  • How to create a Lion Boot Disc?

    Hi there,
    When Lion was release I updated from the App Store.
    I recently had to Repair my HDD using Disc Utilities and DU wanted me to boot from an install disc . . . guess what . . . no install disc.
    (Well I do have my Leopard install disc)
    How does one create an install disc for Lion if it was instaled via the App Store?
    Thanks!
    Matthew

    One can make a "hold the option or c key bootable" Lion boot DVD with a factory Lion Mac (or a Mac with Lion already installed) following these combined directions.
    One will need a blank external GUID OS X Extended journaled (aka: "JHFS+") formatted drive and standard 4.7GB DVD(s)
    Step 1:
    It's very easy to use the Mac App Store's smarts to our own advantage and gain access to a copy of that hardware specific OS build. Here's what to do:
    Boot the hardware you need an image for from the Recovery HD by holding Command-r at power on time.
    Plug in a JHFS+ formatted external disk.
    Select the Re-install OS X Lion option and target the external disk.
    Once the Installer finishes downloading, simply shutdown and unplug the disk.
    Now when you mount that external disk you will find a directory named Mac OS X Install Data on the root. Inside of this folder is the elusive, hardware-specific, InstallerESD.dmg image that you can feed to SIU or any other imaging tool of choice. Having this installer will now allow you to build out re-deployment images for all of your hardware until rollup installers are available.
    http://www.afp548.com/article.php?story=getting-lion-installers
    Step 2:
    Inside the Contents folder that appears you will find a SharedSupport folder and inside the SharedSupport folder you will find the “InstallESD.dmg.” This is the Lion boot disc image we have all been waiting for.
    Copy “InstallESD.dmg” to another folder like the Desktop.
    Launch Disk Utility and click the burn button.
    Select the copied “InstallESD.dmg” as the image to burn, insert a standard sized 4.7 GB DVD, and wait for your new Lion Boot Disc to come out toasty hot.

  • Need to run Disc Utility - But dont have Boot disc to hand

    Hi,
    I have run Disc Utility in OSX on my main hard drive and it says it needs repairing, so I need to boot of one of the install disc's, unfortunately I don't have these to hand at the moment (there at home & I'm not)
    There must be a way round this e.g. creating a boot disc with Disc Utility on it etc.
    Any idea's?
    Thanks

    Check out this info from Apple. Pay particular attention to Safe Boot and fsck. These operations perform steps that are somewhat like running disk repair while booted from your install disc.

  • Burning a Third-Party Boot Disc

    Hi,
    I'm trying to create a boot disc on my MacBook Pro for another computer. The OS I am going to be burning on there is a third-party OS, NOT Mac. ( http://centos.org/ ) All I am finding is information on how to backup my Mac OS boot disc. I'm on Leopard 10.5.5. Any help?
    Cheers,
    B

    Hi,
    although I am having difficulties understanding what you really want to burn/backup, I try answering:
    To backup the OSX volume on your internal harddisk you can use Time Machine which is part of OSX Leopard or SuperDuper or Carbon Copy Cloner and an external harddisk.
    http://www.apple.com/support/leopard/timemachine/
    http://www.shirt-pocket.com/SuperDuper/SuperDuperDescription.html
    http://www.bombich.com/software/ccc.html
    For burning CDs/DVDs you can use Disk Utility (see the help files in Disk Utility for how-to) or SimplyBurns which I prefer.
    http://simplyburns.berlios.de/
    For making a copy of your OSX Installation DVD you must use a DVD-DL+R since the OSX DVD is larger than the 4.7GB of a standard DVD-R.
    Depending on the size of the CentOS you can use a writeable CD/DVD/DVD-DL.
    SImplyBurns has an interface with five buttons from which you choose '1:1-Disccopy' to make the copy.
    Hope it helps

  • Do I need Vista boot discs for a new hard disc if I am installing 7?

    I am trying to install a new hard disc on an old laptop.  The laptop is an Hp pavillion dv 6700 with vista.  I want to install an WD SATA hard disc (the original is going bad).  I do not have the Vista boot discs but I do have a new Windows 7 Ultimate disc.  I tried to install and all it says is "operating system not found".  Do I need the vista boot discs? Do I need to update the bios?  I just don't understand why it will not work.  I am a novice in computers but really don't want to keep pouring money in an old laptop by taking it to a pro and spending a couple hundred bucks just to do this.  I have already spent enough...Any help would be greatly appreciated!

    Sorry about the oversight.
    It shouldn't matter what bootable disk you throw at it, it should boot.
    Doesn't sound like anything will work since you have tried all avenues.
    The problem your notebook seems to be having is the only device it will boot from is the hard drive, and since nothing is on it, you get the error.
    The only other thing I can think of is to do a hard reset of the notebook.
    http://h20000.www2.hp.com/bizsupport/TechSupport/Document.jsp?lang=en&cc=us&taskId=110&prodSeriesId=...
    There is only a windows-based flash file so you can't do a BIOS update with no OS installed, and you can only flash the BIOS in Vista or you will brick the notebook.

