How to install lion cleaning the hard drive

I have a MacBook I am currently running Liuon but have previously installed Leopard and Snow Leopard without clearing the hard drive first.
The machine has now three operating systems installed and is running very slow.
It has been suggested that I make a copy of the hard drive, before erasing all the information and loading Lion on a clean hard drive.
How do i do this?

Install Lion to a blank drive or partition, including one created with the Disk Utility, and then either use the Migration Assistant or copy your files to the new system manually as desired.

  • Installing Lion clean on hard drive with multiple partitions

    I have a spring 2008 24" iMac running Snow Leopard.
    I am about to put a new 2TB hard drive in it and after I do that I want to do a clean install of Lion on it.
    I do not want to upgrade my Snow Leopard install to Lion. I will keep it on my back up drive as a fallback incase of serious workflow incompatiblities with the new OS.
    For my workflow I create and use multiple partitions (Mac OS,  Windows and multiple HFS+ for data) on my hard drive and I have seen that Lion creates it's own hidden recovery partition as well for the recovery functionality.
    My questions are:
    1) Will I have issues running Lion on a partition on a hard drive with multiple partitions that have different file systems?
    2) If I install Lion into one of these partitions will it create it's recovery partition within the space of the partition it is being installed into?
    3) I will be creating a clean install by downloading Lion using the App Store and then burning an installer DVD using instructions I found elsewhere and then using that to do the install on the new drive. Is that the best route to take?
    All my current data I will have on a backup external hard drive and after I complete the Lion install on the new larger drive I will manually reinstall all my software and move my data back from my backup drive to the new drive one partition at a time except of course for OS partition. I keep all my real user data outside of that partition anyway.

    I believe this article answers most of your questions.

    You will most likely run into the error message that "Some features of Mac OS X Lion are not supported for the disk" if you have multiple partitions set up, especially if they were not set up using Bootcamp and/or have serveral different file systems.
    You can confirm that the Recovery Partition will not be installed by checking Disk Utility for your current partition map scheme.
    This is most definitely not the end of the world as it is quite easy to create an external Recovery disk.
    1) No, you shouldn't have issues running Lion, but Recovery HD will not be created.
    2) No, and in your case it doesn't sound like it will be installed on your internal drive at all.
    3) Yes. If you begin with an empty partition, then install Lion that would be considered a clean install.
    Hope that helps.

  • How can I completely wipe the hard drive with out the Mac OS X disc? I don't need any of the info on the computer.

    How can I completely wipe the hard drive with out the Mac OS X disc? I don't need any of the info on the computer.

    You can't unless you have a bootable system on an external drive you can use. Otherwise, you need either the original disc that came with your computer or a retail copy of Snow Leopard DVD. The latter contains 10.6.3, so your model must be capable of booting from that or an earlier version of OS X.
    You can purchase replacement discs from Apple:
    Apple Store Customer Service at 1-800-676-2775 or visit online Help for more information.
    To contact product and tech support: Apple - Support - Contact Apple Support.
    You can purchase Snow Leopard through the Apple Store: Mac OS X 10.6 Snow Leopard - Apple Store (U.S.). The price is $19.99 plus tax. You will be sent physical media by mail after placing your order.
    After you install Snow Leopard you will have to download and install the Mac OS X 10.6.8 Update Combo v1.1 to update Snow Leopard to 10.6.8 and give you access to the App Store. Access to the App Store enables you to download Mountain Lion if your computer meets the requirements.

  • How can my daughter use the hard drive in the Time Capsule ...

    So, I am in Oklahoma and my daughter is in Tennessee...
    She has a Time Capsule where the Wi-fi base station quit working, but the hard drive may be OK.
    She bought an Airport Express to use as a wi-fi router.
    The question, then, is:
    How can my daughter use the hard drive in the Time Capsule to do Time Machine backups?
    Thank you very much for your insights.
    Roberto

