Wow, all this made me confused.gif

Doesn´t windows 7 get installed in UEFI mode when one install it from a disc on a UEFI based board?

and if not what is the pros and cons?


Care to explain in some simpler way about this, got rather curious but still confused.


I have a Asus Z68 board I just testing and my Win 7 installation was made from a disc on to a harddrive (no SSD) and the "Partition Style" is MBR (checkout the picture below), does that mean that the installation is in BIOS mode or UEFI mode?

I formated the drive before I did the installation.


Sorry for be such a noob but this is all rather new for me redface.gif

From the contributions of many, finally some answers and methods to get a true UEFI install going with Windows 7 on our ASUS motherboards. It became clear that the default configuration of a Windows 7 install disk is legacy MBR regardless of the fact that boot code and other info has been present on the install DVD. This only makes sense as when Win7 hit the market, we were still in a total MBR world. Well, we know that is starting to change now with Microsoft finally yielding to the market pressure that keeps growing (thank you Apple) now for UEFI operation.

This post is to give a starting point "how-to" for UEFI. Thanks to the many who have already been through this and put information up on the web in various places. I am sure with time, this will become truly automated option as Microsoft brings out their next OS and beyond. Anyway, enough of this --- on with the setup info.

This method uses a USB stick as the boot/install source. You cannot boot and install UEFI directly from the install disk. It will only install legacy MBR. Here we go.

(1) Obtain at least a 4GB USB stick drive.

(2) Format the stick in FAT32.

(3) Copy your MS Win7 64-bit DVD to the USB stick drive. Make sure you copy the file/folder structure EXACTLY as it is on the DVD.

(4) On the USB stick, go to \efi\microsoft\ folder and copy the BOOT folder.

(5) Go back to the efi folder and paste in the BOOT folder into the efi folder.

(6) The EFI folder should contain two folders -- MICROSOFT and BOOT.

(7) Using 7-Zip (or similar utility) on the USB stick, locate and go to:
\sources\install.wim\1\Windows\Boot\EFI and locate the file bootmgfw.efi.

(8) Drag this file to your desktop and rename it to: bootx64.efi. Now copy bootx64.efi to \efi\boot folder on the USB stick.

(9) You can now boot in UEFI mode from the stick and you will have this option to install Win7 in UEFI mode!

(10) Once done, verify your UEFI install with DISK MANAGEMENT and/or DISKPART utilities.

Other Notes:
In general, nothing else special is needed to do the UEFI install. Make sure your target hard drive for the install is set to GPT type. Most set ports 1-4 to AHCI mode, and ports 5-6 to IDE mode. Just connect your hard drive (the install target) and plug in the USB stick drive. During the first boot, USE THE F8 KEY TO SELECT THE USB STICK identified as UEFI in the boot device select menu as your boot source. You should be off and running.

I have not determined what the range of configurations of the hard drive partitioning is tolerated by Windows 7 at the beginning of the install. But it must be set to GPT. Windows 7 does look at the partitions and makes adjustments. I am going to do a few more test installs to see what Win7 can manage because it does want to finally end up with the UEFI partition set in a certain order. And remember you cannot see all the partitions -- some remain hidden depending on which utility you use to look at your GPT system drive. (eg DISK MANAGEMENT or DISKPART).

Anyway, there is my first step up the learning curve with UEFI. Hope this helps --- have fun -- I sure am biggrin.gif

P.S. I recommend you save your usb stick for future installs. Also it may be possible to move the Win7 disk files to other media (once tweaked) and boot/install with that media --- many possibilities.

Cheers --- Bob wink.gif

Yes windows install in MBR mode, but when you are in window 7 you can set it up to use drives larger then 2TB.

Here's the thread where most of this information came and there is even some steps to rebuild your windows installation disc so it boots in UEFI mode directly (second post in that thread).

http://www.insanelymac.com/forum/lofiversion/index.php/t184349.html

Also found this link that explains how to boot from the EFI command line your windows CD installation in EFI mode.

http://technet.microsoft.com/en-us/library/dd744321%28WS.10%29.aspx

I'll be in the same boat as you guys for this once the board arrives this week so I'll let you know how either goes but I'll probably re-image my win7 disk to boot in EFI mode by default to ease the steps (will also act as my disk backup)

Hi Praz, and all --- yes, much of this was posted by you, and others as well with similar information. You did an excellent job of spelling out the basic needs. As I noted, all the information that I posted was previously developed and scattered around the web, which it is, and there is much more to come.

I think you would agree that UEFI is far from a complete, clean alternative to MBR setups. For instance you cannot do functional image backups in Win7 while using UEFI. What we have now is just a first step toward a full, functional replacement for MBR. A good bit-for-bit copy program is needed to use the present UEFI to provide backup security. Any ideas here as to the best choice??? confused.gif

Anyway, thanks for your contributions and keep at it!! Windows 7 UEFI needs all the pioneers it can get right now especially. Too bad MS did not get on board as Apple did, early on.

Cheers --- Bob wink.gif

Hello Metarox --- good information! I knew there were better ways to go about this --- and I am sure we will see a full automatic install capability with MS's next version of Windows. It is not news anymore that they have announced full support for UEFI so we should expect to see it in the next version with full functionality. It may be a bit "clunky" until then but that is OK. Now is a great chance to learn UEFI and its capabilities. I will surely look over what you have mentioned here and learn some new tricks! wink.gif

Thanks --- Bob smile.gif

Another downside, at least from my experiences, is when updating/rolling back UEFI versions for the boards Win7 authentication breaks and needs to be reauthorized through Microsoft. A real pain for me when testing different UEFI versions.

Yes, the current spec and Windows implementation of UEFI is very vulnerable to "breakage". I read about this some time back and realized that once I set up my system, I needed to leave it be until something major happened to the design from Microsoft. It will be interesting to see what MS does with the future of their implementation for Win "X" whatever the next generation ends up being biggrin.gif

My main system remains an MBR system. I keep two systems -- one for my normal computer stuff including gaming, and then one that is a work-in-process for the next generation. That is where my Sabertooth is, and running presently in UEFI. At least this way, I can't mess things up too badly with ongoing tweak-and-test :-)

I do need to be able to backup my system and need to get a third-party disk bit mirroring or blind image maker to back up my UEFI system disk. Any ideas or experience with any other than Ghost?

Many Thanks ---- wink.gif

I know a few people were waiting for this including me,to look at before purchase.

English manual is now out for D/L @ ftp://ftp.asus.com.tw/pub/ASUS/mb/SocketAM3+/SABERTOOTH_990FX/E6674_SABERTOOTH_990FX_V2_u.zip.

No new bios yet.
