Everything means anything you want to save. You will lose everything on the computer. MP3s, movies, programs, love letters, anything and everything.

My computer came with a CD that has all the drivers on it. Of course, I bought it from Dell. I guess I don't know your situation in that regard.

EDIT: Go <a href="http://bootdisk.com/bootdisk.htm">here</a> to make a bootdisk. You'll need it. Click on Windows ME and download the file to your computer. Click on it and follow the directions. You will need a formatted floppy disk for this. PS. it doesn't matter if you use WinXP.
