left some free space for the swap partition. Set it to be used as swap area. You don't need to set a mount point.
- You can now review the partitions you created before you continue with the installation. Also, you have the option here to select where to install the boot loader. The default is fine if you have no other operating system installed or if you want Linux Mint to ask you at boot time which operating system to boot.
If you want another operating system to ask you at boot time which operating system to boot, then change the device for boot loader installation to your root partition (/dev/sda1 in this example). Note that without additional software, Windows isn't able to ask you which operating system to boot.
