    Hola gents,
    I tried every tool and tip posted earlier in this thread, but none of that worked for me.
    I have two newer Asus boards (which come with UEFI BIOS). They just won't list the USB stick as a bootable device, no matter what I tried so far.

    But. I was searching around for a while and came up with a solution that does work.
    At least, it worked for me to install Windows 7 x64 for both Asus boards.
    Here's the how.

    1. Elevated command prompt:

    Code:
    diskpart
    lis dis
    sel dis 1 (Replace 1 your USB Drive!)
    cle
    cre par pri
    sel par 1
    act
    format fs=fat32 label="Windows 7" quick
    ass
    exit
    exit
    
    2. Extract all files from ISO to USB stick (I will refer to the stick as the 'x' drive below).

    3. copy x:\efi\microsoft\boot\ to x:\efi\boot\ (yes, the entire structure, one level up).

    4a. If the ISO is the same as the OS you're using, copy this file:
    c:\Windows\Boot\EFI\bootmgfw.efi
    here (note that you will need to rename, too after copy):
    x:\efi\boot\bootx64.efi

    4b. If the ISO is not the same as the OS you're using, use 7zip to open this file:
    x:\sources\install.wim
    and extract this file somewhere on your HDD:
    \1\Windows\boot\efi\bootmgfw.efi
    then copy it here (note that you will need to rename, too after copy):
    x:\efi\boot\bootx64.efi

    5. Insert the stick into one of the back USB2 slots prior to powering it up.

    6. Hit <Del>, then F8 and it should be listed there, hit enter to boot.

    Note: When you boot from a USB stick, you won't be able to install Windows without having to create a system and a reserved partition. I am pretty sure that's a bug rather than an intended. If you want to avoid having to create these extra system partitions, you will need to boot from the DVD (internal or external optical drive).

    If you are trying to boot to UEFI the Windows Tool will not work as is, since it formats the usb to NTFS. UEFI will boot to Fat32 not NTFS. If that is your case, you can do two things, either edit your registry to force the Windows tool not to format, and then you just format the usb fat32 before running the tool.

    OR you can create the usb with the tool, and then format the usb to fat32 and then extract the iso to the usb drive. Formatting the usb drive will not remove the boot record that the tool creates. So then you would be able to use the USB as a bootable UEFI usb drive.

    Editing the registry saves having to extract the iso to the drive, since it has already been formatted to fat32 and the tool simply extracts the iso once and makes it bootable.

    Code:
    To bypass formatting the USB device within the tool:
    
    1. Ensure the registry key "HKCU\SOFTWARE\Microsoft\ISO Backup Tool" is created.
    
    2. Create a new DWORD value named "DisableFormat" in this location and set the value to 1.
    
    NOTE: The USB device should be formatted manually before running the tool.

    UltraISO has an option to write ISO to USB. Tried it once & the key was bootable under UEFI...

    Please,
    Is there a list of good reasons why you should make a boot-able USB ?
    I can possibly make one for win xp 32bit and win 7 pro 64 bit ?
    but,
    I'm having a hard time getting the usb to work...

    Is there an easier way ?

    On win 7 the Dell site says to upgrade the bios with a bootable usb
    but i just can't figure it out.

    The win xp bios update worked great with just installing it like an app...

    Is there a section here I'm supposed to know about and be there ??

    Many thanks in advance

    ADA and ignorant here
