How to install Linux on a USB pen bootable from ISO, live for use on all computers or to install a new system
Instead of continuing to use Windows 7 or 8 as an old laptop's operating system, it might be a wise choice to install a lighter Linux operating system that could bring the old PC to life.
Certainly, a person used to Windows can not recommend to forget Microsoft forever and install a Linux distribution as the only operating system.
Also I do not even want to recommend dual boot procedures, both because they require a little 'experience, both because, if you think of a portable netbook or an older PC, it is likely that there is not a hard disk with sufficient space.
So the solution is to install Linux on a USB stick with an operating system "Live "that is, it resides in memory and does not write anything on the hard disk of the computer.
The Linux Live CDs were popularized to sponsor the open source operating system so you can try it without hitting it.
The USB live pen is the same thing, with the advantage that it also works on laptops without a CD player and that also allow you to use the pen space to save new data and modified files.
The less experienced could imagine who knows what procedures to install Linux on a USB stick that then will have to be made bootable at boot of the computer.
Luckily there is a program that does everything by itself automatically and that creates a bootable USB pen with Linux , any version or distribution you want ( Di Linux there are in fact many different distributions ).
Universal Netboot Installer ( UNetbootin ) is the most popular portable program for Windows Mac and Linux from which it is easy to download and install various distributions of Linux in a system partition or USB drive without any need to burn the ISOs of the distributions ( ISO are the images CDs with operating system installation files).
With Unetbootin you can install Linux on a USB stick.
The program is very easy and just choose the Linux distribution from the first list and then the version in the second menu.
The list includes Backtrack, Ubuntu, Linux Mint, Fedora, Gentoo, Xubuntu and many others including Puppy Linux, the smallest, of which I had written the installation guide.
For each distribution there is a link to the system homepage and two lines of information.
Just insert the USB stick and press OK to start the automatic download of the Linux distro chosen and proceed with the installation in the USB stick (choose the letter from the last menu correctly).
Optionally you can select the USB image from the computer's hard disk to install from a file already downloaded or to try a version not present in the list.
A program similar to Unetbootin is Universal USB Installer portable application for Windows only.
Attach the USB stick (at least 2 GB) to the computer, start the program and choose, from the drop-down menu, the Linux distribution you want to install.
After selection, you can select the download option that will open the browser and start downloading the ISO file.
After downloading, you can indicate the position of the ISO image in step 2, choose the letter on the USB stick, choose to format it and then indicate the amount of space to be reserved for the system in the pen (so if you want to use an external hard disk it can also be used as normal file storage).
In the end, after a short time and with a very fast procedure, you can create the portable operating system.
The peculiarity of Universal USB Installer is not only the amount of distrubutions and versions supported, many more than Unetbootin, but also the presence of Installer.
Basically you can create a USB stick that becomes like a CD of installation of an operating system and that can be used to install Linux even in dual booting computers that do not have a CD-ROM drive.
From Universal USB Installer you can also create a USB of Windows 7 or Vista installation to install Windows from USB stick.
