Installing 3rd OS
 

I currently have Windows XP and fedora 9 .
I wanted to try Open Solaris .
can i have all three running at the same time ?
Wont there be a clash between grub loaders ?

You can have multiple operating systems installed, but can only have one actually running at a time (unless you're using some kind of virtualisation software). You need not worry about bootloaders either: you can just allow OpenSolaris to install GRUB to the master boot record (MBR) of your disk and hopefully it will detect Fedora and add an entry for it (if not, you can do this by hand, obviously). Presumably OpenSolaris' install procedure allows you to skip bootloader installation, so if you did that, you'd have to add an entry for it to your existing GRUB config (under Fedora).
