Gigabyte GA‑Z77X‑UD5H Won't boot to selected drive!?

[nightrider1470]

I have disabled all other hard drives in the BIOS and it then boots fine, but then always enables other drives on my next boot causing me to have to enter the BIOS again to select my windows drive again

Is there any way round this?

Maybe my SSD needs to be connected to a certain sata connection on the motherboard?

Got my SSDs on 0 (boot/OS) and 1 (games). You can download the manual from gigabyte's website. My board is Rev 1.0.

From the manual this is how they sit, the even numbers being next to the board.
GSata3 7 GSata3 6
Sata3 1 Sata3 0
Sata2 3 Sata2 2
Sata2 5 Sata2 4

I recently updated my bios , might be worth trying as since doing this my Oc is much better. If yours is not upto date maybe this will help with the boot issue?

I had it too & not long after an update from MS for my W7.
