    I found very interesting the UEFI Bios options and it's graphics interface.

    Here's an introduction of settings that could be done (.pdf document):
    Best Practices for UEFI Driver & Option ROM

    By now it seems UEFI Bios is automated with OS install without to having choosing, as it is already set to legacy OpRom & UEFI Boot.
    I did notice that a lot of newer motherboards boots in UEFI by default. If so, then there will be no further action required by the user. Thanks for the info!

    If I need to reinstall Windows 7 in UEFI mode ... shall I delete and create all partitions again ?
    Or is enough when installing to select partition 3, format it and press next ?
    In partition 1 will be deleted and added new boot files from the newer install or there will be a mess with the older files and so on ? Also on partition 2. That's why I asked if to delete and create from scratch everything ...

    Thanks ...
    While it's been a while since this was pointed, it has only been brouhgt to my attention recently.

    Personally speaking, I would say that deleting all partitions and recreating it is the safest method. GPT partitioning is quite a little bit complicated since it is dependent on unique IDs. It's been a while since I manipulated with GPT disks, so I forgot if it is safe to manipulate only the data partition (e.g. formatting it) and still boot safely.
    Thank you ...

    You're welcome! You know, now that I think of it, the boot files are stored in a different partition (ESP). It should be okay theoretically.

    If you have question do let me know, and I apologize for late replies.

    The issue is that yesterday I played a bit with EFI partition and EFI bios and I manage to make it disappear that Windows Boot Manager option and I need it to reinstall. :) Didn't know how to recover it. I've tried to boot with the cd, but nothing.

    Look for an option in BIOS Setup to disable Legacy BIOS, then EFI Boot disk should appear in BIOS Boot Order Priority list so you can set it first, install per the tutorial to a HD wiped with Diskpart Clean Command so that it will format it GPT.

    Yes indeed, newer motherboard Bios are booting on both... UEFI + Legacy OpRom.

    Therefore people are being able to directly install from the DVD/CD drive and their install CDs.

    Updated bios of newer motherboard also allowing to boot on "UEFI only" with windows 8.

    I don't have such an option in bios.
    I have an Asrock Extreme 4 Z77 mobo.

    I dont' see in the SPecs that that mobo has an EFI BIOS. Study your Manual to be sure: ASRock > Z77 Extreme4

    What settings did you change?

    Hi all,
    I've done a UEFI install of Win7, 64 bit into a OCZ 120GB SSD.
    When I use diskpart to list volume, I found only two partitions instead of three..
    In other word, the 128MB MSR partition is missing.

    I got only this OCZ SSD and two raid volume (created in MBR) controlled via an Adaptec Raid Controller on my pc.

    MY questions are:
    1. how can I get the 128MB partition back?

    2. Will this missing of 128MB likely casued by the two raid volume which was created using my previous pc running BIOS/MBR?
