Problems removing Ubuntu

[ChakaZulu]

Hi, I have made a few posts about errors that I get with Ubuntu not loading and always dropping to a shell with (initramfs). Now I want to just remove Ubuntu from my system, which also has Vista. I thought I could just reformat the partition that Ubuntu is on but when I did that, the computer won't boot at all. I think because the Grub bootloader is in the same partition as Vista so it looks for that first? Not sure but to get around this I reinstalled Ubuntu so I could get back into Vista. Any suggestions on how I can completely remove Ubuntu and not have any issues? Do I have to reformat the Vista partition as well? Thanks.
-would be great if Ubuntu would just work on my computer :(

Do you have windows bootable CD that you can boot your machine with? If not, you can use Super GRUB Disk to remove GRUB from MBR.

Also you could use the recovery console.Do a Google search for Remove Grub from Vista.
