Can't dual boot Leopard on MB Pro Mountain Lion

I'm wondering if it is possible to dual boot an earlier OSX version on a machine pre-installed with Mountain Lion.
I bought a new MBPro (9.2) which came with Mountain Lion pre-installed.
I also have the hard disk from my older MacBook (keyboard non-functional) which has two partitions: OSX Leopard (10.5.8 I believe) and Windows XP. I have put this disk in an external USB housing.
I would like to be able to dual boot Leopard on my MBP from the USB external HD and run Parallels/Windows XP and other OSX applications non-supported by ML also on that disk.
After plugging in the USB drive, I pressed the option key during boot and 4 are displayed; MacHD (ML internal), Recovery, MacHD (Leopard) and Windows XP.
When I select the Mac HD with Leopard to boot, the system crashes.
In case it helps, both the internal disk on the MBP and the external Leopard partition are formatted in Max OS Extended (journaled) and I can read/write all OSX files and run ML supported apps on the external HD when its plugged into the MBP running Mountain Lion.
Can anybody help on this?

No, it's not possible:

Dual Booting Leopard on MacBook Pro (Early '13)

Hello,
I'm desperately trying to dual boot Leopard (OSX 10.5) on my early 2013 MacBook Pro but am seeing no luck. I know the newer MacBook Pro models do not have the right drivers to run older software so I need a VM such as Parallels to run it. I got the trial version of Parallels but it keeps saying I need OSX Server Leopard. Is there any other way to dual boot leopard on my mac?
I'm wanting to do this as there are certain apps which require Rosetta to run, which support for on Mac was discontinued from OSX Lion.
Thanks in advance
Leon

You need:
1) Parallels (I know this one, I don't know others)
2) A DVD of snow leopard server from Apple ($20)
Then you can do this

Dual boot: OS X Mavericks and Mountain Lion?

Hi there,
searching the internet I found a lot of video tutorials and discussions about the proper way to partition your hard drive so you can boot OS X Mavericks from your Mountain Lion system.
However, having installed Mavericks right after its release, I'm trying to install Mountain Lion as a partition on my computer. That's because I need to run some apps which aren't compatible with Mavericks.
As the Mountain Lion installer consistently tells me that it wasn't possible to run the system on my computer I wonder whether there's a way to boot both, Mavericks and Mountain Lion once you have installed Mavericks.
I'm grateful for any advice.
Thanks,
Lukas

If you are trying to run the Mountain Lion installer from Mavericks, it will probably tell you it can't. I'm currently booted from Mountain Lion and tested the Lion installer and it told me no.
What you can do is make a Mountain Lion USB installer and boot from it. Now you can select the partition you created and install mountain Lion onto it. When the installer is finished (it will boot once at least), you'll be in Mountain Lion. To change back to Mavericks, open system preferences and select startup drive, there you can chose what starts at the next boot.
Instructions for making a Mountain Lion USB are here

My sister can't find Pages on her Macbook Pro Mountain Lion, can someone help?

My sister is new to her MacBook Pro Mountain Lion and thinks she may have deleted the Pages program. She's away at college for the first time and needs this program. I've told her to use Finder and search for Pages, or look in her applications, but to no avail. Help?

How did she acquire Pages in the first place?
If it was a purchase from the Mac App Store, all she need to do is launch App Store (from the  menu is easiest), sign in with the Apple ID & password used, click on 'purchases' & click the INSTALL button to the right of Pages in the list.
If it was from a retail DVD she will need the DVD to reinstall.

Isolated dual boot with OS mavericks and mountain lion

I just created a dual boot between mavericks and mountain lion (1 physical drive with two partitions) but I'm having troubles where they each see each other. Bin/ lib/ etc are fine (i think) as they are added via environment vars but it seems as though the spotlight privacy directories are shared. For instance, I thought I could simply add the other partition to the Spotlight Privacy list, ie while using mountain lion add /Volumes/Mavericks to the privacy list. However, when I added the volume in one, it also appears in the other. Another issue I've encountered is that while compiling on ML, I was getting errors complaining about the 10.9 sdk.
So, can anyone advise on the proper way to isolate these two operating systems with a dual boot scenario?
Thanks
Adam

Create two partitions on the hard drive. Install each OS on its own partition. This will only work if the computer can be booted from either version.

I currently run Mac Pro with three hard drives. Can I dual boot or even triple boot with Snow Leaopard on one drive and Mountain Lion or Lion on others?

I currently run Mac Pro with three hard drives. Can I dual boot or even triple boot with Snow Leopard on one drive and Mountain Lion or Lion on others?
I need to keep Snow Leopard so that I can run some old softward.

