After installing Ubuntu via a USB and restarting the computer it only boots windows. I checked on the BIOS and Ubuntu doesn't appear. I can boot into Ubuntu using the USB: it boots the menu: try Ubuntu, install Ubuntu, etc. then I press Esc and it shows the GRUB terminal, then I enter exit and the boot management appears. There, I can select Ubuntu which actually appears as a booting option (It doesn't in BIOS) and it runs the GRUB where I can select either Ubuntu or Windows.
I tried the boot repair inside Ubuntu and this is the report link: http://paste2.org/ykpn6NvZ
Thanks in advance.
