Problem using Win7 USB/DVD download tool (concerning bootsect.exe)

Hi, I am a student, (at the Florida Institute of Technology).  And I used digital river to buy a version of win7 professional for my laptop.

Now the laptop i am currently using is xp 32bit.  I got it right when vista was coming out and it was supposed to work with vista, but the reviews were so bad that i never used it.

So now i want to install 64bit win7, and i use the tool (and read the help) but I cannot get the correct version of bootsect.exe, so that I can create a valid bootable USB on this computer, so that I can format and install win7 64bit on this same computer.

OK there seems to be a bit of a confusion around botosect.exe. I don't believe this tool is required at all to make a bootable USB device. Let me see if I understand the question first:


I am running a 32-bit Windows Operating System, have access to a 64-bit Win7 ISO, and would like to use a USB device (instead of burning the ISO to a DVD) to install 64-bit Win7 to a target computer.



1. Plug in a USB device that is 4GB or bigger.
2. Find the disk number of the USB device:
    Open up an elevated command shell, run diskpart.exe.
    Within diskpart, run 'list disk'. The output will list all disks on the computer. From looking at the size, infer which one is your USB disk and note down the disk number.
3. Correctly format the USB device:
    Run diskpart.exe and enter the below commands one by one.
        select disk <disknumber of your USB disk>
        create partition primary
        format fs=ntfs quick label=Win764
        assign letter=Q
    Now you should see a "Q:" drive in Windows Explorer. This is your USB disk.
4. Mount the 64-bit Win7 ISO:
        Windows does not have a built-in ISO mount feature. So you will have to use a third-part tool. I suggest "Virtual CloneDrive". Once you have downloaded and installed Virtual Clonedrive, navigate to the folder that your ISO file is in, in Windows Explorer. Right-click on the ISO file and select "Mount". After this, all your ISO files should show up in a drive called "I:".
5. Populate the USB disk:
    Copy all files and folders from I: to Q:.
6. UnMount the ISO:
    In Explorer, navigate to the folder that has the ISO, right-click and select UnMount.
7. Boot from USB:
    Turn off the target computer, plug in the USB device, turn on the computer, get to the BIOS boot options (using F9 or some other key, depends on your computer), select USB boot, and you should see setup run.

Hope that helps.

Hi nkarl2009,

Welcome to Microsoft answers!

a. Do you get any error message whatsoever?

To make the USB device bootable, you need to run a tool named bootsect.exe. In some cases, this tool needs to be downloaded from your Microsoft Store account. This many happen if you're trying to create a 64-bit bootable USB device from a 32-bit version of Windows. To download bootsect:

1. Login to your Microsoft Store account to view your purchase history
2. Look for your Windows 7 purchase
3. Next to Windows 7, there is an "Additional download options" dropdown
4. In the dropdown, select the "32-bit ISO" option
5. Right-click the link and save the bootsect.exe file to the location where you installed the Windows 7 USB/DVD Download Tool (e.g. C:\Users\username\AppData\Local\Apps\Windows 7 USB DVD Download Tool)
6. Once the file has been saved, go back to the Windows 7 USB/DVD Download tool to create your bootable USB device

To install 64-bit of Windows 7 on your computer it is essential that your computer supports 64-bit computing.

The terms 32-bit and 64-bit refer to the way a computer's processor (also called a CPU), handles information. The 64-bit version of Windows handles large amounts of random access memory (RAM) more effectively than the 32-bit version.

Follow the steps mentioned below to find out if your PC is running the 32-bit or 64-bit version of Windows and what edition of Windows is on your PC:

Click Start, right-click My Computer, and then click Properties.

• If "x64 Edition" is listed under System, you’re running the 64-bit version of Windows XP.
• If you don’t see "x64 Edition" listed under System, you’re running the 32-bit version of Windows XP.

The edition of Windows XP you're running is displayed under System near the top of the window.

Refer the link below for more information on frequently asked questions about 32-bit and 64-bit Windows:

I've got the EXACT same problem (bought my win 7 64 bit ed. from digitial river), but your solution won't work for me! I don't have a "microsoft store account" because I purchased the ISO image from digital river, and the never provided me with an account number (or the bootsect file I need).

Any other solutions?

Yeah, same issue. Purchased through Digital River and don't have a Microsoft Store Account, so I can't find the right bootsect.exe file to create a bootable USB drive.

As many have mentioned before me, people who obtained a 64 bit copy of Win7 through Digital River cannot access the specified version of bootsect.exe to successfully create a boot USB for the 64 bit Windows 7 on a 32 bit computer. I too request you to look into this and contact us with a viable solution for us as soon as possible.

I think I can make a bootable USB if I can get hold of someone's 64 bit computer, and create the boot USB on their system. But right now I do not know anyone with such a system, so please look into the matter.

We DON'T have access to Microsoft store because we bought from Digital River. Please think more about the situation than put a link to something we saw previously.

Same issue; Running 32 bit XP Pro downloaded the Student Win7 64 Upgrade ISO from Digital River. Downloaded the Windows7 USB DVD Download Tool and tried to install on a blank formatted 8 GB USB drive  Works fine  ALMOST.. but get the error that need the bootsect.exe
After researching this it appears this has been going on far too long. If they have a solution it should be posted, if they do not then they should say flat out that what we are attempting to do is not possible. I would have then purchased their DVD! In my case I have a DVD drive I can use.
