USB making tool for Windows detects flash drive as fixed, need to be seen as removable

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?

Solution 1:

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.
