Select Mac OS Extended (Journaled) from Format dropdown. Type BigSur or any other name you like. Make it simple because you will use this name in the next step. Click Erase and wait until the media is erased. Step 3: Making the Bootable Media. Now open Terminal and type the following command. Make sure you don’t leave any spaces. Obviously, then, you want to create your bootable install drive using the latest version of the Mountain Lion installer. However, unlike with other Mac App Store-purchased software, the Mac App. How to Boot Mac from USB Media. After creating a bootable USB drive, the user simply needs to plug the created drive into the open port on the Mac. Here are the steps to boot Mac from the USB flash drive: Power on the system. Press and hold the Option (Alt) key on the keyboard when the computer starts. Go ahead and use these simple steps to make all your USB drives unbootable & restore it to original states. Stay tuned for the next posts on how to format bootable Pendrive in Ubuntu Linux. Feel free to share your thoughts and also tell us if you know any better way to Convert Bootable USB to Normal in Windows 10 & macOS.
When OS X shipped on a DVD a good number of years ago, you always had the convenience of a bootable installer—an OS X installer that could be used to boot your Mac if its own drive was having problems. But to install or reinstall a recent version of OS X, you must either download a non-bootable installer from the Mac App Store or (via OS X’s invisible, bootable recovery partition) download 6GB of installer data from Apple’s servers during the installation process. In other words, you no longer have the same safety net or convenience.
Because of this, I recommend creating your own bootable El Capitan (OS X 10.11) installer drive on an external hard drive or USB thumb drive. If you need to install El Capitan on multiple Macs, using a bootable installer drive is faster and more convenient than downloading or copying the entire installer to each computer. If you want to erase the drive on a Mac before installing El Capitan, or start over at any time, you can use a dedicated installer drive to boot that Mac, erase its drive, and then install the OS (and subsequently restore whatever data you need from your backups). And if your Mac is experiencing problems, a bootable installer drive makes a handy emergency disk.
(OS X Recovery lets you repair your drive and reinstall OS X, but to perform the latter task, you must wait—each time you use it—for the entire 6GB of installer data to download. At best, that’s a hassle; at worst, it’s hours of waiting before you can get started.)
As with previous versions of OS X, it’s not difficult to create a bootable installer drive, but it’s not obvious, either. I show you how, below.
Keep the installer safe
Like all recent versions of OS X, El Capitan is distributed through the Mac App Store: You download an installer app (called Install OS X El Capitan.app) to your Applications folder. In this respect, the OS X installer is just like any other app you buy from the Mac App Store. However, unlike any other app, if you run the OS X installer from that default location, the app deletes itself after it’s done installing OS X.
If you plan to use the OS X installer on other Macs, or—in this case—to create a bootable installer drive, be sure to copy the installer to another drive, or at least move it out of the Applications folder, before you use it to install the OS on your Mac. If you don’t, you’ll have to redownload the installer from the Mac App Store before you can use the instructions below.

What you need
To create a bootable El Capitan installer drive, you need the El Capitan installer from the Mac App Store and a Mac-formatted drive that’s big enough to hold the installer and all its data. This can be a hard drive, a solid-state drive (SSD), a thumb drive, or a USB stick—an 8GB thumb drive is perfect. Your drive must be formatted as a Mac OS Extended (Journaled) volume with a GUID Partition Table. (Follow this tutorial to properly format the drive if you’re using OS X Yosemite or older. If you’re using OS X El Capitan, use these instructions.)
Your OS X user account must also have administrator privileges.
Apple’s gift: createinstallmedia
In my articles on creating a bootable installer drive for older versions of OS X, I provided three, or even four, different ways to perform the procedure, depending on which version of OS X you were running, your comfort level with Terminal, and other factors. That approach made sense in the past, but a number of the reasons for it no longer apply, so this year I’m limiting the instructions to a single method: using OS X’s own createinstallmedia tool.
Starting with Mavericks, the OS X installer hosts a hidden Unix program called createinstallmedia specifically for creating a bootable installer drive. Using it requires the use of Terminal, but createinstallmedia works well, it’s official, and performing the procedure requires little more than copying and pasting.
The only real drawback to createinstallmedia is that it doesn’t work under OS X 10.6 Snow Leopard—it requires OS X 10.7 Lion or later. Though it’s true that some Macs still running Snow Leopard can upgrade to El Capitan, I think it’s safe to assume that most people installing OS X 10.11 will have access to a Mac running 10.7 or later.
(If you absolutely refuse to go near Terminal, an El Capitan-compatible version of DiskMaker X is now available, although I haven’t yet had the chance to test it.)
