I downloaded the Windows 8.1 ISO file but my laptop doesn't have an optical drive. The only choice is to install it from USB. I found a Windows 7 USB making tool (the some works for Windows 8 as I found from Microsoft site).

No issues until now. When I run the tool it can't find my flash drive (SanDisk Cruzer Blade of 16GB) and upon lots of debugging I found that the USB drive is detected as static (fixed) drive. The tool won't recognize any static ones.

Can I make my SanDisk USB drive to be detected as removable?

  • You do know that Windows 8.1 has the ability to reset your installation which will set your system into what basically is a fresh installation state right? Since you have a Windows 8.1 license you should be able to use the Windows 8.1 on the Microsoft website to download create the bootable usb.

Answer here Flipping the Removable Media bit -- alternatives to BootIt?

You might want to reprogram your USB Drive by using Mass Production to flip the removable bit.

Alternatively - you can install filter drivers to disguise your USB drive as Removable or Fixed.

    There is no such program as "Mass Production." The other thread is referring to "mass production" as in the software used by the manufacturer in the factory. Nov 10, 2017 at 0:28
