Hello
I purchased an ASUS P9X79 Pro and I have been having a terrible time trying to install Windows 7 (x64). I’m not completely inept when it comes to building PC’s but this is my first UEFI motherboard, and purchase in three years.
For reference my new kit is:
Asus P9X79 Pro
i7 3930K
32GB (8X4GB) DDR 3 1600MHz G.Skill CL9 Ripsaw Z
OCZ 240GB Vertex 3 SSD
Sapphire ATI 7950 HD
Coolermaster Gold 1200W PSU
The problem I’m facing is issues trying to install Windows and I cannot tell if it’s my hardware or if it’s the mobo or both. But where possible I have tried my new hardware on my other working PC (Asus P6TSE) and they appeared fine, but obviously I cannot try the 3930K on that Asus board.
On my new set-up when trying to install windows I’m setting up through the UEFI installation process. Initially I let windows automatically setup the EFI/GPT partitions and then I choose disk part to manually do the process myself. On all attempts (12 and counting) windows either failed the install or installed then failed at a later date after some windows updates.
The problem I’m facing is during the install and it’s first reboot windows fails to start and returns with various error codes, some are 0xC0000225 or there other ones which I fail to remember are due to windows boot loader stating it’s corrupt. Either way when you boot and it ends up in that screen there is no way to pass that point except for a reinstall (the boot gets stuck in a loop returning to that error screen no matter what you do).
I have tried installing windows on the p9X79 with a different graphics card in and did not use my 7950, as a test I was using my 5950HD and it installed smoothly but ended up with the same issues once installed and failing to reboot correctly. I also tried flashing the bios with previous versions and later versions, all with mixed results.
On occasions where windows did install correctly I was able to load the mother board drivers etc, but it would eventually fail on various reboots returning the same error (0xC0000225) with no option to correct the windows boot loader. On successful windows 7 installs it would fail after windows updates, or not let me install SP1 no matter what attempts I tried – a complete mixed bag of failed install/win update scenarios.
What I want to understand is could I have corrupted the UEFI boot options stored in NVRAM?
If I have a UEFI board does anyone know if the Asus p9X79 can install windows normally bypassing the UEFI process or could this cause problems since the board and bios I assume is catered towards UEFI?
Could the issue be setting up a GPT disk on my SSD?
