I've got a problem after installing Ubuntu on an external drive with Windows 10 on my compute.
My bios is not working anymore and I have a blank page. After the bios, if I don't ask it, it goes on an Ubuntu gnu command line. Something quite similar to this : https://www.google.co.uk/search?q=gnu+grub+version+2.02+boot&safe=off&rlz=1C1MSNA_enGB697GB697&source=lnms&tbm=isch&sa=X&ved=0ahUKEwiambfhxL7NAhWmJ8AKHWV7ANwQ_AUICCgB&biw=1920&bih=955#imgrc=_4yFwpV7aJGGpM%3A
Can't understand what to do.
I do not care if i loose everything or whatever if my computer can work again.
