Can you install Mac OS X from external DVD drive?

Hi gang,
My DVD drive in my laptop is busted, so I was hoping to install SL from an external drive. Possible? Also, does the install work using the virtual DVD drive with a MacBook Air?
Cheers!

  • Can't re-install Leopard(10.5) from external DVD-drive...

    I'm trying to wipe my hard drive and re-install OS 10.5.5 from the start up DVD's apple sent me. The internal drive is broken and will not accept discs so I had to buy an external USB DVD drive. When I insert the disc and start the install process the computer restarts and stops doing anything when it gets to the gray Apple screen(there is a spinning dial just under the apple sign). The computer stays there till I turn the computer off.
    Why can't I re-install? I've tried holding the option key on start up but all that comes up is the hard drive icon, when I click on it it goes right to the desktop.
    Is this caused by the External drive?
    Thanks for any help you can give!

    Check this link and see if your Mac fits the requirements (most information can be found in Apple Menu>About this Mac)
    http://support.apple.com/kb/SP575
    If it's the Macbook you have listed in your signature it will run Snow Leo just fine.
    Or just check to see if it has these things:
    Mac computer with an Intel processor
    1GB of memory
    5GB of available disk space
    DVD drive for installation

  • Can I install a program on an External Hard Drive?

    I have an 500 GB external hard drive that I attach to my MBP to store movies and my aperture picture libraries. When I first got it, I created three Mac OS Extended (journaled) partitions, one for movies, one for pictures and the other one for “extras”. I’d like to install Adobe Photoshop on my external hard drive, so I’d like to know if there is a way to make any one of my three partitions operate as if they were a system partition. Can I install an application in an external hard drive? Can I run an application from an external hard drive? Which formatting solution could help me achieve what I want? Is this even possible? Any suggestions?

    There are many applications that are happy to be installed on a partition other than the boot partition. However, if the Adobe Photoshop installer does no present you with that option I wouldn't. You could always copy it across post-installation to see if it will work. Updating my present issues.

  • Can I install OS 9 on an external Firewire drive?

    I am not sure if this belongs in the G5 thread or the Leopard thread. Anyway:
    I have a Mac G5, running Leopard 10.5.4.
    I understand that Leopard will not run Classic applications.
    *However, can I install OS 9 on an external Firewire drive? And just boot directly from that drive?*
    I have essential OS 9 apps that I really need to keep.
    I am aware of Classic emulators that run under Leopard, but that is not an option.
    Any advice, insights, suggestions, et cetera in this matter will be appreciated!

    +PS  I should have added for the sake of others reading this thread…+
    You, Dunestrider, can run your Mac in Tiger (and hence in Classic) because, AFAIK, your G5 originally shipped with Tiger.
    Others should be aware that you cannot boot a Mac with an OS earlier than the one with which it shipped, i.e. if your Mac shipped with Leopard you cannot do what I suggested in my previous post. See this Apple doc.
    Also, Dunestrider, I just realised belatedly that you won't have to buy Tiger - you will still have the original Install disk(s) that came with the G5.

  • Can I install snow leopard on an external hard drive so I can run quicken 2006, and put snow leopard on my imac harddrive

    Can I install snow leopard on an external hard drive in order to run my quicken 2006, and install lion on the hard drive of my imac?

    You don't need to erase the drive and repartition from scratch. You may be able to add a second partition on the fly. The caveat here is that once you do that you cannot create a Windows partition using Boot Camp. Of course if you have no plans for Boot Camp then it isn't relevant.
    To create a second partition on your existing startup volume:
    To resize the drive do the following:
    1. Open Disk Utility and select the drive entry (mfgr.'s ID and size) from the left side list.
    2. Click on the Partition tab in the DU main window. You should see the graphical sizing window showing the existing partitions. A portion may appear as a blue rectangle representing the used space on a partition.
    3. In the lower right corner of the sizing rectangle for each partition is a resizing gadget. Select it with the mouse and move the bottom of the rectangle upwards until you have reduced the existing partition enough to create the desired new volume's size. The space below the resized partition will appear gray. Click on the Apply button and wait until the process has completed.  (Note: You can only make a partition smaller in order to create new free space.)
    4. Click on the [+] button below the sizing window to add a new partition in the gray space you freed up. Give the new volume a name, if you wish, then click on the Apply button. Wait until the process has completed.
    You should now have a new volume on the drive.
    It would be wise to have a backup of your current system as resizing is not necessarily free of risk for data loss.  Your drive must have sufficient contiguous free space for this process to work.
    Now, you cannot add a new partition that exceeds the amount of contiguous free space at the end of the drive. Disk Utility will fail to add the partition if it cannot find sufficient contiguous free space. If that's the case then you will need to follow your state outline - backup, boot from clone, erase internal, repartition internal, restore backup to one of the partitions (or both in your case.)

