Real Mac or Hackintosh? If Hackintosh, you need to install the bootloader to the cloned drive after cloning.
Is this what you mean by installing bootloader (These are directions from chameleon)
"
Suppose that your installation is on /dev/disk0s2
- Install boot0 to the MBR:
sudo fdisk -f boot0 -u -y /dev/rdisk0
- Install boot1h to the partition's bootsector:
sudo dd if=boot1h of=/dev/rdisk0s2
- Install boot to the partition's root directory:
sudo cp boot /

I would prefer to use boot camp if thats possible? I want to clone partition for a test install.
