I could really use some mentoring on how to complete my install
I've got 10.11.6 running on an SSD, but I can't complete the boot using the SSD if its mounted to an internal SATA port. In fact I can't even see other SATA drives (HDD or DVD) that would normally be (not currently) attached to my internal SATA port, and I can only boot into Clover and begin to boot from the SSD; the boot fails when it tries to find the root device. The only way I can fully boot the OS is to use a USB boot drive and then select the OS drive, and the OS drive has to be connected to USB (via SATA adapter), and not to the internal SATA. I've got great video and audio (compliments of the GeForce 8400 GS), and I've got RTL8811au (Ourlink AC600; btw: their drivers install nicely), and I'm currently testing Sleep functions; everything seems to work well and I've created a Time Machine drive that's connected to my USB 3.0, as well as applied some El Capitan patches from the App Store. Oddly enough, I can boot from an old Kalyway DVD and see my internal SATA drives, so I don't think this is a HW or BIOS issue.
If you happen to know anyone that might be able to help, I'd appreciate a reference or an intro!
