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?

Found a "bootsect.exe" on ZippyShare using Google, and it works. HOWEVER, this is not really safe (even if Avast says so), so the question remains open. – Shiki Jun 14 '11 at 10:18
I doubt you'd be able to download folder folders such as those.. without having to resort to "seedy" places. Perhaps I can upload it somewhere. – Sathya Jun 14 '11 at 11:01
I'd appreciate that upload. But seriously... Microsoft doesn't provide a legal way for people? :/ – Shiki Jun 14 '11 at 12:19
you can borrow a Windows DVD or download a Windows DVD over torrents and use your key and remain legal. – Sathya Jun 14 '11 at 12:30
@Sathya - I'm using MSDN ISO. But this happened to me a lot of times. Downloaded the ISO from my MSDNAA account. Made the (there are some options here) USB install "disk", and then it wouldn't boot. Now, you don't have a PC where you can fix things ... worse if you have a PC with XP and so on. Downloading the whole ISO again (since you used YOUR PC to do that), takes some time. – Shiki Jun 14 '11 at 13:05

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\.

If this is true I believe it should be marked as the best answer. – Vinicius Rocha Oct 23 '15 at 17:54

Or simply download the entire .Iso installer file of the windows OS you are using and look for it in the folders or simply do a search in that directory.

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

Sources: This SuperUser answer, which provides a full list of ISOs available for download, as well as that answer's original source.

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

Are you sure that bootrec.exe is inside ISO? I have have browsed original Windows7 ISO content and found no bootrec.exe. There is only boot\bootsect.exe. – dma_k Oct 4 '15 at 11:33

Hiren's Boot CD contains several boot environments that include that tool, among others (Try Mini Windows XP). You can download it here:

You can also install grub on the drive using a linux distro which will automatically scan and add all available operating systems on the drive to it's loader. Note removing the usb drive woun't affect booting.
