Install Leopard and Snow Leopard from an external drive?

Hey guys,
I have a 120GB ext drive and was curious as to if its possible to install Leopard and Snow Leopard from it if I have the DMG's. I guess my main question is how would I setup formatting in Disk Utility?
Thanks!

Set up two 10GB partitions and a third partition for the rest of the drive on the external drive, use Disk Utility to "Restore" the mounted installer DVD to a 10GB partition on the drive.
Plug the drive into a Mac and hold the option key down during boot. Select the installer you wish to use.

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

How to install Leopard from an external DVD reader?

Hi,
I've bought Leopard today. unfortunately, it's not yet installed on my PowerBook. As my SuperDrive is dead, I use now an external DVD (Lacie Portable DVD-RW), but it doesn't work. I can read the Leopard install DVD, but when it reboot, it reboot on my current installation.
I've tried the following during the boot sequence:
- alt pressed, but I can only see my main HDD
- c pressed, but I boot on my current installation
Can you tell me if it is possible to install Leopard from an external DVD, and how can I do that ?
Thanks in advance.
Regards,
Emmanuel Di Pretoro

Can you tell me if the same problem occur with a FireWire external DVD ?
It does not occur on your model of Mac.

Can I install Leopard on an external drive to run my computer?

Since it seems my hard drive has totally bit the dust, can I install Leopard on the external drive I use for Time Machine, and run my desktop from that drive? Could I run it from an external drive totally dedicated to Leopard? I am buying a new desktop soon, but I need info off of this machine. Can I plug in my Time Machine drive to my laptop and be able to use it without losing data?

Elizabeth Salcido wrote:
Thanks so much.
Youa re welcome!
I figured I would have to use a second drive. At least when I get my new desktop I will have a drive for Time Machine for both desktop and laptop.
If you really plan to keep the laptop around after you get your desktop, I would recommend replacing its internal hard drive. While running your laptop off an external is possible, it should be considered a stopgap measure. i wouldn't do it on a permanent basis. For one, as you'll find out, it's quite a bit slower than when using the internal drive.

HT2518 how do i or can i drag and drop files from one external drive to another ???HOW

how do i drag and drop files from one external drive to another, i cannt get both drives to open up. only one at a time.. i have alot to learn i know but that is where i am at the time...

You posted here so would assume you are also talking about running Windows.
Are the drives NTFS and use on Windows?
Are they Mac HFS formatted?
You likely will need NTFS for OS X in one case. to mount PC and use under Mac OS Lion
MacDrive to mount and WRITE to HFS drives under Windows

Can you install leopard from an external usb disc drive?

I don't know if the disc drive is fast enough for leopard or something. It's taking forever to open the installer, and when I restarted into the installer it just booted back to my desktop. I have an external disc drive I want to try. Can you install leopard from and external disc drive?

****, I just tried it and when I restarted it didn't go into the installer. I think my disc drive in my old mac mini might be too slow. It takes forever to recognize the disc and just to double click on it and it up. And when I tried to install it the first time from the internal drive it just booted right into my desktop again.

How do I install leopard on an external drive

I have been unable to install snow leopard on my external drive, when I put the install disc in the drive on the iMAC, it shows up on the desktop, but i cannot get it to install on the external drive, the iMAC has Lion installed.

I'd like an answer to the original question, too. I have a brand new Intel iMac which came preloaded with Lion. I'd like to install Snow Leopard on an external hard drive for a variety of reasons. I would rather NOT erase the internal hard drive of the iMac, if possible. Of course, I get this same message that, "You cannot install Snow Leopard on this machine running Lion" more or less. Does anyone have a method of faking out the installer so it will install Snow Leopard onto an external hard drive even though the Mac is running Lion?

Installing Leopard from USB flash drive

Basically i need to install Leopard from a USB flash drive on my Macbook, but i will sum up my issue: (I'm afraid i'm not a computer-"geek", so bear with me when i try to explain the issue :-))
My macbook hdd recently died on me, so put in a new, clean hdd. I now need to install Leopard on the new hdd from a DMG-file.
So, i have an 8GB USB flash drive and DMG-file of Leopard.
I formatted the USB flash drive to NTFS, and copied the 6+GB DMG-file onto the flash drive.
I tried booting from the flash drive by holding down the option key, but a blank screen shows up with a mouse pointer. There is no Flash drive or install icon to select.
Can anyone tell me, what i'm doing wrong?

Hi Dweepe;
On top of everything else the other posters pointed out, I would suggest that formatting the USB flash drive to NTFS is not doing you any favors either. NTFS is a propriety file system from Microsoft which the Mac can only read with special software install.
My suggestion is to replace your optical drive. A new one can probably be purchased for much less then the problems you are creating for yourself in your attempts to work around replacing it.

Can I install Leopard from an external USB DVD drive?

I am trying to install Leopard onto an older PB G4 whose internal drive is shot. I have an external Pioneer USB 2 drive attached, but when the Leopard Installer prompts me to restart, the installer doesn't kick in and the computer restarts into basic OSX. I've tried to choose the Installer DVD via System Preferences "Start-up Disk" pane, but it doesn't show up. The DVD drive does have its own AC power source.
Any help would be much appreciated! Thanks!

