Windows 7 ISO to Bootable USB on MacThe downloadable Windows 7 ISO's from Microsoft are no longer available unless you have a retail INSTALL-KEY. Probably due to the push to Windows 10.
I found myself in a position with a Windows 7 ISO OEM and no Windows 7 DVD.
How do you burn a Windows 7 ISO to a Bootable USB on Mac?
Despite various other attempts, this is the only instruction set that worked.
START WITH FRESH USB STICK
- -insert usb-stick.
- -open DISK-UTILITY.
- -partition with 1 partition.
- -format at it as raw disk.
- -select the option to have a GPT BOOT.
- -apply changes.
COPY ISO TO USB STICK
- -open terminal.
- -type: diskutil list
- -it should output the disks, their device-names and the partitions.
- -type: diskutil unmountDisk /dev/disk1 (substitute for your disk number here)
- -type: sudo dd if=/path/to/downloaded.img of=/dev/rdisk1 bs=1m
- -wait about 20~30 minutes.
- -diskutil eject /dev/disk1 (substitute for your disk number here)
NOTES:
- -you do not have to format the usb stick with a filesystem (ntfs, fat, hfs+, etc). The ISO already has the filesystem in it.
- -if terminal is open, you can check the progress by hitting CTRL+t.
