Ok, I've been trying to reformat my laptop for two days now. Compaq Presario, running windows xp. I have my restore disk (Application and Driver Recovery DVD), and I went into the bios and changed the boot order to cd rom first. It doesn't give me any options, just boots to windows like normal. For some reason, the option to go to restart: restart in Ms-dos mode is not there. I tried using the command prompt, but it gives me some jibber jabber about this volume is in use by another process (presumebly windows, since I cannot exit into DOS). I even tried downloading Maxblast, but it won't let me format it because it is my windows drive. I've read every tutorial I can find and nothing has worked. My eternal gratitude to anyone who can offer up a working solution.