    It can be done but is very messy. That is assuming the TC is still functional which I kind of doubt.. the wifi is seldom the only thing that will die .. so whatever problems it has the wifi would be the least of it.
    Anyway.. do a factory reset to get started.
    The Factory Reset Gen1-4.
    Unplug your TC. Hold in reset. and power the TC back on.. without releasing reset for about 10sec. When the status light flashes rapidly; release it.
    Be Gentle! Feel the switch click on. It has a positive feel..  add no more pressure after that.
    TC will reboot after a couple of minutes with default factory settings and will wipe out previous configurations.
    No files are deleted on the hard disk.. No reset of the TC deletes files.. to do that you use erase from the airport utility.
    If the LED is not lit then the TC is dead, not just the wireless.
    The setup for using the TC is explained in the bottom of this thread.
    TC in a second local network.
    https://discussions.apple.com/thread/4817218?tstart=30
    The idea is to set the TC to provide router function.. and the computer plugged in by ethernet to as a second network.. but there are rules on how this is done which I have explained in that thread.
    I notice that Mountain Lion deals better with order of network priority than Snow Leopard used to .. so it might not need to have manually set gateway and dns.. although I would still recommend it. It simply stops the second network causing issues.
    It is much easier to simply purchase an external drive and plug that in.
    It is cheaper, faster and more reliable than using the TC for TM anyway.
    Plus a lot of the later machines no longer have ethernet ports.. and using dongles is far from neat.. although thunderbolt to ethernet is IMHO necessary accessory for anyone without ethernet.

    I just bought an iMac G5 with iSight. How do I wipe the hard drive and set it up as a new iMac

    Boot from your Mac OS X installer DVD.  After selecting a language, choose "Disk Utility" from the menu bar.
    When Disk Utility launches, use the "Zero Out Data" option under the Erase tab.  Erase the entire disk, not only the free space.
    One pass of zeros is secure enough for normal use.  One pass will take a couple of hours, so plan some time.

  • Unable to install Lion on new hard drive.

    Hello,
    My brothers laptop hard drive died so I am fixing it for him. I've replaced the hard drive, created a bootable USB Lion install by following http://osxdaily.com/2011/07/08/make-a-bootable-mac-os-x-10-7-lion-installer-from -a-usb-flash-drive/.
    I plug in the USB, hold down option, select the USB drive, and I get the wheel spinning and apple logo. After two or so minutes it turns into:
    Does anyone have any idea as to why I am getting this? I've tried changing which USB hub it uses, tried redoing the USB, used a different USB, verified the md5sum (145dc094527a8d5f5f601c7fa53d7577) all to no avail.

    Most likely you have a non-functioning system. It could be because the flash drive was not partitioned and formatted properly before you created the system on it or a flaw in your cloning. Not knowing which specific model you have it could also be that the system you cloned is not able to boot the computer because the computer requires a different version of Lion.

  • What packages to install, and how to install in an USB hard drive

    Hello.
    Well, as I said in another thread, I want to install in an USB hard drive. But I don't know how, because it hasn't graphical installer, but text installer. I tried in a virtual machine, and it was fine, but when I want to start it, an error appears, "Was not found a bootable system" or something. Maybe a VM is not as a computer, but... well. I didn't change anything while I was installing GRUB, and I know that I've to install it in /dev/sdb.
    And I want to know too, what packages to install and what packages don't (the ones which are neither "base" nor "base-devel"). But I'll install sudo, links and ndiswrapper (for wifi).
    Thanks, and excuse me if my English is bad.

    Gotta use the wiki my friend and this one is even translated into Spanish:
    https://wiki.archlinux.org/index.php/In … C3%B1ol%29
    As to your question about which packages you'll need beyond those in base and base-devel - that depends on what you want on your system... no one can answer that but you!
    Welcome to Arch.

  • How can I securely erase the hard drive for PowerBook G4 running 10.2.3?

    I'm about to sell a PowerBook G4 12-inch running 10.2.3 after I erased the hard drive via the the original software install and restore disk. There was no secure erase option like there is in subsquent versions of OSX. Is there a way I can do a 7 (or 35) time erase on this machine? Thanks!

    See this Apple note. Secure erase was added in 10.2.3, but in a different place than later releases.

  • How to recover data from the hard drive?

    I've always heard that data is never really gone from the hard drive even after you delete it. How do I recover that data? My problem is some photos (my honeymoon photos) have been deleted from my computer and they have also been deleted from the recycle bin. I sure would like to recover them.

    First stop using your system, then get a copy of a program that will recover files like Data Rescue 3.  If you have a time machine backup you may be able to restore them. 

  • Is there a 'how-to' anywhere about upgrading the hard drive?

