Install Leopard beside Snow Leopard

In my company we need to do testing against Snow Leopard and variations as well as retro testing with Leopard, Panther, etc...
My 21" iMacs 500GB HDD has been partitioned into different drives. Snow Leopard on Fixed (aka don't erase). And different variations on the other drives.
However when I put my Leopard disk in to install, set it as the startup disk and reboot it reads and gives me a white screen...
I restored the .dmg to a USB drive, set that as the startup disk and reboot, white screen...
Restored to another partition, attempt to boot that partition, white screen...
This is happening with all my install disk (we have 3 in the shop) and Mac OSX Server 10.5, just to verify that we don't have bad media...
Is this a "feature"? If you buy a Mac with a new OS you can't install an older OS or am I missing out on something here?

If you buy a Mac with a new OS you can't install an older OS
Correct.

Install Disk for Snow Leopard will not boot on an iMac 27in

My Install Disk for Snow Leopard will not boot on my iMac 27in. The Apple Logo is the only thing the user will see. The current OS on the system is 10.6.6. Upon placing the Snow Leopard DVD in the system, the DVD players spins for a few seconds and displays the Apple Logo. Nothing happens after 20 minutes.

Yes, it is ridiculous how it is impossible to install Snow Leopard. I have two Snow Leopard DVDs: one that I purchased for a Macbook soon after it's release (10.6.0), and one that came with my iMac (10.6.4). Both of these boot up my Macbook (running 10.6.7) just fine. My SL 10.6.0 DVD mounts onto my iMac (Lion 10.7.0), but you cannot run the install. I attempted to boot from this DVD and got the infinite white screen and Apple logo, as some have reported above. The other SL 10.6.4 DVD will not even mount in Lion, and will not even show up as a bootable drive when I attempt to select it after holding alt/option on reboot.
I created a bootable external drive from SL 10.6.0, attempted boot, same infinite white screen/apple logo.
I created a bootable external drive from SL 10.6.4 on my macbook. I attempted to boot from this drive, and got the white screen of death, except that this time I actually got the loading symbol underneath the Apple logo. After about a minute of attempting to boot, the Apple logo changed to a circle with a diagonal line through it (the "NO!" sign).
I took my iMac to the genius bar. They inserted SL 10.6.0, which would not boot. Then they determined that my computer had to run 10.6.4 and later. So, they restored an image of SL 10.6.4 onto my partition (not an install from an image, but an image of SL already installed). Hurray! Snow Leopard was successfully shoved onto my iMac!
I then deleted a third partition on my hard drive I did not need anymore, which somehow screwed up my SL partition (even though it said "Will not erase partition SL or Macintosh HD). Now I am back at square one, and I guess I need to take my flippin iMac back to Apple for them to do what I should be able to do.
I like Apple, but sheesh do I hate Lion right now.

I upgraded to snow leopard but iphoto was not included. How do I install iphoto on snow leopard 10.6.8?

i upgraded to snow leopard but iphoto was not included. How do I install iphoto on snow leopard 10.6.8?

IPhoto is not included in any OS upgrade. It is a seperate application. Unless you choose to erase your drive when you upgrade no application including iPhoto is affected by the upgrade (except potential compatibility issues). If you need to reinstall iPhoto for and reason you do it from the original source. Either
1- the restore disks that came with your computer
Or
2- the iLife DVD upgrade that you purchased
Or
3- the App store

Mountain Lion won't install on 10.7.4. Suggestion from Apple is to completely erase harddisk and install Leopard Snow Leopard Mountain Lion. Is there no other way to install Mountain Lion

Mountain Lion won't install on 10.7.4. Suggestion from Apple is to completely erase the harddisk and install Leopard > Snow Leopard > Mountain Lion.
Is there no other way to install Mountain Lion?

I tried and failed for several hours to install Mountain Lion, and was repeatedly getting the "Recovery System" cannot be created error. I tried all the tricks: resizing the drive partition, booting from an external boot drive, all to no avail. After reading other users struggling with the same issue, I had determined it to be a boot camp drive error. However, I didn't want to have to erase and begin anew when I came upon a possible solution. I had long ago renamed my boot camp drive with a "." (".windows" for me) in order to avoid having the partition show up on my desktop. So, I boot into windows and renamed the c: drive without the "." ("windows"), and reboot into os x. The install then went off without a hitch. I hope this will be helpful for others struggling with this issue that may have renamed their boot camp drives in a similar manner.

Install Leopard with boot camp on snow leopard.

I upgraded to Snow Leopard and have a piece of line 6 hardware that is not compatible. Updated drivers are taking forever to come out and I need to use this hardware. I'm wondering if it would be possible to use boot camp to install leopard from the installation disk included with my macbook so that I can boot to it to use the line 6 device.
Any help would be appreciated.

The easiest way is to use Disk Utility in the Utilities folder to create a 2 partition set up. Disk Utility will be able to do this without erasing your existing information.
- Select your volume the one with the disk size at the top
- Click on Partition
- Change the Volume Scheme to 2 partitions
- Answer any messages and such
I am sorry since I have mine partitioned with BootCamp for my Windows 7 partition, I am unable to describe all of the steps as BootCamp locks me out of performing the rest of the steps.

