I tried to list the partitions on a Windows machine using an Ubuntu Live CD and I got this error when trying to use fdisk to list the partitions.

[email protected]:~$ sudo fdisk -l /dev/sda
 
WARNING: GPT (GUID Partition Table) detected on '/dev/sda'! The util fdisk doesn't support GPT. Use GNU Parted.

Fdisk will not let you list partitions on a GPT partition table. Instead, use GNU parted. This command will list all partitions in a GPT partition table on a Windows machine.

This will list it as machine parseable output.
