I have already installed Win7 on my machine. There are 3 partitions that have been done. Now i want to install another OS which is fedora 16 on my laptop but not on the virtual machine. i.e I want to dual boot Win7 and fedora 16. When i start the installation after inserting DVD i reach a page : and then select Use free space which is 20GB , but i get a message not enough space available. Why is this so ? How can i install fedora 16 KDE ?
