This may sound like a really dumb question but i somehow can't find the answer. I'm using the Samsung 850 Pro SSD with WIn7 on it, in a week or two ill be upgrading my hardware so i will starting with fresh windows installed. I want to securely erase my SSD using the Samsung Magician but i just can't find an option to make a bootable USB. Can anyone help me with this? I know it may sound stupid but im still kinda new to SSD drives and their way of formatting (this is my first time doing this).
If all you want to do is fresh-install the Win 10 OS (I'm assuming it's Win 10 you plan to install - you didn't say) on your Samsung SSD, just a simple format of the SSD is all you really need by way of preparation (as blazorthon informed you). There's really no need to carry out a secure erase operation - it's simply not needed unless you're currently having some untoward issues with the SSD.
I'm unsure why you're asking about creating "a bootable USB". Can I assume you're referring to a device that will contain the setup files so that you can fresh install Win 10 on your SSD? If that's what you're referring to, see...

Unless you choose to format the SSD before you install the OS, you will be able to proceed with the formatting during the OS installation process.
