  • What does a U disk mean? When swapping SSD between an old and new computer, there may be a BIOS/UEFI compatibility problem. – Melebius Jul 12 '16 at 13:30
  • @hizqueel I appreciate your contributions, your suggestions are generally good. But please make your comments more descriptive - "improved formatting" is just not good enough when you improve much more - here the reviewer has to figure out what you really did. – guntbert Jul 12 '16 at 14:35
  • Udisk means "USB disk" or maybe "live USB", I guess it is sometiing about UEFI and legacy mode. – bai yudong Jul 15 '16 at 00:47
  • What installation media are you using? If it's a DVD I'd try and burn another possibly at a lower speed. Faulty USB, DVD or corrupt installation files can do this. – Alec. Jul 12 '16 at 13:25
