I have Vista and XP and Knoppix all on different drives as of now I've been booting from the BIOS but it's getting tedious is there a way to show all of them ?

my main drive is Vista
my secondary is XP
and my third is Knoppix

so Vista loads first and I want to show all of the OSes in the boot menu but I don't know how I know the Knoppix may be a little harder to do so I'm really focusing on XP now after all Knoppix was made to run from CD but I can't find any other linux that I like as much.

right click on my computer on desktop and go to properties then advanced tab then startup and recovery settings in the new window tick time to display list of operating systems then that should solve your problem

Try GAG.

I tried to use BCDeasy and VistaBootPro and nothing it shows up in the boot screen and when I click it it shows a white progress bar but then it does nothing.

You can try to edit the Boot.ini of windows as seen here:

But I doubt it will include your Linux. But worth a try.

Again I would suggest GAG which can be run from a floppy as well as being installed to the hard drive.
