Hi EYacoub, welcome to NeoSmart Technologies.

Sorry for the late reply, had to brush-up on my OS X EFI skills :smile:

Give this a shot:
EasyBCD | Useful Utilities | Power Console
Code:
cd bin
bcdedit /set {956a8b99-3185-11dc-86a2-0019e3f947ef} device boot

Please let me know if that does the trick - I'll change EasyBCD to do that automatically in that case.
 
unfortunitly it did not work i still cant boot in to osx with the vista bootloader andi still have to hold down the optiion key to get it to go to vista and unfortunatly when i start easy bcd now it cant find the boot drive and when i try to select it it tells me that it dose not exisst would it be prudent to ininstall and reinstall it maybe witht he new beta

Please don't triple-post.

I'd recommend booting OS X with the normal boot process. Use bootcamp to load the Vista bootloader and from there launch Linux, Vista, XP, etc. via EasyBCD.

Apple's closed API and lack of documentation make it absoloutely impossible for us to really have any clue WTF happens in boot.efi (and people say Microsoft is bad!) - I really don't know what to say if boot.efi doesn't load for you.
 
Thanks alot will try that next i am working on another mac trying to install vista first then osx and see if i can get vista as the primary os
 
Good luck.

Just to double-check, you did rename boot.efi to nst_mac.efi when you copied it to C:\NST\, right?
 
yes like 3 times and i am still trying to get it to work i have vista booting first and the boot menu comming up just not loadding osx
 
Yeah, if that doesn't work, I really don't know what to say. EasyBCD executes steps that have been used on several guides and websites whose authors and users say they work. We've had some people have success with these scenarios as well.

However, I don't have a Macintel myself and, as such, am not in a positition to see what is going wrong.
