I installed kali Linux and now my laptop won't boot at all. I can't get cds to boot into a recovery environment. I've tried to boot Hirens cd, ultimateboot cd, systemrescue cd and it just spits them out and restarts. Only certain cds will boot: windows 8.1, helix boot cd, kali linux, ubuntu 15.04. What do I do to resolve this problem? Thank you for your help.
