How to Uninstall Ubuntu Linux from a Dual Boot System with BootIt NG

You need to be in windows, (this is an .exe) and download this file http://www.terabyteunlimited.com/bootitng.html BootIt Next Generation.This program does cost money however, obtaining a free utility has been elusive. Also this is NOT the only software that can perform this task. There are a large variety of programs you can purchase that will perform this function.

When downloaded, run the setup.

Make a bootable floppy or CD, either choice works. (The CD option makes a cd .iso image so you will need a program to burn it to the cd.) Note:- If your system doesn't show screen while booting, Choose other video option available from the settings. Create ISO and burn CD again with new video driver. Using Re-writable cd will be a good option, in case you need to burn CD's again.

Next you will restart your computer with the cd or floppy in the drive. Once you boot into the program do not install it to your HDD.

Click cancel to run the program from your cd or floppy.

Go to partition work. Click the oval on the left side of the window (yes you can use your mouse!) to go to your primary HDD.

Select and delete every partition except for your standard windows partition. Now you should have a format-less partition that says free space after it.

Select your windows partition and click resize. The program will run an error check which may take a while depending on your partition size.

Type in the largest size in the prompt unless you have other plans for some of that space. Once you do that the program will allocate all that space back to your primary partition.

If you installed grub the bootloader, you will need to reset your MBR (master boot record) or else you can't boot up because grub will crash. Select your windows partition

Go to view MBR on the left.

Select your windows partition and click STD MBR. This will remove grub and set your MBR back to its original state.

Click apply and the changes will take effect.
