Cant boot from snow leopard dvd and install crashes computer

Folks, hi, newbie to this forum but at wits end.
I have a MacBook Pro 17inch mid 2010 model. I added the OMG disk doubler and ditched the internal dvd, so I now have 2 X 500GB hard drives, one of which has the OSX. This disk in trouble and Disk Utility says that it needs repairing, but i need to repair after booting from an different disk.
So, I added a usb dvd drive and put in snow leopard. It would not boot via holding down 'c' and the option key only saw the current drive. No problems I thought, I will install onto the second hard drive and boot from that. The process got a fair way though (20 mins) and the computer crashed. I checked that it is GUID, tried again, and ditto. So, I made a new partition that was nice and clean -- and ditto. Stuck about now, I tried to format a usb hard drive -- ditto. Hmm, didnt want to, but out came the second drive and in went the old dvd drive -- same issue -- could not boot using c button and the option key did not recognise the snow leopard install. Out came the drive and I went to the apple store -- they told me that the Snow Leopard I had brought was an upgrade and that I needed a Box Set. $169 later and - you guessed it -- the dvd is the same, no start on c, not recognised on option, and the computer crashes if I try and install to the second hard drive or an external drive.
Help anyone??

when i go to system prefs- startup, the dvd does not show up in the list of startup drives. The apple salesman said that the OSX install disk I purchased was not a start up disk / full install but rather an upgrade only disk. That is why he said to use the box set as a 'full install' - but both appear to not start up or be able to do a clean install. I just end up with a set of files call Mac OSX install files.

IMac will not boot from Snow Leopard DVD or original Leopard disc!

Hey,
I am going mad! I am trying to update my iMac (with original Leopard installed) to Snow Leopard. Here is what I have tried:
Using the Snow Leopard DVD:
- A standard install: the disc ejects after about 15 minutes.
- Put another working DVD in and verified it in Disk Utility, all ok.
- Verified the internal hard drive in Disk Utility, all ok.
- Verfied the SL DVD, all ok.
- Decided to try a clean install, so backed up everything.
- Tried to boot from SL DVD by using the Utilities option, it ejects the disc at restart.
- Tried to force it to boot to the DVD by restarting and holding the C key, it ejects.
- Restart holding the Option key, it ejects.
- Restart holding the Ctrl, Alt and Option keys, ejects.
- Everytime it ejects and starts up normally.
- So I cleaned the disc, updated all the firmware, reset the NVRAM/PRAM via holding keys when restarting, and repaired disc permissions.
- Tried to force it to boot again, ejects.
- Tried to put the disc back in straight after it ejects with all the steps, still starts up normally.
- Changed the start up disc in System Preferences to the SL DVD, restart, it ejects.
By now I am readying the noose...
- Dug out the original Leopard installation CDs.
- Repeated all the forced boot restarts (C key, Option key, Ctrl, Alt, Option keys), same story.
- Repeated changing the start up disc in System Prefs, same story again.
- Call Apple Support, they told me to try everything I have tried and that the DVD drive is dodgy, well it works with everyhting else! Burning and reading! I really don't want to have to go to an Apple Store- it's miles away (a costly journey) and I just do not have the time for all of this.
RAWR! Does anyone know what to do? Please? S.O.S.?

Possible scenarios:
1: The 10.6.3 SL retail disk is bad, it happens.
2: Your not using the 10.6.3 SL retail disk but one from another machine which doesn't have the drivers for that machine.
3: Your optical drive is funky or some other hardware issues.
4: Your trying to install 10.6 onto a PowerPC based Mac, no can do.
5: Your not using a wired keyboard for boot key commands, have some other hardware conflicts.
Possible solutions.
1: Copy the SL 10.6.3 disk using Disk Utility to another DVD, the error checking may resolve the original disk's issue.
http://www.brokenhomeboy.co.uk/pierow/blog/2011/10/make-a-bootable-backup-snow-l eopard-install-disc/
2: Make a SL bootable USB
http://www.maciverse.com/install-os-x-snow-leopard-from-usb-flash-drive.html
3: Call Apple for a new 10.6.3 disk (and make copies for backup before Apple discontinues selling it)
If your upgrading to 10.6 to get to 10.6.8 to upgrade to 10.7, be warned of this:
1: Your 10.5 software will not work in 10.7, no more Rosetta or PPC based code.
2: Your hardware will not qualify if it's a 32 bit Intel Core Duo, also you may experience slowdowns in performance over 10.6 (10.6 is the fastest OS X version for Intel Macs) in older Intel hardware (I suggest Early 2011 Mac's and later only for Lion)
3: Mountain Lion 10.8 is reportingly coming out this summer and will not run on a lot of older Intel based Mac's because of heftier graphics requirements.
4: 10.6 has the widest range of current avaialble software and drivers for third party hardware.
My advice, stick with 10.6.8 and stay there, buy a new Mountain Lion machine after this summer. Skip Lion completely.

