Introduction to Bootable USB
. Note The bootable USB drive will work only on systems with UEFI firmware. A.) Turn on your MacBook and press the Option (⌥) key, you should see the Startup Manager, which allows you to boot from other disks. B.) Select the USB drive and press Enter. C.) When Grub loads, select “Try Ubuntu without installing” and press Enter. If you want to use your USB stick with an Apple Mac, you will need to restart or power-on the Mac with the USB stick inserted while the Option/alt (⌥) key is pressed. This will launch Apple’s ‘Startup Manager’ which shows bootable devices connected to the machine.
The USB driver has been famous for its portability and ease of use. While most users find themselves applying them for general tasks such as data transfer, backup, or storage between systems. But, only some people realize the complete flash drive's potential.
This article will explain some ways for unlocking that potential and detect new uses we may not have known were possible. Flash drives are used for several other things than only hold our photos through ultra-secure banking to self-contained Oses entirely.
These types of uses each have a single basic function among them that is bootability. Hence, the bootable flash drive will permit us for booting the system through a file system over a flash drive instead of our hard drive.
Our system contains a boot sector that includes details about its use on the hard drive. A volume boot record would include instructions on how we can run an OS or any other program. A flash drive should have a volume boot record, master boot record, and include a program or an OS that could be run for booting to a flash drive.
Primarily, we will get two advantages of using a bootable USB drive. These are mentioned below:
Data and System Recovery
A bootable flash drive can be used for recovering a failed system if the operating system doesn't load on an internal storage drive.
Examples of Bootable USB Drive
A few best bootable flash drive examples include running an OS installer such as OSX, Windows, or even a few Linux forms. Probably, it is one of the most basic uses of any bootable USB drive. This feature was restricted to DVDs and CDs not several years ago, but it became feasible for placing these OS installers on our USB drive entirely as the memory technology of flash drives improved.
If our system is a new build, or if our system becomes unusable through a compromised or corrupted OS, then we can make use of a bootable USB drive for installing the operating system. We can restart and use our system as normal after all files will be copied to our system.
Sometimes, if an operating system such as OSX or Windows becomes compromised, then we can use a bootable install USB for rebuilding only the broken or missing elements without doing a complete system reinstall.
Note: The procedure of creating this operating system installer somewhat varies from the operating system to the operating system.
- Another very helpful, though less utilized bootable USB drive, will be a utility drive. Ultimate Boot CD and Hiren's Boot CD were both best tool examples contained on the CD that can test hardware, diagnose problems, partition hard disks, and replace or repair software out of the native OS.
- Then, UBCD and Hiren's were installed over a bootable flash drive, enabling these into portable and durable repair tools within our toolkit. Also, it included data repair and virus scanning tools that were simply thorough as they can shift from the information on our hard drive without running the erroneous commands included therein.
- If we have ever experienced malicious, spyware, or malware code on our system, then we know that the main goal of these viruses is to hijack our system and run many commands using the operating system.
- In such cases, a bootable utility drive can negotiate and pull out the malware without requiring to run an included code on the affected disk.
Both of the uses we've discussed so far think that our system is in a disrepair state. In this situation, we can install the LiveCD release of anyone of the 305 plus distributions of Linux available today.
As we all know that Linux OS is an open-source OSes family designed for replacing privately-owned OSes and wanted to be publicly maintained and licensed. On the flash drive, a LiveCD of Linux will permit us for experiencing an OS while keeping our current setup.
It is the best way for discovering if a specific distribution of Linux is a nice choice for us or our enterprise. We can breathe life into previous hardware via installing a Linux build, gaining a completely functional operating system with every tool we use now with every flavor of Linux available.
Why we select Ubuntu?
We know about Windows that is practically one of the most popular operating systems across the world, paralleled by the MacOS only. Hence, a question comes here, why should we select Ubuntu OS and not a well-known and famous version?
Firstly, having a windows OS doesn't stop us from having Ubuntu also. We can give the dual-boot installation or instead have both over the PC. It permits us to make a selection all time we turn over the device. Then, over time we may select to delete the one we find less usable and it is a good solution for those users who still have doubts about making a bootable USB of Ubuntu operating system for their system.
