I have FC3 installed on on HD and XP on a separate HD. What program can anyone recommend that will give me the opition of booting from either HD at start up.

Well, I only use lilo as a boot manager these days, and grub is much the same. There are others out there, but I see no reason to go beyond lilo or grub for a simple dual boot. But in a dual boot you must install the OS's correctly, XP first and then FC3 on the next drive second. That's the easy way.

Edit: Some bios's will have options to let you boot either drive also...

thanks for the info

Yes the recommended thing is installing first winXP and after that installing your linux distro (or distros)... But if you want your windows installed on the fifth partition (/dev/hda5) , there is no problem.. It just won't configure the boot manager automatically.. this is my case.. I also thought win should be on the first partition, just made some tests and changed some settings of the boot manager, an it worked fine..

I don't like the idea of win as a primary OS..

I wonder.. doesn't FC3 install a boot manager during the installation of the distro?
if not, let me now..
because it should have been installed already...
