    Got an hp envy from a friend who destroyed the master hard drive. I replaced the hard drive. When I tuen the computer on, I get an error; "Invalid signature detected. check secure boot policy in setup" The computer initially came with windows 8 and all I have are the 5 recovery discs. How do I get this working?
