How can I remove the dual boot menu - clear MBR?

I have two operation systems running on my PC. Windows on one hard disk and Linux on another. I'd like to uninstall Linux (to reinstall it differently.) I'd like to remove the boot menu which loads at startup. I believe it is within the MBR. How do I do this?

You can boot from your Windows XP CD.

Type R to start the Recovery Console when prompted.

Select your Windows installation when prompted.

Login as Administrator.

Type "fixmbr". This will remake your Master Boot Record without the Linux bits.

(Strongly recomment you backup you files first - better still if possible image your whole PC.)

I have to assume you're running Windows XP. FIRST, create a system restore point, then......click on the start button and then click on RUN. In the open window, type in MSCONFIG and click on OK. Click on BOOT.INI and you should be able to see BOTH operating systems. Very carefully delete the non XP os and close....and reboot.
