Downgrade to El Capitan

[Lifecrest]

I installed Sierra but am having problems with it and would like to try out El Capitan instead.
I am on a dual boot system with 2 SSD's, 1 with Sierra and the other with Windows 10.
Is there any special way I have to do this other than wiping the Sierra disk and installing El Capitan?
Will the windows drive still be able to boot?

Thanks

I am wondering the same thing. I installed Sierra successfully but was having a lot of trouble getting the Radeon 280x video card to work. So, I downloaded El Capitan and created a new USB drive with Unibeast (the correct version for El Cap) and I started up the PC. It went into the Clover boot loader (as normal) and I chose the USB drive to boot from. It went through the entire loading process (full bar on the Apple Logo) and then it just went to a black screen. Not sure how to get it working.

I already removed the 280x card and reset the BIOS to Auto for the on board graphics card (which has worked just fine in the past). Any help would be much appreciated. Thanks!
