Help with dual booting Win 10 and Ubuntu

This is your whole problem. What you should have done is to put GRUB in sdb1 and Windows Manager in sda1 so that Windows Boot Manager is in control.
So what suggested above will not make any difference. GRUB is still in control of booting process.
To fix your problem. You will need to:

1. Move GRUB from sdb to sdb1
   |grub2 - how to move grub boot from one partition to another in linux - Ask Ubuntu
2. Rebuild The Windows Boot Manager ie. create a brand new BCD to boot Windows 10.
3. Once done with steps 1 and 2 above. Windows will not know UBUNTU exists and vice versa.
   Depend on the priority set in the BIOS, it will boot directly into that OS.
   However, you can boot either one from Boot Menu (Using whatever key that your Laptop assigned to: F2, F10....)
   Since I hate Dual Boot and seldom boot into Linux, I will stop here.
   Now, go to step 4 to create dual boot.
4. Use Easy BCD to create an entry for dual boot with UBUNTU. Once done, you should get a nice GUI dual Boot Menu
   and it will boot directly into either Windows or UBUNTU.

Here's the detailed explanation: How can I move windows 10 boot files to another drive to allow linux

 

Grub Loader missing

my Dual boot of ubuntu is missing after i installed virtual box in windows 10 so how to get my grub boot up option

 

Well, another set of Windows 10 patches installed, another trashing of my GRUB dual boot System: UBUNTU GRUB FIX

Well, another set of Windows 10 patches installed, another trashing of my GRUB dual boot system, another evening spent repairing it. When is Microsoft going to stop their upgrades destroying dual boot systems?

I know Microsoft don't want anything on my PC except Windows, however you can't always get what you want! If you make me choose between Windows and UBUNTU, you lose!

ADVICE for anyone using Ubuntu in a dual boot system with Win10 on a x64 architecture as a WIN10 patch upgrade WILL wipe your GRUB boot system out.

1) have a UBUNTU boot disk handy. Always!

2) When a Windows upgrade destroys GRUB, use the UBUNTU boot disk and boot up into "Trial" mode (i.e. don't reinstall UBUNTU). You may need to re-order your boot sequence and also ensure that secure boot is DISABLED else this may not work. Booting from dvd
takes time - be patient!

3) Ensure you are connected to the internet - you may need hard wired connection as wireless does not always come up in Trial mode

4) Open a terminal and download the GRUB repair program:

"sudo add-apt-repository ppa:yannubuntu/boot-repair" <CR>

"sudo apt-get update" <CR>

"sudo apt-get install -y boot-repair && boot-repair" <CR>

MB sudo doesn't need a password when you boot into "Trial" mode.

5) When the boot repair program comes up, find your way to the advanced tab aand select "grub installation / repair" option, and follow any instructions given

6) Remove UBUNTU boot disk and reboot to Windows, open a admin enabled terminal (not powershell) and enter:



"bcdedit /set {bootmgr} path \EFI\ubuntu\grubx64.efi" <CR>



you should get a "success" message

7) reboot, and the grub menu should appear. Enjoy!

This works on Ubuntu 14 and Ubuntu 16 LTS coupled with Win10.
