I’m new to Linux btw. I installed Artix Linux on my pc then decide to switch to using arch instead. I used fdisk to clear my nvme0n1 of all its partitions from artix, then did a full fresh reinstall of the usb iso. Now when I boot into the usb it separates my usb and my nvme into different sections instead of having my nvme be sda. When I try to do cfdisk /dev/nvme0n1 and partition it, it won’t work.

Any help?
