Triple Booting Vista, XP and Ubuntu???

Ok, here is the problem that I'm faced with. I have Vista preinstalled on my Inspiron 1520, I have a non-bootable XP disc and I have the Ubuntu 7.04 Live CD. I want to triple boot my system, without having to worry about the self destruct Dell Media Direct button. I went through the threads here, and I've understood how to get through the problem in-case of a dual boot. But I still don't know if it'll work with my non-bootable XP disc. Though I might manage to get my hands on a bootable XP disc, I'm not sure how to get Media Direct to work on Ubuntu(or even disable the button without going for the Russian method). Please Help if you know how to proceed.
Regards

 

Install XP first from a freshly wiped hard drive, if it is a real copy of windows it should be recognized and will be able to boot from it. Then install your Vista copy on top of XP. It will ask you if you want to replace the old OS or install Vista along side the other OS using a duel boot.

Next you need to boot up on your Ubuntu Live CD that you have, and go to System -> Administration -> Gnome Partition Editor. You need to add two new partitions for Ubuntu to install correctly. The first should be a minimum of 3GB and formatted using the EXT3 file system. The second partition is your Linux swap, which should be about 1GB.

Once you've got your partitions set up you just follow the regular Ubuntu installation. Hope this helps.

 

Wouldn't that method cause conflict with Dell Media Direct?

Does Dell provide an actual bootable Vista OS or a a backup image recovery disc (as is the case with most budget laptops)?

 

thanks, but I think there will be a few problems with that, like what techNOguy has pointed out, firstly I only have a vista recovery disk, then I think there will be some problems with the Dell Media Direct button, finally I feel that my copy of windows XP is not legitimate, because I paid only 800Rs for it, that translates to 20$.
Any more answers would be really helpful.