If you are careful you can put at least two on one drive, having Recovery from Lion and Mountain Lion on their own drives though.
CCC can clone Lion Recovery - great for moving or backup.

Can I dual boot snow leopard and mountain lion if I've installed boot camp on my drive

Can I dual boot snow leopard and mountain lion if I've installed boot camp on my drive

Yes as I said before. If your model Mac came with Snow Leopard and you are now running Mt Lion and have Windows installed in a Boot Camp Partition all you have to do is make the Mt Lion partition smaller, take the free space and make it another Mac partition and you should be able to install Snow Leopard into that partition.
I have Snow Leopard, Lion and Mt Lion installed on my MBP. No Windows in a Boot Camp partition because I run Windows XP in a Virtual Machine on both Lion and Mt Lion.

How do I partition my MacBook Pro so I can keep Snow Leopard and also install Mountain Lion?

How do I partition my MacBook Pro so I can keep Snow Leopard and also install Mountain Lion?
I want to install the latest OS, but I already know that I will lose a lot of my software unless I can partition the hard drive and have two "bootable" drives.
How do I retain everything I have, partition the drive, then reloa the software I own according to which OS it will work under?

I do not currently own OS X ML.
I am currently running OS X (10.6.8 Snow Leopard) on my MacBook Pro. It has a 2.8GHz Intel Core 2 Duo Processor. I want to upgrade to Mountain Lion, but many of my software titles will not operate with ML and I cannot afford to replace some of them (Adobe Creative Suite, for e.g.)
After I back-up my HD and then partition the HD, how do I use the back-up to reinstall what I want to the SL partition, and then place the rest on the ML partition.
I have not done what you want to do, so can only offer some general thoughts in support. Take value from the following where you can. No guarantees.
If it was me, I would use a disk clone utility (e.g. Carbon Copy Cloner) to image the existing Snow Leopard disk to an external drive. Then verify that the external drive would boot and run Snow Leopard normally.
I would then purchase and download the Mountain Lion upgrade installer, but not run it. Use Lion Diskmaker to make a bootable USB stick, and perform a clean install of Mountain Lion, replacing the Snow Leopard on your MBP. This way, you make absolutely certain that no third-party drivers or other SL cruft remains to make Mountain Lion unstable. Update to latest ML point release. Fix permissions. Let TimeMachine make a full backup of your ML installation to a different external drive. Then turn of Time Machine.
In Disk Utility, use the + sign at the bottom of the ML partition to add another GUID, HFS+ Journaled partition for Snow Leopard. Resize to taste. Name it differently from your ML partition. Exhale.
Now ideally, you would like to reverse the external clone and put it back into the new SL partition. Then fix permissions. And demonstrate that you can boot into individually stable OS X installations. This would save you alot of work. Resist copying your home directory into ML just yet.
If you cannot successfully achieve the preceding paragraph, you will be faced with a full SL and application reinstall.
The ~/Library contents for SL and ML are sufficiently different that you do not want to mix them. You may want to salvage Safari bookmarks.plist. And, ML created folders in the home directory may have different permissions or ACL settings than in SL. So, my rule of thumb would be to copy folders that you created in SL, and only the contents of matching named OS created folders such as Music, Pictures, Downloads, etc.
For each operating system, you probably want the Time Machine settings to exclude the opposite OS X partition. If you use the same host name in Sharing prefs, then you will mix SL and ML backups on the same Time Machine back up drive. If you use different host names, they will be distinct folders in the Time Machine backups.backupdb and allow discrete restores per host. You may also want to gag Spotlight from indexing the opposite OS X partition.

Can I dual boot OS 9 and 10.5 on one of these (G4 MDD)?

Simple question, can you dual boot OS 9 along side OS X Leopard on I'm looking a 1.25ghz G4 (single processor), basically the last one Apple ever released in 2003. It says in the specs for it that it can boot OS 9.2.2 and it is also compatible with Leopard. I know Leopard isn't compatible with the classic environment but I don't want classic in OS X, I merely want to be able to boot into OS 9 for some games, and when I want to use the web to be able to boot into Leopard.

Welcome!
Does anyone know of a good and trusted source for the original install discs for this machine?
Several people here have called Apple fpr these and were told they no longer carry replacement disks for this machine. It's back to eBay or the local Mac user group. Any used Mac that does not come with the system restore disks should be considered defective and avoided, or at least heavily discounted. Can the seller find the disks for you?
Every time I try to transfer a System Folder to the machine..........
That because you need the special version of OS9 on the system disk.
I do have a 733 G4 with a valid OS 9 System Folder. Can I transfer that via target mode and expect it to boot the 1.25?
I've not tried it but, based on my experiences with my MDD and its special needs, I don't think that will work.
If you get a righteous system restore disk set, there is one more hoop: OS9 will not boot if installed on a volume larger than about 195G. I tried installing it on a 250GB drive. It installed and would work in Classic emulation, but would not boot until I wiped that drive and made a modest partition in which OS9 resides.

