How to update samsung's SSD firmware?

Go to https://www.samsung.com/semiconductor/minisite/ssd/download/tools. Go to the "Samsung SSD Firmware" section. The links there to go to standalone ISO images which you can either burn to a CD/DVD, or convert into a bootable USB drive (by following the Samsung firmware install guide or using unetbootin). Make sure to choose the link that matches your drive!


I ran into the exact same issues. Setting my BIOS "Boot mode" option to "Legacy" allowed my machine to boot the Samsung SSD firmware updater successfully.
