I have Windows 7 x64 bits on my TravelMate P446-M laptop. The laptop comes with HDD that is already partitioned into two NTFS partitions around 250 GBytes and one hidden partition for recovery. I installed Ubuntu LTS 16.04 using Flash Memory. During the installation, I re-partitioned the second 250 Gbytes partition into the following three partitions:

  1. 50 Gbytes to mount the root '/' as ext4
  2. 190 Gbytes to mount '/home' as ext4.
  3. A partition for swap around 12 Gbytes.

I selected the place of the boot loader to be the whole hard-disk i.e. did not specify any partition. After I finished the installation, I am not able to find Ubuntu in the boot menu not even in the boot tab of the msconfig in Windows. I tried the boot-repair tool on live Ubuntu on the Flash Memory but nothing changed.

Your partition table looks OK, and your EFI System Partition (ESP) has boot loaders for both Windows and Ubuntu. Your Boot Repair output, though, lacks information from sudo efibootmgr -v, which reveals the computer's NVRAM boot manager entries. My suspicion is that your firmware is defective and is forgetting or ignoring these entries. This is a problem that crops up repeatedly, particularly with some brands. See, for instance:

I managed eventually to fix the problem. I did a clean installation of Windows 10 x64 having UEFI boot mode and secure boot disabled. Then, I installed Linux Ubuntu 16.04.1. Finally, in Windows I run the following command in the command promt:

bcdedit /set {bootmgr} path \EFI\ubuntu\grubx64.efi

After that I started to see the Grub Boot Menu and be able to select Ubuntu or Windows. However, for the original settings with Windows 7 x64 with boot legacy mode and Ubuntu 16.04.1, I was not able to show the Grub Menu.
