I'm not happy with my installation choices with Mint Cinnamon 18.1.... so how do I UN-install it? Completely remove it, so I can study it better on live disc and decide partition setup later?
The best and safest way, and the ONLY WAY that I always do that is this:
1. Use either Acronis Home or DBAN to do a deep delete of your hard drive(s) and/or SSD(s).
2. Boot from live disc (USB or DVD/CD), partition your drive(s) as follows:
Create 3 partitions if you only have a single drive in your system.
First partition, type EXT4 of at least 20-25GB for your Linux system files mounted as "/" (aka the ROOT PARTITION)
Second partition of 2GB (2048MB) type Linux swap for your system swap
Third partition, the remainder of the drive, type EXT4 for your home folder (personal data files) mounted as "/home"
If you have more than one drive in your system, use the fastest one (an SSD preferably) for your ROOT PARTITION and use the other one for both swap and HOME.
You can add a 3rd, 4th, etc, formated EXT4 and mounted as "/media/ANY-NAME-YOU-WANT-TO-GIVE-IT"
For example, I have 3 storage hard drives, which I mounted as:
Complete the install and enjoy. Good luck!
NOTE: A partition name CANNOT contain any blanks (keyboard spacebar character) in the name.
5TB Linux Storage would be incorrect, it needs to be 5TB-Linux-Storage or 5TBLinuxStorage or 5TB_Linux_Storage
