    How to dual boot from the same ssd but different partitions in Windows 10


    Hi,


    On my notebook I had an installation of Windows 8.1 for work on drive C: and an installation of Windows 10 on drive D: for private use. Now I upgraded the Windows 8.1 version to Windows 10 and now when the notebook boot's up the option to choose the Windows version disappeared.


    How do I enable the option to again get the prompt to choose the Windows version I want to boot into?


    BR

    How to dual boot from the same ssd but different partitions in Windows 10

    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
