Click here to create a USB flash drive with Linux Mint using Universal USB Installer.
Connect the USB flash drive to your PC and power on the PC.
On the Mint Desktop, click on the disc icon Install Linux Mint.
Select your language and click Continue.
If your system meets the system requirements, select Continue.
At the next step, it is important that we select Something else. Click Continue.
Click on the New Partition Table button, and a pop-up box appears. In the pop-up box, select Continue.
Under /dev/sda, we now have an option free space. Highlight the free space option, and click on the + (plus) icon. The Create Partition pop-up box appears. Commit 75% of the total available space to this partition. Set the mount point to / (root), and click OK. This becomes /dev/sda1.
Highlight the free space option again, and click on the + (plus) icon. The Create Partition pop-up box appears. Dedicate 4096 MB (4 GB) to the swap area. Ensure this partition is set as Primary and use as Swap Area. Click OK. This becomes /dev/sda2.
Highlight the free space option again, and click on the + (plus) icon. The Create Partition pop-up box appears. The last partition is for our /home directory. Ensure this partition is set as Primary and set the mount point to /home. Click OK. This becomes /dev/sda3.
Click Install Now.
Select a well known city in your Time Zone. Click Continue.
Complete the form. Click Continue.
There will be a prompt that the installation is completed. Although it seems reasonable to Restart Now, instead select Continue Testing. The reason we do this is because we need to change the Boot Order in BIOS. Select Menu > Shut Down Linux Mint.
Power on the PC, enter BIOS, change the Boot Order to boot from the device that Mint was installed on, and boot.
You should now get the Mint Desktop, and the install Mint option no longer appears.
