Okay, I installed Ubuntu, and had it create GRUB on the Ubuntu partition, and it worked fine. Now I need to add an entry in the boot manager for GRUB. I tried using EasyBCD to add the entry, but I have had no luck with the program. It likes to mess up all my entries, forcing me to run a Startup Repair and eventually resorting to using BCD Edit to manually configure the boot loader. I looked through the tutorials for bcdedit, but I have not figured out how to add an entry. Can someone clue me in?
