Partition El Capitan 10.11.4 to install Snow Leopard on the other partition half

[Esppse]

Hey Ive been trying to boot the Snow Leopard CD and it doesnt seem to be working. Does anyone know how to get a Snow Leopard partition running, while the original partition is El Capitan? I have a 2009 Mac Pro that has been upgraded to 2x 6 Core 3.46 Processor, 64 gb ram.

What exactly does not seem to be working ?

Its the white one with the lion on it. What I have is also an IMac. It has 10.6.2. And Im trying to transplant everything from that IMac to my Mac Pro (all my recording software and files.) When I hold C during bootup, it gets stuck on the Apple logo. I am also trying to execute the dmg from the desktop but it give me:

You can’t use this version of the application “Install Mac OS X” with this version of OS*X. You have “Install Mac OS X” 23.1.1.

I need to get Snow leopard on here before I migrate everything right? Because my Pro Tools 10 recording software only works on the older Mac OS X, and not with Capitan.

Thanks!

If you have the White DVD with a Lion on, it is not Snow Leopard.
All very confusing .

Oh I just realized El Capitan is free. Should I just wipe the hard drive and start over? And if I need a new OSX, maybe reinstall down the road? Id prefer to have 2 partitions though.

oh it is actually a Snow Leopard, i couldnt tell the difference between the two cats lol

If you have a Mac Pro, pop another drive into Bay 2, format Mac OS Extended (Jourballed) and install Snow Leopard on that.

The mac was delivered with a GREY disc with th OS on it (2009: Leopard or SnowLeopard). You need that one when starting up with only that original OS. Then you can upgrade to SnowLeopard with the white disc.

If I am understanding what you are saying correctly that is not entirely accurate/true. If you are using one of the gray discs you need the one for that specific model. That part is true. But you could also start up with the retail Leopard disc (black I think) or the retail Snow Leopard disc.

I said "You need that one when starting up with only that original OS." I meant it to understood: "if you want to install it as only OSX and starting up with it as only OSX". Sorry if it was not clear to you.

Now I'm really not sure what you mean. I've had dual partitions before.You could have a partition that was exactly the same as when you bought the machine. If that's what someone wants the gray disks will work. But you could also use the full retail version of any disc that will boot that machine.

I am lost now:
when you want more partitions and one of them is SL: ok go ahead with the retail disc.
when you only want 1 partition with one OS: use the grey disc.
I thought it was clear enough....

Ok. Now I get the confusion. The thread, as I understand it, is about creating a second partition. Even with one partition though the SL retail disc should boot any machine that can run SL. So here as I understand them are the options:

1. If you want to return the machine to SL and have other software that originally came with the machine use the gray discs. They must be discs for the same model Mac. This essentially gets the machine back to factory defaults.
2. If the Mac supports SL and you don't care about the additional software use the SL retail discs.
3. If the drive or partition contains something newer than SL the installer won't let you complete the install unless you erase the drive/partition in question first.

I'm sure someone in the brain trust will correct mi if I am wrong.
