No boot option for 850 pro in Z170x Gaming 7
« on: February 29, 2016, 12:23:36 am »
Just installed the Samsung 850 pro in my Gaming 7 (revision 1.0).  I installed Windows 7 Pro on the SSD and have installed all the required drivers from the Gigabyte installation cd.  My bios is version F6.  The OS installed with no problems and runs fine.  The problem is that the SSD does not show up in the BIOS as a boot option.  I can boot from it through the boot menu by pressing F12 during startup but that's the only way.  It shows up under SATA configuration (sata port 3), but not under the boot option menu.  Does anyone know why this is happening?  This is rather annoying considering I just spent a week trying to configure a 950 pro m.2 as a bootable drive with no success (ended up returning it).  I was hoping I wouldn't have any problems with the 850 pro since it's on the compatible list and operates via SATA and not via the NVMe architecture which has many known compatibility issues ESPECIALLY with this board, but here I am again.

Ok figured it out.  In case anyone else has this issue, boot into the BIOS, go to hard drive/bbs priorities under the BIOS features tab, make sure the SSD is in the first priority position.  This should now make your SSD appear in the boot option priorities choices.

You know if you set it up using UEFI the boot times are really fast.