Can only boot into Windows 7. Can't even boot from Snow Leopard DVD.

I have no idea what prompted this. I don't recall installing any OS updates recently, other than some Windows Live apps in Windows 7.
I have an early 2009 Mac Mini with Snow Leopard, and have Windows 7 64-bit installed in a Boot Camp partition. When I installed Windows 7, I couldn't get the Boot Camp utility to install within Windows (I guess because it's 64-bit) so to switch back and forth between OSes, I just shut down the Mac and restart it with the Option key pressed, and select Mac OS X when I want to return to Mac. This has worked for about a month and a half now (ever since I got Windows 7). Suddenly I have problems.
I first had problems booting into Windows or Mac. I got to the grey screen with the Apple logo, with that spinning "progress" thing going for a while, then it would freeze up and get stuck on the grey screen with the Apple logo. I zapped the PRAM. No help. Then, after disconnecting all external drives (I have several) and extra USB devices, I was able to boot from the DVD install disk and reinstall Snow Leopard on my internal drive. Joy, or so I thought. Then I booted into Windows 7, and after some weirdness getting it to start, it did successfully start and ran just peachy.
Then I turned off the Mac and held down the option key (as usual) to return to Mac OS. But now all that happens is that I get a grey screen for a few seconds, then the Mac boots back into Windows 7, which seems to work fine. (I'm in Windows 7 right now.) I turned on one my external drives (Snow Leopard installed, connected via Firewire 800) in hopes that the Mac would boot into that, but same thing. Ignored and back to Windows 7.
Then I thought I'd boot from the install DVD again by putting it in the drive and holding down the C key as I restart, but the same thing--a grey screen for a few seconds, and then booting right into Windows 7. I can't seem to escape Windows 7! It's a bit disturbing when it won't even recognize the install DVD.
I tried to call Apple Care since I'm within my 90 day support window, but of course they are closed. I'm figuring that I'm going to have to take this into an Apple Store, but thought I'd see if anyone has any ideas. Any advice will be appreciated. Thanks.

According to Apple, Win 7 64bit is supported with Bootcamp 3.0. If bootcamp 3.0 is available; I could not find it anywhere on Apple's website. It appears the most recent version is 2.2. The only place I could find 3.0 is not on Apples website and it's a questionable source so I won't post it here.
It may just be a matter of time before Apple makes it available. I'm not suggesting you wait, however if the install disk can't be used, I'm not too sure where u could go from there. Calling Applecare might work.
If you do a simple google search using the terms 'download bootcamp drivers windows 7' u will see what I was referring too.
Here's what I found from Apple (It doesn't specifically mention 64bit however just win7): http://support.apple.com/kb/HT3920
This is not from Apple, but specifically addresses whether they support win7 64bit: http://www.macnn.com/articles/09/08/31/boot.camp.win.7.64.support/
Here is more info about bootcamp 3.0 and win7: http://www.apple.com/support/bootcamp/

Cant boot from USB or DVD to install WIN 8.1 ENT

Hello,
Im currently evaluating a Thinkpad tablet 10 at work. The installed OS is atm 8.1 Pro but we have to reinstall with 8.1 Enterprice in order to get everything to work within our network.
But this have been more difficult than i thought. Im totally unable to bot from USB or DVD.
To sum up:
- Made bootable usb win 8.1 ent (fat32) with Rufus
- Made bootable dvd with PowerISO
Both works perfect in an ordinarie PC.
- Mainly booting from computersettings/reset/advanced start/use unit.
- Changed boot order in BIOS
- Toggled safe boot on/off
- Tried usb hdd / usb fdd / usb cd/dvd / etc
Whatever i choose - i reach the ordinarie win-login page.
- Updated bios to latest version
Whatever i do - No boot reaction at all.
Hope I will get some answers so that we can use this tablet.
//Andreas

Did you ever get this to work? I even made the Diag USB with the tablet 10 special code - and when I select the USB device for boot, screen goes black for a few seconds - then back to the menu.
I can't boot a default win 8.1 Pro CD either (with a lenovo USB drive).
I tried win10 and it pooched my system - does not boot at all, so I need to boot of an external device.

