I just had time to look at the problem, it looks like MS has changed its loading. The problem is FAT32. As loog as it is FAT it forks fine, but FAT32 makes it unbootable. The only solution i found was to ditch FAT32 and use NTFS...

Forget Unetbootin.

Microsoft have supplied this capability for Windows 7.

But from the above link :
"When your Windows 7 ISO file is copied onto your chosen media, you can install Windows 7 by navigating to the root of your DVD or USB flash drive and double-clicking Setup.exe."

So neither the DVD nor the USB key are bootable, and you have to install Windows 7 from a runnng Windows OS? If yes, then it is nothing more an ISO extractor, ImDisk would be then more useful.

@ B1t Hunt3r
You can try the following:
  • Download the last version of Syslinux (3.83 at the moment).
  • Extract /win32/syslinux.exe
  • Open a command prompt window
  • Drag and drop the extracted syslinux.exe to the command prompt window
  • Add the needed parameters, so it looks like the following (replace X: with the drive letter for your USB stick)
    syslinux.exe -ma X:
  • Edit the syslinux.cfg file and add:
    LABEL w7
    
    MENU LABEL Windows 7 install
    
    COM32 chain.c32
    
    APPEND ntldr=/BOOTMGR
  • Extract /com32/modules/chain.c32 and /com32/menu/menu.c32 from the Syslinux archive and place them in the root of your USB drive.
  • Extract the Windows 7 iso to your USB drive.
You don't need the nt60.0 file.

Here's how I do it.

I use unetbootin to put the ISO files onto the USB stick. This will also install syslinux onto the stick to use as a bootloader.

I then download grub4dos grub4dos.zip

Extract that zip file and copy grub.exe into the USB stick into the directory: /BOOT
Now when you look in your /BOOT directory, you should see 'grub.exe' in there.

Go back into the root of the USB drive and edit the syslinux.cfg file. Add an entry like this:

LABEL WinPE

MENU LABEL Windows 7 PE

KERNEL /BOOT/grub.exe 

APPEND --config-file="find --set-root /SOURCES/BOOT.WIM;chainloader /BOOTMGR"

TEXT HELP

ENDTEXT

Just for the record, that is an old (and also buggy) version of grub4dos.

Read here:
http://reboot.pro/14/page__st__1


Depending on Syslinux version, there is also an alternative way to chainload grub4dos from it ( COM32 and chain.c32 ), see here:

ATM i like to boot Win7PE by this command

label Windows Vista/7 Installer

menu label Windows Vista/7 Installer

COM32 /chain.c32 fs ntldr=/bootmgr


So far it has worked perfectly.

Sure :dubbio: :
http://syslinux.zyto...mboot/chain.c32
unless I am mistaken this only applies since 3.85, and as seen in the given link:
http://reboot.pro/11867/page__st__1
4.00 and later have even added capabilities.

The tool is in an ever evolving status, and one may need to pay particular attention to the syntax used with which version, since it changes often, see also this:
http://reboot.pro/11943/
(new "APPEND" syntax)

;)
