In case i already insert a new disk and it's /dev/sdc so...

then select your disk, who want to be ur LVM disk it's (sd?)

create disk partition in case i use (sda) disk

~: sudo fdisk /dev/sdb

inside fdisk /dev/sda

: m (to help)
: n (to create new partition)
: p (to create as primary disk)
: i press enter at this section (Partition number), (First Sector), (Last Sector)
: t (to change Linux type to LVM)
: Hex code type (8) for LVM 
: w (to write your new partition)
