Okay, so here it goes. I have two hard drives. One is a 1TB drive that I have Win 7 on, the other is a 250GB that I have Ubuntu on. Both installs work fine, neither is corrupted. I installed Win 7 Ultimate first because I know it screws up grub on a system with Ubuntu installed first. Then after I got it pretty much totally set up, I restarted because of updates. Then, with it restarting, I installed Ubuntu on the other drive by letting it install what it needed automatically. When I restarted, it went to grub, of course. However, that's when I noticed the problem. There was no entry for Windows. I restarted onto the Boot Repair live disk (results at http://paste.ubuntu.com/8405452) but it seems to have cloned the failed grub from the other disk to the Windows hard drive, as that one only sees Ubuntu as well.

How do I completely remove grub and then install it as fresh? I have the grub 2 disk as well as all install media I need for any of the operating systems I have installed.
