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?

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?

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.

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 do I install Leopard on an external?

I have a MacBook that for some reason won't take an OS. My thought is to install the OS from my MacPro on a 2.5" in an enclosure and put it in the MacBook.
How would I go about installing Leopard on my hard drive this way?
-Kyle

Installing onto an external HD should be a routine matter. Ensure that the ext HD is partitioned w/a single partition, has the GUID partitioning scheme, and is formatted Mac OS X. Personally, I prefer FireWire to USB. FW is significantly faster than USB. BTW, ensure that the MacPro has the latest OS update on it. That should allow it to boot the MacBook, but I don't have either to do any testing. BTW, if you're getting those machines sans their HDs because of problems, my experience indicates that most issues are SW related and not HW related.

How do i install itunes on an external drive

How can i install iTunes on an external hard drive?

Thanks, but I'm not referring to the music library, I'm referring to the actual iTunes application. I've read other threads saying that it can only be installed on the C: drive, so guess i'm out of luck.
Thanks anyway!

How do I install Leopard on my external FW drive?

Hi, 30 minutes ago I went out and bought a new external FW 750gb drive. I was planning on using the method described in here:http://www.macfixit.com/article.php?story=20071025100548752 but you now have to pay for it and I don't want to for one bit of info. How was it done. I want 4 partitions. I want the leopard boot disc on one partition, leopard on another. Time machine on another and a folder for my music backup lastly.
Any help anyone? I don't even know which type of data to have it formatted in. Journaled, extended etc.

The key to the install on an external firewire drive that you want to use with Leopard as a boot drive is this... go to the disk utility and click on the firewire drive in the left column. Go to the Partition tab, click it and under the "Volume Scheme:" click on the button and select the number of partitions you want to set up. Now go to "Options" at the bottom of the menu and click it to discover the trick to this settup: select the first partition scheme "GUID Partition Table" and then click "OK"
Don't forget to name each partition in the first menu and make sure the format is Mac OS Extended (journaled) if you desire the journaling feature. Now click on the "Apply" button and you will now be able to boot the Leopard install disk and select the external firewire drive for the install. I did this and it works great!

How do I install base system on external drive to boot MacBook Pro?

I have a MacBook Pro 2.2 core 2 duo. I use an external HD for storage. Want to make external drive bootable (i.e. to run apps like DiskWarrior on MacBookPro).
How do I install the base system?
Thank you.

First, be sure the external drive is partitioned using the GUID partition scheme. If it isn't then you will have to re-partition the drive which will erase anything you have on the drive.
Second, the external drive must be formatted Mac OS Extended (Journaled.)
Last, boot from the OS X Installer Disc One that came with the computer and install OS X onto the external drive. Do not do an Erase and Install if you don't want to erase the external drive. You can customize the installation to omit any additional components you don't need such as language localizations, Asian Fonts, unneeded printer drivers, etc.

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

How do I Install OSX to an External Drive Partition?

I have an external FW800 drive that I've made two partitions on. One partition I want to install OSX to, for external booting; the other partition is just for storage. I'm trying to use the SNL install disk but It's not installing, it just stalls out. I must be doing something wrong.
Thanks,
John

Is the external drive prepped correctly?
Drive Preparation
1. Open Disk Utility in your Utilities folder.
2. After DU loads select your hard drive (this is the entry with the mfgr.'s ID and size) from the left side list. 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. Select the volume you just created (this is the sub-entry under the drive entry) from the left side list. Click on the Erase tab in the DU main window.
5. Set the format type to Mac OS Extended (Journaled.) Click on the Options button, check the button for Zero Data and click on OK to return to the Erase window.
6. Click on the Erase button. The format process can take up to several hours depending upon the drive size.
Steps 4-6 are optional but should be used on a drive that has never been formatted before, if the format type is not Mac OS Extended, if the partition scheme has been changed, or if a different operating system (not OS X) has been installed on the drive.
When formatting has completed quit DU and return to the installer. Complete the OS X installation.
Or you can clone your current system to the partition:
Clone using Restore Option of Disk Utility
Open Disk Utility from the Utilities folder.
Select the destination volume from the left side list.
Click on the Restore tab in the DU main window.
Check the box labeled Erase destination.
Select the destination volume from the left side list and drag it to the Destination entry field.
Select the source volume from the left side list and drag it to the Source entry field.
Double-check you got it right, then click on the Restore button.
Destination means the external drive. Source means the internal startup drive.

