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.
