I am trying to make a bootable USB with the dd command since Boot Camp does not work. If I execute this command:
sudo dd if=Win10.iso of=/dev/disk1 bs=1m
I get a disk formatted as Universal Disk Format with a GUID partition scheme making it unbootable. The way I changed it to Master Boot Record (FDisk) partition scheme was to erase the failed USB contents, change it to FDisk, and run the dd command with disk1s1 instead of disk1 (disk1s1 was the identifier of the only partition on the USB).
What that has done was made an unmounted partition called disk1s1, formatted in FAT and with the FDisk partition scheme, but it is unmountable and I cannot boot from it. When I try mounting it, nothing happens, and the terminal command output is
Volume on disk1s1 failed to mount. I cannot repair disk and Verify disk says
Invalid BS_jmpBoot in boot block: 000000
As far as I can remember, Ubuntu's bootable USB showed similar behavior with the unmountable disk, but it was detectable by rEFInd.
The error message I get in VirtualBox is:
VD: error VERR_NOT_SUPPORTED opening image file '/Users/username/RawWinDisk.vmdk' (VERR_NOT_SUPPORTED). VD: error VERR_NOT_SUPPORTED opening image file '/Users/username/RawWinDisk.vmdk' (VERR_NOT_SUPPORTED). Failed to open image '/Users/username/RawWinDisk.vmdk' in read-write mode (VERR_NOT_SUPPORTED). Failed to attach driver below us! Not supported. (VERR_NOT_SUPPORTED). AHCI: Failed to attach drive to Port0 (VERR_NOT_SUPPORTED).
I am using OS X 10.9.5 (Mavericks), and I have a 13-inch, Mid 2012 MBP
