UEFI Windows 7 64Bits installation using a USB drive

Hi guys. I follow the steps of the following guide. The usb drive restarts normally but the windows installer interrupts with "missing files" message...

File: \windows\system32\boot\winload.efi 
Status: 0xc000000f
Info: The selected entry could not be loaded because the application is missing or corrupt.

Select allOpen in new window

Any ideas??????

Trying to install Windows 7 64bit on SSD. Asus p8z68 deluxe motherboard i7 2600k intel processor.
Motherboard supports UEFI bios....

(I copy the \EFI\microsoft\boot folder or I cut copy (delete it). )

I follow the steps of the following guide before i get missing files reports....

Your USB drive must be bootable, and be formatted with a FAT32 File system. The UEFI is unable to identify a USB drive formatted with NTFS as a UEFI boot device.
Make a bootable USB device for UEFI and GPT:

    Open the Start Menu, type diskpart, press Enter
    Type lis dis, press Enter
    Type sel dis X (where X is the number your USB drive shows up as), press Enter
    Type cle, press Enter
    Type cre par pri, press Enter
    Type act, press Enter
    Type for quick fs=fat32, press Enter
    Type ass, press Enter
    Type exi, press Enter
    Copy everything from the Windows 7 installation DVD onto the USB key (a simple drag and drop will do; if you have an .iso extract first).

Your USB drive must also contain the directory and file: \EFI\Boot\BOOTX64.EFI. This is the EFI installation bootloader extension.
If you do not have this directory, or file on your USB drive, fear not. This is how you create it.
First, create a new directory called Boot inside the \EFI directory
You will then need to copy all of the files from the \EFI\microsoft\boot directory, up one level into the directory you just created (\EFI\Boot).
Next, use 7-Zip to open the archive located at: *:\sources\install.wim (* is the drive letter of your USB key that holds the Windows 7 installation files)
Inside the archive, find the file located in folder "1" \Windows\Boot\EFI\bootmgfw.efi.
Copy this file to *:\EFI\Boot\ location you created earlier. (Not in 7-zip) (This file is also available from any current windows 7 installation). It is located in the C:\Windows\Boot\EFI directory.
After copying the file to the EFI\Boot directory, rename the file in *:\EFI\Boot\bootmgfw.efi toBOOTX64.EFI. You should now have an EFI bootloader directory for Windows called *:\EFI\Boot\, with all of the files copied from the EFI\microsoft\Boot. Directory, and the newly named BOOTX64.EFI
Your install media (DVD/USB) must be inserted into your PC prior to powering it up. This will allow your UEFI to register your device (DVD drive/USB drive) as a UEFI boot enabled device.

Also I should let you know that I cannot find the file  the file \Windows\Boot\EFI\bootmgfw.efi. when I Use 7-Zip to open the archive X:\sources\install.wim so I copy it from another normal windows 7 installtion (found in c:\Windows\Boot\EFI\bootmgfw.efi.)


Thanks people
