[Editor’s note: This article is part of our series of articles on installing and upgrading to Lion (OS X 10.7). We also have a complete guide to installing and upgrading to Mountain Lion (OS X 10.8).]

Unlike previous versions of Mac OS X, Lion (OS X 10.7) doesn’t ship on a bootable disc—it’s available only as an installer app downloadable from the Mac App Store, and that installer doesn’t require a bootable installation disc. Indeed, this lack of physical media is perhaps the biggest complaint about Lion’s App Store-only distribution, as there are a good number of reasons you might want a bootable Lion installer, whether it be a DVD, a thumb drive, or an external hard drive.

For example, if you want to install Lion on multiple Macs, a bootable installer drive can be more convenient than downloading or copying the entire Lion installer to each computer. Also, if your Mac is experiencing problems, a bootable installer drive makes a handy emergency disk. (Lion features a new recovery mode (also called Lion Recovery), but not all installations of Lion get it—and if your Mac’s drive is itself having trouble, recovery mode may not even be available. Also, if you need to reinstall Lion, recovery mode requires you to download the entire 4GB Lion installer again.) Finally, a bootable installer drive makes it easier to install Lion over Leopard (assuming you have the license to do so).

1. Best option for any new macOS release on a Hack - especially a beta that's only been out a couple of days - is to do the upgrade first on a secondary SSD/HDD, or at least to make a bootable backup of your working install before updating the main drive.

Thankfully, it’s easy to create a bootable Lion-install volume from the Lion installer that you download from the Mac App Store; just follow the steps below.

Step 2 Create Bootable USB from macOS Install Image Click on Load DMG to import the macOS installation file into the application. Insert a USB (16G free space) and click on the 'Burn' button next to the appropriate media type.

Update: When this article was originally published, the Mac App Store version of Lion would not boot any Macs released in mid-2011 or later, as those models shipped with a newer version of Lion preinstalled. However, unlike with the CD- and DVD-based Mac OS X installers of old, Apple can—and does—update the Mac App Store version of the Lion installer. So if you create a bootable Lion-installer drive using the current version of the Lion installer—which, as of 2/10/2012, installs OS X 10.7.3—that drive will work with all current Lion-capable Macs. If your only Mac was released after Lion, so you can’t download the Lion installer from the Mac App Store, I’ve also provided instructions for creating a bootable Lion-install drive for newer Macs.

Part 1: For all types of media

1. Once you’ve purchased Lion, find the Lion installer on your Mac. It’s called Install Mac OS X Lion.app and it should have been downloaded to /Applications.
2. Right-click (or Control+click) the installer, and choose Show Package Contents from the resulting contextual menu.
3. In the folder that appears, open Contents, then open Shared Support; you’ll see a disk-image file called InstallESD.dmg.
4. Launch Disk Utility (in /Applications/Utilities).
5. Drag the InstallESD.dmg disk image into Disk Utility’s left-hand sidebar.

The next steps depend on whether you want to create a bootable hard drive or flash drive, or a bootable DVD. I recommend a hard drive or flash drive—a DVD will work, but it takes a long time to boot and install.

To create a bootable hard drive or flash drive

1. In Disk Utility, select InstallESD.dmg in the sidebar, and then click the Open button in the toolbar. This mounts the disk image’s volume in the Finder. The mounted volume is called Mac OS X Install ESD.
2. Click Mac OS X Install ESD in Disk Utility’s sidebar, then click the Restore button in the main part of the window.
3. Drag the Mac OS X Install ESD icon into the Source field on the right (if it isn’t already there).
4. Connect to your Mac the hard drive or flash drive you want to use for your bootable Lion installer. This drive must be at least 5GB in size (an 8GB flash drive works well), and it must be formatted with a GUID Partition Table. Follow Steps 1 through 4 in this slideshow to properly format the drive.
5. In Disk Utility, find this destination drive in the sidebar and then drag it into the Destination field on the right; if the destination drive has multiple partitions, just drag the partition you want to use as your bootable installer volume. Warning: The next step will erase the destination drive or partition, so make sure it doesn’t contain any valuable data.
6. Click Restore and, if prompted, enter an admin-level username and password. The restore procedure will take anywhere from five to 15 minutes, depending on your Mac and the speed of your drive.

Note: In versions of the Lion installer prior to 10.7.4, you didn’t need to first mount the InstallESD.dmg image—you could simply drag the image itself into the Source field. However, with the 10.7.4 installer, you must use the mounted Mac OS X Install ESD volume or you will get an error at the end of the restore procedure and the newly created bootable drive may not function properly.

Part 2b: To create a bootable DVD

1. In Disk Utility, select InstallESD.dmg in the sidebar

2. Click the Burn button in the toolbar.

3. When prompted, insert a blank DVD (a single-layer disc should work, although you can use a dual-layer disc instead), choose your burn options, and click Burn.

