Remove dual-boot Windows 7+7

[lopdog]

Hi!

I'm currently running Windows 7 Profesional, and a few months ago I installed a second version of Windows 7 (Ultimate) for testing purposes. Now I want to remove the last version I installed, and go back to only Windows 7 pro. How can I do this without messing up the boot process, since the last version I installed took control of this?

If my memory serves me right I don't think you can. I may be wrong but you may have to format and reinstall Windows 7 Pro.

The problem is that I want to avoid re-install, since I have a lot of programs installed and configured. Would it be possible to remove the new (windows 7 ultimate) partition, and use the Windows 7 DVD to repair the boot sector?

I remember seeing a 'Repair Master Boot Record' option when I latest used a Vista recovery DVD. You should check your recovery DVD for this option, and if it's there, you'd be pretty much set for removing the partition.

Now, I have not done this personally, but it sounds theoretically possible. Thus I'd prefer to be without blame if something happens any way .

When I latest did this with a dual-boot Ubuntu vs. Windows 7, I crashed it to smitherenes, and had to re-install BOTH operating systems. Luckily, I made an extensive backup on both OS' files. I suggest you backup everything important before proceeding.

That was not because of a Repair MBR option, but because I ******* up GRUB (sort-of Linux's bootloader) btw.

Delete the testing partition, and then insert your Windows CD, select your language and click next, then "Repair your Computer" option, and the option along the lines of automatic repair.

You can also manually do it with the following guide (via command prompt): http://www.sevenforums.com/tutorials/20864-mbr-restore-windows-7-master-boot-record.html

Automatic repair worked perfectly, it took me 5 minutes. Thank you.
