# Windows – Unable to Make Bootable USB Stick From ISO

bootable-mediaiso-imageusb-flash-drivewindows

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:

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?

It would seem that bootsect was failing because the device was already bootable.

This morning I decided to try using it to boot with the Windows 7 Professional 64-bit installer image loaded on it, despite the failure, just to see what would happen. Surprise-surprise, it worked. -_-
