Hi

"GPT, the GUID Partition Table, is an alternate disk partition table
scheme that solves two problems associated with the MBR (Master boot
Record) partition table. It allows the configuration of more than four
primary partitions, the maximum supported by MBR, and also supports disk
partitions of more than 2 TB. So GPT will be the default partition table
scheme on Fedora 16"
