Remove a GUID Partition Table (GPT) in Linux

My initial though was to use fdisk. However, fdisk does not understand GUID Partition Tables and therefore cannot remove such tables. The other tool that does understand GPT is a tool called “parted”.

So to replace the GPT table with msdos, I did:

parted /dev/sdc
mklabel msdos
quit