Mac OS X will only boot PowerPCs with Firewire, not with USB. That's the reason it doesn't work.

Installing Leopard From An External Hard Drive

Hi everyone,
It's been a long journey trying to get my mac fixed after it started acting up and obviously since I am posting here it is not fixed yet. I need to re-install os x on an external drive and it is telling me that I have to erase everything on the disk before I can install it, but I need everything on the external hard drive and paid the stupid geek squad 100+ $ just to put my stuff on it. I guess my question is: Is there any way to not have to erase everything on my external hard drive to install os x properly again?
I have an iomega external drive if that makes a difference.

Having all your data backed up is the best thing you could have done before doing anything else (but you probably knew that).
Reinstalling form an external drive is sort of right - you may want to look here
http://www.thexlab.com/faqs/kernelpanics.html
But if you're short on time you can insert the CD/DVD that came with your Mac and hold down the C key when you reboot. This will bot your Mac from that disk rather than your internal HD. Select the language once it boots, then choose DiskUtility from the Utilities menu. Try selecting the repair disk option. If that works, you'll be good to go. If that fails, you can choose the erase and install option. Once that [roces is complete, you can copy your data back to the internal HD.
However, if your internal HD is bad, or there is some other hardware problem, you'll be back where you started, and a call to Apple, an Apple Store, or an Apple repair shop may be in order.

Install leopard on an external drive?

Hi I was wondering if I can do a clean install of leopard on a usb external drive.
I originally did an upgrade install on my imac, but would like to play around with a clean install on an external. And if the setup seems faster would like to migrate it back to my internal. Just wondering if this would be possible? Thanks

Yes you can I have a clone of my internal drive with leopard using carbon copy cloner and it is bootable

I want to install OS X 10.3 from an external drive

my iBook is a dual usb

tom:
This is a bit involved, so let me see if I have it right.
You have Panther installed on an external FW HDD from your girlfriend's iBook.
You want to install (copy/clone) Panther from the external FW HDD to your iBook, and are having problems.
Are there original Panther install disks somewhere? On which computer is it installed?
Unless you have a multi-user pack the software was installed under a single user license agreement which says, in part:This License allows you to install and use one copy of the Apple Software on a single computer at a time. This License does not allow the Apple Software to exist on more than one computer at a time...In other words, as long as the OS is running on one computer, it is illegal to install it on another.
Good luck.

Downloaded new version of itunes, did a sync on my ipod and now music from my external drive is missing? Help

Downloaded new version of itunes, and then subsequently performed a sync on my ipod nano as I had purchased a new song from itunes store. I now only have 25 songs on my ipod as it removed all of my other music. My music is stored on an external drive. I downloaded the music there from cd's that I own. Can anyone help me fix this. I am going on holidays soon and want to have my ipod loaded with music for the trip. Thanks

hi mike,
First of all, your music is not gone. Its there, I promise. Second of all, you need to always make sure you backup your music elsewhere because funky things happen and computers do take nosedives.
Ok, go into File on the iTunes Task bar and click on add folder to library. Your music files should be under my documents>my music. Let me know how it goes...

Will LaCie D2 QUADRA with firewire restore my apps back onto my MacBook Pro if I upgrade to Lion and then restore from the external drive?

I ordered the disk to update to Snow Leopard. Did that so I could get the App Store. Did that so I could download Lion. After I installed Lion my MacBook is super sluggish. Takes like 6 seconds just to open a drop-down menu in Finder.
I have been backing up. Will LaCie D2 QUADRA with firewire restore my apps back onto my MacBook Pro if wipe my drive using the USB Lion OS stick (which I think I'll have to buy even though I downloaded the new OS online)? I have been plugging my laptop into the Lacie drive set on "auto" and it's been working great.
One Genius said yes "you will get everything back" but my Mac buddy says "say goodbye to most of your apps". Then a guy at the university I asked "do you have a disk image". And I said "what the **** is a disk image?".
Is the problem that I installed an OS on top of new OS without wiping the drive? Or, is my MacBook Pro too old? Do I need to buy a new one?
15-inch, Late 2008
Processor 2.4 GHz Intel Core 2 Duo
Memory 2 GB 1067 MHz DDR3

Any help?

SA will indeed transfer accounts, files and apps at first start. Can do so even faster if you clone the internal HDD onto the external (just split into a partition large enough to contain it) and then use it as the source. Probably faster than Time Machine too. The safest and quickest way to do a disk image or clone is using CarbonCopyCloner (free), and it will preserve the Lion Recovery Partition too.
Since you'll have to re--download the Lion installer again, note that you can concoct your very own Lion Installer USB Stick with it prior to reinstalling and not have to pay for the Apple-branded version. See Kappy's tutorial: https://discussions.apple.com/thread/3786371?tstart=0
As for the sluggishness, I believe that a great part of the cause is that you only have 2GB RAM. Don't know if your Mac can take more but try at least to get to 4GB, if not 8GB. Should attempt this before messing with the reinstall, as this may get you what you want.
