With all due respect for the Author (the article is seemingly a very nice one) there is the everstanding confusion between disk and partition/volume.
I had hoped that - particularly for something intended to explain things - I would have had not to read "format a disk".
Just in case, a disk is partitioned (in either MBR or GPT "style"), and the partition(s) or volume(s) on it thus created are later formatted with a given file system.
You can certainly format a whole disk. I did it, the disk in my laptop doesn't have a partition table at all. The whole disk is one big encrypted filesystem. The laptop boots off of an external USB stick.
Sure you can, but that disk won't be bootable in UEFI (it may still be in BIOS). The article is about UEFI booting, with parted he checks the partitioning "style", not the actual formatting.
>See that Partition table: msdos? This is an MBR/MS-DOS formatted disk. If it was GPT-formatted, that would say gpt.
