title: Tails OS hangs at bootstrap
body: <p>I tried all that I can... Ok, all starts that I wants to install Tails OS 3.12 on my usb. I downloaded *.img file from the official website. I tried several programs (Universal Usb Installer, etcher, rufus), but when I change priority in BIOS and reboot computer starts on a start window with changing keyboard and language and then, when I click on "Start Tails" it starts glitching in left top corner, it freezes and doesen't do anything. I waited a half hour but it didn't work, then I tried to download an *.iso file from non-official site and got the same result.</p>
  
  <p>All information that I can say: computer: Acer Nitro 5, OS: Windows 10 x64, Security boot: disabled, Usb device not in list of problem devices: USB Kingston DT50, Tried with: (official)<em>.img Tails amd64 3.12 and with (non-official)</em>.iso Tails 3.12 amd64, tried with this programs: Usb Universal Installer, rufus, etcher.</p>
  
  <p>Please help.</p>
