easiest way i found was download and burn the livecd of gparted.  boot from that and it'll let you change the active partition.

You can use your OSX install DVD: http://forum.insanel...showtopic=22844

I found this solution, works great for me...

start into windows,
open DOS-Box
Start with (type at the prompt) diskpart (Enter)

" Text in Quotes "xxx..."  is only an explaination, not type this!

select - select the item e.g. disk or partition
active - set the selected partition as active.

End of explaination."

select disk 0 (Enter) "in order you have ONLY ONE HDD"
select partition 0 or 1 (Enter) "where you have OSx86 installed"
active (Enter) " set the choosen partition to active"

Thats it. Very easy. Hope that can help you...

Try clicking Start -> Run then type: diskpart

[anantha11]

yea i tried that but still no luck the only thing that actually reads the drive[apart from the osx install disc] is gparted but i get an error on the partition it says that:
'Incorrect magic value journal header'
and one more thing i am installing it on a partition in an extended partition, could this be the problem if so how do i just make it 3 logical partitions.

What are you using as your Boot Loader? Could try using WinGrub and then setting the OS X entry as active.

Gparted should work, i've used it many times to set OSX partition as active.
