If you want to dig deeper, you can choose another LiveUSB Linux, such as Manjaro, Debian Live, Mageia or Porteus.

In the meantime, go to rufus.ie and download the portable version:

  • Using both the pointer or arrow keys on the keyboard, pick out the USB power you want as well from.
  • Once decided on, either hit the Return key or double-click your selection. The gadget will start to boot from the USB power.

Now you can enjoy your PC is ready for MAC operating system and you can use it.

Some Linux distributions can be test without installing them on your hard drive; they are referred to as LiveCDs, or LiveUSBs. All you need is an empty USB stick with enough space (at the very least 4GB). The same method also applies to any other Linux system if you are only interested in installation.

First, download the CD image file (.iso) with your desired distribution. One of the go-to beginner distributions is Ubuntu, which can be downloaded at  https://ubuntu.com/download/desktop

If you want to dig deeper, you can choose another LiveUSB Linux, such as Manjaro, Debian Live, Mageia or Porteus.

In the meantime, go to rufus.ie and download the portable version:

Make sure your USB stick is plugged into your computer. Launch the downloaded rufus-x.yp.exe. If User Account Control asks for permissions, choose ‘Yes’. If Rufus asks for updates, choose ‘No’.

You will be greeted with a small window. The “Device” list should be listing your pen drive. If several are connected, choose the correct one. Next, press the ‘SELECT’ button and choose the Linux .iso you have previously downloaded. The window should look similar to this:

Double check the pendrive doesn’t have any data that hasn’t been backed up, and hit ‘START’.

Restart the PC and go to the BIOS. This can be do it by repeatedly pressing a key display on the boot screen. Look for boot order, and choose to boot from USB. You will then be greeted by your Linux distribution.

How To Boot Linux From USB

First, let us create a bootable Linux USB drive using UNetBootIn.

  • Visit https://unetbootin.github.io/ to download UNetBootIn.
  • UNetBootIn allows to load the OS either by downloading an ISO or by using an existing ISO on your system

To create an bootable Linux USB drive:

  • Insert USB Flash/Pen drive (please note, any existing data from USB will be delete during below process.)
  • Run UNetBootIn
  • Loading ISO
  • If you already have an existing ISO on your system, select Diskimage option & provide it with ISO file

  • If you do not have an existing ISO on your system, select Distribution option & select the OS & Version of your choice
  • Select Type: USB & Drive in which you wish to load OS & press OK

  • Wait for it to complete the process. Once completed, your bootable USB is ready.

Now, let’s boot your system from USB

On Windows:

  • Power off the computer & insert the bootable USB drive
  • Power on your computer & enter BIOS setup (depending upon your computer make, press ESC, F1, F2, F8 or F10 immediately after powering on to enter BIOS setup)
    • Some BIOS make allow to select booting option without entering in to setup utility. In such a case you may skip step 3 & 4
  • In the setup utility, select BOOT menu & move USB / Removable  Device to be the first in booting sequence*
    • Some make list USB / Removable Device under Hard Drive Devices.
    • In such cases,
      • Move Hard Drive Devices to the top of booting sequence
      • Expand to show all hard drive devices
      • Move USB device to the top of list
  • Save changes & exit BIOS setup
  • Now the computer will restart with new settings i.e. booting up from USB
    • You may be prompted with “Press any key to boot from USB / external device”, so press any key quickly or else it will skip to next boot device
  • Follow on screen simple instructions to boot from USB

* Going forward, your system will always try to boot from USB first. You may want to roll back BIOS changes executed in step 3 as & when required.
