You absolutely do not want to have XP on an SSD. XP does not support Trim and you will lose a lot of the SSD performance advantage if you let XP manipulate the SSD. Put it on a spinning disk (disconnect the SSD during the installation) and switch between the 2 systems with the bootorder of the BIOS. But do not let XP near the SSD.
But if you insist to do that odd configuration, post a picture of Disk Management and I will see whether I can figure out what your problem is. Not sure what you mean by "Green" partition. Are you talking about free space or a dynamic partition. If it is the latter, you are in real trouble.
