I have a few hard drives that I installed operating systems on at different times on the same computer. How can I set up a boot menu so I can see all the os's to boot from? I know there is a text file in the main os, windows xp pro, and it does show two of the three hard drives. I don't know how to add the third one to the boot menu since you need to have some special numbers before the location of the drive and the name. I'd prefer to do it manually instead of by some sort of program, but if thats the only route, thats what i'll have to do.
