Previously, Linux used the same GUID for the data partitions as Windows
(Basic data partition: EBD0A0A2-B9E5-4433-87C0-68B6B72699C7).
This created problems when dual-booting Linux and Windows in UEFI-GPT
Setup, so a new GUID (Linux filesystem data:
0FC63DAF-8483-4772-8E79-3D69D8477DE4) was defined jointly by GPT fdisk
and GNU Parted developers.
