How to partition to install Snow Leopard and Lion on one computer
My first posting:
My iMac came with Leopard. I upgraded to Lion, 3 months ago. I found out that Appleworks doesn't work anymore... very displeased because I always used Mac Strong points (for the past 30 years), which is drawing, like McDraw, McDraw 11, Clarisworks, Appleworks, etc. Apple could have have included a software in iworks to open the numerous works I have done over the years in drawing. Now iDVD doesn't come with Lion anymore. Another blow from Apple!! And iDVD 7.1.2 (after upgrade from Leopard's iDVD) doesn't work too well in Lion... quite a few things are wrong.
Consequently, I want to install Leopard in an external HD, where I could use Appleworks and iDVD.
I have a 1 tera WD Firewire as an external HD. I have tried a few ways to install Leopard on my external HD with no succes.
I have tried "partionning" the external HD, but when it came to "Scan disc image" of Leopard, I had the message: Unable to scan "Install" (Resource busy)
I have tried to install with original Leopard DVD, but after pushing restart (to chose my external HD), then my computer keeps asking me to push restart.
Can anymore can tell me how to properly install Leopard on my external HD?
MartinR says:
Connect your WD Firewire drive. Open Disk Utility and check to make sure that it is partitioned as GUID partition scheme (assuming you have an Intel iMac) and is formatted as Mac OS Extended (Journaled). If not, you will need to repartition and reformat the drive - note that this will erase everything that is on the drive.
Notes:
-If you have an Intel Mac you cannot install OS X to a drive that is partitioned as Apple Partition Map; it must be GUID Partition Scheme.
-Mac OS Extended (Journaled) is the same as the "HFS+" as previously mentioned.
-For the disk to be bootable it must be formatted as Mac OS Extended (Journaled) not plain Mac OS Extended.
Next, insert your Leopard install DVD in your iMac. If the installer opens, just exit/close the installer window. Do not remove the Leopard install DVD from the drive.
Shut down your Mac. Then restart it by holding down the "C" key while it starts. This will make your iMac start from the Leopard install disk that is in the CD/DVD drive. You should then be able to select your external WD drive and install Leopard there.
My response to MartinR (I appreciate the dedication of the helpers)
I tried MartinR solution but it doesn't work. When I restart and keep "C" depressed, after a while, a kind of gray drape closes the screen and tells me I have to restart my computer par pressing "restart" for a few seconds. Then when the computer reboots, it tells me there was a problem and had to restart the computer with a report to Apple window.
I wonder if my computer is not defective? In 30 years, this is the only Apple computer that broke down on me (Always been faitful to Apple computers in spite of the fact they had little apps then), and twice on top of that. The first repair was done by Apple in Wellington Mall, Florida (hard drive had to be replaced); the second time was Northstar Computer in Sudbury, Ontario (optical drive had to replaced). Maybe that tells us something? Were replacement parts up to par? My computer seems to be working OK. I verified my HD with Disk Utility, and everything was OK.
My computer is an Intel Core 2 Duo, 3.06 GHz and 4 GB of ram.
My WD external drive is formatted as GUID Partition Table, and Mac OS Extended (Journaled).

Can't recall which I used to do the dynamic repartitioning.
I'm betting that it was originally Partitioned with Snow Leopard.
As a test I just added a second Partition with Mountain Lion to a FireWire HD and it would not let me Install Snow Leopard from my System or Retail Disc into the Partition.

I accidently installed lion on my mac book pro. I did a time machine back-up. When i try to re-install snow leopard, it won't take. Any suggestions on how to install snow leopard over lion?
Accidentally, eh? How, might I ask?
Downgrade Lion to Snow Leopard
1. Boot from your Snow Leopard Installer Disc. After the installer loads select your language and click on the Continue button. When the menu bar appears select Disk Utility from the Utilities menu.
2. After DU loads select your hard drive (this is the entry with the mfgr.'s ID and size) from the left side list. Note the SMART status of the drive in DU's status area. If it does not say "Verified" then the drive is failing or has failed and will need replacing. SMART info will not be reported on external drives. Otherwise, click on the Partition tab in the DU main window.
3. Under the Volume Scheme heading set the number of partitions from the drop down menu to one. Set the format type to Mac OS Extended (Journaled.) Click on the Options button, set the partition scheme to GUID then click on the OK button. Click on the Partition button and wait until the process has completed.
4. Quit DU and return to the installer. Install Snow Leopard.
This will erase the whole drive so be sure to backup your files if you don't have a backup already. If you have performed a TM backup using Lion be aware that you cannot restore from that backup in Snow Leopard (see below.) I suggest you make a separate backup using Carbon Copy Cloner 3.4.1.
If you have Snow Leopard Time Machine backups, do a full system restore per #14 in Time Machine - Frequently Asked Questions. If you have subsequent backups from Lion, you can restore newer items selectively, via the "Star Wars" display, per #15 there, but be careful; some Snow Leopard apps may not work with the Lion files. -
Since installing Snow Leopard and then Lion on my Intel-based iMac two weeks ago, my iTunes program seems to open at will whenever the computer is on. It often begins playing music, as well. What is causing this and how do I make it stop?
There are ways to minimize, mitigate, and help avoid a lot of problems.
Bootable backups.
Zeroing a drive twice before using, and format it with SL DVD Apple Disk Utility for sure.
Even a clean install should import old apps without having to reauthorize.
If you must do an upgrade, do it from the SL DVD, after repairing the drive and be sure to use the SL version of Alsoft Disk Warrior (4.2).
Wait six months before jumping on a new OS.
10% is still too many. Yes, it is more sensitive to RAM and hard drive errors, doesn't like some controllers; most ext hdd cases; and enough software to make for test-only status. And it only IDs some known incompatible applications, drivers, extensions, etc and does not remove even those always in best manner.
Plus, there are problems with the new Rosetta and the cache files it now uses. So some apps and plug-ins will cause more trouble. Not all are ready. Good reason to hold off for the months it takes.
Other devices act different as far as on/off behavior.
(Migrating from G5s to Mac Pro can cause all kinds of problems, weird behavior, sluggish system, and why anyone that went down that road was strongly recommended to NOT use Migration Assistant for any of their applications, and to ONLY do clean/fresh installs of any apps. If you skipped that day, didn't read the Guide to M.A., or didn't want to do fresh installs then, your system could have been on borrowed time. If you did do clean install of applications, great.
Installing SL can result in a corrupt directory - I think and it "seems" to be happening, but no real proof, just gut feeling and instinct (underlying file system problem? weak sectors that pre-existed waiting to happen?).
Remember all the "there just aren't a lot of 64-bit drivers" for Vista and XP? it's come home to roost.
... my guess is not enough incense and offerings. To hop into TimeMachine and SuperDuper backup images and pull the 1TB for another day (week, month, year). -
I need to run I need to run snow leopard and lion on same computer?er
I have a Mac Pro and a extra internal hard drive that I would like to put lion on the extra one and run snow leopard on my original one and be able to boot from either one. How does one go about doing this or is it possible?
OPTION key will continue to work. Can alspo be used to select an external clone (CarbonCopyClone, $40 download) backup to boot in case of HD failure. AND OPION key can be used to select the "Recovery Partition" of Lion in case you need it (Command-R also accesses the RecoveryPartition).
A welath of OPTIONs ... really. -

