WHEN CREATING A BOOTABLE USB DEVICE,I AM GETTING AN ERROR ABOUT BOOTSECT
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 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.