Making the installer drive
- Connect to your Mac a properly formatted 8GB (or larger) drive, and rename the drive
Untitled
. (The Terminal commands I provide here assume that the drive is named Untitled. If the drive isn’t named Untitled, the procedure won’t work.) - Make sure the El Capitan installer (or at least a copy of it), called Install OS X El Capitan.app, is in its default location in your main Applications folder (/Applications).
- Select the text of the following Terminal command and copy it. Note that the window that displays the command scrolls to the right.
- Launch Terminal (in /Applications/Utilities).
- Warning: This step will erase the destination drive or partition, so make sure that it doesn’t contain any valuable data. Paste the copied command into Terminal and press Return.
- Type your admin-level account password when prompted, and then press Return.
- You may see the message “To continue we need to erase the disk at /Volumes/Untitled. If you wish to continue type (Y) then press return:” If so, type the letter Y and then press Return. If you don’t see this message, you’re already set.
The Terminal window displays createinstallmedia’s progress as a textual representation of a progress bar: Erasing Disk: 0%… 10 percent…20 percent… and so on. You also see a list of the program’s tasks as they occur: Copying installer files to disk…Copy complete.Making disk bootable…Copying boot files…Copy complete. The procedure can take as little as a couple minutes, or as long as 20 to 30 minutes, depending on how fast your Mac can copy data to the destination drive. Once you see Copy Complete. Done., as shown in the screenshot above, the process has finished.
Createinstallmedia will have renamed your drive from Untitled to Install OS X El Capitan. You can rename the drive (in the Finder) if you like—renaming it won’t prevent it from working properly.
Booting from the installer drive
You can boot any El Capitan-compatible Mac from your new installer drive. First, connect the drive to your Mac. Then, restart your Mac (or, if it’s currently shut down, start it up) while holding down the Option key. When OS X’s Startup Manager appears, select the installer drive and then click the arrow below it to proceed with startup. (Alternatively, if your Mac is already booted into OS X, you may be able to choose the installer drive in the Startup Disk pane of System Preferences, and then click restart. However, sometimes OS X installer drives don’t appear in the Startup Disk window.)
Once booted from your installer drive, you can perform any of the tasks available from the OS X installer’s special recovery and restore features. In fact, you’ll see the same OS X Utilities screen you get when you boot into OS X Recovery—but unlike with recovery mode, your bootable installer includes the entire installer.
Linux is a great open-source operating system that can be installed on any desktop or laptop. What sets Linux apart from Windows and macOS is that it has a number of different versions that suit all your needs, ranging from newcomers to hard-core users. We call these versions distributions. The best part is that you can download all of Linux's distributions for free and install them on multiple machines.
One of the most popular Linux distributions is Linux Mint. Each distribution serves as a different purpose and there is no exception to Mint. Basically, Linux Mint is specifically designed to produce a modern and elegant operating system which is very easy to use. The coolest part is that a Linux Mint stick can be created from macOS and Windows, meaning that you can boot from Linux without installation.
In this guide, we will show you how to create a Linux Mint bootable USB in Windows 10 and macOS. Before we proceed, there are a couple of things you need to understand about Linux Mint.
Why Linux Mint?
Linux Mint is one of the most used Linux distributions out there, as it is free and reliable. Like other distributions, Linux Mint can be installed on all platforms, including macOS, Windows, Android, and iOS. Linux Mint is widely supported by community and developers. The best thing about Linux Mint is that it is not vulnerable to viruses and malware attacks, which is ideal for testing purposes.
Creating a Linux Mint bootable USB is a no-brainer if you want to use it on a different computer. However, the process may be a little bit confusing to some folks. With that in mind, we are here to help.
Create Linux Mint Bootable USB on Windows PC
Windows is the most popular desktop OS and there are many apps that are capable of creating bootable Linux Mint USB installer. In this section, we pick up the best three one based on our testing.
1. UUByte LiteBoot
There are a lot of Windows users that are planning to give a try on Linux Mint. So at the beginning, we are introduing a couple of methods to create Linux Mint bootable USB on Windows, especially on Windows 10, which is now the most popular desktop operating syste.
Creating Linux Mint Bootable USB on Windows 10 is not hard at all. The first software recommendation is called UUByte LiteBoot. It is a leading program that's designed to handle all your needs for bootable USB thumb drive, including Windows, Linux and macOS.

Step 1: Once you have UUByte LiteBoot installed on your computer, download Linux Mint onto your Mac (you can download it from here).
Step 2: Insert a USB thumb drive into Windows 10 where UUByte LiteBoot being installed. Make sure your USB device is fully compatible with the hardware, you can empty it and then reformat it using the built-in utility from right-click optionsl.
