Download Tool to format the
USB drive and then copy the Windows 7 installation files to it from the ISO
image you provided.
You'll see a Status of Formatting for
several seconds, followed by Copying
files. This part might take as long as 30 minutes, maybe even longer,
depending on which edition of Windows 7 the ISO file you have is from, as
well as on how fast your computer, USB drive, and USB connection is.
Tip: The percentage
complete indicator may sit on one or more percentages for a long time. This
does not mean anything is wrong.
-
The next screen you see should say Bootable
USB device created successfully.
You can now close the Windows
7 USB DVD Download Tool program.
The USB drive can now be used to install Windows 7.
-
Boot from the USB device to
start the Windows 7 setup process.
Tip: You may need to
make changes to the boot
order in BIOS if
the Windows 7 setup process doesn't start when you try to boot from the USB
drive. See How
To Change the Boot Order in BIOS if
you've never done that.
Tip: If you still can't
get the flash drive to boot, and you also have a UEFI based computer, see
Tip #1 below for help.
Note: If you arrived
here from How
To Clean Install Windows 7, you can now return to that tutorial and
continue installing Windows 7. See How
To Install Windows 7 if you
weren't doing a clean install or you're not sure what kind of installation
to do.
When creating a bootable USB device, I am getting an error about bootsect
To make the USB drive 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 may happen if you're trying to create a 64-bit bootable USB device from a
32-bit version of Windows. To download bootsect:
-
Login to your Microsoft Store account to view your purchase history.
-
Look for your Windows 7 purchase.
-
Next to Windows 7, there is an Additional
download options drop-down menu.
-
In the drop-down menu, select 32-bit
ISO.
-
Right-click the link, and then 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).
-
Once the file has been saved, go back to the Windows 7 USB/DVD Download Tool
to create your bootable USB device.
src
the Windows 7 USB DVD Download Tool will also fail right at the end (after spending
all that time copying the files to the USB!) because it cannot execute the
64-bit version of bootsect.exe present in the ISO.
Rufus or similar should work just
fine though:

I used Rufus and succeeded. Log is at D:\siung_download\SW\Windows 7 64
