Trying to Fresh Install Windows 7/[8] on Windows UEFI Boot Mode

[apocalypzez]

I've been trying to install windows 7 on a uefi boot mode. I have tried both methods; USB and DVD none of these
are working. I have flashed my evga gtx 680's to uefi compatible bios as well. In the bios csm is disabled and*
secured boot is set other OS. Once I do this and restart I do get the intel RST tab and Intel NIC Card Tab. I've
created RAID0 via the intel RST tab and set boot media to UEFI: DVD/USB. The system does boot and initiates
the windows installation process and reaches to the windows start logo, which comes up after Windows
loading*Setup File has*been completed. I keep this message "the current bios setting do not fully support*
windows uefi mode. The csm setting has been changed for better compatibility. And then the usual F1 to enter
Bios setup or F2 to continue.*I have tried almost everything from fresh creation of UEFI USB Windows
Install drive to disabling those legacy device detections like PS/2 Keyboard.

What am I doing wrong here I only have my 840 Pro SSDs connected and all unwanted device are left disconn-
-ected.
Steps followed for simplicity sake:
1. Flashed the GPUs with UEFI Compatible BIOS
2. Disconnected all HDD and changed CSM to disabled and secured boot to Other OS.
3. Created UEFI USB Windows install boot disk.
4. And trying to install windows 7.

Set CSM: Enabled
Boot Device: UEFI and Legacy
Boot Device #1: Windows Boot Manager

I'm using Windows 8 x64 Pro in UEFI mode. No experience with Windows 7 in UEFI

Thx for the tip! But why is that we MVE owners cannot disable CSM? I mean, when I read the guide from ASUS RIVE setup page (I know it's a different model), they say to disable CSM, but can't we can't do the same with MVE?? I have an ASrock Z77E-ITX and the installation went butter-smooth (with a UEFI: DVD boot option not USB). Also if i enable CSM and set as uefi first or uefi only to all the other options I don't see any RAID config option!!!

Anybody not yet curious about fully utilising the UEFI boot option?? Anybody out there have tried an MVE with CSM disabled??

Please provide inputs!! Any guides or instruction out there in the Internet takes care of you install, DVD OR USB, but I've yet to find a proper guide that explains from BIOS itself??? At the moment I hav followed Sean's Guide from overclock.net (www.overclock.net/t/1156654/seans-windows-7-install-optimization-guide-for-ssds-hdds)

finally i gave up and followed your instruction, limitz, that did work like a charm. however, i am still curious as to why it doesn't work with csm completely disabled, like the guide for RIVE - an older model...!!!

No idea what this is. Will try and find out.

CSM disabled, I guess only works with win 8 x64, hence the issue. But now I've got windows 8 x64 pro installed with fast boot enabled, CSM disabled, secure key other OS with GPT partition but now it takes 45+ seconds to boot from POST to Desktop/Metro UI!!!! I followed couple (mainly 2) of different guides each time and they are as follows:

Sean's Guide @ OCN
Arkhi's Guide @ EightForums

Dunno where I'm getting myself wrong but something tells me the only thing I learnt with trial and error was BIOS settings (so could this be where the issue lies) and there isn't a definitive guide on this one for this board. The only piece of information I could find in ASUS's website was under Rampage section.

Bios used were modded1707 with 12.6 OROM with v12.5.0.1815 IRST s/w drivers, as well as default bios v1707 with built in OROM 11.5 with v11.7.01013 and 12.5.0.1066 (currently using) IRST drivers. Currently on stock bios v1707 from the MVE download page.

hey, I used this http://rog.asus.com/forum/showthread.php?30520-RAMPAGE-Windows-8-7-UEFI-Installation-Guide&country=&...
, csm disabled, it could be a driver issue? I think I'm booting anywhere between 5 to 13 secs
