Windows 10: How to remove any one of your OS in your computer when it's set to dual-boot

Hey all!


This is a tutorial to show you how to remove any one of your OS in a single computer when it's dual-booted. Here, I'm speaking about how to remove Android x86 from your Windows 10 computer. This method will also work in other OS like Ubuntu, Linux, MacOS, etc.

1. Boot your computer into Windows and reach the desktop.
2. Open Run press Win key + R and type msconfig and hit Enter.
3. When it opens, go to the Boot tab. Select the other OS installed. Here, I'll select Android x86.
4. After selecting it, click Delete. When prompted, click Yes or similar option.
5. Quit msconfig and restart your computer. If you're lucky, you'll boot into Windows.
6. If you've disabled fast startup before dual-booting, enable it so that Windows can boot up faster.

That's all! Simple, right?

Dual Booting with Windows 8.1


The procedure below will allow you to boot Windows separately or in dual boot configuration.
Here's what I recommend to do:

1. Disconnect the drive containing Windows 8.1
2. Install Windows 10 with one drive connected.
3. After step 2, reconnect the drive containing Windows 8.1
4. Boot up Windows 8.1. Open disk management and take a note of the drive letter of Windows 10 OS.
   NOTE: if you boot up Windows 10, then take a note of Windows 8.1 drive letter
5. Open Admin command prompt and type: bcdboot X:\windows where X: is the drive letter of Windows 10 (Windows 8.1 if you boot from Windows 10 in step 4)
6. Reboot the PC. You should have a dual boot screen.

NOTE: To break off the dual boot setting, Win+R->msconfig->boot and delete the none default entry on the list.

 

Dual booting OS

Dave is correct, However, If you take ownership of C:\ System (Windows) when you are booted to each OS. Then depending on why you are asking this, as in you do not want others to access the other OS, then Take ownership as mentioned. Then you MUST add your
user name in the list with full permissions/control. Then you would remove all users in the list

EXCEPT KEEP THESE>>YOUR NEWLY ADDED USER NAME, SYSTEM, AUTHENTICATED USERS

REMOVE USERS>>>ADMINS, USERS & EVERYONE

Now for an OS you are booted to. You can add other users in the security users list for C:\ and/or C:\Users & C:\Users\Programs and Programs (x86) & C:\Windows

if there is others with user accounts on that OS. And then grant them the permissions you want to allow.

Because you have removed the user ADMINS, so they need to be granted permissions to access the OS as normal.

Look in Part 2 for detailed steps for ownership, permissions and sharing

Connect PCs and users for sharing Windows 10 to Windows 8/7/Vista/XP
