Above is my “fdisk -l”, my current problem is when I go and try to do “pvcreate /dev/sda2” it gives me “Can’t open /dev/sda2 exclusively. Mounted filesystem?” and I have been searching google for a while now trying to find a way to fix this. There is defiantly things I tried from google but none of them ended up working.

Answer
You’re trying to initialize a partition for use by LVM that’s currently used by swap.
You should rather run
pvcreate /dev/sda3
