Hey Guys,

 

Long time no post. I followed Prasys's guide to installing Snow Leopard the long way. Anyways I have Snow Leopard Retail installed on a USB 2.0 Hard Drive with 3 (4) Partitions. Here is the output when I /> diskutil list:

 

0: GUID_partition_scheme *320.1 GB disk0

1: EFI 209.7 MB disk0s1

2: Apple_HFS Snow Leopard 143.7 GB disk0s2

3: Apple_HFS Backup 143.7 GB disk0s3

4: Apple_HFS Install 32.1 GB disk0s4

 

 

I have Snow Leopard 10.6.1 installed on the Snow Leopard partition (disk0s2) and it works PURRFECT on my Dell XPS 420 w/ Chameleon 2.0 RC1 and PC EFI 10.1. I haven't installed the SATA drivers because I have Windows 7 running off the Internal SATA drive which I don't want to mess with. Well anyways Snow Leopard works PERFECT until I use bios to boot into my other drive or until I disconnect my USB drive through a power cycle. What happens after that is a total mystery to me. My Bios/Computer will not see the USB drive as having a active bootable partition or MBR(GUID) even though I know its there!

 

The one and only way I have figured out on how to fix this is by doing these steps exactly on my MBP. I will start up my MBP and go to System Preferences, then Startup Disks. I will then select Mac OSX 10.6.1 on Snow Leopard as my Startup Disk. I will restart and it will boot into that OS perfectly using my Apple MacBook Pro. I will then shut down and disconnect the USB drive from my MBP and connect it to my Dell XPS 420. I fire up my XPS and Viola! My BIOS reads that partition correctly and Chameleon gives me the option of booting from Snow Leopard.

 

Now here are a few things;

 

Chameleon is installed on disk0s2 and so is my Snow Leopard.

Backup is my Time Machine Backup

Install is my Retail DVD with proper kexts.

 

I tried blessing the usb drive partition holding Chameleon and OSX but to no avail. Maybe I am doing something wrong? Or Maybe when I select the startup disk on my actual Mac it does something I don't know about.

 

Any help or questions to help fix this issue would be greatly appreciated. I tried greatly to search for a similar topic but could not find such an issue anywhere even GOOGLE.
