Asuming you have the Vista DVD and the correct installation key... Put the DVD into the machine and restart or turn the machine on. It should try to boot fro the DVD drive. If it does not then you will have to go into the BIOS and set the boot order to DVD drive 1st.
There also may be a chance it is booting to a menu that asks you what you want to boot to. Choose DVD drive.
Try to use dvd cleaner disk to clean the lens, if it doesnot work, i think you have to replace your drive , this happens with Dell alot. but try to clean it, uninstall then install the driver back and check if its work.
If its a flat key make sure the things underneath the key are flat against the key and put it back on its spot and just press down on it until it clicks. You may need to press hard but please don't press too hard or you might do some damage.
I just got a dell inspiron 1720 and got a chunk of food under a key. And like you was not sure if the key was removable or not. well it was.. I GENTLY pulled it up and it poped off. It has very small groves that clip onto retaining wires.. very small and fragile looking. not saying yours is the same but if you can see under the key since it is up a little you may be able to tell... it was harder then I thought to put the key back on... pushed pretty hard and then POP it was on... If you dont feel comfortable doing it take it in. And like I said yours may not be the same as mine. if for some reason it is broke where it wont go back on, you should be able to order a new keyboard for it, IF you feel you can change one out.
