As with many utilities today, it is possible to encrypt our entire hard drive from the moment we run its installation. The reasons for this can be various, from protecting our privacy to making sure there is no intrusion into our system.
In the following tutorial we will show you how to encrypt your hard drive data using a minimal system image of Ubuntu installation system. An easy way to secure your strange looking information.
First we have to get one image Ubuntu installation system minimum, the well-known network installation version or NetInstall. This method of installation has several very positive factors which make it recommended to others, such as that, first of all, the image is very light (barely weighs 50 MB) and downloads quickly with which we can begin our procedure in a few minutes; in addition, you will only need to download those packages that you will actually need within your system, so the time and space required will be just and necessary for your team; and finally, when downloading live packages, you will always have the latest version of each one.
Once the image has been downloaded, we will boot up our computer and start with the initial configuration steps: choose the language and select the layout of our keyboard.
The system will then perform hardware detection and, as we are in the network installation, it will try to automatically charge the network devices of our computer. Then we will select the mirror of the packages.
Then, the additional modules will be loaded needed to continue the installation process. We will set our username and password.
The system will warn us that encrypt our folder home will provide privacy to our data even if the computer is stolen, Since it has to mount this unit every time we log in to the computer and disassemble it when we leave it. Next, we will later select the time zone for our country.
Then, we will choose guided disk partition. Remember that it is not possible to set a dual boot of the computer and full disk encryption.
Enter the encryption key (A robust key is longer than 20 characters). Verify that the partitioning scheme is what you like and move on.
it is recommended select to have security updates installed automatically. And so begins the system installation where about 1500 packages will be downloaded, depending on the software we have selected and the type of desktop we choose.
Once the installation is complete, our unit will be encrypted and protected from any assembly other than our user.
