What is the best way to triple boot Windows 7 Home Premium, Windows 8 Professional RTM, and the latest version of Ubuntu? I already have Windows 7 and Windows 8 installed. I am currently downloading Ubuntu. I don't want to lose either of my OS's. Thanks for any help. :)

Here's how to do it:
Make sure it will not go beyond the 4 primary partitions, otherwise, your PC will not boot up.
You can make extra partitions with the Gparted tool, but it will not aloww more than 4 primary partitions, (more extended parititions are allowed )
After making the sufficient space for Windows 8 then
Install Windows 8
Now you notice that only Windows 7 and 8 are listed in Windows' boot loader
Now you have two options:
add Ubuntu in Windows' boot loader by using easyBCD
Reinstall grub 2 by with a live CD. to see video click here
After this if your windows in not listed in grub 2 then type
sudo update-grub2
Even if Windows is not listed retry after mounting your Windows drive
Have a look at this video for updating grub2
My machine also runs Windows 7, Windows 8 and Ubuntu 12.10. Ubuntu is one I installed the last, and GRUB2 automatically list all my other OS, so I don't have any boot problems.
But, if you want to use Windows 8 GUI bootloader, you can download EasyBCD and set it up from there. Windows 8 GUI bootloader boots Windows 8 faster (since it actually just a hybrid-boot), while selecting Windows 7 or Ubuntu (from the Windows 8 GUI bootloader) makes your computer restart and boot to your selected OS.
