Os install w/ external cd drive

I had to replace the internal cd/dvd drive with a usb pulg n play external. If I do a clean install of the OS, and reformat the hard drive, will the computer recognize the external drive? so it can read the install CD?
Thanks,
-Adam

Sure. But you will have to use OPTION boot in order to start from it. Be sure to put the DVD in the drive, then:
Boot Using OPTION key:
  1. Restart the computer.
  2. Immediately after the chime press and hold down the
      "OPTION" key.
  3. Release the key when the boot manager appears.
  4. Select the disc icon of the DVD.
  5. Click on the arrow button below the icon.

    Buy an external FireWire drive (and FireWire cable if you don't have a spare or the drive doesn't come with one). Then, just plug it in. Not much for installing.
    If you mean replacing your internal drive, that's another matter entirely.

    Is this a new external drive you are trying to set up for the first time?
    If so, connect it to the Mac, launch Disk Utility in the Utilities folder and format it as noted here:

  • Safari crashes after installing iomega external hard drive

    I've just installed the iomega desktop external hard drive with firewire and usb 2.0. I'm presently connected to my computer by the USB port. Everytime I go to access Safari or Mail they quit on me after a few seconds. I've now disconnected the drive from my computer and it's fine. I did to a Disk Utility repair after the installation but that didn't help. Is there something I neglected to do? Is there a problem between Mac and Iomega? Should I use the firewire instead?

    Are you saying that your internal HD doesn't have an operating system on it either, meaning you can't boot your iMac at all? Or that the external was also named "Macintosh HD" in which case, having been erased and reformatted (hopefully with a GUID partition table), you'll need to clone your internal to it once again.

  • Mac OS X won't install on external FW drive.

    I recently purchased a new Intel iMac and I wanted to use the backup FireWire drive I had been using with my previous computer as an emergency startup disk incase something were to go wrong with the main HD. When I had used the FW drive in this capacity with my PowerBook, it worked just fine; I installed the OS (10.3.9) and was able to start up from the drive itself. However, after attaching the drive to the iMac and attempting to install a minimum system from the OS (10.4.4) install CD, it prevented me from selecting the FireWire drive with a message saying that this was not possible because the computer cannot start up from the external FW drive.
    Why is this? Did something change between 10.3.9 and 10.4.4 to prevent this? Or is it something specific to the iMac itself?
    20" iMac (Intel Core Duo)   Mac OS X (10.4.7)   2.0GHz, 1GB RAM, 250GB HD

    Your external drive must be re-partitioned using the GUID partition scheme in order to install a bootable system on it. Be sure to use the Disk Utility that came with your Intel Mac. Select the hard drive from the left side list, click on the Partition tab in the DU main window. Select the partition numbers, then click on the Option button. Select the GUID partition scheme and click OK. Now click on the Partition button. After the volume mounts on the Desktop select it in the DU left side list, click on the Erase tab in the DU main window. Click on the Options button and select the option to Zero Data (one pass) and click OK. Now click on the Erase button. The format process could take from 30 minutes to several hours depending upon the size of the drive.

  • Mountain Lion is missing, after installing an external hard drive and Carbon Copy Clone.

    I have a mid-2007 desktop iMac Model MA877LL, 2.4 ghz/1gb/320gb, with 4 GB memory, upgraded to Mountain Lion 9/7/2012 at an Apple store (now 10.8.5).  I just installed a new external hard drive Fantom Drive 1T G-Force Mega Disk Firewire 800, then installed Carbon Copy Clone successfully.  However, I could not get the clone to boot from the backup volume.  Mountain Lion showed in both Macintosh HD and External Hard Drive at that point.  After working through many steps with CCC, trying to get it to boot, the final suggestion was to try installing Mountain Lion onto the backup disk via the Mac App Store Installer.   As my Mountain Lion was installed at an Apple store, there's no record of it on line and I can't find an installer, although I've been doing updates as they're issued.  Per article, "OS X:  Installing OS X on an external volume", I erased and reformatted the storage device.  Now, checking my Macintosh HD, Mountain Lion is gone.  How do I get it back?

  • Blue Screen Result When Installing To External Firewire Drive

    I can't afford to have problems with programs not running on Leopard on my 17" G4 1.67 GHz 2 GB RAM PowerBook so I am trying to install it on an external Firewire drive. I was hoping to test out Leopard with certain applications by running it from the external drive.
    The Firewire drive has two partitions, one has my backup clone of the PowerBook and the other just has files and about 35 GB of free space. The installation would be a new installation so none of the files that deal with login or Application Enhancer that are being talked about in other threads are an issue.
    My first attempt to install brought up a blue screen after the installation restart. I left it there for about 30 minutes then powered off the PowerBook by holding down the power button. I started it again and held down the option key, picked the install disk as startup, went through the disk utility repair disk (found no problems). After that I picked the new install on the external from the startup preferences and it simply restarted to a blue screen. I left that one for about 20 minutes then powered down.
    I went back to the Powerbook Tiger OS system, deleted all the installed folders on the external and tried a completely new install. Once again it went to the blue screen after the Leopard install restart. This time I left it overnight and this morning the display was dark and upon waking it up with a tap of the space bar was greeted by the bluescreen again.
    I talked to my Apple hardware rep who knows the equipment that I am working with and we talked about all the steps I went through and he has no explanation why it won't work on the external.
    I would love to hear from anyone that may have insight for this particular external FW drive installation perspective.

