I have successfully set up a a win7,win8 and Ubuntu 12.10 system. Windows 8 and Ubuntu are located on the same SSD, while windows 7 is located on another SSD. All went great and I can continue playing around with all 3 OS's. My only annoyance is, while restarting, windows 7 boot loader runs first. If I select ubuntu in the win7 manager it then runs grub2 and asks me to select an os. I used easy bcd to add entries into win8's boot manager and was hoping to just use that one. I installed ubuntu's loader on to its own partition. Any suggestions to just use Win8 loader and still be able to choose between all 3?
Figured this one out myself. The problem was in settings for easybcd and grub. I achieved my goal by "hiding" the grub boot menu from within Ubuntu. Also, when editing entries in easybcd, I checked the "skip boot menu" option. I restarted and it booted straight to the pretty blue Win 8 boot menu.