Re-Installing Mac OS (Snow Leopard)

I've seen some other posts about upgrading the OS drive and cloning, however, I have not seen any posts for what I would like to do. My main concern is whether or not what I am planning to do is correct.
I plan on upgrading my Mac Pro with 4x1.5TB Seagate Barracuda 7200rpm drives. Replacing the 1x250GB (OS Drive) and 3x500GB data drives that I currently have. I plan on making all 4x1.5TB drives as a single large RAID5 disk, then create multiple partitions for the OS, Data, etc.
My first question is if this is a good idea to do? I'm looking at using RAID in the event of a disk failure since there will be a lot of data stored (approx 4.5TB).
My next question is how do I clone/restore my existing OS drive onto the new disks/partition? I don't want to go through the exercise (if I don't have too) of reinstalling all my software, license keys, etc. I do use time machine to maintain a backup of OS drive on an external 1TB disk. So I was planning on trying to leverage it to restore the OS disk onto the new partition.
So here is what I was planning on doing:
1) Backup the OS drive using time machine
2) Pull the old drives and replace them with the new
3) Install Snow Leopard, creating the RAID5 disk using the 4x1.5TB drives
4) Restore the OS disk completely from Time Machine Backup.
Will this work? And is this the correct way to do this? Or is there a simpler way?
Last question, does anyone know if I have to first install Leopard then upgrade to Snow Leopard since I only purchased the SL upgrade or can I do a complete new install using the SL disk?
Thanks in advance!!!
Bob

Not sure if you realize you need PCIe hardware RAID controller.

Forget TimeMachine for cloning your system, Apple DU Restore or SuperDuper does fine (you can still use T/M if you want).
There is no software way to create RAID5.

Re-installing Leopard after installing Snow Leopard?

I recently installed Snow Leopard, but want to re-install Leopard instead without losing all of my current data (Applications, folders...aka everything) - is this possible?

First, note that above I said: "final step is to do an erase and install of Sno." Where I said Sno, I meant Leo.
You can do your reinstall of Leo more simply than I mentioned before. What I was am trying to do is to give you the best chance of moving back to Leo successfully without having to reinstall your apps. What I was going to tell you about is complex.
To avoid the complexity, here is what I recommend. Make the Sno clone I mentioned before for safety and to have easy access to your data for future drag and drop. Now, just do an erase and install of Leo on your internal drive; reinstall your apps by hand; and drag and drop you data into the appropriate folders on your new install.
If you don't want to reinstall your apps by hand, then I'd recommend that you go the more complex route I started describing. I am hoping that you don't have so many apps that you won't choose the more complex procedure. I apologize for the confusion I probably have created. Just let me know which way you would prefer to proceed.

Install Leopard on an External Drive on a Snow Leopard Mac Book Pro

Hi
I have a MBP 17/CTO 2.66GHz i7, which came installed with Snow Leopard.
I've used boot camp to install Windows 7.
I've attempted to install Leopard 10.5.4 on an external drive.
The steps I've taken:
1 - Connected my WD Passport on the Firewire Port
2 - Partitioned the drive. The first partition is 100GB, Mac OS/X Extended (journal) and I've selected the GUID Partition Scheme
3 - Inserted the Mac OS/X Leopard DVD, and followed the instructions to restart
4 - On restart I have three options. Mac OS, Windows and Install Mac OS\X
5 - I select Install Mac OS\X.
6 - The disc spins for a few moments and then the laptop freezes
Beware of the following issue:
1 - On restart more often than not, the DISC will spin and then the laptop will freeze.
2 - To overcome this, restarting pressing the ALT (option) Key.
3 - You should see your boot options. If you do not see "Install Mac OS\X", then eject and reinsert the disc.
The question maybe why would I want to have an Leopard Installation when I have Snow Leopard. The software I develop has thrown up a number of differences between Leopard and Snow Leopard, hence I need both OS's to support my software.
I mentioned this to the Apple Store before I purchased my machine. They put me through to a senior technician at Apple Care, who told me it would be possible to have the set up I am after; and to contact Apple Care if I ran into any difficulties.
After I received my laptop and ran into the problems I described above I contacted Apple Care, only to be told by a senior technician that it should be possible to install Leopard on an external drive, but Apple Care cannot provide any support or assistance.
I really do like the laptop and would much rather not return the laptop; but I really do need the setup described.
Anyway I have tried a number of different approaches:
1 - Having no partitions (so just the single partition)
2 - Trying all three Partition Schemes:
- GUILD Partition Table
- Apple Partition Map
- Master Boot Record
All resulting in the same problem.
I can confirm the external drive does appear as bootable in disc info.
My guess is one of the following is preventing the install:
1 - It is simply not possible to install an earlier version of Mac OS\X than 10.6 on the laptop I have, even if I tried to install on an external drive. This restriction is built into some hardware confirguration. So even if I wiped the internal hard drive or added a new partition to the internal hard drive, I would not be able to install 10.5.4. I say this may be a reason as the second technician told me the CPU has built into it a process which prevents installing older versions of Mac OS/X, but that it should NOT restrict installation on an external harddrive.
2 - When trying to install Mac OS/X, a search is carried out for an external drive which has the correct format. For some reason it may be that this search is not finding my external drive?
I'm a little stuck here and quite disapointed that the support promised by Apple Care for assistance in setting this up, is now not forth coming.
Any help or suggestions would be appreciated, as ideally I would prefer to keep and not return the laptop, it's a beautiful piece of machinery.
Cheers
Parmy