  • Problem installing OSX 10.4 from Firewire DVD drive

    Hi, I'd be very grateful if anyone can help... I've been trying to install OSX 10.4 from DVD loaded in an external Firewire Lacie DVD drive and haven't been successful yet. I have tried instructing startup from the DVD in System Preferences, holding Option on startup and selecting the DVD and also holding 't' on startup, which I was informed forced startup from an external Firewire device (this resulted in a large Firewire logo floating round the screen but after 10 minutes or so hadn't progressed into full startup). Having read some bits of info found on Apple support I can see there is some issue about installing OSX 10.4 from a DVD drive other than an internal Apple drive (although I can't see any explanation why). Could someone please let me know if there is another way of doing this? – I mainly want to get 10.4 installed because I want to get a new ipod which requires 10.4 rather than 10.3. Thanks very much, Sam

    Some external DVD drives support startup. Some do not.
    Holding down the T key at startup makes the Mac go into FireWire Target Disk Mode. It will not help you start up from the DVD drive.
    If you have another Mac with FireWire and a DVD drive, you can use FireWire Target Disk Mode to mount your Mac's hard drive on the other Mac's desktop. Then, you can use that other Mac to startup from the DVD and run the installer, pointing to your Mac's hard drive for the installation.

    I don't know of any other way, if the external DVD drive does not support start up.

  • Ibook g3 M2453 boot from external DVD drive

    Hi, I'm Simon from Germany.
    I have an iBook M2453 Mac OS X and a lot of dvds.
    But the iBook has no DVD drive. So I bought an external DVD drive. But no matter what I do during boot (press the C key or alt)
    I can not boot from external DVD drive.
    Please help me
    Thank you.
    Simon.
    PS: I have translated the text using Google translate

    Hi Simon,
    the iBook is able to boot from USB, but this is not expected behaviour and not supported by Apple.
    http://support.apple.com/kb/TA20554
    There are some external enclosures that do the trick.
    But only when you press ALT after Power on. (Select a startup volume via the Startup Manager)
    External enclosures with Prolific PL-3507 chipset (Firewire/USB Combo)
    You will find them on Ebay Germany
    I have a Delock IDE>USB 2.0 enclosure for 2,5" HDs
    http://www.delock.com/produkte/gruppen/Geh%C3%A4use/Delock_25_external_enclosure _USB20_42365.html?setLanguage=EN
    that works also.
    Hallo Simon,
    das läuft nur mit einigen wenigen externen Gehäusen. Such auf Ebay nach "PL-3507"
    und nimm eins mit Firewire und USB Anschlüssen.
    Ein Festplattengehäuse von Delock für 2,5" Festplatten ging auch ( Link oben)
    Ein Boot ist nur möglich wenn du die ALT Taste nach dem Einschalten drückst und dann über den Startup manager dein Boot volume auswählst.

  • Installing mac os x from external drive

    I would like to upgrade and older macbook, which is running Mac OS Tiger, to Mac OS X Snow Leopard. My problem is that the DVD drive of the laptop is broken. I shared the DVD drive on my new macbook but for installation to start the old macbook needs to restart. When restarted the installation doesn't begin because the laptop needs to be restart from the installation DVD. Also made an installation (.cdr) copy of the installation DVD and placed it on the old laptop.
    Restarting the laptop causes the same issue as the external DVD drive.
    Is there a way to bypass the restarting for installation to start or is there any other way to upgrade my older Macbook?
    Danny

    You can't use Remote Disc to install an OS; you need to use an external optical drive, or target disk mode, or if you have a computer running Mac OS X Server, NetInstall.

  • Install Windows from external dvd drive?

    ok.there is my problem.
    I have a Mac Pro here.Last week the dvd driver stopped work and I do not have time to fix it now and I need urgently install the windows xp because need to use a specific app for windows.
    Is it possible to install windows xp on bootcamp using a external dvd drive (usb).
    thank you.

    I have the exact same problem - my internal SuperDrive died and I'll be damned if I'm going to pay over $500 to get a new one. It appears to be utterly impossible to install Windows from an external DVD drive. At least it seems to be that way for me and my machine.
    I've tried my drive connected with USB and with Firewire. I've tried rEFIt. I've tried booting with the Option/Alt key. My Mac seems unable (or unwilling) to do this.
    I've found many many people with the same problem and only a very small handful that seem to eventually get it to work.
    I've even tried to use the 30 day trial of VMFusion (which is not a long term solution because it doesn't use/mimic sufficient video drivers to support the games I want to play) to install Windows to the partition and I can't get that to work either. The Windows installer seems to refuse to install an older version of the system when the boot version has already been updated to a new one.
    Does anyone out there have a way to reliably install Windows on a BootCamp partition?
    Cheers,
    Fusilier

  • Installing Mac OS on an external hard drive

    I've had an 80GB Mac Mini for about a year and I absolutely love it. Yet, because I use it so much, during this short time I have quickly maxed out the storage with a large amount of photo and music files. Can I install my current Mac OS on an external hard drive where I will have 4 or 5 times the hard drive space for photos and music and still retain the option of booting to that or my Mini? I had a support tech tell me this was possible, but at the time I wasn't ready to do so.
    Another option would be to store music and photos on the external hard drive such that iTunes and iPhoto will navigate to folders located on this drive instead of the internal Mini hard drive. I'm sure this would be the best option, but I don't know how to do either of the two.
    Would greatly appreciate any assistance and advice. Thanks!

