Hello everyone, I have the solution to your problem "removing an operating system when you have several". Here is the procedure:

1 (optional).- Backup all your personal data on an external drive or a CD.

2.- Format the partition where the operating system you want to remove is located (to format, go to "Create and format disk partitions" for Vista or simply right-click on the drive in My Computer and select format)

At this point, you might think it's over, but no!!!!

3.- To remove it 100% from your computer, go to Administrative Tools found in the Control Panel (I think it's located in System for versions older than Vista) otherwise for Vista type "administrative tools" in the search bar, if that doesn't work, type "motherboard". Then a page opens with several options in the form of independent programs, you need to choose "System Configuration", go to the part of the program called Boot (the different sections are at the top of the page) then remove the operating system.

To check that everything works

4.- Go to "Show advanced system settings" then "Boot and Recovery" then settings, and in principle, there should only be 1 operating system left.

Here are the 4 steps to successfully remove an operating system from your computer; I hope this helped you.

See you!

Hi!!!
Actually, you go to start then run
you type boot.ini and it will display a page where your operating system and others will appear if they are on other partitions. If yes, you close everything and go to control panel then system then advanced
then startup and recovery then settings then modify in startup you will find three lines like this so you delete the 2 inactive ones
multi(0)disk(0)rdisk(0)partition(1)\WINDOWS="Microsoft Windows XP Home Edition" /fastdetect /NoExecute=OptIn
be careful with what you are going to do don't touch the active line it's your active operating system... good luck

Hi  @emmeline, Post #6 :  You could say hello, please, and thank you; thanks for understanding it :-)  Why do you want to remove one of your installations of Microsoft Windows XP?  Do you know how to use Notepad; it’s used to write "simple" texts? It can also be used to delete text ...  Do you have a fan in your computer that only makes noise at startup? !! IMPORTANT !! Actually useful ... It’s better to let it run a bit at startup - sic - You shouldn’t remove the menu with the timer = countdown = ventilation ...  See you+

Faites attention lorsque vous supprimez un système d'exploitation, vous risquez de supprimer un fichier de démarrage et après aucun des deux systèmes ne fonctionnera. J'ai eu ce problème et après, aucun de mes systèmes ne fonctionnait.

Hello,
I have a serious issue
Some time ago I had Windows ME and I just installed XP Home SP3
The XP installation went very well but when I start my PC it gives me the option to boot into ME or XP
So I would like a solution that would allow me to remove Windows Millennium from my hard drive so that my PC only boots into XP
Thank you for your help

Hello.

For me, the problem is:
I have Windows XP on the C: partition and I had Seven on the D: partition; now I've deleted Seven but not properly, I actually deleted it in Windows and now every time I start up, I get the following message: Choose the operating system to boot:
-Previous version (XP)
-Windows 7
So I’m looking for a solution to remove this Windows SEVEN.

P.S.: I can no longer boot from CD with my new CD containing my new operating system HELP!

I have the choice between Windows 7

except that on the first one I have my hard drive OS C
and on the second I have RECOVERY

how do we combine them into a single system?

Hello alexi84, please I would like to know how you managed to access boot.ini. Because I can't access this boot.ini file Thank you in advance.

zero1 · Answer

Hello. I think I have your solution.
When you start with the right system, you run msconfig and hit enter; this will open a system configuration window, then you go to the startup tab.

This way, you can see your 3 operating systems; it displays the one you are currently using, so you set that one as default. Then you remove the others, and that's it! ;).

For those using Vista or Seven (7), use the command prompt with the command "bcdedit", it's much easier! (instead of boot.ini)
