Just trying to install wheezy in UEFI mode again on the Intel DH77EB motherboard, now with firmware version 99 and the latest daily build of debian-testing-amd64-netinst.iso. Still the same result: the resulting Debian installation is unbootable. Here is output when I install and boot Ubuntu 12.10: $ sudo efibootmgr --verbose BootCurrent: 0002 Timeout: 1 seconds BootOrder: 0002,0003,0000 Boot0000* debian Vendor(99e275e7-75a0-4b37-a2e6-c5385e6c00cb,) Boot0002* ubuntu HD(1,800,2f000,017b4fcf-b5a3-4549-a8d6-a94cb7eb699a)File(\EFI\ubuntu\grubx64.efi) Boot0003* UEFI : SATA : PORT 6G 0 : INTEL SSDSC2CW120A3 : PART 0 : OS Bootloader ACPI(a0341d0,0)PCI(1f,2)03120a000000ffff0000HD(1,800,2f000,017b4fcf-b5a3-4549-a8d6-a94cb7eb699a)AMBO In Debian rescue mode after installing Debian, replacing the previous Ubuntu installation: # efibootmgr --verbose BootCurrent: 0003 Timeout: 1 seconds BootOrder: 0003,0002,0000 Boot0000* debian Vendor(99e275e7-75a0-4b37-a2e6-c5385e6c00cb,) Boot0002* ubuntu Vendor(99e275e7-75a0-4b37-a2e6-c5385e6c00cb,) Boot0003* UEFI : USB : 0.00 : PART 0 : OS Bootloader ACPI(a0341d0,0)PCI(1d,0)USB(1,0)USB(1,0)HD(1,10a74,380,27f931c5)AMBO Running 'grub-install /dev/sda' in Debian rescue mode causes the debian line to change to this: Boot0000* debian HD(1,800,f3800,f8636d01-62af-4d23-9ab6-5b22c5ffd5e6)File(\EFI\debian\grubx64.efi) But like I said in a previous email, upon reboot this disappears, and reentering rescue mode shows the "Vendor(99e275e7-75a0-4b37-a2e6-c5385e6c00cb,)" line for debian instead. Notice how there is no UEFI SATA hard drive in the efibootmgr output on Debian. That's probably the problem, since the debian line needs to refer to that device, but I have no idea why Ubuntu has this properly and Debian lacks it. -- Kenyon Ralph
