That is pretty straightforward to do, using the graphical parted facility once the livecd is running. When selecting to write a partition table you just select the GPT option from the pull down menu that is presented. Then you can choose the new partitions and complete the partitioning before starting. My UEFI system was done this way and works well. -- mike c
