Changing label type in Arch Linux cfdisk

Question

I'm trying to install Arch Linux on a disk which was previously partitioned. The Disklabel type is automatically set to gpt. I need to change it to dos. How can I do it?

Answer 1

I've never actually used cfdisk, but I can tell you how to do it with fdisk.

1. Run fdisk -l
2. You should get all of your storage devices.
3. Find the one you want to partition.
4. It should be something like /dev/nvme0n1 or /dev/sda but your knowledge may vary.
5. Once you find it run fdisk <name of drive>. E.x. /fdsik /dev/sda
6. You should now see something like this

Welcome to fdisk (util-linux 2.35.2).

Changes will remain in memory only, until you decide to write them.

Be careful before using the write command.

Command (m for help): 

Typing m reveals:

o create a new empty DOS partition table

Notes:

• Know that changing the labels will delete everything.

• Don't forget to run w before exiting to write table to disk.

• Check the Arch Wiki for more information.