    Hi Guys,
    I'd quite like to upgrade the hard drive in my 24 inch 3.06GHz iMac to 2TB. Is there a step-by-step 'how to' available anywhere or has anyone done it successfully?
    I've done laptops on many occasions but the iMac has a difficult looking case to crack!
    Thanks
    Rich

    Hi mate,
    Haha, no I have no preconceptions about firewire! My iMac has a 400 and an 800. The 800 is connected to a Sony DV video deck and the 400 is connected to a RAID drive that is then daisy-chained to another external firewire and a Wiebetech bare hard drive device that I just swap out various hard drives to for clients.
    I suppose I should really be looking at a tower, but I sold a G5 Quad to downsize to the smaller footprint iMac and have been happy with it's performance - but the new ones have more space and more RAM capability - it's just a shame they don't have the connectivity options of even this iMac.
    Cheers
    Rich

  • Clean the hard drive before OS upgrade?

    Upgrading from Snow Leopard to Yosemite. I trashed 100gb of old files. I double saved my photos and music and emails. Backed everything up with Time Machine. Wondering at this point if I should just wipe the hard drive and start with a clean machine.
    Thank you, Andy

    That probably isn't really necessary, but this you should do:
    Repair the Hard Drive and Permissions
    Boot from your Snow Leopard Installer disc. After the installer loads select your language and click on the Continue button. When the menu bar appears select Disk Utility from the Utilities menu. After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list.  In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive.  If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the installer.
    If DU reports errors it cannot fix, then you will need Disk Warrior and/or Tech Tool Pro to repair the drive. If you don't have either of them or if neither of them can fix the drive, then you will need to reformat the drive and reinstall OS X.

  • How do I install Lion on external hard drive? I have purchased and downloaded through App Store but do not know where the download is located so I can install.

    I want to install Lion on an external hard drive. The OS was purchased and downloaded through the App Store but I do not know where the file is.

    If you downloaded the installer it will be in your applications folder. Failing that use spotlight start typing Install and it should show up.
    This is assuming you downloaded the installer from the app store, and didn't just install it onto your mac. If all you have done is install it on your mac. Go to your purchases Lion should show up. Then click download.
    Here is the Support page for installing osx on an external drive.

  • How to install Leopard to external hard drive & boot the eMac from it.

    I am attempting to update my mom's eMac so she can use her new iPad and have discovered it would be best to install Leopard onto an external firewire hard drive and boot from that. I want to be sure I'm doing it right. So, I attach the drive to the eMac, partition and format it (I did find some instructions in the forum) and then how do I load Leopard on the external drive. Would it be best to do all the formatting and installation from my own MacBook Pro? After Leopard is on the external drive, how do I cause the eMac to boot from it?
    Or would it be easier to return the iPad, buy the basic Macbook and shine the eMac? Can you tell I'm frustrated?

    how do I load Leopard on the external drive
    Install it normally. The drive must be connected with FireWire.
    Would it be best to do all the formatting and installation from my own MacBook Pro?
    No. It won't work if you do.
    how do I cause the eMac to boot from it?
    Start up with the Option key held down, click on it, and push the button with the straight arrow.

  • I need to recycle my old G3-how do I clean the hard drive on a 9.2 system before recycling it.??

    Any tips on how to get rid of all my data on hard drive before the recyler gets it?
    My system is 9.2 its an old g3 mac.

    I disagree with your choice of a solution.
    1) The answer does not mention removing the platters that contain the data from the drive, so I guess you'll just smash the whole unit. I don't know how recyclers operate in detail but making a mess of the drive will likely make it more difficult (impossible?) for the recycler to isolate the components that are hazardous or valuable.  I could give you a bag of food and you could pick out the canned items, but if I run over the bag with a car a couple of times you would likely just throw the whole lot in the trash.
    2) Removing a drive and taking out the platters would take you just as long as booting it up, erasing it with write zeros in Drive Setup while you do something else.
    3) Some people can actually make use of a non-pulverized old drive.  There are still people around who run G3s and look for compatible drives, especially if they are free.  I know our local waste dropoff place also has a pickup area where you can look for things you can use, including electronics.  The last couple of G3s I wanted gone I just posted on Craigslist and I had several takers (as recently as 6 months ago).
