I've searched the posts and can't find the exact answer I need. I've installed Ubuntu to my hard drive completely, and wiped my Windows 7. I do not want Ubuntu anymore; I want Windows 7 back. But when I put in my CD to reinstall Windows 7, it said my disk partition needed to be in ntfs format. I can't format my drive from here, but I can delete it, although I don't know what that would do. The other partition I have is my system recovery partition. So how do remove this partition?

I think you're in the wrong place ... you need the "Ask Windows" community :) – Dave Child Sep 2 '11 at 14:14

I'm pretty sure Windows installer has an option to delete partitions/use entire disk/something similar, though the last time I used it it was WinXP, not Win7.

At any rate, it's not a problem for Ubuntu to be concerned with, it's a problem/defect of the Windows installer :)

However, if you boot from Ubuntu live CD, you should be able to delete the Ubuntu partition and you also may be able to create a new partition and assign it NTFS partition ID.

Just to clarify: partitions have an "ID" attribute, so if you created a partition for Ubuntu, it's ID will be 83, which is "Linux". You can not just format this partition to NTFS - you need to delete it and create a new one with different ID.

Obviously, all data will be lost, so make a backup.

Use the delete option. It will remove that partition and allow you to install Windows again, if that is what you want.

Using the Ubuntu installation disk, you can format the drive to ntfs.

First, open the gparted application.

Next, right click on each of the partitions listed one by one and select delete to delete each one until you have nothing but free space listed.

Then, right click on the "free space" select "new" and select partition type "primary" and set the format type to "NTFS".

Finally, click on the green check-mark to apply the changes, this may take a little while so be patient.

When you are done, exit out of Ubuntu, eject the Ubuntu disk and replace it with the Windows installation disk and you'll be good to go.
