Bios does not set priority. Hackintosh?

Question

Windows

There is a hard drive with win7 and a ssd with a hackintosh (El Capitan). Sitting on a hackitosh, the monitor suddenly goes out and the computer just turns off. (notebook asus n56v). Now it is impossible to set the boot priority in the BIOS, there is no bootloader in which you could select the bootable axis (in my opinion, there was a clover). In the sata section - both hard drives are visible. Also, through programs on wines, it was possible to enter the file system and pull out the necessary files. (MacDrive). This program did not show errors and writes that the disk is healthy.
I, as I understand it, the bootloader has flown (maybe). Advise how to be. By the way, I didn’t roll the hackintosh, it would be a pity to lose a perfectly tuned system.
Thanks
