  1. Re: Why Doesn’t A Clone Of My Bootable ubuntu Boot?

    Just like live installer, external drives boot from /EFI/Boot/bootx64.efi which is an UEFI:USB entry in UEFI boot menu.
    Not from an 'ubuntu' entry.
    You can create an ubuntu entry, but when drives...
  2. Re: My PC wont load GRUB after I installed Ubuntu alongside WIN10

  3. Re: My PC wont load GRUB after I installed Ubuntu alongside WIN10