You can now boot any Lion-compatible Mac from this drive or DVD and install Lion. You can also use any of the Lion installer’s special recovery and restore features—in fact, when you boot from this drive or DVD, you’ll see the same Mac OS X Utilities screen you get when you boot into restore mode.

Note: As explained in our main Lion-installation article, if you leave the Lion installer in its default location (in /Applications) and use it to install Lion on your Mac’s startup drive, the installer will be automatically deleted after the installation finishes. So if you plan to use that installer on other Macs, or to create a bootable disc or drive as explained here, be sure to copy the installer to another drive—or at least move it out of the Applications folder—before you install. If you don’t, you’ll have to re-download the entire thing from the Mac App Store.

If you’ve already installed Lion—so it’s too late to move the installer—you’ve may find that the Mac App Store claims that Lion is already installed and prevents you from downloading it again. As I explained in our main Lion-installation article, you should be able to force a re-download using one of the following three tricks: First, Option+click the Buy App button in the Mac App Store. If that doesn’t work, switch to the Mac App Store’s main page and then Option+click the Purchases button in the toolbar. If that doesn’t work, quit the Mac App Store app and then hold down the Option key while launching the Mac App Store again. One of these three procedures should get rid of the “Installed” status for Lion and let you download it. Update: Apple appears to have recently made this process easier: If you previously purchased Lion from the Mac App Store, the button next to Lion in the Store should simply say Download—click it to re-download the installer.

Updated 7/20/2011, 10am, to add note about moving the Lion installer package to prevent it from being deleted.

Updated 7/22/2011, 11:10am, to add instructions for forcing a re-download of the Lion installer, if necessary.

Updated 8/8/2011, 9:19am, with additional information about thumb-drive capacity and drive format.

Updated 8/19/2011, 2pm, to clarify compatibility.

Updated 2/10/2012, 12pm, with information about compatibility when using the latest Lion installer, and to note easier re-downloading of Lion installer.

Updated 6/27/2012, 9pm, to add note about Disk Utility error message introduced with the 10.7.4 installer, and 6/29/2012, 8:20am, to update instructions so they work when creating a drive using the 10.7.4 installer.

macOS Big Sur is coming in the fall of 2020, so this is a good time to learn how to create a macOS Big Sur bootable USB so you can install it on multiple Macs. This article shows you how to create the macOS installer on Windows 10 using UUByte DMG Editor, which is a professional and cross-platform disk authoring tool.

How to Download macOS Big Sur DMG File

Let's briefly look at how to download macOS Big Sur DMG file. Of course, there are several third-party sources that are now offering the macOS Big Sur beta version as DMG but not all of them are trustworthy. For that reason, we recommend that you sign up for the Apple Beta Software Program here and proceed to register an Apple device so you can get access to download the OS profile and Big Sur Install app. Obviously, you can't register your Windows 10 computer so you will need a Mac computer to acquire the app.

If you don't have a Mac at hand, then you can directly download macOS Big DMG file via (link 1 or link2). The download might be a little slow as it is hosted on a third-party website. It could be much faster if it were hosted on Apple server or Google Drive.

Troubleshooting when Burning macOS DMG to USB

Make Bootable Usb From Dvd

Occasionally, you may run into some errors while preparing to burn macOS DMG to a USB drive. Here is a list of the most common problems and how to fix them:

USB Drive Not Detected: If your USB stick isn't being detected, it's a system problem or an issue with the drive itself. Make sure USB drive is installed on the PC. You can also try another drive to see if it works, or switch it to a different port.

Insufficient Space: This is another common problem that's easily rectified. All you need to do is use a different flash drive with additional capacity. macOS Big Sur disk image files usually require about 16GB capacity on the USB drive.

Corrupted DMG File: In this case, you can either try to repair the corrupted file if you have the knowledge to do so, or go ahead and download the file again from Apple's servers via the Beta Program. This issue sometimes occurs when you get disk images from third-party websites, which is why we recommend the Beta Program.

USB Installer Not Working: In rare cases, the burning process might have had an error. If so, you can use UUByte DMG Editor to burn the DMG file again to the USB drive. However, make sure that there's no issue with the DMG file itself because the editor has a high burning accuracy rate and such problems should not occur frequently.

Conclusion

Once you have macOS Big Sur installer USB ready, you can insert it into any Mac and run the program to install Apple's latest desktop operating system. Big Sur is officially coming in the fall and has a ton of updated features on nearly all fronts, including the OS interface, Safari, Siri, Messages for desktop, etc. But you should also know that since the currently available DMG is only a public beta tester version, it is bound to have bugs and other issues. If you're on the beta program, you can use the feedback app to let Apple know what the issue is. Unfortunately, that also means that there's nothing you can do about it if you're not on the beta program.
