Or extract the contents to the flash drive using p7zip as shown below.ħz x /path/to/Windows10.iso -o/media/username/usbdisk (requires p7zip-full) Rsync -avh -progress /media/username/Windows_DVD_Label/ /media/username/Windows\ 10/
#CREATE A BOOTABLE USB FOR WINDOWS 8 ON MAC ISO#
Mount the flash drive if needed and Windows ISO file and copy the contents (for example with rsync). Sudo mkexfatfs -n "Windows 10" /dev/sdb2 (requires exfat-fuse)ĭownload the uefi-ntfs.img file and double click to mount then copy the contents from UEFI_NTFS to the UEFI_BOOT partition which should then appear as shown below. Sudo mkexfatfs -n "Windows 10" /dev/sdb1 (requires exfat-fuse) Wimsplit /media/username/Windows_DVD_Label/sources/install.wim /media/username/Windows\ 10/sources/install.swm 3800įor a single partition format as shown below.
#CREATE A BOOTABLE USB FOR WINDOWS 8 ON MAC INSTALL#
Install wimtools/wimlib from your distribution’s package manager and use wimsplit to divide and transfer the install.wim file. Rsync -avh -progress -exclude=sources/install.wim /media/username/Windows_DVD_Label/ /media/username/Windows\ 10/
#CREATE A BOOTABLE USB FOR WINDOWS 8 ON MAC WINDOWS 10#
Now click on the flash drive and Windows 10 image file to mount both.Ĭopy all files except install.wim using rsync. When done, the install drive should appear as shown below: Sudo ms-sys -7 /dev/disk# (Windows 7/8/10 Master Boot Record) Sudo ms-sys -x /dev/disk#s# (exFAT NT6.0 Partition Boot Record) Sudo ms-sys -8 /dev/disk#s# (FAT32 NT6.0 Partition Boot Record) Install ms-sys utility linked below and write the appropriate partition boot record. 'p' - view partition table (Single partition #1 is assumed.) Set the partition active with fdisk (exclude the single quotes). Optional: for legacy/BIOS installation only. Move extracted files to the root of the flash drive if needed.
#CREATE A BOOTABLE USB FOR WINDOWS 8 ON MAC ARCHIVE#
Either mount the ISO file and copy everything via Finder or it may be faster and more reliable to use an archive utility such as Keka or p7zip (command line tool from Homebrew or MacPorts) to extract the contents of the image as shown below.ħz x /path/to/Windows.iso -o/Volumes/Windows\ 10 (p7zip example) Now copy the contents of the Windows ISO file to the flash drive. The UEFI_BOOT partition should appear as shown below: Hdiutil detach /Volumes/UEFI_NTFS (or eject the virtual disk) Then copy the contents from UEFI_NTFS to the UEFI_BOOT partition.Ĭp -R /Volumes/UEFI_NTFS/* /Volumes/UEFI_BOOT/ Hdiutil attach /path/to/uefi-ntfs.img (or double click the file) If using UEFI_NTFS download and mount the uefi-ntfs.img file. diskutil partitionDisk disk# 2 MBR "MS-DOS FAT12" "UEFI_BOOT" 1M ExFAT "Windows 10" R diskutil eraseDisk ExFAT "Windows 10" MBR disk#ī. Hdiutil detach disk# (or eject the virtual disk)įormat as exFAT with either a single partition (a) or two partitions if using UEFI_NTFS (b).Ī. Wimsplit /Volumes/Windows_DVD_Label/sources/install.wim /Volumes/WINDOWS\ 10/sources/install.swm 3800 Install wimlib with Homebrew or MacPorts and use wimsplit to divide and transfer the install.wim file. Now move the extracted files to the root of the flash drive. Rsync -avh -progress -exclude=sources/install.wim /Volumes/Windows_DVD_Label /Volumes/WINDOWS\ 10/ Hdiutil attach /Path/to/Windows.iso (or double click the file) Sudo diskutil eraseDisk FAT32 "WINDOWS 10" MBR disk#
Substitute the correct disk and Windows DVD path below. Open Terminal and use "diskutil list" to identify your flash drive (example disk3 below) then prepare using one option below (FAT32 or exFAT).įormat as FAT32 with a single partition, mount the Windows ISO and copy all files except install.wim with rsync. Legacy/BIOS booting is unaffected by filesystems and can boot directly.
If using exFAT you will likely need to boot the Windows installer from Clover or OpenCore or use the UEFI_NTFS bootloader from Rufus unless your firmware has native UEFI boot support for exFAT (see last section for details). NOTE: Recent releases of Windows 10 contain a file (install.wim) larger than 4GBs requiring it to either be split to accommodate the 4GB maximum file size limitation of FAT32 or the drive to be formatted as exFAT. Read carefully and download/install any required resources before attempting these procedures.ĭownload the Windows 10 ISO file and have an 8GB or larger USB flash drive ready.
#CREATE A BOOTABLE USB FOR WINDOWS 8 ON MAC HOW TO#
This procedure is intended as a replacement for " How to create a bootable Windows 10 USB in OS X using Terminal" as the technique described there is relevant to Linux hybrid ISO files (see references) but is unlikely to produce bootable Windows media. Windows 10 is described here but these instructions are valid for Windows 7/8. It can optionally be made BIOS bootable for legacy systems/installations as detailed below if desired. The resulting media will be bootable on any UEFI capable system which should be sufficient for the vast majority of computers in use today. This guide will detail the procedure to create a bootable Windows installer on a USB flash drive from either platform.
