I was using Windows 10. Then I installed Ubuntu 18.04 LTS as multiboot. Grub2 replaced Windows bootloader.

I wanted Windows bootloader.

So I installed EasyBCD 2.3 on my Windows 10. Created a new Linux entry on it. When I booted I had two entries, but instead of booting to Ubuntu it booted to "grub4dos".

I used "boot repair tool" via live USB. It reinstalled "grub2". But now I have two boot loaders.

Grub2 loads first. Then, when I select Windows 10 from it, Windows boot loader loaded up. I have to select Windows from it to boot into Windows 10.

As I use Windows 10, regularly. I have to go through two boot loaders to get to my Windows 10.

I like to have either Grub2 or Windows bootloader which boots both OS with single click.

Please help.

I use Laptop with single HDD.

enter image description here

I had tried different options on EasyBCD but every time I end up using my "boot repair live usb" to reinstall Grub2.


-1- Rewrite Windows 10 Stock BootLoader
Boot with Win10 install media, got to console and run this

bootrec /fixmbr<br>
bootrec /rebuildbcd

-2- Test it: booting the PC should to to Win10

-3- Repair Ubuntu Boot with Ubuntu install media
BootUbuntu from LiveUSB
Get the drive device name with Gparted
Run those commands

sudo mount /dev/sdXY /mnt  # Example: sudo mount /dev/sda5 /mnt
sudo grub-install --root-directory=/mnt /dev/sdX # Example: sudo grub-install --root-directory=/mnt /dev/sda

    These suggestions are valid for older PC's with legacy BIOS, but not for modern ones with EFI based BIOS ! :) – cl-netbox Jun 18 '18 at 12:25
