So, I have a Toshiba Satelite laptop that came with Vista.  I hate
Vista, so I bought a new copy of XP to install on my computer.  I
partitioned the drive (like I read on a board) and my laptop will
STILL not let me install XP.  I was told Toshiba has made it so you
can't do that.  So I figure F#@! it - I'll keep Vista till the
updates fix it (in 6 years.)  

So, now how do i "unpartition" my computer?

Thanks for any help.  I hope this is as easy at it was to partition
it.
