The toshiba laptop has Win 7 Home Edition. I resized the partition (shrink). I made two other partitions to install two Win XP SP3. Trying to have 1x Win7, 2x WinXP, when resized the partition, i made sure Win 7 is still working. Then i installed one WinXP. then the other. Now at the boot Menu I only see two Win XP, my Windows 7 disappeared. But when I boot into Win XP i can still see C: with the Win 7 on it. It just wont show up in the boot menu.
