How to create boot disk

Tho' my MBP is working fine (I think) Disk Utility tells me my HDD is corrupted and needs repairing.
Disk Utility tells me "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."
How can I do this, having simply downloaded Lion?

I strongly recommend to use Disk Warrior.
If you don't have it already, I believe you should purchase it.
If you are interested, you can look it up at www.alsoft.com.
I am not an Alsoft shareholder :-). I have been using Disk Warrior since it was released, too many years to tell exactly.
Now more specifially about your pertinent question, there's no "installation disc" for Lion, we all downloaded it from App Store.
If you don't have it already, you might want to consider backing up your entire computer to an external (preferrably portable) back up drive, that is really not expensive. That external back up drive should be bootable, to enable you to boot from it (when it is connected to your computer via USB or any other suitable port that your computer supports.
That's what I have been doing for years, and am still doing now.

  • How to create 800K disks for Mac Plus

    I've acquired a Mac Plus in good working condition, but it's just standalone. Eventually I want to network it, but for right now, is there a way to use my Mac Mini or a PC to create 800k disks for the Mac Plus? Things like OS upgrades and other software are available out on the net, but I can't get them to the Plus. I've tried a USB floppy disk drive on the Mini, but it only works with HD diskettes.

    sacsr,
    "Can I take MacPlus-appropriate software from the internet, burn it on a CD on my Mac Mini, and load it into the Mac Plus?
    Yes! : ) That simple. The Plus was the first 'business Mac' and I loved it until I got a dual floppy SE with an external SCSI HD and an excellerator card with a math co-processor. It was a very capable computer. But, as soon as you used a faster Mac, you never went back to the Plus. You could fix lunch while waiting for disk swapping to boot and load MS Word 3.
    What we are saying is that the SCSI bus on the Mac Plus has far more options available for someone shopping for resources.
    We have over 300 Macs of almost every model. We have been given over 100 floppy drives. We shop at government surplus stores and auctions. In all that stuff, we only have a couple of 800 k drives but hundreds of SCSI devices. They are SO much easier to find and are so much cheaper to buy and customize.
    If you can find a Macintosh 800K (M131) floppy drive, great. Then you also have the problem of finding double density floppy disks ( high density disks with tape over the hole are not reliable in the older drives.)
    here is a website with the whole list:
    http://www.mandrake.demon.co.uk/Apple/drives.html
    I remember buying an 800k floppy drive new in 1986 for several hundred Dollars. The external CD-ROM drives sold for $300.
    It will probably be much easier to find an Apple 300 or 600i CD-ROM drive that should read CDs burned in your modern Mac. Your original question was about floppies. The real question is "How do I get data from a new computer to an old computer." That question offers more possibilities. I am suggesting a better and cheaper alternative. Having fun with older equipment requires purchasing intermediate equipment.

  • How to make boot disk for MacBook Pro with Mavericks pre-installed

    Hi -
    I recently bought a new 15" MacBook Pro with Retina Display, which came pre-installed with Mavericks (10.9.0).  I want to make a bootable USB disk of the system software, and have successfly used DiskMaker X (formerly Lion DiskMaker) to make the USB boot disks for Lion and Mountain Lion.  In those cases, however, I was running earlier versions of the OSX, and downloaded the new OSX version -- Lion and Mountain Lion -- from the App Store in order to make to make the disk.  In this case, however, Mavericks was pre-installed, and I was unable to download it from the App Store (an alert said that it couldn't be installed on this computer... presumably because it was already installed).  I would apprecite any suggestions as to how I can create the boot disk without the ability to download Mavericks.  Thanks very much for any help anyone can provide.
    Shelly

    Open App Store and locate the full installer download file (5.29 GBs) for 10.9.1. Download to your computer.
    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.
        3. Use DiskMaker X to put your installer clone onto the USB flash drive.
    Make your own Mavericks flash drive installer using the Mavericks tool:
    You can also create a Mavericks flash drive installer via the Terminal. Mavericks has its own built-in installer maker you use via the Terminal:
    You will need a freshly partitioned and formatted USB flash drive with at least 8GBs. Leave the name of the flash drive at the system default, "Untitled." Do not change this name. Open the Terminal in the Utilities folder. Copy this command line after the prompt in the Terminal's window:
    sudo /Applications/Install\ OS\ X\ Mavericks.app/Contents/Resources/createinstallmedia --volume /Volumes/Untitled --applicationpath /Applications/Install\ OS\ X\ Mavericks.app --nointeraction
    Press RETURN. Enter your admin password when prompted. It will not be echoed to the screen so be careful to enter it correctly. Press RETURN, again.
    Wait for the process to complete which will take quite some time.

