Clover Boot Disk – Create macOS High Sierra bootable USB from Windows

Clover Boot Disk includes tools and partition images to help you create macOS High Sierra bootable USB from Windows in just a few clicks.


As instructed here, I have successfully created a macOS High Sierra bootable USB from macOS. Then I thought I should back up the partition of the macOS installer and share it with everyone who wants to use it from Windows.

I have created two partition image files, the first is Clover Bootloader and the second one is macOS installer.  The only thing you need to do is use Partition Image Mapper to use these two files as two real partitions on your USB.

Clover Boot Disk is the name after you have a USB bootable via Clover. I have not tested on the official MAC. It works for Hackintosh machines. Clover Boot Disk supports both Legacy BIOS and UEFI modes, because Clover supports both modes.

This article does not instruct you to use Clover Bootloader, as well as install macOS. You need to study for your own.

Clover Boot Disk


Clover Boot Disk includes 3 files:

  • Clover.img
    This is the partition image of Clover Bootloader. It allows you to boot into Clover in both UEFI and Legacy modes.
  • OSX_10.13.2_Installer.hfs
    This is a partition image of the macOS High Sierra installer.
  • PartIMGMapper.exe
    Partition Image Mapper helps you to use the two partition images above as two real partitions on the USB.

Download all files at:

How to?

Once downloaded, we will use the Partition Image Mapper as the steps below. This tool is part of AIO Boot.

  1. Format the USB drive to NTFS. Because FAT32 can not contain files larger than 4GB. Skip this step if you are using NTFS.
  2. Create the folder /AIO/File/PartIMG on the USB drive and copy the Clover.img and OSX_10.13.2_Installer.hfs files to this folder.
  3. Run PartIMGMapper.exe
    Create macOS Sierra bootable USB from Windows

    1. Select Clover.img in row 1.
    2. Select OSX_10.13.2_Installer.hfs in row 2. You need to select HFS/HFS+ under Type.
    3. Select the Clover box under Install MBR if you want to boot Clover in Legacy mode.
  4. Click MAP button.
  5. The tool will back up the partition table information for later restoration. The file has .MBR extension in the same directory as PartIMGMapper.exe.
  6. Once used, run PartIMGMapper.exe, click UNMAP and select the previously backed up MBR file. All data and partitions will be restored as before.

PartIMG Mapper

PartIMG Mapper has the same features as Partition Image Mapper, but it runs directly on Grub2 and Grub4dos without Windows.

Clover do not allow overlapping partitions. This means that the beginning of this partition is part of another partition. To fix this, just delete the partition where you are putting the Clover.img and OSX_10.13.2_Installer.hfs files above.

Clover Boot Disk Creator

Some users have reported that they experience an error when using Partition Image Mapper. If you also encounter errors, you can Clover Boot Disk Creator tool. However, your USB will lose all data, only use this tool if the Partition Image Mapper does not work.

Clover Boot Disk Creator

  1. Clover: Select the Clover.img file.
  2. OSX: Selects the OSX_10.13.2_Installer.hfs file.
  3. Target Disk: Select your USB.
  4. Click OK.

Good luck!

    Im getting an unspecified error when selecting a file, what can I do?

    • Hi, try defragmenting the file first.

      • lemonadez

        Cannot defrag the file on USB 8GB. Because the size is too big.

        • Hi, try re-formatting the USB and copying the files.

          • lemonadez

            Did reformat USB twice and then try exFat too. but everytime i copy the files over usb it become fragmented. anyway i manage to do it on 16GB. but yea it didnt support AMD Phenom II 560 Cpu. I had Snow Lion on it before. but for now i will just use elementary os.

            For me, 10.13.2 shows that the osinstall is missing and 10.12.6 doesn’t even boot

          • Gustavo

            I downloaded the 10.12.6, you need to make sure that your system has compatibility also.