Step 3: Open UUByte LiteBoot on Windows 10 and then select Linux Boot from the main menu. Now, import the Linux Mint ISO file you downloaded earlier. Before the burning process begins, make sure you have made a copy of all important files on that USB drive.
Step 4: Click Burn button to start burning Linux ISO to the target USB drive. It usually takes about 7 minutes to complete the task. Please be patient and you will see an alear on the screen when it is done.
Step 5: Now, you have a bootable Linux Mint USB. You should insert this drive into the computer and start installing Linux mint on it by changing the first boot device to USB during startup.
In short, if you are in searching for a reliable ISO burner to create bootable Linux Mint USB, then give UUByte LiteBoot a try. It is lightweight, fast, and reliable.
2. ISO to USB
ISO to USB is a free program that lets you burn ISO image file to a USB drive, including USB Pen drive, USB sticks and USB thum drive. It is lightweight and features a simple user interface. However, it lacks some important features, including the ability to create ISO archive from external drives.
First off, you can download ISO to USB from its website and then open it on your Windows 10 machine. When the main menu shows up, click Browse to locate the Linux Mint ISO file you downloaded earlier. Select the USB drive you inserted and then hit the Burn button. The tool will start burning the ISO file to USB drive. ISO to USB has a high success rate, so you won't have any issues here.
3. RMPrepUSB
RMPrepUSB is one of the most powerful software for creating Windows and Linux bootable USB drives. In reality, RMPrepUSB is not just about creating a bootable drive, as it can do a lot more. One such thing lies in the ability to format USB and run USB speed test. And there are much more options for selecting bootloader and file systems.
This program is completely free (no subscription plans), so you don't need to spend some extra cash on its advanced features. However, it is only for advanced users as there are two many advanced settings being involved.
Step 1: Download RMPrepUSB from here and then open it on your Windows 10 computer.
Step 2: Once you are done, insert a blank USB drive into Windows . From the main menu, you can see the USB drive name showing up at the top.
Step 3: Click Prepare Drive to initiate the burning process and click OK from the popup menu. If this the first time you are using RMPrepUSB, the tool will run a test. Once the test is complete, repeat the above steps.
Step 4: After the bootloader information was written to USB, then extract the ISO file of Linux Mint image and copy the folder to USB. Now, it becomes a bootable Linux Mint USB.
To verifiy the burning successful or not, the user can test the result with QEMU emulator that is embeded into the program in default. You can see the option on left sidebar. This is the same as UUByte Boot Pro.
Create Linux Mint Bootable USB on Mac: Terminal App
You can create a bootable USB for Linux Mint from a Mac environment. However, you can not do it on your own as you need a little help from some third-party software out there. If you do some googling, you should find tons of them, but many of them might not work for you. Don't worry, we made a list of the best programs for creating Linux Mint bootable USB.
If you don't want to install some third-party app on your computer, you can use the dd command in macOS Terminal. This is a cool tool that allows you to execute some commands in macOS. In this case, you can rely on Terminal to create a bootable USB for Linux Mint.
Step 1: Insert the USB drive into your Mac and then open Terminal (Applications folder > Utilities).

Step 2: Enter the following command to convert ISO file IMG file:
hdiutil convert -format UDRW -o img_file_output_path linux_mint_iso_file_path
Step 3: Find the USB drive number and unmount the disk, X is the drive number of inserted USB drive:
diskutil list
diskutil unmountDisk /dev/diskX
Step 4: When all preparations are completed, it is the time to write the converted IMG file to USB, which becomes bootable afterwards.
sudo dd if=/img_file_path of=/dev/rdiskN bs=1m
Step 5: Ignore warning message that pops up uppon completion and eject the USB drive. You can now use this bootable USB to install Linux Mint on any computer.
Linux Mint Bootable USB Not Working? Troubleshooting Guide
The success rate of creating bootable Linux Mint USB is pretty high with recommended tools we suggest above. However, some user may experience technical error during boot, such as disk error or no bootable device found. Here are a few useful tips to fix the problem.
Issue 1 : USB drive not detected
Answer: First, make sure the USB drive is installed. On Windows 7 and later version, the dirve will be installed automatically when the USB is plugged in. If failed, you have to download the USB driver and install it manually. On Mac, you can format the drive with Disk Utility app.

Issue 2: Black screen during installation
Answer: If you got a black screen during install, it means the burning process failed. Mostly because the free space is not enough on the drive. At least 4G free storage is required for installation. Also, check the ISO image is valid. If you tried two programs and failed, then it is highly possible that the ISO file is damged. You have to re-download the file again.
Issue 3 : Installation won't start
Make A Bootable Usb In Mac
Answer: This happens frequently on old hardware that does not support UEFI boot. You need to disable secure boot and swithc to legacy Boot in BIOS.
