So when you delete the XP partition Win7 will not boot and you will blame Ubuntu. Just run the Win7 repairs from the Win7 disk in between the delete of the XP partition and the install of Ubuntu. Otherwise you will still have to run the repair of Win7 which overwrites grub and then you have to reinstall grub. Not the end of the world to reinstall grub there are many instructions on how to do and sometimes when we are reconfiguring our systems we do that anyway.
Ah ok, thanks for that.
I think I know what I'm doing now, marking thread as solved
