Back to Advanced Partitioning Tool window, you can see the space that you just recovered from Windows 7 listed as free space. That free space is what will be used for creating Linux Mint 13 partitions. To start creating the partitions, select the free space as shown in this image and click Add. Note: This step will have to be repeated for every partition that you need to create.
You have seen this window before, but this time, you will be doing a little bit more on it, or to it. You already know that for this tutorial, four partitions will be created for Linux Mint 13. Be default, the installer will attempt to create the first and subsequent partitions as Logical partitions. You can stick with the default, or make the first Linux Mint 13 partition a Primary partition. For this tutorial, I chose to create the first partition, which will be the boot partition, as Primary. If the terms being used here are foreign to you, please take a moment to read guide to disks and disk partitions in Linux, if you have not done so already.
For the boot partition, you can specify the values and options shown on this image. If you are tight on disk space, you can go much lower than 500 MB for the size, but be sure to use /boot as the Mount point and leave the Use as value unchanged. OK.
For the root partition, the minimum disk space recommended is 5.2 GB, so any value higher than that should be enough. Since resizing the disk on a running system is not an easy task, be generous here. For this test installation, I gave it 20,000 MB, or 20 GB. OK.
The partition mounted at /home should be allocated most of the available disk space. If you were generous with disk space allocation to the root partition, be very, very, generous here. Depending on how you use the computer, this could fill up quickly. Leave the file system at the default and use /home as the Mount point. OK.
The last partition will be for Swap, disk space that the system may use as virtual memory. Select swap area from the Use as dropdown menu, and assign it a suitable disk space. For most systems, 4 GB should be more than enough. OK.
Back to the main Advanced Partitioning Tool window, you should see the partitions you just created. If you followed the partitioning scheme used for this tutorial to the letter, the partitions should be listed as sda3, sda5, sda6 and sda7. Not visible on this screen shot, are the pre-existing Windows 7 partitions, which are sda1 and sda2.
The final task that must be completed at this step before clicking Install Now, is to select the Device for boot loader installation. By default, it is sda or to be exact, the MBR of sda. You need to change that to sda3, which corresponds to the boot partition that you just created.
This is what the Device for boot loader installation dropdown menu should look like before you click Install Now.
After installation has completed successfully, the computer should reboot into Windows 7. Before Windows reboots, it will start checking the resized C drive for consistency. Let the check complete. After the check has completed, login. Since there is no way to boot into Linux Mint 13 until an entry for it is added to Windows 7′s boot menu, the next task is to download and install EasyBCD from here. After EasyBCD has been installed, start it. The main window is shown below. Click on Add New Entry tab.
While there, click on the Linux/BSD tab, then select GRUB 2 from the Type dropdown menu. GRUB 2, not GRUB Legacy, is the version of GRUB used by Linux Mint 13. Edit the Name field to match the distribution you are adding it for. Apply the changes by clicking the Add Entry button. Click on the Edit Boot Menu tab.
You should see how the entries will appear on the boot menu. Exit EasyBCD and restart the computer. Good or bad, let me know how you fared with this tutorial.
