I have a hard disk that I would like to completely remove UBUNTU from. There is no other OS on it. UBUNTU is on all of the HD no unused partitions that I can see or other windows system here at all. I would like to completely remove UBUNTU and remove GRUB also. and be able to use this HDD for a windows system. Most of the threads I have read here in the forum relate to removing ubuntu from a dual OS HDD . There is talk of using partition magic or other utility to remove or change the partitions,but most of them are about a dual OS system, whereas I have an HDD with only ubuntu on it. Does UBUNTU have an uninstall program that I can download? Does partition magic remove the Ubuntu OS? Grub?

If you are going to install Windows then the Windows installer can do all of the work for you. The Windows installer will allow you to delete the current partitions, create new partitions, and install Windows. You don't have to do anything before running the Windows installer.

Just boot from the windows cd, windows will repartition the drive, and remove grub, and install its own bootmanager.
Another option is to boot from a linux live cd with gparted, and remove all partitions.
Here is an article from microsoft.

does not work. the computer wont allow the windows to format overthe UBUNTU

does not work. the computer wont allow boot from the windows cd. or allow the windows to format the HDD or run windows over the UBUNTU

So you mean that the windows cd won't boot?

Kind regards

You may need to enter the BIOS to set the "boot from CD" option to have priority over "boot from hard drive." During the BIOS check, most computers display something like "Press something-or-other for Setup." Press that before the BIOS check is over and you'll get into the BIOS settings.

My Dells display an option during the BIOS check to "select boot device."

Simplest solution: Boot into the Ubuntu, start a terminal (should be in the menu under Accessories or similar) and type You will be asked for your password, and you have to type it blind, so type carefully.Do this only, if the Ubuntu harddisk is the only one in your system. If you have more the one disk, you have to check which one is the one with the Ubuntu on it. This can be done with in a terminal. Then replace the sda in the command above with the one you found Ubunt on.
If you have done that, reboot and install Windows.