  • MacBook Pro frozen at bank screen with boot disc in SuperDrive

    I noticed my notebook running a little slower than usual so I took the usual steps, without much luck.  I then verified and repaired disk permissions in Disk Utility.  Tried to use disk repair but got a message that the disk was damaged and I needed to boot from an install disc and run Disk Utility from it.  I put the disc in, chose it as my boot disc in Preferences,  and ever since once I power up all I get is the chime and a blank grey dead screen.  Can somebody either help me proceed or at the very least remove the disc from the SuperDrive   Thanks in advance

    OK got the disc to eject, Thank you.  computer is functioning again but I'm back to square one with Disk Utility giving me the following message:
    Verifying volume “Macintosh HD”
    Checking file systemPerforming live verification.
    Checking Journaled HFS Plus volume.
    Checking extents overflow file.
    Checking catalog file.
    Invalid sibling link
    The volume Macintosh HD was found corrupt and needs to be repaired.
    Error: This disk needs to be repaired. Start up your computer with another disk (such as your Mac OS X installation disc), and then use Disk Utility to repair this disk.
    What is my next step?  I don't have an installation disc, I upgraded to Lion online.  Is there any other way to proceed?

  • Get "no bootable device- insert boot disc and hit any key" error

    Hp G72 Laptop, Windows 7 64 bit,
    "no bootable device-insert boot disc and hit any key" (I have no boot disc.)
    I was in the process of replacing the hard drive and the computer was starting the final phase after copying all files. When it restarted the first time, I got the message. I was getting this message randomly prior to replacing the hard drive and if I turned it off for 2 or 3 hours and turned back on I would not get the message. The reason for replacing the hard drive was a "Smart Disc " imminent failure error message.

    Yes and yes. The final recovery disc had completed and it was moving to the next phase. It said the computer would restart several times during this phase and when it went to the first restart, the error message came up and I could proceed no further. I ctrl/alt/del and restarted, pressed escape to get the start-up menu but was lost at all the options. The information screen looked like the old hard drive info.

  • How do I transfer my boot disc data to a new disc and have the new disc become the boot disc?

    My original 500 Gb boot drive is full (~800 Mb available).  I purchased a 1 Tb drive and installed it (no problems).  Now I want to transfer everything on my original boot disc to the new drive and have the new drive become the boot disc.  I would then wipe the original disc and use it for data backup.
    Can I simply copy all the contents of the original disc to the new disc (this seems too easy...)?  I am in that process, now, but am feeling insecure about it.  I do have Time Capsule.  However, when I went into it to restore to the new disc it wouldn't perform the task - maybe I am overlooking something...
    Suggestions are welcome!
    Thanks
    Jim

    No, the system won't 'copy' but you can clone it.

    http://macperformanceguide.com/Mac-HowToClone.html
    http://www.bombich.com/software/ccc.html
    You could also copy or clone  /Users to the new drive and leave the system where it is and free up most of the file space being used. OS X only needs 100GB. That way all the data is on the new drive.
    And I think you want to add CCC along with TimeMachine to your backup strategy.

  • Corrupt Boot disc - how do I boot from OSX disc to run Repair Disc?

    I have just run Verify Disc and it has identified problems which requires me to boot from my OSX disc and run Repair disc.
    I think I do this by switching on while holding down C....is that right?
    ALSO I can only find my Leopard boot discs and I am currently running Snow Leopard....do I NEED to use the Snow Leopard discs to boot up?
    Thanks in advanced....worried!

    Unfortunate that your HD and Time Capsule are playing up at the same time, to say the least.
    Hopefully your data will be salvageable, and there are several software options to try, here's a couple:
    free (I think) http://www.macupdate.com/app/mac/35373/disk-drill
    and paid for http://download.cnet.com/Data-Rescue/3000-2094_4-211375.html
    I've not used either, but the paid for app may look pricey but it seems highly recommended byt those that have used it.
    Have you tried re-booting the Time Capsule - still seems hard to believe that's gone down as well. Good luck.

  • TS2570 Boot or Restore, can't see my Mac partition but can see my Windows7 partition. From Windows I can access my Mac files which I've backed up on a NTFS drive. I most probably will need to erase the Mac partition & make a new one, what happens to Boot

    Hi,
    When I boot my 2010 MacBook Pro I get a gray screen, when I try to do a Restore, the Mac partition is nowhere in sight, it sees my Windows Partition.
    When I in Windows I can see all the files in the Mac Partition and I've backed up my Mac files on a NTFS external drive. My Windows partition has been working fine, I've installed it 2 years ago and have been receiving regular updates. Only problem is my display driver crashes occasionally.
    I most probably will have to recreate the Mac partition and re-install Mountain Lion from the Mac servers. BUT, what happens to Boot Camp and my Windows 7 partition?
    Any ideas?
    Thanks

    Unfortunately, there is no way to expand the partition upwards. As you noted, you would need to either start afresh, or simply find a good use for the first partition.

  • What is the 3rd Disc in Photoshop Elements.  What does it do?

    Hi All.....
    I am a neophyte.  Just got the new Elements 10, and am in awe about all it can do.  Have been running the tutorials.   I have 3 discs in my packet.  The first disc which I installed is the Photoshop Elements program.   The second disc which I did not install is a trial of the the Premier version...for movies.   The third disc is the focus of my question.   I have put it into the computer and the dialogue box that opens asks for photo places on the computer.  I have called CS but they tell me the 3rd disc is supposed to be templates for printing.   I have opened the files on the 3rd disc but only see the formulary for the things the program needs in terms of space and speed from the computer to function. 
    Question:  What is the 3rd disc for and how do I use it?
    Many thanks....

    So I installed the 3rd disc (have a mac)...I have disc two in the computer and it does not prompt me to install, it sounded like it installed something though?  I do not see an eject to remove it... 
    I am gathering from the previous answer, one only needs to install disc 3 for Elements10  Mac usage?
