Guys, I just bought Lenovo Ideapad Z510 Laptop with Windows 8 preinstalled in it.
Now, I want to dual boot my laptop with Windows 7. Although I am not sure but I read somewhere that disabling the Secure boot will allow me to install Windows 7 on my laptop with Windows 8 already installed. So, if it is true than how do I disable secure boot and if not then please help me to make my laptop dual boot.

Access your BIOS. The setting will be found (and disabled) there. Be sure to save/apply after making the change.

Try booting up from windows 7 DVD or USB

If you get an error message about windows disk not containing an authorised operating system you know secure boot is on ( in Uefi bios)

You need to make space by shrinking a partition unless you already have a drive partitioned into c: & d:

Gparted live Linux cd image can do this for you if you only have a c: partition
