Use Dd Mac To Write Dmg To Partition Windows 7
If Mac OS X doesn't recognize the flash drive, it prompts you to format it and the Disk Utility app opens. Select 'ExFAT' in the Format menu of the Partition tab only if you want to use the flash drive on a Windows PC. Otherwise select 'Mac OS Extended (Journaled)' if you plan to use.

Third, use dd with an appropriate buffer size to copy over the whole block image, including partition table and boot sector. Note that it is extremely important on some hardware to use a large block size; you can expect a 20x speedup. To create a bootable USB drive from a DMG file on Windows, you will need to have the right utility. That's because DMG is not native on Windows. It is the Mac equivalent of an ISO file that has been in use since Apple transitioned from the IMG format with Mac OS X. A DMG file, like ISO, can be used to install macOS operating system or Mac apps. Dd copies the entire partition including unused space and no compression and is difficult to restore if just cloning the BOOTCAMP partition. You cannot make a DMG image of the BOOTCAMP partition as macOS by default cannot create an NTFS DMG and does not write to NTFS formatted media, use Winclone. – user3439894 Sep 7 at 16:41.

DMG images are typically a kind of Universal Disk Image Format (UDIF), although there are others, namely NDIF and SPARSE. Although the.dmg file extension is usually used, they can also sometimes have an.img extension, or in some cases no extension at all. Write the ISO image to the USB drive like this: sudo dd bs=4M if=image.iso of=/dev/sdX%% sync Replace “X” with the appropriate letter. For example “/dev/sdb”. Be sure to use the drive directly and not a partition within the drive. For example, don’t use “/dev/sdb1”. This will probably take a little while to complete.

Disk Utility User Guide
You can restore a disk image to a disk. To do this, you first need to erase the disk. If the disk image has multiple partitions, you must restore each partition individually.
Restore a disk image with a single volume to a disk
In the Disk Utility app on your Mac, select the volume that you want to restore in the sidebar, then click the Restore button .
This is the volume that is erased and becomes the exact copy.
Click the Restore pop-up menu, then choose the volume you want to copy.
If you’re restoring from a disk image, click the Image button, then navigate to that disk image.
Click Restore.
Restore a disk image with multiple volumes to a disk
To restore a disk image with multiple volumes to a disk, you must partition the destination disk, then restore each volume individually.
In the Finder on your Mac, double-click the disk image to open it.
The disk image’s volumes appear as disks in the Finder.
In the Disk Utility app, select the disk in the sidebar, click the Partition button , then partition the destination disk.
The destination disk must have as many partitions as the disk image, and each of the disk’s partitions must be at least as large as the corresponding partition in the disk image. See Partition a physical disk in Disk Utility on Mac.
In the sidebar, select the volume that you want to restore, then click the Restore button .
This is the volume that is erased and becomes the exact copy.
Do one of the following:
Restore from a volume: Click the “Restore from” pop-up menu, then choose the volume you want to copy.
Restore from a disk image: Click Image, choose the disk image you want to copy, then click Open.
Click Restore.
Repeat steps 3–5 for each remaining partition.

The instructions below are specific to the Disk Utility program available on the Mac OSX Operating System on the Macintosh computers in IT Computer Classrooms. Even if your computer has a different version of Mac OS X, these instructions should provide a general guide for completing this process. Refer to the documentation provided with your Mac operating system software if you need more specific information.
Burn a DMG or ISO File to Disk
After you have downloaded a program's installation file (*.dmg format for a Mac-compatible program, *.iso format for a Windows-compatible program) to a Macintosh computer's hard drive, you can burn this *.dmg or *.iso file to a blank CD or DVD. You can use this disk to install the program on another computer, or have a backup installation disk in case you need to reinstall the program in the future. You can use a Mac to burn an *.iso file to a disk, and the resulting installation disk will run properly on a Windows computer.
Note: For .dmg or .iso files that are larger than 4.7 GB, you will need to use dual layer DVD. See About Recordable Media Types for more information about different types of recordable DVDs.
To burn a DMG or ISO File to disk:
Start Applications > Utilities > Disk Utility. The Disk Utility window will open. The Mac's available drives (e.g., hard drive partitions, CD/DVD drive) will be listed by name in the left pane.
Insert a blank CD or DVD disc into the Mac CD/DVD drive. Note: If the CD is blank, the You inserted a blank CD pop-up window will appear. Select Action > Open Disk Utility, then click OK. The Disk Utility (a.k.a. SuperDrive) window will reappear.
Drag the *.dmg or *.iso file from a Finder window or the desktop to the Disk Utility window, and drop it in the left pane in the empty area below the Mac drive names. The *.dmg or *.iso file name will display in the left pane of the Disk Utility.
Note: You can drag and drop multiple files to the Disk Utility.Select the *.dmg or *.iso name in the left pane of the Disk Utility, then click Burn (top left). The Burn Disc In: window will open and display the destination (your blank CD/DVD) for your file.
In the Burn Disc In: window, click Burn. The Disk Utility Progress window will open and the burning process will begin.
When the burning is complete, the disk is ejected from the drive and the Disk Utility Progress window displays a message that the image burned successfully. Click OK. The Disk Utility Progress window will close.
You can now close the Disk Utility and use your installation disk.
About Recordable Media Types
There are two types of recordable CDs and DVDs: CDs and DVDs labeled 'R' can only be recorded on once, while those labeled 'RW' allow you to write data to them once and then add more files later. You can also erase the data on CD-RW or DVD-RW disks entirely and re-use them, which you can't do with DVD/CD-Rs. You can use either kind in IT Computer Classrooms.
