Dual boot on UEFI system with 2 discs, GPT and MBR

Hi,I cannot find the answer to my problem so I am hoping someone here will have the answer. I have just built my new PC with a UEFI bios and have W8 running on an SSD that is set up as GPT. I have now put in my old HDD from my old PC that has W8.1 RTM on the first partition but is set us as MBR for my old BIOS. Can I dul boot to this easily with EasyBCD - so far when I select the 8.1 installation the PC stops, then boots up again but back to the black boot menu, round in circles. A ny ideas gratefully recieved. Dave. :wtf:

Aside from the conflict between MBR and EFI, you can't just take a hard drive from another system and plug it into a new one and pray for the best.
With Windows XP, the option of performing an in-place upgrade (aka repair install) could be used in such a scenario to migrate your installation to a new machine, however that option is no longer available with Windows Vista/7/8.