  • How do change boot disk from single user mode?

    My G5 hangs when booting at the blue screen while "Loading printing services...". Attempting to boot into safe mode only hangs at the grey gear screen. It will, however, successfully boot into single user mode. I've run fsck but no change in bootability. I have another disk in the machine that has Tiger on it. How do I change the boot disk from the single user prompt?

    You can hold c and boot off the installer disk and select disk utility repair disk/permissions
    or you can hold option to boot off Mac OS X on another drive, like a clone and run Data Rescue to recvoer your files.
    It does sound bad, you can try going through these
    http://docs.info.apple.com/article.html?artnum=106464
    But I think you'll need a fresh install, hopefully you have been backing up/cloning to a external drive.

    That will include the Lenovo recovery image - or it's supposed to anyway.  I can't test since I only have a 7 -> 8 updated machine at the moment.  This only works correctly when used on a machine containing the original Lenovo Win 8 install.
    256MB gets you the Win 8 recovery/repair tools but not the image.  When the image is included it will take multiple GB.  I'm told an 8G flash drive is required.

  • Create boot disk?

    Hi,
    I am away from home, and I need to create a boot disk, and I do not have my system install DVD. Anybody know of a solution to create a boot disk, either on a removable media or an external HD? It seems like I should be able to create a partition or a disk image on my firewire drive and copy key system files to it and start from there, run my utility programs. Restart and life is good again.
    Any thoughts?

    Clone your internal drive to the external using CarbonCopyCloner or SuperDuper!, then boot from the clone to run the utilities.

  • How to create recovery disks for Lenovo H530s with WIndows 8.1

    Hello there,
    I just purchased a Lenovo Hf30s type 10131 with Windows 8.1, mini tower: http://support.lenovo.com/us/en/products/desktops-and-all-in-ones/lenovo-h-series-desktops/lenovo-h5...
    I like to create recovery disks, but  the already installed program OneKey Recovery does not have the option of recovery disks, it allows only larger media such as USB stick and hard disks.
    Here to I have 2 questions:
    1. Is there a way to create a recovery disks that will create the original factory settings with 5 partitions?
    2. Does any one knows if the recovery siskd sold by Lenovo (for Netherlands they cost between 23 and 38 Euro) would do the job by creating the factory settings with 5 partitions?
    My goal is to reformat the hard disk and aprtitionig it the way I need it, but in case of anything, I would like to be able to go back to the original facttory state of the unit, especially if I have a harddisk failure and neer to replace the hard didks.
    Thank you in advance and I wish you a very pleasant and successful day.

  • How to create recovery disk on HP envy dv6 7258nr notebook pc - window 8

    I m trying to create recovery disk from recovery drive which is created by hp while purchasing the laptop, while taking back up from recovery manager, Recovery Manager says   (Recovery Partition has been removed - Recovery Media creation option is no longer available) , but as per my knowledge i did not took back up of recovery drive. So what should i do to take back up of my recovery drive to **bleep**.

    Based on what you have stated, it appears that you or someone else with access to your notebook deleted the recovery partition. Without the recovery partition on the hard disk you can't make recovery media.
    Your best option at this point would be to purchase a recovery disk set from HP or an HP Partner.

  • How to create recovery disk for windows 8.1 after update from windows 8.

    My laptop came with windows 8 and i have recovery discs for windows 8.
    Now i've updated to windows 8.1, so i want to creat recovery discs for windows 8.1.
     So in future when i use recovery discs i dont have to download windows 8.1 again.
    Please tell me if there is any way to do this.....

