I have an HP laptop with Windows 10 installed. I tried to dual boot Ubuntu 16.04 on it. During installation, I got grub-install failed on /dev/sda fatal error. To fix it I, used boot repair: it showed success. But after reboot, it still loads directly to Windows 10.

It is not showing grub screen at start.

I don't know how to fix this.

  • is /sda6 flagged as an ESP partition? You should have used /sda3 for the ESP partition when you installed Ubuntu. Your system may not recognize 2 ESP partitions on a single drive. And third, did you change boot order in the system settings? (check this last one first). – ravery Nov 26 '17 at 17:18
  • Ya I tried changing boot order using command prompt bcdedit command as said in the result of boot-repair – Mani_MR Nov 26 '17 at 17:22
  • I said in System Settings, not Windows. EFI firmware that allows OS selection will often ignore the order set by bcdedit. – ravery Nov 26 '17 at 17:27
  • Can u tell me how to do that, since I'm new to linux, I don't know how to do that – Mani_MR Nov 26 '17 at 17:29

    it has nothing to do with linux .... press a function key while booting, the specific key depends on the computer; though F2, F10, and F12 are common. Keep trying until you get the system settings, not the onetime boot selection screen. – ravery Nov 26 '17 at 17:32

Hold down and keep pressing the shift key during the boot process and your machine should boot into the Grub menu.

  • It boots to windows only not boot into Grub – Mani_MR Nov 27 '17 at 15:35