Although, there are many reasons that cause to prefer Ubuntu OS. Some of these reasons are listed and explained below:
- Cost: Ubuntu OS has no cost as it is free. This operating system was made by those who work for common welfare for free.
- Security: An OS that doesn't permit us for getting any virus or malware because all changes that we wish to implement on one file on our PC should contain the password. Hence, the password is not similar to rejected access.
- One of the best teams that operate together in cooperation.
- An organization behind it, a community, a developer team, and a foundation that works all days on the OS for improving it constantly to make it perfectly work.
- Simple: The Ubuntu operating system is easier to install and easy to use as well. The classic apps are already unified into the system. Hence, we have an operating system for which we don't have to pay anything. Therefore, Ubuntu USB can be the solution to our problems.
- High performance: Ubuntu OS gives high performance to our system and no restart is required for a basic installation unless we're updating a huge segment of the OS.
- If we get any issue from a bug or malfunction, then we can request help and the Ubuntu community, which is composed of many programmers, will help us to solve that issue for free. Also, we can contact these programmers with any questions.
- This OS can adapt to a device we have. It does not matter if we have the old PC or the latest generation PC, the entire software will Implement in its best way.
- Ubuntu OS already contains various pre-installed software. Also, it contains the SSH client that permits us to create an SSH connection.
Why establish an Ubuntu Bootable USB?
Making it an unusual selection is a benefit definitely since the operating system installation would not affect the main disk's partitions that we find in the system in any way.
The operating system usually already installed is saved in them. We could occupy outer space and have high performance in this way.
Installation of Ubuntu USB on Mac Systems
As we have discussed that the Ubuntu OS can be installed and used on any kind of system even those generated by Apple. So, here is every step we need to remember for creating a bootable USB of Ubuntu for a Mac system.
Booteable Usb For Ubuntu From Mac Os
Before detecting the steps for creating a bootable USB of Ubuntu we need to understand the essential requirements to get the action done with a working software perfectly.
- First of all, we need to establish a disk image over a pen drive.
- An Ubuntu ISO copy is present on the official site (we will need to select the version of Ubuntu as there are many distributions of Linux.
- We need to have a pen drive, at least a 2 GB flash drive, or a USB stick.
A computer or PC with 3.0 or 2.0 USB ports.
Note: If we have any Mac after 2017 or 2018 see if it includes the T2 chip. It would not be possible if present for booting Ubuntu through USB and we can't install Ubuntu OS in other partitions.
See if we have a Mac using T2
Since 2017 or 2018, Apple has begun using a T2 chip. This chip enhances the security of the system according to them. It is not possible to use an OS other than a Mac OSX.
Preparing our USB for installing Linux
If we are doing a task on an Apple system then for ensuring maximum capability we would initially need to format a USB stick. For doing it, we can make use of a unique tool which is given by Apple known as 'Disk Utility'. Although, if we wish to use a drive as common hardware we could skip this process.
- We need to first open the Disk Utility, we can find it inside our applications and upon utilities.
- Insert the USB flash drive and we can automatically check it through the application we opened very recently.
- Choose the flash drive and then choose Erase again over the toolbar.
- Enter MS-DOS (FAT) in the column of format and GUID Partition Map inside the scheme column.
- Once we have verified all the steps, then we can choose the Erase option.
It is an open-source and free application that permits us to specify the ISO file, which we will notice we need for installing Linux later on USB.
This procedure is straightforward through the official website we can download the app and execute it. If we wish we can also put it inside the folder of the app on our PC or leave it where it is exactly.
Note: Also, Whale Etcher is available for Linux and Windows.
To ignore being blocked via the Mac OS we could turn on an option, i.e., 'App Store and identified developers' from the control panel. After that, we need to select the 'Security and privacy' option which we will find inside the System preferences. We need to choose the 'Open anyway' option when a warning occurs.
We will now need to deal with the configuration. It will specify to our USB device within three distinct steps that we will need to choose when it is time for doing so:
- Choose image: In this situation, we will need to choose the ISO file we downloaded previously, which we will see inside a folder, i.e., Downloads.
- Choose drive: It permits us to choose the destination file. We must choose our USB flash drive at the point. We will get a warning in case it is not big enough.
- This step would start as soon as the drive and the image have been chosen.
We will be asked for the password of Etcher to type to continue.
