The Issue: Upon successful installation, boot from hard drive results in this: Loading Operating System … boot0: GPT boot0: test boot0: test boot0: GPT boot0: test boot0: test boot0: error The Actual Problem: With disk drives getting larger and larger manufacturers have had to change the default block size from 512 bytes to 4,096 bytes. These new drives are known as "Advanced Format" or 4K drives. Initially this was only seen on drives larger than 1 TB but will soon be on all drives. As part of this change there is an issue with OS X writing the boot helper code to these drives when booted from the drive. Because of this they require a workaround to boot on their own. NOTE: THIS GUIDE IS FOR LEGACY BOOTLOADERS ONLY- DO NOT USE WITH CLOVER. Solution 1: Use UniBeast Pros: Easy- OS X Only Cons: Requires use of the Terminal and UniBeast drive. How To Do it: 1.