Can't Install Boot Camp from Snow Leopard DVD in Windows 7

I have an iMac "Core 2 Duo" 3.06 24-inc (08) running 10.6.2 and Windows 7.
I was able to successfully use the Boot Camp Assistant to partition and install Windows 7 on my iMac. After the installation, I was able to download updates from Windows Updates which included video drivers.
However, when I inserted my Snow Leopard DVD to install Boot Camp 3.0, the Setup.exe only gave me two options: To Install Mac OS X remotely and to install CD/DVD Sharing. I was not presented any options to install Boot Camp.
I did manually navigate the Snow Leopard DVD and found a Boot Camp directory with its own setup.exe and when I clicked on it, it gave me an Installation Error stating "Boot Camp x64 is unsupported on this computer model". I did some research and I found no mention of my iMac listed as an unsupported model.
Any help would be appreciated.

When I inserted Snow Leopard DVD, the autorun didn't show me an option to install Boot Camp Drivers. Just like the author of this topic, it only showed me 2 options: to Install Mac OS X remotely and to install CD/DVD Sharing.
Then, I've run Windows Explorer, navigated to Snow Leopard DVD, opened Boot Camp folder and runned "setup.exe". The installer opened and Boot Camp 3.0 was installed successfully.
I don't know if it could help you guys with that error message, but after the installation of Windows 7 64bits, I've rebooted my Macbook Pro. Only after the reboot I did the Boot Camp Drivers installation.
You can also try to run the "setup.exe" as Administrator (right-click, Run as administrator).
Also, my Snow Leopard DVD is that grey one with the white "Mac OS X Install DVD" labelled on it.

Replaced faulty hard drive now can't boot from Snow Leopard.

Hi there,
As it says I replaced my internal WD 250gb drive in my late 2006 2.16ghz imac . I followed the tutorials on the net to the tee yet upon trying to boot from Snow Leopard after firing it back up all I get is the Apple logo and the timer . I've tried holding C to no avail . I've held Alt to select the OSX disc yet it still won't boot to get me to Disc Utility . I've even put the old hard drive back in . When I hold Alt on start up it shows the drive and the disc but will boot from neither when selected . I've tried to get the Snow Leopard disc to eject so I can try my originals but it won't even do that . I'm convinced I haven't damaged anything but I'm at my wits end ! Does anybody have any ideas how to get the Leopard disc out so I can at least try from my originals ? The drive I've installed is compatible it's a 1tb WD . I also triple checked all the connections and they all seam sound . Really appreciate your help lads as I wanted to give the iMac to my daughter when we get a new one .

You will first need to prep the new drive using Disk Utility on the original 10.4 Disc or Retail upgrade 10.6 DVD. It needs to be Partition GUID Partition Table and Format it Mac OS Extented (Journaled) before you can install and run OS X on it.
1. Boot from your SL install DVD or Bootable Clone and open Disk Utility.
2. Highlight the new HD in the list of drives and select the Partition tab.
3. Under Volume Scheme select 1 Partition and click on the Options... button.
4. Select GUID Partition Table in the drop down window and click OK.
5. Set the Format to Mac OS Extended (Journaled) and click the Apply button.
6. Once thats done, then you can do a clean Install, Restore from TM or a Bootable Clone.

Why can't brand new MacBookPro9,1 (OEM Mountain-Lion) boot from Snow Leopard on external drive, or internal partition?

Why can't brand new MacBookPro9,1 (OEM Mountain-Lion) boot from Snow Leopard on external drive, or internal partition?
Is this because of hardware changes? Or firmware changes? Or is it just and Apple Inc. administrative fiat?

@Steve Holton: Sorry Steve, but you're wrong about that one . I'm using 10.8 (purchased and downloaded) on the internal HD of this MBP8,3 (2.2 GHz, 17"), and I am also able to boot into 10.7.4 and 10.6.8 from external FW800 partitions.
However, I DO have problems with my MBP9,1. It came with 10.7.4 installed and ran fine. Then I purchased and installed 10.8. It ran fine but could no longer boot from 10.7.4 on an external partition. I then reinstalled 10.7.4 on the internal HD and discovered that it is still unable to boot (even 10.7.4) from an external FW800 partition.
One of Apple's Senior Support Advisors has done some remote troubleshooting but the case is still open and unresolved. An earlier Apple Support case suggested that when, I installed the downloaded copy of 10.8, there had been a "firmware update" (behind the scenes) that is now causing the problems with booting from my external partition(s). This apparently is "a bug": it is not what is supposed to happen.
So - I believe - "the problem" really has nothing to do with hardware capability. It is strictly about Apple's strategy for "managing its future customer base". If you don't like it - use something else - I am seriously considering Ubuntu as an alternative.
If there's a hidden caveat in all this it's probably "Read Appple's Licence Agreement VERY Carefully".

