    Ubuntu 14.04 doesn't boot from boot menu on Haswell




      I have installed Ubuntu 14.04 desktop in UEFI mode on Intel haswell system. Here I am observing that boot entry is being created as "Ubuntu" but while selecting it to boot is causing boot failure and coming back to UEFI BIOS setup. Now if I change the EFI\Ubuntu\grubx64.efi to EFI\Boot\Bootx64.efi from shell then it is booting. Alternatively if I create a new boot entry pointing to EFI\Ubuntu\grubx64.efi then also booting is working. This problem is not seen Asus Z87 and Asus P8 series system. After doing some searching I found that similar issue has been seen in DELL servers with Suse Linux ftp://ftp.dell.com/Manuals/all-products/esuprt_electronics/esuprt_software/esuprt_operating_system/novl-suse-lx-entps-srvr-11_User%27s%20Guide_en-us.pdf and as per the cause mentioned in the document is "This is caused due to the way Linux creates the GUID Partition Table (GPT) partition.". But I want to mention that this issue on haswell system I have seen only with NVMe device. When I install Ubuntu 14.04 in UEFI mode in an AHCI device on the same haswell system this issue is not coming, I mean it directly boots to Ubuntu without any workaround. Also like I have mentioned already when I install Ubuntu 14.04 in UEFI mode in NVMe device on Asus Z87 system that also boot to Ubuntu without any manual intervention. I just want to know what exactly is causing this issue. Also Linux doesn't create usual /dev/sd* for NVMe device. NVMe devices are listed as /dev/nvme0n1 and the partitions are as /dev/nvme0n1p1,/dev/nvme0n1p2 and so on. But if it is a problem with Ubuntu itself how come the same is working on Asus system ? Is there any issue in haswell UEFI setup also ?
