because at the part where you are doing partitioning and formatting of the drive, you're not at a point where your mouse is even working. What sort of disk were you using for the reinstallation? Was this an MS version of XP or a PC maker's recovery disk?
I was trying to reinstall windows xp and when the box at the bottom of the blue screen says (unpartitioned space) i clicked on it, instead of making a "partitioned space". Now the installation is all messed up. any advice?