If I upgrade my Mac mini to Lion, can I still boot from Snow Leopard on another drive/partition?

If I upgrade my Mac mini to Lion, can I still boot from Snow Leopard if it is on another partition/drive?

Yes

I am in the process of updating the os of my macbook pro and have installed from the snow leopard dvd and did the 10.6.8 combo v1.1 as well and wis to update further but i now cannot get preview so i am concerned about going forward. how to get prev

I am updating the OS on my MacBook Pro from 10.5.8. I have installed 10.6.8 and the 10.6.8 combo v1.1. I cannot open my older version of Preview and do not appear to have a newer version which i thought would be on the Snow Leopard dvd. How can I get the correct version of Preview and is it advisable to upgrade to OS7 andOS8?

It is always installed with whatever new version of OS X is installed or appropriate updates. Since you plan to go forward your choice depends on your model. I would urge you to perform a clean install instead of continuing the upgrade path which may interject incompatibilities.
Upgrading to Yosemite
You can upgrade to Yosemite from Lion or directly from Snow Leopard. Yosemite can be downloaded from the Mac App Store for FREE.
Upgrading to Yosemite
To upgrade to Yosemite you must have Snow Leopard 10.6.8 or Lion installed. Download Yosemite from the App Store. Sign in using your Apple ID. Yosemite is free. The file is quite large, over 5 GBs, so allow some time to download. It would be preferable to use Ethernet because it is nearly four times faster than wireless.
    OS X Mavericks/Yosemite - System Requirements
    Macs that can be upgraded to OS X Yosemite
         1. iMac (Mid 2007 or newer) - Model Identifier 7,1 or later
         2. MacBook (Late 2008 Aluminum, or Early 2009 or newer) - Model Identifier 5,1 or later
         3. MacBook Pro (Mid/Late 2007 or newer) - Model Identifier 3,1 or later
         4. MacBook Air (Late 2008 or newer) - Model Identifier 2,1 or later
         5. Mac mini (Early 2009 or newer) - Model Identifier 3,1 or later
         6. Mac Pro (Early 2008 or newer) - Model Identifier 3,1 or later
         7. Xserve (Early 2009) - Model Identifier 3,1 or later
To find the model identifier open System Profiler in the Utilities folder. It's displayed in the panel on the right.
     Are my applications compatible?
         See App Compatibility Table - RoaringApps.
Upgrading to Lion
If your computer does not meet the requirements to install Yosemite, it may still meet the requirements to install Lion.
You can purchase Lion at the Online Apple Store. The cost is $19.99 (as it was before) plus tax. It's a download. You will get an email containing a redemption code that you then use at the Mac App Store to download Lion. Save a copy of that installer to your Downloads folder because the installer deletes itself at the end of the installation.
     Lion System Requirements
       1. Mac computer with an Intel Core 2 Duo, Core i3, Core i5, Core i7,
           or Xeon processor
       2. 2GB of memory
       3. OS X v10.6.6 or later (v10.6.8 recommended)
       4. 7GB of available space
       5. Some features require an Apple ID; terms apply.
Before attempting a clean install you want to first download the appropriate installer application from the App Store. It will download into your Applications folder. You need to make a copy of it in your Downloads folder so you can make a bootable USB flash drive:
Make Your Own Mavericks, Mountain/Lion Installer
After downloading the installer you must first save the Install Mac OS X application. After the installer downloads DO NOT click on the Install button. Go to your Applications folder and make a copy of the installer. Move the copy into your Downloads folder. Now you can click on the Install button. You must do this because the installer deletes itself automatically when it finishes installing.
   2. Get a USB flash drive that is at least 8 GBs. Prep this flash drive as follows:
Open Disk Utility in your Utilities folder.
After DU loads select your flash drive (this is the entry with the mfgr.'s ID and size) from the leftside list. 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.
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.
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.
Click on the Erase button. The format process can take up to an hour depending upon the flash drive size.
Use DiskMaker X to put your installer clone onto the USB flash drive.
Make your own Yosemite flash drive installer using the Yosemite tool:
You can also create a Yosemite flash drive installer via the Terminal. Yosemite has its own built-in installer maker you use via the Terminal:

Can't boot from System 9 CD and install System 9 over 10.4

Power Mac G4 450 APG Mac OS X (10.4.8) 896mb RAM
I got my Mom's old G4 and am trying to set it up for use by my daughter (I like the OS 10 parental controls but not my 6 year old using my PowerBook...)
I did a clean install of System 10.4 and was able to update it to 10.4.8 however since I erased the disk, only System 10 is loaded with no System 9 available for Classic mode. When I try to boot up from a System 9.2.1 installation CD, it will normally not even boot from that CD (I have been able to boot from a System 10 and a Disk Warrior CD).
When I try to boot from the System 9.2.1 CD, the monitor usually shows a blank screen with the mouse arrow (which moves with the mouse). I have to hit the reset button to boot back into 10 or try holding the "C" key down again. I've tried two System 9.2.1 CDs and a System 9.0 CD with no luck.
I've reset the NVRAM, PRAM, PMU etc. I was able to get a System 9.2 boot up screen three times (by hitting the reset button and holding down the "C" key) but the system loads only about half way on the horizontal bar and shows only 3 startup icons on the bottom. It then stops.
I've also tried dragging the "System" file out of "System/Library/CoreServices" to the desk top but that did not help. Found that the system recreated the file back in its proper place.
Anyone have any ideas?

PowerBook 15 G4 1.5 Ghz Mac OS X (10.4.8) 1.5mb RAM

The first line of my original post had: Power Mac G4 450 APG Mac OS X (10.4.8) 896mb RAM. What it did not have was that there was a SCSI card attached to an internal SCSI HD that I pulled out of an old PowerMac9500 (I wanted some of the data and applications on it).
When I pulled out the SCSI card, I was able to boot from the 9.2.1 CD and install System 9 onto one of the ATA drives I had installed (the original 20 gb HD and a 30 gb HD from an old PC). All three drives did show up on the desktop and I had access to all as they were. I just could not boot up from the System 9 CD. Pulling out the SCSI card allowed me to boot from the System 9.2 CD. I don’t know why. I installed System 9 with a clean install (erasing all files on the original 20 gb HD), rebooted into System 9, then updated the firmware successfully. I then loaded System 10.4.8 on the G4.
I now have System 10.4.8 running on the G4 with System 9.2 running in Classic. All three HD’s are working fine. Now if I can only figure out why I can’t hook up an external Ultra SCSI 2 CD-RW but that will be another post.
Thanks to all,

Late 2008 mbp - installed new ssd - trying to boot from snow leopard iso on flash drive - says 'cannot install mac os on this computer'

Hello -
I just installed a new M500 Crucial ssd in my late 2008 mbp - everything was working fine on old hard drive (running snow leopard) but was getting slow and wanted to upgrade - i lost my snow leopard disk when moving from hawaii so i found an iso online - using a flash drive i partitioned the disk and made the bootable image on flash drive - formatted as extended/journaled - switched out the hard drives - plugged in the flash drive - started the comp - held option - install begins to boot - choose language - all is fine - choose english - next step window pops up saying 'cannot install os on this computer' - click on utility but all options are greyed out - disk util is greyed out - only options it gives is to start from backup or restart - real confused here - all help appreciated - thanks in advance and happy new year!

Snow Leopard comes in discs only. The USB drive may be a counterfeit and/or corrupt. There are two options for you:
Get replacement original OSX installation disks from Apple customer service. Have your MBP serial number ready and there is a charge.
Or two, purchase a Snow Leopard disk from the Apple online store:

Ciao.

My Macpro Intel Core Duo-running OS 10.6.8 has been crashing pretty much with everything I try to open. I find the last resort will be to boot from Snow Leopard system disc. Has anyone experienced this? I can only run Google Chrome.

In the last few days, it seems that my computer has all of a sudden caught a virus. I have never had that happened to a computer, but I have surely heard about it. I can't think of any other reason it is behaving like this. I know that Macs have been pretty much impervious to viruses, but that was before they were the majority of users.
Anyway, what is happening is, my computer keeps crashing whenever I try to open a program, app, document, folder, file, etc. I tried to boot from Drive Genius to establish the problem, but Drive Genius crashed too. I know the last ditch effort (after cleaning and maintenance of disc verification and permissions and repairs, is to reboot from the system disc.
Before I go there I was hoping someone in the community would have a suggestion to help me avoid that ultimate last resort. The tech support guy at Drive Genius told me that probably would have to be the way to go (as in reboot) and if that doesn't clear it up, it's repair time.
Thank you for your consideration in advance;
Lorain R

In the last few days, it seems that my computer has all of a sudden caught a virus.
As others have pointed out, this isn't malware. That should not be your first (or even fifty-first) thought when your Mac starts misbehaving. For more on this topic, see my Mac Malware Guide.
I know the last ditch effort (after cleaning and maintenance of disc verification and permissions and repairs, is to reboot from the system disc.
You mention "cleaning and maintenance." Have you been running utilities claiming to do those things? If so, you may be the victim of an overly-zealous cleaning job, which has removed important files and damaged your system.
If I'm understanding correctly, you're unable to open any applications at all... is that right? Do you have any backups? If you don't have backups, you're in a sticky situation, as it will be difficult to make backups in your current state, but you shouldn't try any kind of repairs without them. (Actually, you shouldn't do anything with your computer without backups, but this is especially important when something is going badly wrong.)
If you have backups, reboot from your Snow Leopard install disc. From there, first, repair the hard drive with Disk Utility. Once that is done, assuming repairs were successful, reinstall the system. You can simply reinstall it on top of your current system, and it will replace any damaged or lost system files with new copies. (You'll also need to update the system via Software Update after reinstalling.)
If you don't have backups, or if Disk Utility can't repair damage, or if the problem continues even after a reinstall, post back with those details.

Can't Boot from Snow Leopard Partition

I have a Macbook Pro from 2008. It previously just had one partition, with Lion on it.
I created a new partition for Snow Leopard
I installed Snow leopard from a retail disk on the second partition. The installation went fine, and I got the message at the end that the installation was successful, and to restart the computer.
When I restart it, it just goes to the gray Apple screen, with the spinning gear, and never gets farther than that. The gear is spinning.
I can still boot successfully into Lion. Once I booted into Lion, I chose the Snow Leopard partition as the Startup Disk, but the same thing happens - just the gray Apple screen and spinning gear. I've let the machine sit for half an hour in that state, but it still does nothing but the spinning gear.
Any ideas on why I can't boot successfully into Snow Leopard and how I can fix it?
Thanks.

I already knew that I'm free to follow my own course, but thanks for giving me your permission (???)
And would knowing the original OS of the machine make any difference in your "advice"? If it was originally Leopard, would that make it any different than if it was Tiger? Answer: No, because you don't understand the problem, and you don't know how to fix it.
Thanks.

Can't boot from snow leopard bootable hard drive on my new 27 imac

Hey guys
I have just bought a new 27in Imac with all possible upgrades.
I have an old 2.2 MBP running snow leopard. I used carbon copy clone to make a bootable clone.
It will boot from the hard drive on my MBP ( the one I cloned it from) but it will not boot on my Imac.
I can select it from the boot screen ( holding down alt) but after I select it I just get the apple logo and nothing happens.
Can anyone shed some light on this for me? I have looked through tones of forums but can't seem to fine the answer.
Will the new mountain lion not boot snow leopard? If it can boot windows I don't see why it wouldn't boot my clone.
Thanks in advance peeps

I don't think it is fixable. Your new Mac has come installed with Mountain Lion. My understanding, from what I've learned on these boards, is that a Mac cannot boot from an OS earlier than the one that was installed at point of manufacture. I believe it is to do with the firmware that is on later models.
It also means that you cannot install an OS earlier than the one the machine came with (apparently this can be worked around by installing an earlier OS in a Virtual Machine, like some people install Windows on their Macs. This is not something I've done, but a regualr poster on here MichaelLAX, I think, has described how it's possible).
If you're wanting to just erase and start afresh with the MBP surely you can do that with the clone? You don't need the iMac to do that.

Will Late 2013 iMac boot from Snow Leopard External Drive?

Hey gang-
Got a new late-2013 iMac for Christmas (yayyyy!!)
I plan on running Mavericks for day-to-day use, but there are a few old Power PC apps that I occasionally need to run. Does anyone know if the new iMacs will boot from an external drive running Snow Leopard? I have an external Firewire drive with Snow Leopard on it and I'm wondering if the new iMac will boot from it if needed.
Thanks!
Dave

Thanks gang. No worries- I keep an older Intel MacBook with Snow Leopard on it and I suppose it will do in a pinch.
Cheers!
Dave
