A dual boot Windows PC containing Windows 10 and macOS is not that hard to create. Fondly called a Hackintosh, such a setup allows you to enjoy the best of both operating systems on a single computer, hence the phrase dual boot. One of the biggest reasons that people want to create Hackintoshes is that they have the freedom to choose from two different desktop app sources. On a dual boot, you can enjoy popular Windows applications from the Microsoft Store as well as the best nuggets from the Mac App Store - all on a single computer.

The easiest way to do this is to get a Windows 10 PC and then partition the drive so you can install macOS on that partition. Each OS requires its own partition or its own drive. In this article, we'll show you how to create a partition and install the Mac operating system alongside the existing copy of Windows 10 on your PC.

Currently this tutorial is applied to macOS Mojave and High Serria, Mac OS X Serria, EI Capitan and Yosemite

Preparations before Making a Dual Bootable (Win 10 & macOS) PC

There are a few things to keep in mind at this point. First, you don't need a secondary drive to do this. The shared drive method of dual booting will work just fine as long as you have enough space on the disk for an additional partition for your copy of macOS.

The second requirement is that the disk needS to be already partitioned as GUID Partition Table, or GPT. Otherwise, you will need to first delete Windows, install macOS after formatting the disk, and then install Windows 10 at the end. The reason Windows 10 comes last is that certain errors might occur if you try installing Windows first.

P.S if the current OS is not Windows 10, then you have to create a bootable Windows 10 USB and install it on the computer first.

Third, you will need to create a macOS USB installer before attempting the dual boot. You can do this on a Mac by getting the installation files via the App Store and then burning the DMG file inside to a USB drive using Disk Utility app.

Dual Boot Windows 10 and Mac OS on PC without Erasing Windows

To start off, you will need a disk partition utility to help you allocate the required space. A free tool like MiniTool Partition Wizard Free Edition is more than adequate. Once you have the software, follow the steps shown below.

Step 1: Launch MiniTool Partition Wizard and look for the EFI system partition. If not EFI partion found, then create a new partition with GPT.

Step 2: If the EFI partition is less than 200MB, you will need to expand it by taking space from the partition before or after it. This is usually the case when the disk is formatted for Windows, which only allocates 100MB for the EFI partition. You can right-click on the partition to resize it.

Step 3: Now right-click on the new partition and select Split to create a new partition for the macOS installation. The size can be specified on this page. Click OK to apply the changes.

Step 4: The next step is to format this partition. To do this, right-click on the macOS partition and select Format. Set the file system to FAT32 and confirm by clicking OK.

Step 5: You will now need to boot your PC from the macOS USB installer. In Windows, you can do this by hitting the F2 during the startup process. This takes you to the BIOS Setup Utility, where you can change the boot priority so the computer boots from your macOS USB installer instead of the existing Windows files. Once the PC boots up from the installer, open Disk Utility from Applications >Utilities. Select the partition inside Disk Utility and hit Erase. Set the format to APFS (macOS High Serria and Mojave) or Mac OS Extended (journaled) for OS X 10.12 and below. After that, click the Erase button to start the partition process.

Step 6: The next thing is to merge the EFI folders from Windows EFI boot drive and the USB installer, and for this, you can use an EFI mounter like Clover Configurator. The purpose of this step is so that your macOS can boot from the partition instead of from the USB installer.

Step 7: Restart Windows 10 PC and boot from macOS install USB. Follow the prompt to start the macOS installation process.

Step 8: There's still one more step required to make sure the dual-booting works, and that is to modify one single file so that both partitions are visible as boot sources. This is important because, otherwise, you will have to boot to macOS from the installer each time, which is a complex and unnecessary task. The steps in the image below show you how it's done:

Step 9 : The final step, which is optional, will make your computer boot into Clover instead of Windows. This allows you to choose which OS to boot into, and it's a very convenient thing to set up. You can also do this when your drive name fails to show up despite following Step 6. See the steps shown in the image below.

The process is now complete. When you restart your PC, you will see two boot options in the Clover interface - one for Windows and one for macOS. Select the OS you want to work on and resume the boot process. You will need to restart to access the other OS, which is a minor inconvenience, but that's a trade-off you're going to have to be willing to make if you want a dual boot computer with both Windows 10 and macOS.

Another way is to use separate drives so each OS has its own drive and own EFI system partition. This can be done when your original Windows drive is not formatted for GPT. If it is, then you can follow the steps described in this article to do a dual-boot on a shared drive.

macOS Catalina is the latest release in the macOS series. With its launch come plenty of user-friendly features, including the ability to use your iPad as an external screen, and the ability to regulate app usage through the amount of screen time it takes. Perhaps the most notable change is the replacement of the iTunes app with three different apps: Apple Podcast, Apple Music, and Apple TV.

