It is common question asked by I.T Professionals that "How to check version of your Operating system CD/DVD but before installing". It is pretty easy to check any Windows 7 version (x86 or x64 / 32 bit or 64-bit).

Check your DVD, if it contains followings files folder hirarchey, that can be considered a x64 / 64-bit Windows 7 DVD. bootmgr.efi file is only an addition there.

Advance Level:

If you have Administrative rights on your system, Just type CMD in start otherwise;

Start > All Programs > Accessories > Right Click on Command Prompt and select Run as Administrator;

Type this command in your cmd windows; dism /Get-WimInfo /WimFile:xyz:\sources\boot.wim

Where xyz is your DVD drive letter that contains a Windows 7 DVD.

Expert Level:

If you think that you are an expert level User of Windows, you can download Windows 7 Automated Installation Kit from Microsoft Website. Install it (Note: It will work on Vista SP1 or newer). Remember, it is almost 1GB+, don't download it if you don't need it. Anyhow, when you finished installation of Windows 7 Automated Installation Kit,

Start > All Programs > Deployment Tools > Command Prompt

Insert Windows 7 DVD and close any autoplay popup and type at Command Prompt

imagex /info xyz:\sources\boot.wim. In this example xyz is your drive letter that contains a Windows 7 DVD.

output contains the line <NAME>Microsoft Windows PE (x86)</NAME>, then it's 32-bit. If it says (x64) then it's 64-bit.

Alternatively, type imagex /info xyz:\sources\install.wim, and check for a line starting with <ARCH>. If that line lists <ARCH>0</ARCH> then it is 32-bit, otherwise it is 64-bit. Hope that will work for you :)
