1- start your operating system (the below details Linux Mint but others are similar)
(it might take a while to read all the info from the disk)
2- click on the icon in the lower right corner that looks like a diagonal line with two balls in the middle and connect to your network
3- click 'menu' (lower left) then type 'gparted' in the search bar and select it
4- right click on the unused space you want to use and then resize the bar to approximately a new partition size, and then click 'add'
5- you are going to make three partitions. make one 10GB (this will be /) one 5GB (swap) and the remainder will be /home (for user data). make notes of what their designations are (/dev/sda?)
6- right click on a new partition and select 'format to -> ????' (whatever you want provided one is swap. I recomend ext4 for the other partitions)
7- click the enter arrow to apply operations
8- close gparted
9- open 'Install Linux Mint'
10- Select your Language
11- connect to your network
12- the next screen give some requisites for installation. select 'continue'
13- select 'something else'
14- select one of the partitions you created, click 'change', click 'do not use...' and select what you want to use it as. then click 'format partition' if you do not need to preserve your data. then click on 'mount point' (/ is root and everything else is self explanatory)
15- click 'Install Now' and away you go!
someone might want to make the above a sticky
