How to Fix my USB?

[focus]

I used UltraISO to make a a bootable usb to install windows but after it was created I can't see my USB anywhere anymore...
I tried:
- uninstalling it from device manager
- Diskpart clean
- HP USB Disk Storage Format Tool

In device manager the USB says Media and is greyed out.

boot up in safe mode to see if it's there if so and you can use it, something is boot up blocking it. run msconfig and look at the start up files disable them all and reboot. Are you using a boot leg copy of windows?