    Since I've gone both routes, I figured I'd chime in. Shortly after buying my mini bought an external firewire (don't even think about USB no matter what the sales drone might tell you) and cloned my system to it. I then created a nicely sized BootCamp partition and used the external for Mac work and the internal for PC work. I kept a small Mac partition on the internal removing everything from the OS and Disk Utilities - basically a fast diagnostic disk. That was a great way to work and a side benefit is that the 7200 RPM external FW drive booted up a bit faster. Disk space taken up? Well, yeah, but how big is an external drive? Besides, there are external drives (and do it yourself cases) made especially for the mini so you can stack them.
    This summer the internal drive started clicking - not a good sign - and so I cloned the PC partition and bought a new internal drive. I've had a fair amount of experience opening minis but I make up at least one new curse every time I do There are a couple mini fan wbesites around so check them out to find out what drives are mini friendly today, check out the instructions, and see if the job is for you. It isn't brain surgery but it is more involved than putting a bandaid on a skinned knee.

  • Can I install my OS on new external dvd/cd drive

    My hard drive died at the same time as my internal cd DVD drive. So I'm thinking of buying the OWC Mercury Pro Dual Layer DVD+/-RW Pioneer DVR-218L
    External DVD/CD Writer (http://eshop.macsales.com/item/OWC/MRF82SD22B/) but need to know if it's going to work automatically. Obviously I can't install it if my OS isn't even installed!

    You can't boot the computer from a external DVD drive.
    If you can find another model Mac just like yours, then c boot off your installer disk and HFS+ format a external drive and install OS X onto it, you can take that and hold option boot the sick Mac from.
    Also once you get the internal drive replaced, you can use that external drive to Carbon Copy Clone the OS right onto the internal drive, no need for a internal DVD drive replacement, then you can use the external DVD drive.

  • Installing from External DVD Drive

    Can you install Leopard from an external DVD drive (USB)? I bought an external DVD drive and it has a faster speed then the built in DVD Drive in my iMac.
    Thanks,
    agent6998

    I wanted to try this out and used my 10GB 3G ipod to install, and it actually went pretty fast. It took me ~45 minutes to install from boot to boot (not counting post-boot blue screen that took ~10 minutes or so, and then final setup tunings/customizations, etc.). The time saved equaled the time it took to copy the DVD to disk image, root around and find my old ipod, and restore the image to the ipod, so its not that much more efficient. Additionally, its an unsupported method of installing, so if something goes wrong dont blame Apple.

  • Installing Windows 7 from external DVD drive

    I removed the internal DVD drive and replaced it with an OCW SSD on my 15" MBP. I used Disk Utility to format it to MS-DOS(FAT). I bought Windows 7 and downloaded the .iso file from the website. I used Disk Utility to burn the .iso image onto the disk. Since BootCamp won't recognize my external DVD drive I installed rEFIt, so after I restarted twice it came up with a prompt to boot from Windows install CD. I click the the icon, the screen goes black, and then the DVD drive stops spooling and I have to hold the power button down to restart it normally. What way is there to install WIndows 7 from an external DVD drive?

    Maybe use Winclone (Mac app)? Others here know more about using Winclone than I do.
    I use Casper (Windows app) for cloning an internal Windows partition to an external drive, so a Casper restore would be just the opposite, but requires a CD drive which you are now lacking.

  • Installing Tiger from external DVD drive

    Hi,
    My internal optical drive is damaged. I would like to install Leopard from an external DVD drive. I currently have Tiger on my system. But nothing happens when I double click on the installation icon. Any suggestions ?

    Boot while pressing the Option key, then select the DVD.

  • Installation from external DVD drive

    I have an older Powermac G4 that had a DVD-RAM drive and I replaced it with a high-speed Toshiba CD-RW drive. Is there a way to install Tiger from the DVD via an external drive or do I have to buy the CD's?

    Assuming this Mac has a Firewire Port or Ports and you have an external Firewire DVD drive and your Mac and the external DVD drive supports booting the computer from the external DVD drive, the answer is yes.
    If not, you need to use Apple's Media Exchange Program and exchange the Tiger DVD media for CD media or if you have access to another Mac with a DVD drive and both Macs support Firewire Target Disk mode, you can connect the two Macs via Firewire Target Disk mode and install Tiger on your PowerMac G4 from the Mac with a DVD drive.
