Right, so I needed some software for work that just wasn't available on Ubuntu so I had to install Windows 7. Now, I installed Windows 7 on a separate partition from Ubuntu, but now when I start my computer it automatically starts up Windows without even letting me choose to boot up in Ubuntu. Also, the old partition that Ubuntu was installed on doesn't show up on My Computer, only the new one does, but with the original size (i.e. a 300 GB HD, partitioned into 2x150 GB; the Windows partition is still 150 GB with all the other files on it intact).
I luckily had all my files on the Windows partition, but I find it a bit odd that the old partition would've just disappeared like that... thoughts?
