These advanced steps are primarily for system administrators and others who are familiar with the command line. You don't need a bootable installer to install macOS, but it can be useful when you want to install on multiple computers without downloading the installer each time.
Jesus Vigo goes over the steps to create a bootable USB to install OS X 10.7-10.8 and OS X 10.5-10.6, as well as how to put multiple versions on the same USB. Step 2: Insert a USB drive. Once the installation is complete, insert the USB flash drive for making the bootable USB flash drive and open Etcher from the desktop shortcut menu or from the start menu. Step 3: Select a bootable image for Etcher. You will get the following user interface.
Download macOS
Download a macOS installer.* You can find the appropriate download link in the upgrade instructions for macOS Catalina, macOS Mojave, macOS High Sierra, macOS Sierra, and OS X El Capitan.
- If the macOS installer opens after downloading, quit it without continuing installation.
- macOS Sierra and El Capitan download as a disk image that contains an installer named InstallOS.pkg or InstallMacOSX.pkg. Run this installer before continuing.
- If downloading macOS Catalina, macOS Mojave, or macOS High Sierra for the purpose of creating a bootable installer, your Mac must be using macOS Sierra 10.12.5 or later, or El Capitan 10.11.6. Enterprise administrators, please download from Apple, not a locally hosted software-update server.
Then find the installer in your Applications folder as a single ”Install” file, such as Install macOS Catalina. Garageband vs ableton.
Use the 'createinstallmedia' command in Terminal
- Connect the USB flash drive or other volume you're using for the bootable installer. Make sure that it has at least 12GB of available storage and is formatted as Mac OS Extended.
- Open Terminal, which is in the Utilities folder of your Applications folder.
- Type or paste one of the following commands in Terminal. These assume that the installer is still in your Applications folder, and MyVolume is the name of the USB flash drive or other volume you're using. If it has a different name, replace
MyVolume
in these commands with the name of your volume.
Catalina:*
Mojave:*
High Sierra:*
Sierra:
El Capitan: - Press Return after typing the command.
- When prompted, type your administrator password and press Return again. Terminal doesn't show any characters as you type your password.
- When prompted, type
Y
to confirm that you want to erase the volume, then press Return. Terminal shows the progress as the bootable installer is created. - When Terminal says that it's done, the volume will have the same name as the installer you downloaded, such as Install macOS Mojave. You can now quit Terminal and eject the volume.
* If your Mac is using macOS Sierra or earlier, include the
--applicationpath
argument, similar to the way this argument is used in the commands for Sierra and El Capitan.Use the bootable installer
After creating the bootable installer, follow these steps to use it.
- Connect the bootable installer to a compatible Mac.
- Use Startup Manager or Startup Disk preferences to select the bootable installer as the startup disk, then start up from it. Your Mac will start up to macOS Recovery.
Learn about selecting a startup disk, including what to do if your Mac doesn't start up from it. - Choose your language, if prompted.
- A bootable installer doesn't download macOS from the Internet, but it does require the Internet to get information specific to your Mac model, such as firmware updates. If you need to connect to a Wi-Fi network, use the Wi-Fi menu in the menu bar.
- Select Install macOS (or Install OS X) from the Utilities window, then click Continue and follow the onscreen instructions.

This is how I configure USB flash drives so that I can install Windows from USB (WAY faster than using a disk).
11 Steps total
Step 1: Insert the USB drive into the computer, and make sure you can see it in Explorer.
Step 2: Launch a Command Prompt
All typing from this point will be done in this same window.
Step 3: Type: DISKPART {ENTER}
This will start DISKPART.exe, which we will use to get this drive formatted and bootable.
Step 4: Type: list disk {ENTER}
This will give you a list of installed disks, but they are labeled using the disk's number, not the name or drive letter (though it does show the size). If you are not sure which disk you want, open Disk Management, they are listed by all three identifiers there.
Attached is a pic of what this looks like on a Windows 7 machine.
WARNING:
If you select the wrong disk here, you will lose data, and possible overwrite your OS. Be sure you have the right disk selected.
If you select the wrong disk here, you will lose data, and possible overwrite your OS. Be sure you have the right disk selected.
Step 5: Type: select disk x {ENTER}
Where x = the disk number you want to format.
In the case of the example image it would be Disk 3, so to select the disk, type: select disk 3 {ENTER}
Remember to substitute the correct number for the disk you want to select.
Step 6: Type: clean {ENTER}
This will wipe the disk.
