How to Delete a Listed Operating System at Boot in Windows 7

Information

This will show you how to delete a non-default operating system in Windows 7 from the list in the Windows Boot Manager that allows you to select a OS to run at startup.

EXAMPLE: Windows Boot Manager
NOTE: This is the boot screen where you select what operating system that you would like to start. By default, you have 30 seconds to choose another operating system before the default operating system will start automatically.

Here's How:

1. Open the Start Menu.
A) In the search line, type msconfig and press Enter. (See screenshot below)

B) Go to step 3.

OR

2. Open the Control Panel (All Items view) and click on the Administrative Tools icon and System Configration.
A) Close the Administrative Tools window.

3. Click on the Boot tab. (See screenshot below)

4. Select the operating system you want to delete that is not set as the Default OS, and click on Delete. (See screenshot above)
NOTE: If the OS you want to delete from the list is the Default OS, then you will need to change the default operating system first.

5. Check the Make all boot settings permanent box, and click on OK. (See screenshot below step 3)

6. Click on Yes to confirm. (See screenshot below)

7. Click on the Restart button. (See screenshot below)
WARNING: This will restart the computer immediately. Make sure you save and close anything open that you do not want to lose first.

That's it,
Shawn

I have Window XP Pro 32bit and had installed Windows 7 64bit RC1 on a sperate hard drive. I have since formatted the drive with Windows 7 on it and still have the dual boot manager. Unless I am there to choose the XP the system will try to boot to Windows 7 that isn't there anymore. How can I get rid of the dual boot manager and automatilly boot to XP? Thanks for your help in advance.

Hello WildCard, and welcome to Seven Forums.

You can use EasyBCD in the Add/Remove Entries section to remove the Windows 7 boot entry from with XP. You will also need to install .Net Framework 2.0 for EasyBCD to work in XP though.

Hope this helps,
Shawn

Thank You so much Brink! I had just about given up hope. I had tried some other things but was having no luck and your solution worked like a charm. Took me less than five minutes and the problem was solved. Thanks again for the help.

You would think that after dual booting the last 3 operating systems on
more than 1 computer a person would remember these things. Alas no.
Thanks for jogging my memory, Doug

You're welcome Doug. We have so much to remember, that it's not hard to forget something every now and then.

To stop dual booting, you should be able to use this method within Vista or Windows 7 and then extend that "C" partition into the one created for the dual boot. Will this work as long as the default is to the left on the "disk management" screen?
