Trouble with windows installer, Windows installer error Options

[Purk81]

when i turn on my computer, right after the desktop is visible, the first thing i see is a windows installer pop up preparing installation. I click cancel. It comes back about 2 times. Then it shows a window titled "photo gallery". It will show info that says: "the feature you are trying to use is on a cd-rom or other removeable disk that is not available. Insert the 'photo gallery' disk and click ok. use source 1, shows up in a field at the bottom. and i could not make sense of it at all. So,I click cancel. can anyone hep me with this. Thanks
