Dual boot easy question - Carry on or start again?

Edited my long post as no response.

Can I install Windows 7 AFTER I have installed Leopard, or will it mess up the bootloader?

Partition 1: empty
Partition 2: iDeneb Leopard install, working

any help much appreciated.

Thx

started again, messed up bootloader. So thanks for the heads up. :fail

I installed win7 after installing iPC 10.5.6 distro, and yes it did screw up the bootloader. It seems to have changed my OSX partition so its not active anymore. On one of my older dells that had IDE drives, i could solve the bootloader problem but using the BIOS boot option, which allowed me choose which physical drive to boot.

However, on my most recent install on a friends asus AMD motherboard, he didnt have that option so we had to fix this. When i boot up, it goes right into windows 7 (windows7 was installed after iPC OSX86) without showing the Chameleon bootloader with options to choose. After much frustration, I found the problem was OSX wasn't active anymore. The solution was to boot up using the iPC install dvd, this allowed me to get into my OSX install (or you can just boot into the install dvd, open terminal from top menu). Go to terminal and follow the instructions here by Rammjet to set your OSX partition active again

[How to] Setting Your Partition "Active" Using Fdisk in MacOSX - InsanelyMac Forum

I always make the first partition (top partition in disk utility) my OSX partition and have the drive plugged into the first sata port so the disk location is disk0s1. you need to know your exact location of the disk number and partition number to correctly set it active.

after completing this, my bootloader magically appeared again, and now i'm dual booting win7 with iPC OSX 10.5.6 with ease

hope this helps
