thnx alot cubsgal.. waiting for your response

Howdy sportsggek,
Will have you a step by step tutorial just for you by morning. Im in a small place right now and dont want to wake the kids. But I promise to get one up for ya.

Ok I am going to assume you know how to partition hard drives etc.. If not let me know..
What your going to have to do is figure out which hard drive you want XP on and the other 2 os's on.
Your going to want to install XP first but to let Linux see some of that hard drive space, you will have to format it in FAT 32. Not NTFS. So you would have to partition the HD in parts smaller than 32 gb. Install XP

Next your going to want to either disable the hard drive that has XP on it or on the even safer side take the hard drive out.(gets tricky when you put 3 os's on there)

Now install Windows 2003 first on the second HD again you have to use FAT32. Once that is all done go staright to installing Fedora, it will automaticlly partition a page file for you and where Fedora will be.

Now connect all the hard drives back up and bootup.

Next when your going to want to boot into 2003 since fedora will put the Boot.ini in for you but not XP's Yet. Open the boot .ini file and paste this into there Either on top or on the bottom wont matter.

[operating systems]
multi(0)disk(0)rdisk(0)partition(2)\WINDOWS="Micro soft Windows XP Home Edition" /noexecute=optin /fastdetect

If you have XP pro type in PRO after Microsoft Windows XP

Now your ready to have those three see one another. exept Fedora will not see Windows as you probly know.

If you need any more help just let us know.
