I'm using Q584(Fujitsu). Its CPU is Z3770 and it uses 32bit UEFI.
At first I tried install Ubuntu on my tablet, NO boot device is detected but I found out that 32 bit efi is need.
So I used 32bit efi and I saw GRUB succeccfully. But When I select "try Ubuntu without install", I could see no progress but just black screen. no changes and I should reboot manually.
