I have recently installed Windows 7 on my new Vertex 3 240 GB SSD. However, my old Windows installation is haunting me as I am unable to delete the files, and it appears in boot menu.
Now, I am not a super dummy. I have disabled the boot menu so it does not irritate me, but I still don't like the fact that there are 2 Windows installations in the boot menu, because I have a feeling it slows down the startup slightly.
Another problem I am facing is that I can't seem to be able to remove some of the old files. I have set myself as the owner of the files (recursively), and given myself Full Permissions, and yet it says I have no access to delete those files.
How do I get rid of my old Windows installation entirely?
