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

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:

+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.

 

@lx07

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*Smile

Note: See solution in post# 29.

 

@MikeMecanic - I've really no idea what you are on about, what your question is or how (if at all) it relates to this thread.

@topgundcp gave the correct way to rebuild ESP for Windows. I only mentioned you could alternatively change the path the nvram holds for the default bootmanager so your EFI firmware will take this as first option. This worked for the OP (and me). Perhaps it doesn't for you - it really depends on your UEFI firmware and how well it conforms (or not) to standards. Mine is Apple which is (rather surprisingly) fairly compliant. Lenovo (on the other hand) notoriously isn't.

Personally I use a EFI bootmanager (rEFInd) which will look on any connected disks to find any other boot managers (or boot loaders). I have rEFInd, MacOS, SysLinux and Windows in my ESP at the moment. Grub was always too complicated for me so I don't use it.

There are many ways to skin a cat - that is for sure *Smile

 

Indeed, there are many ways. I was simply looking for an easy method to get rid of Grub and found one in this thread. Thanks!
