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:

diskpart
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
exit
bcdboot C:\Windows /s T: /f ALL
exit

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.

thank you!!

AWESOME! I really need to learn more about bcdedit!

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

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.

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:

+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.

Unless a command line does not fit the SSD drive setup, no luck with this one.

The''Grub''pseudo-terminal was still there after restart. Same for the command line in post #23. <<Topgun>> method is best, not to say faster and easier:)

Note: See solution in post# 29.
