I have a lenovo Z50 with Windows 8.1 installed on in. I replaced my optical drive with a 250GB SSD. I cloned my OS from C drive to the SSD. Now here's the problem, How do I get windows 8 to boot up from the SSD? I have tried to change the boot up option from BIOS but there's no option where I can change so that the laptop will start from SSD. Can someone please help! Thanks!