    Joe-
    Is the drive partitioned to APM? (Sorry I took Anton's reply to be yours.) What was the type fo partitioning onthe disk with the success? I am not knowledgable enough in those error messages on the system.log file, but one thought is - after the memory upgrade, did you clear the PRAM (long shot, but do it anyway)? The machine booting on one external Firewire drive (#2) implies the problem is with the external FW disk (#1) you are using. Some other people had the bus error, but with Time Machine. (Not to go on a tangent, but TM seems to have problems when the disk name has non-alphanumeric in it.)
    Hoping someone who knows the syslog errors and the boot sequence will pipe in here.

  • Installing on External Firewire Drive

    Hi-
    My Mac has started doing some funny things recently; I cant connect any USB devices, MobileMe refuses to let me delete any items from my iCal and other little irritations.
    I have an external 4Tb Firewire Drive which has loads of space on it free, so I want to do a complete re-install of OS X and boot from from the external drive. I can then reinstall my apps and stuff bit by bit and see what is causing the problems.
    The question is: when I install the system onto the FW drive, will it erase what is already on there? I have some important work on it and don’t want to lose it! Does the installer need a ‘clean’ disc to install?
    Thanks, Andy

    Disk utility's Restore function (and other copying apps such as CCC) will make a bootable installation of Snow Leopard on an external firewire drive that already contains data. Just remember not to check the erase disk option for the firewire drive.
    It's most convenient if you first collect all your user material on the firewire drive into one folder. And there is possibly a risk of something bad happening if some files in your user material have names identical to the names of files in the Snow Leopard installation. That may be unlikely. But you'll have to judge that.
    If that worries you, before you do the Snow Leopard installation on your firewire drive, you can use disk utility to repartition your external drive without erasing any of its data. See this: http://www.peachpit.com/articles/article.aspx?p=1395749. With such a large firewire drive, a number of partitions would seem desirable.
    Then you can install a bootable Snow Leopard on an empty partition of the firewire drive for which you do check the erase disk option. With that option checked, the copy is performed as a block by block copy. Otherwise it's performed as a file by file copy. The block by block copy goes faster and is supposed to be identical in all respects to the original. That's not so with the file by file copy -- though both provide equal functionality.
    Your firewire drive should be partitioned GUID. You can use APM (and the copy will still be bootable) but you will not be able (I've read) to install Snow Leopard updates. You can't, alas, change the partitioning scheme without erasing your firewire 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.

  • ITunes New Install into External Hard Drive

    Hi There!
    I downloaded itunes (itunes.dmg) install from the Apple site & when I tried to open it into my external hard drive, the disk utility window opens up. I've always had problems opening up downloads from emails & other sources & must be needing something in addition to open them up properly. My Windows computer easily opens anything up. WHAT ADDITIONAL SOFTWARE IS RECOMMENDED TO PROPERLY OPEN UP DOWNLOADS/ATTACHMENTS?
    Thanks.
    Rick

    when I tried to open it into my external hard drive
    What does that mean?
    You should not need any other programs to open typical downloads. A .dmg file is as typical as it gets on a Mac.
    If you double-click on a .dmg file and Disk Utility opens up, you may have inadvertently assigned .dmg files to be opened by Disk Utility. Try this. Right (control) click on the .dmg file. Select Get Info from the contextual menu. In the Get Info window, look down to where it says Open with. It should say DiskImageMounter. If it does not, select DiskImageMounter. Then click Change All... button to make all .dmg files open correctly.

  • Application install onto external Firewire drive

    hi,
    I have an external firewire drive and was wondering why I cannot install some applications to this drive. I would like to do this to keep the main disk as free as possible.
    Some apps don't seem to care where they are installed and some do, so there must be some way to do this. And this is place to get that answer!!
    Thanks in advance!!
    BCA

    Oops. I meant Alias instead of link.
    Create a directory on the external called Applications then select it and choose File -> Make Alias in the finder. Replace the Applications folder on your main drive with the alias you just created (this might require admin rights) and then the Applications directory will always reference the directory on the firewire drive.
    You probably want to move the contents of the original Applications folder to the firewire drive before replacing it with the alias or you'll have to reinstall.

  • Install from external DVD drive

    can i install Tiger from my external DVD firewire drive? how would i do this, it is my Imac G3 600 and it does not have a DVD drive built in.
    Xelapond

    Yes, as long as the drive is bootable you can install Tiger from it.
    Insert the Tiger DVD into the drive then restart the computer. After the chime press and hold down the OPTION key until the boot manager screen appears. If the external drive is bootable you should see an icon for it. Select the icon then click on the large right arrow button.
    If the above doesn't work, then insert the DVD in the drive while already booted into your current system. Open the Startup Disk preference and select the DVD from the icon list, then click on the Restart button.
    If the external drive is a bootable drive one of the above methods should work for you.
