Portable operating systems can be copied to a USB stick to be started when the computer boots. This PC will then start with a different system than the one installed on the hard disk and will be completely independent of it.
One of these systems can be Chrome OS, the Google operating system that is used on Chromebooks.
The characteristics of this Google operating system are the loading speed, the lightness and the fact that all programs work only if the computer is on the internet because it is based on web applications .
Having an operating system like Chrome OS on the USB stick, it turns on in 10 seconds and is immediately functional for any type of operation.
In addition to Chrome OS there are also other Linux-based portable systems that can be booted from to a USB stick, with basic functionality for most users: web browsing, music and video playback, photo management and some games.
These operating systems are almost browsers and can also be used as programs on the main Windows PC to try them or to use them in order to launch your favorite web applications on the fly or even the normal programs in reduced versions.
Even on an old pc they could be ideal to make it work properly again.
After seeing the best Linux distro ever, we see the best Linux based portable operating systems, they are:
1) Puppy Linux cannot be left out of this list since I dedicated a large article to it more than a year ago.
Puppy Linux is a complete operating system of everything, with a normal desktop similar to Windows, with all the programs to do any job and that starts in a few seconds with unrivaled speed.
Since it can also be installed on a 128 MB USB stick, it is always worth keeping Puppy in the drawer because it becomes both a way to carry around your personalized settings so that you can use them on any computer, and an emergency system to restore Windows in the should it not light up anymore.
They are also ideal for continuing to use an old computer that will return to full efficiency with these light systems.
1 BIS) MacPup based on Puppy Linux, but much nicer to look at.
2) Lubuntu uses the Lightweight X11 Desktop Environment (LXDE) to provide a basic graphical interface.
While not the most beautiful of distribution here, Lubuntu is fast and functional and uses Ubuntu as a base, the system that best of all offers compatibility and full access to Canonical's repositories.
3) Tail and anonymous operating systems, which after use leave no trace on the computer.
4) ElementaryOS, the easiest, most beautiful and very fast Linux system ideal also for old and not very powerful PCs.
5) Pixel, the lightest, easiest-to-use operating system developed by the creators of the Raspberry PI.
6) Phoenix OS an operating system that brings Android to the PC an operating system that brings to the PC, Android (which has the Linux Kernel) complete, light and not very spacious, very easy to use, as explained in another article
7) TinyCoreLinux, a complete 64MB operating system, smaller than Puppy.
8) Slitaz is a 30 MB operating system and it really seems incredible when you think that programs like ITunes are three times bigger in size.
The smallest of systems, it can be installed on a USB stick and becomes a magnificent portable system.
9) Peppermint OS similar to Windows, ultra light with desktop and Web Apps, ideal for older or less powerful computers.
10) Prime OS is just Android for PC, an ideal open source system to use on older laptops or even the new one if you are tired of Windows and want a desktop interface similar to that of a tablet or smartphone.
Prime OS can be installed, if you want to try it, on a USB drive, on an SSD card, on the computer's hard disk or you can boot it from CD.
11) Bodhi Linux is based on the famous Ubuntu Linux, lightened and reduced.
This system is developed and updated by very active developers still in 2019, so it is currently reliable and promising.
12) SLAX is a 200 MB Linux version based on the Slackware distribution.
Slax is instead the most complete of this list because you can install all the programs you want.
It is therefore possible to create your own portable operating system with Slax in a simple and free way.