As an aside, never be afraid to start a new topic in these forums. That usually will get you better help faster because some people will not read an addition to a thread that is already months old, like this one. I realize some web forums flame on people who start new threads but that is not the case around here. Tagging on to an existing thread confuses those offering help and dilutes the help that you and the original poster (OP) both deserve.
I realize that finding how to start a new thread around here is non-intuitive. This link should hep if you encounter what thousands of others have:

Can I dual boot with MAC OS/X and Windows

What is the best way to configure a dual boot on my MAC Bookpro laptop? Also, can I dual boot Windows 8 and MAC OS?

The first alternative is a dual-boot arrangement between OS X and Windows provided with OS X.
Windows on Intel Macs
There are presently several alternatives for running Windows on Intel Macs.
   1. Install the Apple Boot Camp software. Purchase Windows
         XP w/Service Pak2, Vista, or Windows 7. For Boot Camp
         4.0 and above you can only use Windows 7 or later. Follow
         instructions in the Boot Camp documentation on
         installation of Boot Camp, creating Driver CD, and
         installing Windows. Boot Camp enables you to boot the
         computer into OS X or Windows.
     2. Parallels Desktop for Mac and Windows XP, Vista Business,
         Vista Ultimate, or Windows 7. Parallels is software
         virtualization that enables running Windows concurrently
         with OS X.
     3. VM Fusion and Windows XP, Vista Business, Vista Ultimate,
         or Windows 7. VM Fusion is software virtualization that
         enables running Windows concurrently with OS X.
     4. CrossOver which enables running many Windows
         applications without having to install Windows. The
         Windows applications can run concurrently with OS X.
     5. VirtualBox is an Open Source freeware virtual machine such
         as VM Fusion and Parallels that was developed by Solaris.
         It is not as fully developed for the Mac as Parallels and VM
         Fusion.
Note that VirtualBox, Parallels, and VM Fusion can also run other operating systems such as Linux, Unix, OS/2, Solaris, etc. There are performance differences between dual-boot systems and virtualization. The latter tend to be a little slower (not much) and do not provide the video performance of the dual-boot system. See MacTech Labs- Virtualization Benchmarks, January 2013 | MacTech for comparisons of Boot Camp, Parallels, and VM Fusion. Boot Camp is only available with Leopard or Snow Leopard. Except for Crossover and a couple of similar alternatives like DarWine you must have a valid installer disc for Windows.
You must also have an internal optical drive for installing Windows. Windows cannot be installed from an external optical drive.

Can you dual boot lion with an older verion of Mac OS?

Can you dual boot Lion Os with and Older version of Mac Os (Snow Leopard?) So one can rum Power PC apps until they are upgraded?

You can dual boot if your machine originally came with an older OS version. No Mac can boot from an older version than the one it came with - notable exceptions are if the machine was built right around the time of the new OS release; in that case, it would depend on the machine and OS builds - it may or may not be possible.
So the important question here is: did yours come with Lion preinstalled? The answer is most likely: No. Or Snow Leopard? The answer would be: Yes.

I have the same trouble, I try installing rEFI but when I try start my Pro from DVD doesn't recognize.
Can I start from USB Memory? with files from SL DVD? or have some thing else?
I have original DVD of SL 10.6.3, if I buy the latest stable version, can I install? or the EFI firmware with Lion change again?
I try to use Lion, more than one week but I can't, and some app that I use for my profession, doesn't work, I really need downgrade to SL.

Can I dual boot Mountain Lion and OSX10.6.8

Can I dual boot Mountain Lion and OSX 10.6.8. I just upgraded to Mountain Lion and my InDesign CS2 no longer works. If yes, how does one do it.
Thanks all,

Yes, as long as your computer shipped with 10.6.8 or earlier. Insert the Mac OS X 10.6 DVD, restart with the C key held down, and install it onto a separate partition or drive; if you use Boot Camp, repartitioning the internal drive may disable it.

Can i run snow leopard on macbook pro puchased new in 2009?

Can I run snow leopard on macbook pro purchased new in 2009?

The Snow Leopard 10.6 DVD should still be available at this time 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. The App Store which is required to download 10.7 Lion or 10.8 Mountain Lion is part of the 10.6.6 update.
If you wait to long and 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 over $100 on Amazon.
