Windows 7: How do I remove Ubuntu rfom HDD without doing complete re-install?

I have installed ubuntu onto the same HDD as windows, and I no longer want it. I have tried to just format the partition that it is on but when I do that I cannot load windows, as it looks for the 'grub'. I think what it is is that Ubuntu is the primary OS, I can't even alter the boot first options.

Is there a way I can remove this Os without having to do a complete re-install of windows?

just delete the partition in which u have installed the ubuntu.... i hope u know how....
still m telling...
rt click on my computer icon and select manage and then go to the disk management page. from here u can del the ubuntu partion and then afterwards u just insert ur win 7 dvd n boot n format the partitions u want to n do a clean install of win 7..

You can try this: MBR - Restore Windows 7 Master Boot Record

If you read my post you will see that I dont want to do a clean install if windows.

I got windows working again by re installing ubuntu.

The procedure is to wipe the partition containing GRUB as it may interfere with Windows 7 if any of it's code remains with a simple formatting. Use free Partition Wizard bootable CD to Wipe Ubuntu partition with zeros then Modify>Set to Active the Windows 7 partition. You can also use PW to resize Windows 7 into the deleted space or repartition any way you like.

Windows 7 will not now start if GRUB was used to manage boot. So you need to boot your Windows 7 DVD Repair console or Repair CD, click through to Recovery Tools list to run Startup Repair up to 3 separate times with reboots to write the MBR to Windows 7, which will work if it is marked Active.

Startup Repair
