Note Snow Leopard 10.6 Chameleon / Boot-132

Multiboot on same drive

I have installed snow leopard with chameleon rc3 and PC-EFI 10.3. I would like to install windows 7 on the same hard drive in a new partition. But when i do so it overwrites the Chameleon bootloader and only windows boots. Can someone help…

How did you install Chameleon initially? Just reinstall it to your SL boot partition?

Field Note #2 @xlucian 2009-10-08

if you have Chameleon installed on the snow partition, use Diskpart in windows. if you don't no how...

PS: i have dual boot on same hdd , diff partitions with win7 and leo...but chameleon is installed on an usb stick with the needed extra folder and it's set from bios to boot the usb stick first.

open a commander terminal (win+r...type cmd...hit enter) and type:
->diskpart
->list disk
! if you have more than one hdd select the hdd on with is installed snow
->select disk $
! $ is the number of your disk, i have disk 0 and 1...in my case is select disk 0
->list partition
->select partition &
! & is the number of your snow partition
->active
! if it says that "active" is not recognized type "set active"

now reboot and you should be able to select snow or win
