Linux how to copy GPT partition table with dd

The old MBR 512 bytes partition table is no longer valid if you are using GPT. 

To copy a GPT table with dd to another disk do it like so:

Below sda is the source disk and destination disk is sdb (change to meet your needs).

dd if=/dev/sda of=/dev/sdb bs=1536 count=1

You can also use dd to backup your partition table like normal but with the bs of 1536

dd if=/dev/sda of=/root/sda-gpt-table-backup.img bs=1536 count=1