Speaking of macOS Catalina, it is almost a year since Apple declared its intentions to make it easy for developers to move iOS apps over to Mac. The company fulfilled the promise with the release of macOS Catalina, which allows users to run iPad apps on their Macs.

macOS Catalina Public Beta

If you are excited about the launch of Catalina and can’t wait to try it, you can join Apple’s Beta Software Program. This way, you get to test the cool features of macOS Catalina before Apple ships it this fall. Unfortunately, Catalina is only available through a beta version.

Some people may be hesitant to try the beta version of Catalina because they fear it might cause inconvenience and mess up their workflow. The good news is that updating to the new version of macOS doesn’t have to be an all-or-nothing affair. You can still run Catalina and Mojave together. In this article, we will show you how to run the two versions of macOS on a Mac.

But First, Why Dual Booting Is a Good Idea?

There are many reasons you might want to run two versions of macOS on a Mac, but here are the key ones:

  • First, you have to use your Mac to carry out your other daily activities, but you still want to try the new OS. With dual booting, you can test the new macOS version without interfering with your workflow. If it turns out to be stable, you can get rid of Mojave without unnecessary pauses.
  • Updating to the latest operating system can be a challenge if you have legacy apps that are not compatible with it. So, dual-booting is a smart idea if you need to run those apps.
  • Apple has only provided a beta version, so you don’t have another choice.

While Catalina brings lots of improvements, its hardware requirements are still the same as for Mojave. So, any Mac built after 2012 will support the new macOS version. But if you are curious, here are the Mac models that are compatible with the new operating system:

  • MacBook Air 2012 or later
  • MacBook 2015 or later
  • MacBook Pro 2012 or later
  • MacBook Pro 2013 or later
  • iMac 2012 or later
  • iMac Pro 2017 or later
  • Mac Mini 2012 or later

How to Run Catalina and Mojave Side-by-Side?

If your Mac is compatible with macOS Catalina, follow the steps below to dual boot Catalina and Mojave on your Mac:

Step 1: Initial Preparations

Back Up Your System

Once installed, macOS Catalina will have access to all the files on your Mac, so back up all your important files just in case anything goes wrong. Preferably, create a backup of your Mac before you even download the latest OS.

Clean Your Drive

The other thing you need to do is to create space for the new macOS version. To do that, delete all the junk in your system. The more space you have, the better. Start with removing unnecessary apps, files, and folders. You may also need to transfer your photo library into an external disk.

Doing all these can be time-consuming, and there is also the risk of deleting crucial system files. Taking this into account, we recommend the Mac repair app tool for this purpose.

Consider Installing macOS Catalina on an External Hard Drive

If wiping up your system sounds too risky, then you can try installing the new version of macOS on an external hard drive.

Step 2: Create a New Volume

Dual Boot Mojave And Catalina 2020

For it to run, macOS Catalina will require its own partition on your hard drive. If you are running Mojave or High Sierra, this process is straightforward, as your computer will use the new Apple File System. If your startup disk is not formatted as APFS, it is much better to install macOS Catalina via an external hard drive. With that said, let’s go ahead and create a new partition for macOS Catalina:

  1. Open the Disk Utility program by going to Finder > Applications > Utilities, then choose Disk Utility.
  2. Once the Disk Utility opens, click on the drop-down menu next to the View button and select Show All Devices.
  3. Choose the hard drive you want to partition, and then click on the plus (+) icon in the toolbar to create a new partition.
  4. Give your new partition a name.
  5. You also need to set the storage limit for this partition. Allocate about 25GB – 100GB for it, and then format the partition as APFS.
  6. After that, click Apply to save the changes.

Now, you have a new volume ready to install the beta version of macOS Catalina.

Step 3: Download and Install macOS Catalina

Now that you have a new partition, your next step is to download and install macOS Catalina on the newly created volume. To do that, follow the steps below:

  1. To download Catalina, you first need to enroll for Apple’s Beta Software Program. You do so by signing into the program with your Apple ID.
  2. Once you have done that, download the macOS Public Beta Access Utility.
  3. Wait for the OS to download. When the download starts, you will be prompted to select a location for the installation. Select the volume you just created above.
  4. When the download finishes, install the new OS.

Step 4: Dual Boot Catalina Beta and Mojave

Once you have installed macOS Catalina on your Mac, the remaining task is to choose the version of macOS to boot into. Here is how to do it:

  1. As you restart your Mac, press and hold down the Option Key, and then choose either Mojave or Catalina.
  2. Before you restart or shut down your computer, head to the Apple menu, and then select System Preferences. After that, choose Startup Disk and pick the OS you want to boot into next time.
