Partition table

If the hard disk we are partitioning has already a partition table, we must delete it and create a new one

If we are installing from terminal, we will be in tty1, accesible with Ctr + Alt + F1

1) Delete LVM

Go to tty2 (Ctrl + Alt + F2)

#: lvdisplay
#: lvremove /dev/vg00/lvvar
#: lvremove /dev/vg01/lvvirt
#: lvremove /dev/vg02/lvsrv

2) Delete RAID

We can delete those from the installer (Ctrl + Alt + F1) Refresh the changes we just made in LVM: Go back -> Partition disks and then Configure software RAID -> Delete MD device ...
