I have windows 2000, then I installed xp and now have both os when I start up.How do I uninstall 2000? I've read some posts and am not clear on what u mean by formatting. I'm not very experience and need help. Thank you .

Fisrt of you want to make sure that all the DATA that you want to keep is backed up, off the hard drive.
Make sure you have ALL your apps and XP discs to hand.


Once all this is done you are ready to reinstall XP.
This is very simple:
Here's some instructions that should help:
*Look for message "booting from CD" usually located at the bottom of the screen. If you have a factory splash screen, press ESC to unload it.
*Press any Key when you see the prompt to 'Press Any Key"
*Setup will start copying files, if you need to install any third-party or RAID drivers press F6 at this time. The copying of files can take awhile.(leave this one)
*Next you will get the option to repair or enter setup, choose to enter setup. Press ENTER.
*Press F8 if you agree to the license.
*Setup will scan for previous Windows installations
*You want to delete all existing partitions, recreate the ones you want and then install a fresh copy of XP.

Leave to cook for 30-40 minutes

This will completely wipe your drive (Format) and reinstall ONE copy of XP.

The reinstall route I always use is:
Install XP
FULLY patch it with Windows Update
Install Anti Virus, update and scan (AVG is good and free)
Install Anti spyware, update and scan (A couple of good removal tools are Spybot and Adaware)
Defrag.

Then install any other Apps you need, like Office, etc.

Hope this helps

To remove the other operatimg system you right click my computer go to properties then advanced tab then got o settings under startup and recovery, go to edit and remove the operating system u want to get rid of

Thanks but no thanks because I don't want to reinstall I just want to clear operating system choice message. Like I said I have already removed the boot.ini
For the other operating system.
