Q: Mac mini restarts during boot up
I have a 2012 Mac mini that restarts halfway through booting up. The restarts began while the mini was in sleep mode and required a force quit to make it stop. Now the mini will begin to boot but when the progress bar is about half way filled the screen goes white for about 15-20 seconds, then goes black for a few more seconds and then the mini attempts a restart.
I have unplugged the power cord, but that did not help. I have also tried holding the command and 'd' keys down during boot but nothing changes.
Thanks in advance for any help.
Mac mini, iOS 9

Has my disk died?
Most likely either that or some other hardware fault.
Make a "Genius" appointment at an Apple Store, or go to another authorized service provider. You may have to leave the machine there for several days.
Back up all data on the internal drive(s) before you hand over your computer to anyone. There are ways to back up a computer that isn't fully functional—ask if you need guidance.
If privacy is a concern, erase the data partition(s) with the option to write zeros* (do this only if you have at least two complete, independent backups, and you know how to restore to an empty drive from any of them.) Don’t erase the recovery partition, if present.
Keeping your confidential data secure during hardware repair
Apple also recommends that you deauthorize a device in the iTunes Store before having it serviced.
*An SSD doesn't need to be zeroed.