The writing of our device will begin at this point and we can always monitor and check it.
After the process of writing, there will be a phase of validation of many contents in our USB. Etcher will disclose that the process is successfully completed after this process.
We will have made our Ubuntu bootable USB to use on our Mac after this process. In case we wish to use our USB stick on the Apple Mac, then we will need to turn on or restart the system keeping that USB stick put while pressing the alt/Option.
It will start the Startup Manager and our USB flash drive will represent the EFI Boot name, once chosen the menu would boot along with Ubuntu. We can now boot (start) our system with the operating system we installed over the USB.
The second option for Ubuntu bootable USB
First of all, we should note that we need to fix the boot mode through the USB stick for booting the operating system using a pen drive inside the PC bios.
We used DVDs and CDs in previous time but now USB drives are long-lasting. They have more memory and are smaller. We will download the following software for installing Linux Ubuntu operating system on USB:
- A software, i.e., UNetbootIN permits us for creating a disk image in some steps on the USB stick.
- The Ubuntu ISO image copy is present on the Ubuntu official website (we will need to select the version of Ubuntu as there are many distros of Linux).
The initial step is to begin the UNetbootIN software and then click on YES to proceed to the home page.
On this page, we need to choose the Disk Image option and select ISO from a drop-down menu.
We will see a button along with 3 dots on the right-hand side.
Press the button to choose the ISO file that we should have shortly before downloaded from the website of Linux Ubuntu.
Go ahead once selected and choose USB Drive through the Type menu. Then, we need to insert our flash drive into the USB port on our system. After that, locate the system and click OK to begin.
We just need to wait at this point for the process to be completed. Now, we will need to reboot the system along with the USB drive inserted to begin Ubuntu.
Note that Ubuntu OS will not start if we haven't set the USB in the bios as the main boot. If we haven't already implemented so, we must reboot the system, authenticate the bios, and choose USB as the main boot in the section corresponding to the operating system.
How to establish a Ubuntu flash drive for Windows OS and other OSes
Bootable Usb For Ubuntu From Mac Usb
If we wish to establish a Ubuntu bootable USB and we have a Windows OS system, then the process will be quite similar as the programs we described above are existed for Windows as well.
It is the proper process for implementing if we wish to establish a Ubuntu bootable USB, for use on many devices that make use of the Windows OS.
The first step
As in this type of case, verification is the first step to take that we have all the essential requirements for creating a Ubuntu bootable USB.
Hence, let's proceed to:
Boot Ubuntu From Usb Macbook Pro
- Have a system with 3.0 or 2.0 USB ports.
- Verify that we have the USB flash drive along with at least a free space of 2 GB.
We can now dive into establishing a Ubuntu bootable USB when we have already verified these above steps.
As we have seen corresponding Mac PCs and even Windows PCs don't need several steps. Practically, it is identical and the procedure is simple.
Hence, the initial step is to input our USB drive into a USB port on the PC.
Now, we are going to check for Ubuntu official website once it is done by using a search engine.
Also, we are going to choose the Ubuntu USB version that we wish to download inside the Download section. For choosing it, all we need do is press a button, i.e., Download. We will be reached on a fresh page at this point where we can do a donation for the entire team or proceed with the download.
Move the ISO file to the USB drive
A file is known as an ISO file that would be downloaded along with a copy of Ubuntu. All we need to do is transfer the file to our USB key at this point.
We can pursue the steps for Whale Etcher which are mentioned above for this operation.
However, we need to be careful because the files on the USB drive would be removed. So, we need to ensure to do keep the backup before going to begin the installation process.
The final procedure
All we need to do is eject our USB flash drive and see that everything is saved and present when the installation process is completed. We will need to jump on the final procedure if everything is going well which is to restart the operating system.
Now, let's input the USB drive into our PC and then start the computer. We need to repeatedly click on the F12 key on the logo screen, choose our key, and begin the process.
The key might be different in different computers. If the F12 key is not working, we can Google which key to use of our computer model.
We will be prompted if we wish to install Ubuntu OS on our device. If we wish to keep the OS just on the USB we need to choose the 'Try Ubuntu' option, which means we can give a try to Ubuntu OS without the need to install it.
Now, we are officially using our new Ubuntu OS on USB.