The mystery continues...
I have an older MBP (2.33 GHz Intel Core Duo) which came installed with Tiger. I can confirm I purchased a genuine copy of Leopard (10.5.4) from the Apple Store and it’s not an OEM version. I installed 10.5.4 without a hitch on my old MBP internal drive. It is the only OS installed on my old MBP.
Using my older MBP (which through software updates is now running 10.5.7), I managed to install 10.5.4 onto my external HD (WD My Passport Studio – 640GB FireWire 800).
However; on the final restart, the screen remained grey and 10.5.4 did not boot from the external drive.
I restarted the machine holding down the ALT (option) key, and only two options appeared, Macintosh HD and the Install DVD. I selected the Macintosh HD and opened System Preferences.
In System Preferences --> Startup Disk, I discovered the partition on my external HD which contains 10.5.4. I selected this partition and selected restart.
On restart my MBP displayed a grey screen, and the blue light on my hard drive flashed slowly. I left this for an hour, however; the OS did not start and the screen remained grey.
I then plugged my external HD into my new MBP which I started holding down the ALT key.
To my surprise I found 3 boot options (Macintosh HD, Windows and Leopard). Leopard being the partition on my external drive, which now has 10.5.4 installed.
I selected Leopard, but sadly after 30 minutes, the OS failed to boot.
Although this deviates slightly from this post, I fail to understand the problem here:
1 – Why can’t I boot 10.5.4 on an external drive, from my old MBP? Surely this is not because my old MBP is now running 10.5.7?
2 – Why can I see 10.5.4 as a boot option on my new MBP but not on my old MBP when I start the MBP holding down the ALT key?
I doubt there is a problem with my external drive, as it seems to read, write, etc... in all normal cases.
Whilst it definitely appears that I won’t be able to boot 10.5.4 on an external drive from my new MBP, I should be able to at least boot it from my old MBP, which would give me the option of installing Snow Leopard and Windows on the internal drive of my old MBP.
Apologies for keeping this post going, but I hope by getting to the bottom of this, it will help other Mac users as well.
I’ve run out of ideas of things to try, so I will give Apple Care another call in the morning, and will report back.
Any suggestions of other things I can try?
Cheers

I have tiger (10.4.11), and I would like to upgrade to snow leopard(10.6). Do I need to install leopard(10.5) first?

Do i need to install leopard first? I was planning to but snow leopard off of amazon.

The Snow Leopard 10.6 DVD should still be available from Apple for $20. You will have to call Apple Customer Care 1-800-692-7753 or 1-800-676-2775 to purchase it. It may still be in the Legacy Products list.
If they no longer have any in stock you will have to buy it from eBay or Apple resellers that still have stock. But you will have to pay a premium since the DVDs are no longer being made. Snow Leopard DVDs are already up to $100 on Amazon.

Need help removing Snow Leopard and Installing Leopard

Snow Leopard was a waste of time and money. Time I could have used for much more productive work.
How can I remove snow leopard and reinstall leopard. I have the installation disc for Leopard. Can I simply install it over the top of snow leopard?
That would solve my problem for one machine (the iMac) but how do I go back to leopard if I don't have the disk? I suppose there is dmg somewhere but I haven't looked so I apologize in advance if the answer is obvious.

Insert leopard install disk-select install.
It will wipe the drive and install Leopard-all data will be gone.
You must have a legitimate, legal copy of leopard.
If you backed up the leopard dvd, you would have to burn it or figure a way to do a network install.

How can I format an HD with System 10.4 and install Leopard Snow?

How can I format an HD with System 10.4 and install Leopard Snow?

You need to partion the hard drive using Disk Utility. On one partition install 10.4. On the other 10.6. As a note I trust you are doing this on a MBP and not a PPC Mac because 10.6 won't install.

Just installed mac osx snow leopard upgrade and connected my printer to it too, and realized I have no sound anymore

Just installed mac osx snow leopard upgade and connected my printer too, and realized I have lost sound!   Can anyone help?

In case I misunderstood, did you mean that the 10.6.3 version of Snow Leopard was the upgrade? If so you need to update via 10.6.6 to 10.6.8. These updates can correct minor system upsets.
And ... did you also repair permissions both before and after you upgraded.   You should do this when you progress via 10.6.6 to 10.6.8 too.
