I have a MacBook Pro with OS X 10.10 and a Windows 7 Boot Camp install.
I just bought a 64 GB flash drive that I would like to put a bootable copy of Windows on, to reestablish the hard drive as OS X only, and figured it would be easiest to just clone the BOOTCAMP partition that I already have.
I formatted the USB to GUID/NTFS and used
dd to clone it:
dd if=/dev/rdisk0s3 of=/dev/rdisk2s2 bs=512 conv=noerror,sync
After 12 hours it finished, and does not work. Windows displays the partition as "RAW"
Anyone have any tips?