Step 7: Type: create partition primary {ENTER}
This will create a new partition on the drive.
Step 8: Type: select partition 1 {ENTER}
This will select the partition you just created.
Step 9: Type: active {ENTER}
This will set the partition to active (this is what allows a computer to boot from a drive).
Step 10: Type: FORMAT FS=FAT32 {ENTER}
Wait for it to get to 100% complete, this will format the drive using the Fat32 file system.
Step 11: Type ASSIGN {ENTER}
This will assign a drive letter to the drive in Explorer.
Now you should have a USB disk ready for the OS source files (you can either extract them directly from an ISO file, or just copy them from an install disk).
Using this, I was able to install Windows 7 x64 on an HP Elite 7000 in just under 7 minutes from first boot to desktop.

How To Boot Computer From Usb
- DatilPanda (w bold) Mar 10, 2010 at 07:03pmGood how-to, nice and easy to understand.
- SerranoIan Nolan Mar 11, 2010 at 03:58amGreat how to thanks for taking the time to write it up
- Pure CapsaicinJustin.Davison Mar 11, 2010 at 08:16amThanks for sharing, concisely written and easy to follow. Great Job.
- TabascoITMikeNJ Mar 16, 2010 at 09:34amThanks for the write-up. Makes the whole process simple and it is a valuable tool.
- JalapenoGadJeff Mar 19, 2010 at 08:30amLooks alot like this this one:
http://sbs.seandaniel.com/2009/10/how-to-make-usb-thumb-drive-bootable.htmlNot sure why Sean chooses NTFS in step #10 instead of FAT32. - HabaneroThereal_Joe Mar 19, 2010 at 01:19pmThis is a really common way to do this, it's much easier than using the HP drive prep tool, and cheaper (free) than some other tools). Just out of curiosity I ran a search for this, and there are numerous tutorials out there on how to do this (and most of them are very similar).I can't think of a good reason to use NTFS for this, if anything it would limit the usefulness of the tool.
- CayenneMark1950 Apr 13, 2010 at 03:21pmGood info!!
- Thai PepperJim H Apr 13, 2010 at 04:04pmI spent 4 hours last Friday searching the internet and trying different ways to do this. I guess I'll learn to search SpiceWorks first!! Thanks Joe.
- Thai Peppermanclncjj Apr 13, 2010 at 04:09pmFAT32 has File and disk size limitations that can cause issues so I use NTFS.
- DatilJohn2851 Apr 13, 2010 at 06:04pmFantastic Directions! One minor issue is that with Win XP diskpart will not see most removable disks so a Vista/Win 7 PC is needed. I know, minor but wanted to leave that comment for others before they spend too much time - honestly like I did when I first used diskpart - on trying WIn XP with this.
- AnaheimDon_OB Apr 15, 2010 at 02:39pmHas anyone had an issue with this working? I can see the USB drive, but it will not show up in DISKPART. I see the Disk # in Disk Management, but it's not showing up in DOS.Is this only a Win7 thing?Thoughts?
- HabaneroThereal_Joe Apr 15, 2010 at 03:35pmI've not seen this in Win7 (and I've done this very thing several times on Win7 machines). Has this drive been used to boot Linux in the past perhaps? Can you read/write to the drive in the OS outside of the command prompt? Can you address the drive from within the command prompt, but not using the diskpart utility (basically can you list the contents of the drive in a command prompt)?The only time I've ever had an issue where diskpart didn't see a flash drive, it was a drive that I had used previously to boot Knoppix.
- AnaheimSuhoy Apr 19, 2010 at 04:22pmAfter you did all instructions above, do following in order to make USB bootable:
Insert your Windows 7 DVD in the optical drive
Go back to command prompt and execute the following commands:D: and hit enter. Where “D” is your DVD drive letter.
CD BOOT and hit enter.
BOOTSECT.EXE/NT60 H: and hit enter. (Where “H” is your USB drive letter)
Copy Windows 7 DVD contents (including hidden) files to USB.I was able to boot and install Windows 7 from USB, it was much faster than from original DVD. - SonoraCEV May 4, 2010 at 09:07amWhat is the minimum size flash drive that should be used when doing this? Can it be done on a 2GB drive?
- PimientoSennan Jun 24, 2010 at 08:55pm@CEV Minimum is 4gb USB stick to fit the contents of the Win7 DVD.Another thing to note is that you cannot make a bootable Win7 64 installer USB with a 32 bit operating system.
