[Bug 1508203] Re: Grub freezes with external usb devices connected

[Phillip Susi]

Are you booting in bios mode, or UEFI mode?  This certainly sounds like
a bug in your bios, since grub uses that to access these devices.

  computer during boot, grub fails to start (laptop freezes at logo
  display)
