Issue
First of all, hello everybody, it's my first post here, sadly reporting a probable bug...
I've already reported the issue to Asus support, but since it is an OC case they've said I should turn to you guys here.
Hope you can help me out.
Got a problem with booting up windows...
The problem is easily reproduced (every time) on my machine. Running an Intel I7 5960 @4.5GHz
(bus speed 125MHzm 36 multiplier) and G.skill Ripjaws in XMP profile (3GHz)... nothing out of ordinary.
I've ran all possible benchmarks and stress tests (CPU and memory) for a couple of days and
all passed flawlessly (RealBench among others). The whole system is stable as a rock. At least if I can get it to boot to windows...
The thing is that my system does not boot to windows (get a freeze on the ROG loading screen and later a blue screen) in 90% of the time,
but if I press the DEL key and enter BIOS before the windows bootup and not change anything just press F10 (save setting) and ENTER,
the system will go into reset and boot into windows flawlessly.
I did that more than 40 times and the system always booted to windows without any issues. If I just turn on the system or do a reset without entering BIOS prior
the system will probably hang. It never hangs in POST stage though.
It really looks like a glitch of some sort… How is the boot procedure different if I enter BIOS and not change anything, press F10 and ENTER (auto restart afterwards), compared
to a regular boot?
I've tried this with UEFI secure boot or without (pretty much tinkered with all the boot options) - it is the same. In BIOS 1401/1502, also no change.
Update 18.8.2015 - SOLVED:
Found the reason - SATA support and its Boot drive only option.
If I save with the "Boot Drive Only" option, windows loader always freezes, otherwise it boots up normally.
It wasn't an OC issue after all.
