Where can I download "bootrec.exe"?

I have my Windows 7 x64 ISO on my pendrive, but WinToFlash app forgot to install the MBR (again).

The only PC I have, uses x86 Win7 , so it won't install the bootrec.exe, since that is a 64bit binary.

I need the /boot/ folder from the Win7 ISO/disc. (32-bit)
Where can I download only that? Can anyone give me a link?

BootRec.exe is not officially available for download. However, you can extract it from any legitimate Windows 7 ISO.

You'll need something capable of reading a WIM file - 7zip should suffice for this. From the root of the ISO, open .\sources\boot.wim. From there, BootRec.exe can be found in .\1\Windows\System32\.

you can find it in the install.wim\Windows\System32\Recovery\Winre.wim\Windows\System32\bootrec.exe

Microsoft doesn't offer individual files from their operating systems available for download. However, you can legally and safely download the entire Windows 7 64-bit .iso from http://msft-dnl.digitalrivercontent.net/msvista/pub/X15-65805/X15-65805.iso

Or you could visit a friend and make a copy of the file from their computer...