Installing Leopard on an external HD

I have a MBP for work, which is still running Tiger. Nevertheless, I would like to play around with Leopard and was wondering if I can run it on an external (bootable) HD.
If so, I have a few questions:
- Do I need Firewire 800 or can I use USB 2.0 (the MBP is Intel, not PPC).
- How complicated is it to install Leopard on en external drive?
- How can I make an external drive bootable.
- How can I choose which drive to boot from?
Thanks a lot,
Stefan

The good news is that this is a pretty straightforward process (I have done this, and trust me, I'm no expert!) Intel Macs will happily boot from a USB 2.0 disk. First, if you haven't already done so, partition the external in disk utility. Make sure you choose 'Mac OS Extended (journaled)' as the format. Under 'volume scheme', choose how many partitions you want, and their size(s), then under 'options', make sure you choose 'GUID partition table'. Insert the leopard installation disk, choose the external as the destination volume, and install in the normal way. To choose which drive to boot from, hold down the option key at startup and you will be asked to select a drive.

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.

HT4904 Help. I have an older 20 inch iMac and had Lion running on it but the internal hard drive died. I'm trying to install Lion on an external drive but it doesn't look like Lion Recovery is supported. I have Leopard installed but am stuck.

Hello,
My 20inch iMac's internal drive died and I'm trying to re-install Lion on an external drive. If I could get the Lion DMG file I think I'd be all set but am not sure how to do this. It doesn't look like the Lion Recovery feature is supported in my older iMac. And I have Leopard installed on the external drive but there's no AppStore to download the Lion DMG file.
Any suggestions?
Thanks,
-Lee

Without a bootable backup/clone or a Time Machine backup of your previous Snow Leopard installation or a saved copy of Lion's install app, you'll have to upgrade your Leopard volume to Snow Leopard (10.6.6+) so you can waste another hour or more DLing the Lion thing again.

How do I install Leopard on the partition I've created on my MacBook Pro running Lion?

I've partitioned my hard drive (running Lion) so that I can run Leopard. How do I install Leopard on the partition? I've put in the Leopard CD and restarted, but all I get is a black screen with a bunch of gibberish.

There's no way the MacBookPro will boot to Leopard.
Snow Leopard may be possible, but you'd need the original discs from Apple customer Service - the retail disc isn't a high enough version.
To check viability of Snow Leopard, have a look at a.brody's article;
https://discussions.apple.com/docs/DOC-2455
If it looks like SL is feasible ring the Apple Customer Services with the model and serial no. and see if the original SL discs are available.

How can I install ntfs on an external hard drive so that my Samsung Smart TV can see my media files? Or is there a better option?

How can I install ntfs on an external hard drive so that my Samsung Smart TV can see my media files? Or is there a better option?

OS X cannot natively write to a drive formatted as NTFS, nor can it format a drive as NTFS. There are third-party NTFS drivers available on the market.
Just out of curiosity: Even with NTFS, how is your TV going to access the external hard drive? Does the TV have a USB port?

Installing Leopard on an external as a subordinate boot.

Aloha All
I just finished the transfer of all my back up data from my external onto my iMac and (very essential onto DVD) So I'm ready to reformat and install Leopard on the external as a secondary OS. I'm running Tiger on my native HD and my intention with running Leopard on my EHD is just to learn the changes.
External HD is F/W 7200 rpm, 250GB and my only intention is to look and learn the new OS before I move it onto my iMac. any advice, warnings.

Rick:
I did something similar. I first tried doing an Update install on a clone of my internal drive on external drive, but that resulted in 8 hours of frustration (described in my reply to Eric W. in Apple - Support - Discussions - Blue Screen on MacBook Resolved ...).
However, when I erased the external partition (not as drastic a step as reformatting it, as you intend to do) the "virgin" install went smoothly & I am now running Leopard from that partition with no problems noted so far.
My guess is you will have no problems if you do what you contemplate.
Good luck!
