[QUOTE="lclev, post: 1731418, member: 307555"] Not sure what happened. Try resetting the [URL="https://support.apple.com/en-us/HT201295"]SMC[/URL] and the [URL="https://support.apple.com/en-us/HT204063"]PRAM/NVRAM[/URL]. If that does not help you might try stripping it down to just one drive - the original boot drive - so there is no other option for booting and see if it will select it and maybe give you a working screen.
