I want to install Mac Snow Leopard in a virtual machine, but I can not do the installation process, I have read that I need to use iBoot, I already downloaded it but it throws me an error that is: bios disk read error at sector: 00000011, and Now I download another iso of Snow Leopard but it stays working, can someone tell me how I can install Mac Snow leopard? or some program that works in windows to develop applications for iOS:
