"How to install Snow Leopard from an External Hard Drive"
* Launch Disk Utility
* Select the External Firewire/USB device that you want to use as the boot drive for the upgrade
* Click “Partition” from the menu options
* Select 1 Partition, then click “Options” below the partition scheme
* Select the top option for “GUID Partition Table” – it MUST be GUID to be bootable!
* Click OK to create the GUID partition (this will reformat the drive, ie: all data is lost)
* Next, click the “Restore” tab within Disk Utility
* Select your newly made Snow Leopard 10.6 Install DVD image and restore this image to the GUID partition you just created OR…
* Alternatively, you can select the Snow Leopard Install DVD and restore directly from the DVD to the GUID partition
* After the restoration is complete, your GUID partition will now be bootable by Mac OS X!
* Reboot the Mac holding down the “Option” key to pull up the boot loader, select the Snow Leopard install drive you just created rather than your default Mac OS hard drive
* Install Snow Leopard as usual!
Hope this helps!

After installing snow leopard my external hard drive won't show up on screen or backup

Afer installing leopard my external hard drive won't show up on my desk top. It also won't backup my hard drive with time machine. I need help.

Try going to finder preferences, general, make sure show these items on desktop external disks is clicked. You can also go to sidebar (same pane) and click it there so it will show when you open your HD. Time Machine>system preferences>time machine>turn it off click select disk, make sure the correct disk is selected, the turn TM back on. Hope this helps.

How to install Snow Leopard onto external hard drive.

I'm currently running on 10.5.8, and I just bought the Snow Leopard installation disc to update to 10.6.3.
My mac has been running on an external hard drive for about a year. The internal just stopped working.
I want to install Snow Leopard onto my external hard drive, but all of my files are on there, and I read that if I do the install, all of the data will be erased.
If I used time machine to back up the files before I do the install, are they at risk of being erased, since they will be back-uped on the external?
This is probably super obvious, but I want to be very careful with this.
Any help is very much appreciated!
^__^

1. The data won't be erased unless a problem occurs.
2. The Time Machine backup should be on a different drive, as drives can fail.

Using snow leopard on external hard drive w/Mountain Lion OS Mac

I need to use Snow Leopard in order to use some expensive software that will not work in Lion or Mountain Lion. All of our computers have been upgraded to Mountain Lion, whcih doesn't support Rosetta. I was able to install Snow Leopard on an external hard drive and it boots up fine from another computer (that is not mine) that has Snow Leopard as its OS.
But when I boot up from my MacBook Pro (running Mountain Lion) and from my Macbook Air (also running Mountain Lion), I can't seem to do it. I hold the "option" key when starting and I get the option to start from the computer's HD or from the external firewire Snow Leopard drive. When I choose the Snow Leopard drive, it crashes and gives me that black screen with the kernel (?) message in several languages that I need to hold down the Power key to turn off the computer and reboot.
How can I get my MacBook Pro or my MacBook Air to boot up from the Snow Leopard external hard drive? (Once again, it DOES work with a Mac that has Snow Leopard as its OS).

You can't if the Mac is a Late 2011 and later, perhaps if it's a Early 2011 (as some came with 10.6 and some with 10.7) and it should be possible for all Intel Mac's earlier than Early 2011.
Also, like what has occurred in the past, Apple does eventually issues a firmware update in later OS X versions so that earlier OS X versions, despite the Mac previously being able to boot from them, won't any longer. However far as I know Apple hasn't done this quite yet, but will one day.
Baring those issues, if you installed 10.6 on a external drive using a machine specific black/gray disk from another Mac, it has hardware drivers for that model/year of Mac only.
If you used the 10.6 white retail disks from Apple, it only has hardware drivers for all previous Intel Mac's that came originally with 10.6.2 or earlier from the factory. Mac's with 10.6.3 or later on the drive from the factory have different hardware drivers, thus not on the 10.6.3 white retail disk.
To find out what OS X version came on your machines, use the free MacTracker and use your model indentifier in the Apple menu More > Info (aka System Profiler)
So for those Mac's that originally came with 10.6.3 or later, machine specific disks must be gotten from Apple, or if your really talented, it's possible to create a univeral 10.6-10.6.8 install disk by combing the 10.6.3 image with the 10.6.8 combo update which will boot on any Intel Mac if the firmware permits and the hardware drivers are compable.
There is a method to bypass the firmware and install on Mac's that are Early 2011/Late 2011 via Target Disk Mode, or via taking the drive out of the machine as some Late 2011's use the same hardware drivers as the Early 2011 machines (only a processor bump basically)
How to revert your Mac to Snow Leopard
For the MacAir, you can install 10.6 via a USB thumb drive, of course provided it has the hardware drivers.
http://www.maciverse.com/install-os-x-snow-leopard-from-usb-flash-drive.html
So in your case you likely should be rather looking at running Snow Leopard in a virtual machine program in Mountain Lion, which MichealLax over at MacRumors has perfected a technique.
Windows in BootCamp or Virtual Machine?

How do I boot Leopard from external hard drive?

I'm currently staring off into space... my 3 month old MBP seems to have finished its painfully long boot and all that appears the Leopard background. The local Mac guru isn't available until Monday but did tell me I need to boot from my external hard drive. Um, how do I boot from external hard drive?
The cause of the problem: inserting flash drive powering up.
Tried safe boot. Only difference was iCal reminder popped up in space.
Mac guru told me do NOT use install disks!
Help!

Apple support has told me that you cannot boot a MBP from an external drive when Leopard is installed on a MBP.
That is just plain wrong.
1) Hook up your external drive. Use FireWire for better performance.
2) Launch Disk Utility and highlight the actual drive icon at the left. Click on the Partition tab.
3) In the Partition section, click on the Options button. Click on the radio button for "GUID Partition Map". This is the option you must use in order for a drive to be bootable on an Intel based Mac. Click OK.
4) Set up your partitions however you want and click the Partition button at the lower right.
From here, you can either clone your internal drive to the external, or install Leopard on it from scratch.

How to install dmd image from external hard drive to imac with no os installed

I have a G5 iMac that the hard drive crashed. I have replaced the hard drive and now trying to install the 10.5.8 dmd image back from a external hard drive since I don't have a disk. I have not been able to figure how to boot up and install this way.

Neither do I.

Cannot boot Snow Leopard from external FireWire drive

I use a Western Digital My Passport Studio 500 GB external drive to back up my MacBook Pro with Time Machine. I had created a 30 GB Leopard boot partition with various utilities and tools; since the small drive goes wherever the laptop goes, I figured it might come in handy to be able to boot the computer in the event something went wrong with its internal 250 GB drive.
Over the weekend, I upgraded the external drive to Snow Leopard, and now it can no longer be used to boot the laptop. The symptoms are truly weird. Holding down the Option key while rebooting does not show the external drive unless I disconnect and reconnect the FireWire cable. The drive then shows up. I select it, and it appears to begin to boot, then it just sits on the gray screen with the little round thingie turning for a long time (five to ten minutes). Eventually, the system boots from its internal drive. This happens regardless of whether I'm connected by means of FireWire 400 or 800.
After spending a lot of time looking at the usual suspects (cables, permissions, PRAM, etc.) I reinstalled Sand Leopard (OK, 10.5) and lo and behold, the drive boots again (though for some reason I still have to go through the disconnect/reconnect routine). Clearly, something in the OS has changed with respect to the way booting from external drives is handled.
On the positive side, I have none of the symptoms described in other threads: Time Machine works flawlessly, and both the boot partition and the Time Machine partition appear on the Snow Leopard desktop every time I connect the drive.
Does anyone have the same issues? Does anyone know of a workaround?
Thanks,
Daniel

Hi,
Working from a MacBook Pro 2.4 (Santa Rosa) with 4gb ram, running OS 10.5.7-
(All external HDs are 7200 rpm)
Shortly after our fresh install of Snow Leopard onto a new but already tested External 1.5 Seagate Barracuda (with the most current firmware), in an OWC Mercury Elite enclosure-
We installed Snow Leopard smoothly to that external HD without any issues, and it booted up from that 1.5T external HD, and worked fine.
Then, still working from the MacBook Pro, I turned on and booted another external HD (a Newertech Guardian Maximus RAID running 10.4.11 via FW800, daisy chained to the 1.5T External with Snow Leopard newly installed.
Again that's MacBook Pro <FW800> Snowy external HD <FW800> 10.4.11 RAID (booted & working from the RAID).
But when I tried to bootup up Snow Leopard, after doing the work on the 10.4.11 RAID-
It would not boot up.
Though Snowy would appear as an available Start Up disk, each time it was selected as the Boot drive,
the Internal HD OS 10.5.7 booted instead.
I changed around the cables and tried repeatedly.
Same result, no Snowy boot.
Even after the OS 10.4.11 external RAID was power down, and disconnected.
After some looking around, I found this forum:
http://discussions.apple.com/thread.jspa?threadID=2136208&tstart=0
Got me thinking.
I tried the USB, and it booted !
I tried the FW400, and it booted !
And mysteriously, at this point- I tried the FW800, and it booted !
And then, the MBP boots seemed to reliably boot from that external, via FW800.
Bizarre.
Snow Cat needs to be taught originally how to find FW800 from the bottom up ?
Turns out, Snow Leopard doesn't like booting,
if the preceding boot was on the 10.4.11 RAID, and work was done with programs there.
So, once again, I repeated this process:
After working with programs on the 10.4.11 external HD,
the MBP would not boot the Snow Leopard external HD,
it defaulted to booting from the MBP internal HD OS 10.5 via FW800.
even though Snowy was selected for Start Up.
This was the case repeatedly.
(It would also boot from the 10.4.11 external RAID, if it were selected for Start Up.)
(In each of these tests below, I only rebooted the computer at each test. I did no work with programs on the various HDs.)
SO, once again, at this point of the process:
I plugged in that Snowy external HD via FW400,
and it booted up fine !
Then I booted up from the Internal 10.5, and tried to boot Snowy via FW800 again.
It worked !
Then I turned on the 10.4.11 RAID external HD, and tried to reboot from the Snowy external HD.
It worked too !
Then I booted from the 10.4.11 RAID, it came up fine.
Then booted from the Snowy, it came up fine.
Then booted from the Internal HD 10.5, it came up fine.
Then booted from Snowy again, it came up fine.
Then I turned off the 10.4.11 HD, booted from Snowy, it came up fine.
Then booted from the Internal, it came up fine.
Then tried Snowy one last time, it came up fine.
Anyway, the issue is:
It works fine-
Except when I do work within the programs on the 10.4.11 external RAID.
Then I have to use FW400 or USB to get it to boot once again . . .
Regardless of whether the other external HD is removed from the system.
It's some sort of flaw, and totally repeatable in testing.
Hopefully, it will be fixed soon.

Install Snow Leopard on External FW Drive

Snow Leopard will only install on a GUID partition. I usually have two or three separate volumes on my external drive. If I partition my drive prior to Snow Leopard installation, the scheme is Apple partition map and I cannot install Snow Leopard on any volume. So I assume in order to do an install of Leopard, I must install to a single GUID partition because it seems there is no option to make any of the volumes a GUID partition. Am I correct? On this particular drive, I wanted to have a bootable clone
of my MacBook Pro HD, a bootable disk image of my Snow Leopard Install Disk, and a third scratch volume for temporary video storage. What would be my strategy be to accomplish this?

no you can have any number of volumes on a GUID partitioned drive.
select the whole drive (model, not name) in disk utility. click on the partition tab. set the number of partitions to 3 (or whatever), click on options and select GUID. set the formats for each partition, adjust the relative sizes and hit "apply".

this will work just fine once you reformat the drive as above.

Installing snow leopard on new hard drive - disc not seen or found

I can't provide too many details right now as my hard drive is out, and I'm trying to reinstall an operating system.
Problem: Installed a new hard drive purchased from reputable repair store. Last installation disc I have is OS X Snow Leopard. When I get to the point to choose where to install it, it is not seeing the new hard drive. I've double checked that the wires/bar connecting the actual hard drive are snug. Could there be another problem? Something to do with Lion? I've read several forums, but to no avail....
Computer: Macbook Pro unibody. Probably mid 2009.
OS X: The last one before Maverick... 10.8.5
The reason I am putting in a new hard drive is that my computer was having trouble starting up or unexpectedly crashing, although I could do a Safe start or Diagnostic (d). So, on the old hard drive, I did PRAM reset, and Disk Utility, but could not run the Apple Hardware Test, so I took it in. There is a little issue with battery not being full, but they did not think that was causing the problem, and that it was probably a hard drive issue. With the new harddrive... they suggested trying to download an OS from linking to another computer by firewire.... The other computer, (Macbook 2 GHx intel Core 2 Duo, 4 GB 10067 MHZ DDR3, OS 10.8.5) does not have a firewire, but does have thunderport, so I tried doing a Target start to reboot... but Macbook Pro did not read the 2nd computer (Macbook). Then I found my old Snow Leopard disk and here I am...

If the repair store installed the drive, I'd take it back and let them make it work. Take your Snow Leopard DVD also.

MBP Unable to Install Snow Leopard on New Hard Drive

I recently had a hardware failure on a my MBP drive and had to purchase a new one for replacement. I purchased a 320GB Western Digital Scorpio Blue and installed it. I booted from the Snow Leopard disc, and proceeded to do a clean install.
I tried several times, but I continue to receive a "Install Failed" message right as it seems to be completing. I've formatted with Disk Utility from the boot CD as well as via target disk mode. I created a GUID partition, Mac OS Extended Journaled. Didn't work. I also ran Disk Warrior on it via target disk mode. Nothing.
Although it took several hours, I was able to run the Snow Leopard install disc from my MacPro and install it on my MBP with was connected via target disk mode. The install completed successfully, but the MBP will not boot now. I've held the "D" key to force booting from the startup disk, but it either freezes or gives me a kernel panic. Ideas?

From the date you joined the Discussions, (June 2009), I'm wondering if your computer shipped with Leopard (10.5.x) or Snow Leopard (10.6.x)?
If it came with Leopard, you need to boot from the original OS disk(s) that shipped with your computer and do the hard drive install from that version, then do the upgrade.

I downloaded and installed Lion on an external hard drive using my laptop which is running Snow Leopard I have now decided that I want to install Lion on my Laptop, but when I go to the App store and click on my purchases it will not download

I downloaded and installed Lion on an external hard drive using my laptop which is running Snow Leopard I have now decided that I want to install Lion on my Laptop, but when I go to the App store and click on my purchases it will not download again

Thanks Dirk,
Tried your suggestion various ways but it had no effect the download button was still greyed out and the install button would not activate will keep trying to find a solution. I dont want to boot from the external hard drive that has Lion on mainly because it is a usb HD and the connection to my wireless modem slows the connection rate and downloading would take about ten hours

Cannot install Snow Leopard onto external drive

I'm attempting to install Snow Leopard on a second drive, an external bare drive in an Icy Dock enclosure connected to a MacPro (running 10.6.6) via serial port. Apple Disc Utility confirms that the external drive (a Seagate 325gb) has a partition map scheme GUID Partition Table. SMART Status is not supported. Connection Bus reads as SCSI but it's connected with a serial cable.
I'm able to perform the first part of the install by selecting the external drive but when I have to restart and complete the install from the original Snow Leopard disc (10.6), the external drive no longer shows up. I've tried several times and have restarted the Icy Dock external drive enclosure.
Any ideas? Thank you.

Not necessarily. Use a backup utility so that you can deselect all the data from within your Home folder as well as third-party applications in order to create a bootable disk but without some of the excess. Any of the following should be suitable:
Backup Software Recommendations
Carbon Copy Cloner
Data Backup
Deja Vu
Silver Keeper
MimMac
Retrospect
Super Flexible File Synchronizer
SuperDuper!
Synchronize Pro! X
Synk Pro
Synk Standard
Tri-Backup
Others may be found at VersionTracker or MacUpdate.

Install data from external hard drive?

Hi, we have our old macbook data saved on external hard drive (old laptop had water damage but able to retrieve data). I now have new macbook, how do I install data from external hard drive to new macbook? Is it super easy? I didn't want to set up new laptop until I could understand how to install all our old data. Thanks

Do you have the appropriate cable to connect the external drive to to new Macbook?
If you do, the rest is easy. Connect the drive and start up the new Mac. The first steps in the setup will be to enter information about yourself, etc. etc. As you proceed you will be asked if you want to bring in data from another place. Just follow the directions, and the Mac Setup Assistant will do everything for you.
The critical part is making sure the external is corectly connected to the new computer.

If the Mac in your signature is what you desire to use 10.5 with, you can't do so, it is too new.
If PowerPC application compatibility is what you desire with that Mac, look at this solution:
https://discussions.apple.com/docs/DOC-2295#ROSETTALION
10.5 only was distributed by CD and updates to 10.5 from free online downloads. Why do you want 10.5, and what do you desire to put it on? Is the person sending 10.5 using 10.5 for anything? If he is, he can't sell the drive.
