I tried today a flash drive created with Ubuntu's Startup Disk Creator and the alternate 12.04.1 64 bit ISO. I have also tried copying the LiveCD files on a primary GPT partition, but with no luck, I just get the grub shell, no menu, no install option. Live USB was created by dd'ing the iso onto the full disk device (i.e. This happens on a ubuntu-12.04.1-desktop-amd64 iso used on a LiveUSB. So it would be the boot info from the liveCD boot in bios mode. As a result I can't install ubuntu in EFI mode.

I'd say this has something to do with UEFI since the LiveCD boots in bios mode but not in efi mode.īesides, I am not sure my boot info will help, since I can't boot the LiveCD in EFI mode. I have used the Ubuntu 12.04.1 Desktop ISO (I have read somewhere that it is the only one that can boot in EFI mode). I've tried the nomodeset kernel option (as well as removing quiet and splash) with no luck. It starts loading (up to initrd), but I then get a blank (black) screen. The main issue about this tablet is that it ships with an installed Windows 7 in (U)EFI mode (GPT partition table, etc.), so I'd like to get an EFI dual boot with Ubuntu.īut it seems I can't boot on the liveCD in EFI mode. It operates an Intel Sandy Bridge architecture. My tablet is Samsung Series 7 Slate ( XE700T1A-A02FR (French Language)).