Currently, I have Leopard 10.5.8. How can i download and install Snow Leopard or Lion? Thanks for your help.
You need to *call* Apple at 1-800-MY-APPLE, as Ralph already said.
But "since one week" sounds like a direct translation of French "il y a". You should call your local country's Apple suuport and ask.

How do I make a back up system disk. I wish to run snow leopard and Lion on 1 drive.
I wish to run Snow Leopard and Lion on 1 Hard Drive. I need to back up snow leopard and then install Lion. Any suggestions on how to do this?
Too follow up on this topic - I have recently upgraded to 10.8.2. I have a complete backup HD with SL inclluding some SL-only programs on it. What I want is to make a small size, just SL and my few programs, hard drive with which I can boot when needed. Is it possible to trash all the many programs I have on the SL drive and just keep certain ones? How?
Thanks you for any advice,

Had to get new hard disk for my macbook. After installing snow leopard on new HD the computer only connects to free wifi at certain places and not others. Took it to genius bar (of course it worked find there!) they said it was fine. But problem persist.
Hi there ricalimo,
I would recommend taking a look at the troubleshooting steps in the article below. If the issue is location specific, than you may want to save the article so you can perform troubleshooting when you are experiencing trouble.

How can I re-install Snow leopard having installed Lion? The disk supplied states that I cannot use the version of 'Install Mac OS X'...HELP!
None of the instructions usually given for downgrading seems to mention the fact that you will lose some data in built-in applications, including at least Mail. When you installed Lion, your Mail database was converted from the format used by Snow Leopard's Mail to that used by Lion's Mail. There is no way to reverse that conversion. Therefore, you will lose your entire Mail database. If your messages are all stored on a remote server, that may not be an insurmountable problem, but otherwise you'll have to restore from the last backup you made before the upgrade, and then you'll still lose all changes to the database made since that time.
Another fact not often mentioned is that downgrading is usually the worst possible solution to a problem with Lion. But that's the answer to a question you didn't ask. -

You may be in the same boat as me.
I deliberately bought a refurb Feb 2011 MacBook Pro, because it would have originally shipped with Snow Leopard. I have to run an application for my job, which does not run under Lion.
Unfortunately, Apple is now upgrading all Snow Leopard machines, before selling them as refurbs. I purchased a legal copy of Snow Leopard, and have tried various downgrade solutions that I found posted on the net, without success. No matter what I do, it always goes into "three beep mode" after trying to install Snow Leopard.
The latest development came this evening, while I was talking to the "geniuses" at Apple. Apparently, there is now a firmware revision that loads the first time you run Software Update under Lion, and it locks the machine so that it can't revert to Snow Leopard.
The only option they have been able to offer me so far, is to return the machine and get a refund. This is maddening, as I HAVE to have a Snow Leopard machine, and can't find any other way to purchase one. -
I've installed snow leopard and now my MX860 won't scan
I've recently installed snow leopard and now my Canon MX860 won't scan. I've reinstalled the scan driver from the Canon website. Any other ideas?
I suggest that you open Print & Fax, select the MX860 under the scanner heading and remove it using the minus button. Then, still in Print & Fax, click the plus button to add the scanner again. The Add Printer browser will appear and with the Default icon selected the MX860 should appear as a printer and a scanner. Select the scanner entry and ensure the Print Using menu changes to Canon MX860 series. Click Add to complete the creation of the new scanner queue. Now test the new scanner by selecting it in the Print & Fax > Scanners list and then pressing Open Scanner.
