I can boot in UEFI mode from a daily build iso flashed to a USB stick, using the A10 BIOS update.
Steps: 1. Download and install BIOS update A10 from Dell (in Win 7 - I dual boot) 2. Download the daily build iso from ubuntu.com and make a bootable USB stick 3. Reboot the computer holding down F12 4. When the boot menu appears, choose to boot from USB with UEFI mode 5. Boot into Ubuntu (I'm 'trying without installing') Seems OK now, can anyone verify? -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1025283 Title: [Dell Precision T7600] LiveCD/USB will not boot in UEFI mode Status in “linux” package in Ubuntu: Incomplete Status in “linux” source package in Raring: Confirmed Bug description: I tried to boot from the LiveCD in UEFI mode as I wished to install my UEFI capable workstation in UEFI + GPT mode. If I boot in legacy mode, it boots up without a problem but of course, does not allow me to install in UEFI mode. Seems to perhaps indicate that the disk controller is having a problem.
