Windows 10: I can't get rid of dual boot option after installing RemixOs

    You want to use a program such as MiniTool Partition Wizard to delete the existing EFI system partition. Once the existing EFI system partition is deleted, use diskpart to create a new FAT32 partition and bcdboot to put the Windows BCD back on it:

    select disk 2 <- that's the drive with the EFI system partition according to your screenshot in post #12
    create part pri
    format fs=fat32 quick
    assign letter=t
    bcdboot C:\Windows /s T: /f ALL

    You don't need to use Minitool or diskpart to do this. Just open Admin command prompt and type:
    mountvol U: /s
    del /f /s /q U:\*.*
    bcdboot C:\Windows

    Reboot your PC

    Or you can leave the remixos bootmanager where it is and reset the NVRAM to use MS bootmanager. From elevated cmd (not powershell):

    bcdedit /set {bootmgr} path \efi\microsoft\boot\bootmgfw.efi

    This just updates the Boot Manager path shown in your picture on post 12 to the Windows default.

    When you install another OS they generally make another sub-directory in /EFI/ and set themselves to be loaded by default.

    AWESOME! I really need to learn more about bcdedit!

    This method works, but the lx07 one don't. Will post the result later.

    Actually I don't know much about it.

    I have to reset path as I use rEFInd. After every Windows or MacOS upgrade I have to run bcdedit /set {bootmgr} path \EFI\refind\refind_x64.efi as both OS try to grab the loader for themselves. No Linux install tries the same trick it seems.

    You can set anything really - for example (the mountvol and dir are only to show you the contents - they are not needed):

    I found rodsbooks good for EFI. MS documentation is limited (at least I can't find anything decent for bcdedit).

    I suggest you open your own thread if you have a different problem.

    IMHO, the method I gave above will work every time you need to rebuild the EFI System partition which will rebuild everything from scratch, hence will delete all the multiple entries of "Windows Boot Manager" and all the junk left over from RemixOS as shown in post #14.

    If you open the Admin Command, copy and paste the 3 commands. It will take less than 2 seconds to complete the task.

    [Solved] Removing Grub Alongside Win 10 in UEFI Mode

    Tuesday, February 27, 2018

    Secure Boot, Fast Boot and Fast Startup are enabled.

    I made a few fresh installs of Kylin xx. 3 alongside 16299.248. For testing purposes, related partitions were deleted immediately after.

    The given command lines by lx07 (post# 27) didn't work (boot loader was still there), but Topgun method is unbeatable (post# 22) = no leftover = restores Win Boot Loader default.

    To get rid of Grub or Linux boot loader, after deleting partitions and resizing C: or D: drive, open Command Prompt in Admin mode:

    1. mountvol U: /s
    2. del /f /s /q U:\*.*
    3. bcdboot C:\Windows
    4. Restart

    As shown in terminal:

    Microsoft Windows [Version 10.0.16299.248]
    (c) 2017 Microsoft Corporation. All rights reserved.
    C:\Windows\system32>mountvol U: /s
    C:\Windows\system32>del /f /s /q U:\*.*
    The process cannot access the file because it is being used by another process.

    +1 @Topgun. The process rewrites the UEFI partition in a few seconds and is easier than Legacy mode: bootrec.exe /fixmbr. D:\ is Quick Access location.
    Thanks a lot.
