Dual Booting Win 7 and Mac OS X 10.6

Hi everybody, just last night I installed Mac OS X 10.6 on my PC.

To start off I already had Windows 7 installed.

I partitioned a 20GB section on my hard drive to be set aside to install Mac OS on to it ( G: )

I loaded the Mac OS X install CD.

I succsesfully installed Mac to the partition.

I loaded back in to Windows 7, open EasyBCD 2.0. Added an entriy

Mac Tab --> Name: Mac OS X --> Mode: MBR. --> Add Entry.

I rebooted the computer, Boot menu loaded displaying Windows 7 and Mac OS X

I selected Mac OS X, the screen instantly went into a error message saying:

Missing or Corrupt file: NST\nst_mac.mbr
Error: 000X001X0 <--(Something like that, it was a bunch of 0's and X's)

I can't seem to figure out why im getting this error message.

My BCD log is as follows:

There are a total of 2 entries listed in the bootloader.

Default: Microsoft Windows 7
Timeout: 5 seconds
Boot Drive: C:\

Entry #1
Name: Microsoft Windows 7
BCD ID: {default}

Bootloader Path: \Windows\system32\winload.exe

Entry #2

BCD ID: {2e4fded9-dfca-11df-9ca4-c72f462822ab}

Hi Dale,

Is there a file C:\NST\nst_mac.mbr on your PC?
Yes there is. I checked that a little while ago. At first it wasnt there, there was just an .iso file named "nst_mac" now there is the .iso file and a file named "nst_mac.mbr" the file is 1KB in size. Does that sound right?


Ok, well I went and restarted my comp. Now when I selcet Mac OS X, a black page comes up and at the very top is says "CHAIN BOOTING EROOR"


Another Update: I downloaded EasyBCD 2.0.3 beta. I delted Mac entry, added Mac entry back set to mode: Efi (Default). I restarted my comp. Boot screen appered. I selected Mac OS X, and Vwaalaaa, it worked. The camelon thing appered at the top of the screen, and it said press any key to boot Mac OS X 10.6. I hit a key. The gray/whitesh screen with the Apple logo appered, in other words the Mac boot screen. I waited 3 mins, no responce. It frezzes, what do I do know?? Im going to reboot and boot Mac again, this time ill wait 10mins, and if nothing responds ill be sure to let you know. Mean while is there a fix for this im missing?


No go. I rebooted to Mac, apple screen came up. I waited 10mins. Nothing. Any ideas?
