Windows 7: Deleting Ubuntu 9.04 Partition

Ok, for a while now, I've been dual booting Windows 7 and Ubuntu 9.04. However, now I just want to have Windows 7 and get rid of Ubuntu. How do I get rid of the partition while making sure Windows 7 will boot up normally? I know you have to go into Disk Management, delete the Ubuntu partitions and then extend the Windows 7 partition so that it takes up the entire hard drive again. After that, with the GRUB boot loader from Ubuntu gone, how do I make sure that Windows 7 will boot normally? I heard you can insert the Windows 7 Installation DVD and choose to repair your computer and then choose Startup Repair. However, could someone please confirm this? I don't want to end up doing a full install of Windows 7 again.

You are going perfect. No issues in your method.

I was afraid of this...it didn't work, meaning I can no longer boot into Windows 7. When I try to boot up, it says:

GRUB Loading Stage 1.5

GRUB Loading, Please wait...
ERROR 22

Luckily, I backed up all my files, so I can just do a clean reinstall. I don't like doing Repair Installations.

A startup repair with your 7 disc didn't work? Try it again before you do a clean install

EDIT: My birthday year...Post 1989!

I've tried it 5 times I think. It doesn't detect a problem. Even my brother down at Microsoft HQ doesn't know what's happening.

Start
Type in MSCONFIG
Go to boot
Click on Ubuntu
Hit delete
then delete ubuntu partition
Extend Windows 7's
Done!

I can't even boot into Windows 7 anymore, so I can't do this. Besides, I've already deleted and extended the partitions.

Where did you have GRUB installed? When I installed Ubuntu on a separate partition I installed GRUB also on that partition not on my primary OS partition and like that I can delete Ubuntu partition anytime without problems.

FDISK it with a dos boot disk?

boot from your seven disc and choose "repair".otherwise, just do a nice new clean install
