ASUS Z87 PRO issues with booting from a Corsair SSD

Hey folks. I'm generally quite happy with my new Z87 PRO motherboard, but I'm having a problem that I'd like to try to figure out a solution for.

Upon entering the UEFI BIOS (EZ mode) it allows you to drag the boot devices and arrange them in the priority that you want. The big problem is that my boot device (Corsair Force 480gb SSD) does not show up on the list. My options show as: Windows Boot Manager, the 1 tb hdd I have, and the BD-ROM drive.

If I go into the Advanced menu and go under SATA config, sometimes it will list my SSD there, and other times, it will be blank in that same slot. If I go into the Boot Menu, scroll down, and try to use the drop-down menu to select a primary Boot Device, my SSD is not on that list either, just the previous 3 that I mentioned and 'disabled' as a 4th option.

What happens every time I restart my PC is that I get a message that Windows was unable to start because of an inaccessible device. Windows then tries to repair the problem, and automatically restarts my PC.

The temporary workaround I'm using is to set my (empty) BD-ROM as the primary boot device. For some reason, after about 10 seconds, Windows boots from my SSD (which oddly is still not on the boot device list in BIOS...it just works after the BD-ROM activity stops.) This allows Windows to function until the next time I need to restart.

I've already tried a different SATA cable. I've already tried changing some of the boot settings, like making sure AHCI is enabled, trying fast boot enabled and disabled, turning SMART boot on and off...I'm kind of a noob (this is the first PC I've ever built) so I'm wondering if there is something obvious I'm missing here. Thanks for any help you can offer.
 
Solution
I had this happen.....had to change boot order on every boot to get to SSD. Solution:

1. Make sure SSD is on lowest numbered SATA port.

2. Open BIOS, set all to default settings, save and exit

3. Go back into BIOS and set boot order .... save and exit

Should be fine from there .... has worked in 2 different builds for me

Thank you! This worked perfectly. I didn't realize when putting this PC together that the SATA ports were numbered, or that it mattered. In my defense, they are numbered in a very stupid way on this mobo...instead of showing SATA 1&2 or 1-2 or 1+2 or 1/2, they just jam the numbers together. In other words, it shows on the motherboard as:

SATA_6_12
SATA_6_34
SATA_6_56

I'm sure to a more experienced person, they would get that right away, but 12, 34, and 56 don't mean anything to me right off the top of my head, so I just figured I would plug them all in and see if it worked. As a result, my SSD was in SATA 4, and would not show up as an option to boot from. Now it's in SATA 1 and everything has worked great. (The first time Windows came up, it made me restart, but that was it.) Thanks again.

Thanks for responding. This also would have gotten me on the right path to getting my SSD out of SATA 4.

Yeah, I have 3 piggies. They approve of my PC gaming habit because they get lots of time in my lap.
