Is it just as safe to use Tails and do your business on VirtualBox as a USB/DVD? I was unable to get it to work on my DVD 'cause if shitty Windows 8, it would always get stuck at the "Loading, please wait..." part, and I don't have a USB with it anymore. I'm hoping that it's fine to use it on VirtualBox
Yes, Windows 8 is shitty. Change you BIOS setting to legacy mode to run TAILS.
