Hi everyone, I recently bought a Mac mini server with a faulty disk (bottom one) and a broken SATA cable. I replaced the top disk with an SSD and put the working one in the bottom tray without the SATA connector (for now at least).. Problem is... I can get the mini to boot from the SSD which has a Windows 8.1 install on it, but cannot get it to boot it from a working Yosemite install on an external drive. The boot just hangs at 50% of the progress bar. I've also tried to run a USB install of Mavericks and the internet recovery (cmd+r) but all I get is the Apple logo and the spinning wheel. Could the logic board be fried or damaged? The mini chimes normally and everything seems to be in good working order... and as I said Windows runs just fine. I'm lost!!! Please help!!!
