Hello, I have replaced my HDD with a new Samsung SSD and my 4gb RAM with 8gb Crucial RAM. My SSD is completely empty so I put the windows 7 CD choose the right option from BIOS but nothing. Its saying "Reboot ans Select proper Boot device or Insert Boot Media in selected Boot device and press a key". I tried to boot from a usb but the same. I also converted my old HDD into an external and tried to boot from there, nothing. Whats the problem??
