I'm trying to create a bootable USB for Windows using Disk Utility on OS X 10.8.4. Downloaded CentOS 6 for 32-bit and tried to use Disk Utility to create a bootable USB drive. This method failed with one of the two following errors:
"Could not restore - Invalid argument"
"Could not restore - error 254"
None of these solutions worked:
- Convert the .iso to .dmg
- Change permissions to rwx+ugo on image
- Download image from another mirror
- Use "minimal" image vs "full"
- Change USB stick
- Restore the "/Volumes" image (i.e. dragging from Desktop, not left panel of DiskUtility)
UNetbootin appears to burn the image to the USB, but testing on a Windows box shows that the disk image is missing.
