How to Fix Error - Black screen blinking cursor windows 8.1, week old system.?

Black screen blinking cursor windows 8.1, week old system.

last sunday I turned on my desktop all I got was a black screen with a blinking cursor at the top left of the screen.
I've tried everything from start up repair to system restore using the installation disk.
Nothing works, I pulled that HD installed it into
an external case and everything is there, OS, docs, pics, music.
The motherboard is giving me an AE bios code in the leds, which means "boot to legacy OS" and I don't know what that means.
a friend tells me that the
master boot record's pointer to the operating system is corrupted.
Ok, but how do I fix that? also why happened in a weeks old computer (built by myself).
My motherboard is Gigabyte GA-Z87X-UD5H, CPU is an Intel Core i5-4570
3.2ghz 6mb cache, ram is GSkill ripjaws ddr3-1866 pc3=14900 16gb.
Any suggestions???????????????????????????
