Plz!!! need help with an HP Pavilion DV1000 Notebook

Well here is the problem. On an HP notebook my friend had started giving off the blue screen of death as many would call it, but since then have looked at it. I was able to save all their personal stuff by using Ubuntu by booting off of it as a live cd and transferring the files via USB Flash drive to a another computer.

However before all this I used an XP CD to install the operating system again by booting off the CD, but said there is no Hard Drive. However when I booted off Ubuntu and installed it the installation started working and Got Ubuntu on the HP Pavilion dv1000.

Though I wanted to ask if you or anyone would know of a site where I can learn the dos commands so I can format the drive to the NTFS File System.

Here are a couple things I found. The first may need a bootabe Floppy. The second looks interesting but you have to register at Tech Republic but it says it's free. Not sure what being 17 has to do with this, as far as I know formatting isn't like voting or drinking, i.e., you have to be of legal age. Be aware that when you're using DOS everything must be precisely entered, spaces, slashes, or whatever. So if it doesn't work the first time, keep trying
