If you are being prevented from entering BIOS, I find it hard to believe the OS has anything to do with it as the BIOS is what initiates it, meaning BIOS comes first. How can it be prevented by something it hasn't loaded yet?
If it was me, I would disconnect the hard drives and start the computer to see what happens.
If I go no where with that; leaving the hard drives disconnected I would then clear the CMOS with the jumper on the motherboard. and try again.
The BIOS doesn't depend on the OS, it's the other way around. The BIOS WILL load without an OS and you should be able to access it, especially is you reset it by clearing the CMOS.
Once you get into the BIOS, turn off the computer, reconnect the hard drives, turn on and get into the BIOS and configure everything accordingly.
It's possible you BIOS is set for quick boot (nothing to do with the OS, it shortens the POST time), clearing the CMOS will disable it (or should).
That's what I thought from post #4 on previous page but come to think of it, a few years back when I did a lot of heavy OCing's and I used EVGA MB, came with an application that you could install as a Windows Application. This application will allow you to alter BIOS settings from Windows and will take effect on next reboot.If you are being prevented from entering BIOS, I find it hard to believe the OS has anything to do with it as the BIOS is what initiates it, meaning BIOS comes first.

Having said that, I think he might have some application modifying the BIOS after Windows booted up or perhaps, the possibility might be when you turn on Fast boot and Windows could modify the BIOS.
So OP, when you have an opportunity, let us try to boot up Windows, turn off Fast Boot option then set it to Safe Boot followed by a reboot and do it at least 2 times to see if that's a possibility and of course don't forget to keep tapping on DEL key.
Excellent thinking. Same is true on my ASUS P8P67 Deluxe Rev B3. Forgot about it; never let the Windows app change anything though. The app it is used, among many other things, for doing "software" OCing.

When I enabled fast boot in the Toshiba utility on my laptop, it altered the BIOS setting and it prevented me from getting into BIOS because it skipped POST completely. Logging in and disabling Fastboot using the Toshiba utility fixed the problem.
On a Desktop, clearing the CMOS should do the same thing if you can't disable it anywhere else.
Two weeks ago, I installed Win8 in my two-year-old computer. I have tried countless procedures to try to regain access to my BIOS Settings. Finally yesterday, I tried to reset my BIOS to factory settings as recommended in ASUS online troubleshooting, but I still could not access my BIOS Settings to complete that procedure. NOW MY COMPUTER WILL NOT DO ANYTHING!! Boat anchor anyone??
Today, Microsoft Win8 Technical Support said that they cannot help me because my motherboard is probably NOT compatible with Win8. Thay said that their Pre-Install Compatibility Tests do NOT check our computers' hardware.
Later today, ASUS replied to my earlier email to say that the P6X58D-E may NOT be compatible with Win8.
Has anyone installed Win8 successfully with the ASUS P6X58D-E or similar motherboards, and then been able to access the BIOS Settings?
If not, be warned -- I think that I will have to buy a new motherboard with the new UEFI-BIOS, and a new CPU because of my attempt to use Win8 with this motherboard!!
You cannot Brick a motherboard by installing an operating system, no matter what.
A motherboard will work and POST even with a hard drive NOT attached, it has no impact. The BOIS is stored on a ROM chip, which in turn stores its setting on an erasable CMOS memory.
The ONLY way to brick a motherboard is by botching a BOIS update, even then you may still recover.
Software installed on a system drive cannot and will not prevent BIOS access.
Software that interacts with the BOIS may change setting in the BIOS, such as Quick Boot, and clock rates, etc. But when the computer is turned on, the BIOS is in full control.
If you cannot get into the BIOS, there must be something wrong somewhere other than the operating system.
Find the evidence; remove the hard drive and see if it POST's.
If it does not; logic tells us that the BOIS has a problem. My course of action to remedy a defective BIOS would be to flash it by downloading an updated version of the BIOS and the utility to flash it from a bootable CD.
I say all this based on your firm belief the the motherboard is not POSTing and "doing nothing".
I would also suspect graphics adapter in the even of a black screen at boot with nothing at all displayed ever.
Tell me: Did you erase the CMOS using the jumper on your motherboard? If you have not done this yet, please do it and report back.
