I'm trying to use the Windows 7 USB/DVD Download Tool from the Microsoft Store to make my new 16 GB USB Flash drive bootable to install Windows. It worked the first time that I did this (for Windows 7 Pro 32-bit), but now it keeps failing at the end. (I'm trying to make it bootable with the Windows 7 Pro 64-bit installation DVD ISO.) I've tried to do this on two different computers (Windows XP Pro 32-bit & Windows 7 Pro 32-bit) with the same error:
Files copied successfully. However, we were unable to run bootsect to make the USB device bootable. If you need assistance with bootsect, please click the "Online Help" link above for more information.
Clicking the link just takes me to the Microsoft store homepage, and a search for
bootsect from there yields no search results. I've tried to burn a DVD twice using Sonic RecordNow!, but even though it finishes without "errors," the disk is unreadable. :( Does anyone know why this keeps failing and how I may fix it?
