install LVM dual boot with Windows

Create a /boot partition as ext4 with a size of 256-512MB and another partition you want to use for lvm, using for example gparted. Then manually set it up for lvm (assuming the partition you want to use for lvm is number 5):

sudo pvcreate /dev/sda5
sudo vgcreate myvg /dev/sda5
sudo lvcreate -n swap -L 400m myvg
sudo lvcreate -n home -L 60g myvg
sudo lvcreate -n root -l 100%FREE myvg

Now you can run the installer and pick the "something else" option, and select the logical volumes you just created for the use you intended.
