I can't get it to switch back leopard, if I hit alt enter nothing, it used to work, if I shut down windows, macbookpro just acts like it is turned off, if I power it back up it boots xp, I tried pulling battery out, and removing power cord, but it keeps booting xp, cant get back to leopard.
You're running Boot Camp, meaning, you booted your mac into Windows, Parallels is not running, in the Windows tray there's a grey icon shaped like a square, double click on it and select 'Start Up Disk' and Macintosh HD (or similar), then shut down Windows and reboot. I suggest you read Boot Camp's Manual.
