Dual Boot WIN7 & Snow Leo

What I did (the last time, LOL):
partitioned as GPT (200MB EFI + 800GB OS X + 200 (well, 1980 or whatever) W7) and installed OS X.
from OS X I ran a copy of boot camp that I got from I don't know where that run's on hackintoshes (it doesn't ask to update the EFI). You may be able to skip this, but sometimes the W7 installer would growl at me if it saw the partition table as "pure GPT", so I think that the BootCamp partitioner not only partitions but updates/creates the protective MBR of GPT (in other words: it makes W7 think it's MBR, I think...).
Installed W7
Installed tonymac's Dr. Hurt RC5 pre 8 installer package.

you need you windows 7 install dvd
boot it. set windows 7 partition to active

1. After the language select screen, choose "Repair your computer" from the lower left
2. The system will not find any installations. This is okay, click the top radio button and hit Next
3. You'll see a list of "System Recovery Options". Open up the Command Prompt
4. Try typing the following commands in order: "bootrec /fixmbr", "bootrec /fixboot", "bootrec /rebuildbdc". If these complete successfully, go ahead and skip the next step. However, if any of these steps reports "Element cannot be found" you need to reconfigure the disk configuration.
5. You're going to use DISKPART to make the Win7 partition active. You can type "HELP" for a list of commands or check out Microsoft's help page (support.micro soft.com/kb/300415). Basically you select the drive first ("LIST DRIVES" and then "SELECT DRIVE [number]") and then the partition ("LIST PARTITION" and then "SELECT PARTITION [number]") where Win7 is installed. Then type "ACTIVE" to make the selected partition active. Once this is finished, repeat the previous step.
6. With the bootloader now created, we need to let Win7 configure it. Restart and boot from the DVD again, and choose the same repair option as before. Now you should see your Win7 installation listed. Allow the installer to repair the system. You may have to repeat this step once or twice, but eventually the bootloader will be fixed and your machine will work again!

once win7 bootloader is repaired, set osx partition to active, and when booting windows 7 select it from cham's menu

I followed the guide from here:

osx86.soju garden.com/category/working-with-os-x/

This was because both my Mac OSX and Win7 partition are on the MBR-partition scheme.

The only difference from the directions was I set Mac OSX active using Win7 diskpart, and not in MacOS terminal. Win7 gets confused if you do it through Mac OSX. You have to repeat it several times (first set Win7 active), then boot into Win7 using the disc, and then set your Mac OS partition active.
