Cannot install OSX Mavericks
I have an iMac with Intel Core 2 Duo 3.06 ghz, 4GB DDR3, 700GB HDD space and running OSX 10.6.8 but when I go to install Mavericks on the internal HDD I get the message 'This disk cannot be used to start your computer'.
Can anyone tell me how to get around this, obviously Snow Leopard is on this disc and started the computer up.
iMac, Mac OS X (10.6.8)
