I'm trying to install Lubuntu 15.04 on a Sony Vaio VGN-P21Z along with Windows XP. I've booted into a live USB Lubuntu and begun the installation from the inside. I thought I could save some time and used the included partitioning tool instead of partitioning the HDD inside Windows; it warned me this could take a lot of time, but I'm sitting here for 5 hours and nothing has happened on the screen. It just shows the little spinning circle. Why is it taking so long? And, is it safe to turn off the system? It seems this could take forever.