    As colakid posted, in Windows 8 the ability to create a recovery CD/DVD has gone. Your options are to:
    create a recovery USB; or
    create a recovery image.
    Recovery USB
    Colakid's post talks you through how to make a recovery USB: from control panel, choose Recovery, then Create a Recovery Drive, and follow the prompts.
    However, the 'recovery USB' can be a bit misleading. When the wizard starts, there is an option to 'copy the recovery partition from the PC to the recovery drive'. If you do not check this option, you will still need installation media to reset your PC.
    Since you have upgraded from Windows 8 to Windows 8.1, you will probably not be able to check this option, as it will be greyed out (like it is in the picture in Colakid's post).
    If you go ahead and create the USB anyway, you will be able to boot to it, but you won't be able to reinstall Windows unless you have the installation media (or possibly a system image, though I haven't tried that).
    Recovery image
    The recovery image is an image of your computer that Windows will use when you select the 'refresh my pc' option. You can create a recovery image using the recimg.exe tool.
    First, open an elevated command prompt (type cmd and press Ctrl + Shift + Enter).
    Next, create the recovery image by typing:
    recimg /createimage [path]
    Where [path] is the folder you want the image in, eg C:\Recovery. You cannot set the file name - it will always be called CustomRefresh.wim.
    Let it run its course. When it's done, you can check that it is the current recovery image by typing
    recimg /showcurrent
    It's important to keep in mind what a recovery image contains. It will have your Windows system files (in their current state), and the desktop apps you have installed (so it makes sense to do this after a fresh install of Windows). It will
    not backup any Metro apps or user files, because these are not deleted during a system refresh. If you want a complete backup of everything on your computer the way it is now, you should make take a complete system image (which
    can be done from the File History settings in control panel - at the bottom left there will be a 'System Backup Image' option - or you can do it using any other backup software like Ghost or Acronis).
    In my case, I created the recover image straight after upgrading to Windows and it was about 6 GB.
    Prepare/Create and register an recovery partition, so the option Copy the Recovery Partition becomes available in the recovery drive UI  application.
    In elevated command run> RECIMG -CREATEIMAGE C:\REFRESHIMAGE< 
    This will create a new custom.wim in a folder Refreshimage.
    Now lets get ready to register the path of the image, so our create recovery drive option(COPY THE RECOVERY PARTITION FROM THE PC TO THE RECOVERY DRIVE) becomes available.
    >  In the folder you created there will be a> custom.wim<
    change it to>INSTALL.wim<
    > Create a folder In Cd/directory using Elevated command> mkdir c:\Win8.1-Recovery,>
    Win81-Recovery<.
    > Copy the  INSTALL.WIM. Put in the Win81-recovery folder created.
    > Run in elevated commad>REAGENTC /SetOSImage /Path C:\Win81-Recovery\INSTALL.WIM /Index 1<
    Do not copy the arrows if using copy and paste, that is my way of pointing out lines of code
    Information provided by the link below, thanks Keith. I simplified the process for easy following and added my own tweak from trial and error for the install.

  • Qosmio G40: How to create master disk for Windows Vista?

    Hello all,
    I am looking forward to install Windows XP additional to Windows Vista on my QOSMIO G40 (dual boot).
    Before starting this journey I need to secure a little bit the way-back by creating a *master disk* I can boot from to load Vista.
    I am not talking about re-installing Vista starting the re-installation disk but about a master disk.
    Somebody to help me on the subject?

    I am not sure what you mean when you say "Master Disk". Do you mean a floppy disk that has Vista's boot loading files?
    EasyBCD can help you setup the dual boot configuration.

  • How to create encrypted disk image?

    In Disk Utility, I select to create a new image that is password protected. I'm prompted to save and give the image a password. It never ask for the size and starts "Reading whole disk". I don't want to encrypt my entire disk. This image might only be 5MB.
    What steps do I take to create a DMG that is about 5MB and password protected?

    Rename it in the Finder as you would any other item. If needed, choose Get Info from the File menu when the mounted image is selected in the sidebar.

  • How to create a disk image for flash drive backup

    I tried to follow the instructions here – http://www.apple.com/uk/pro/tips/lockyourdata.html – without success. How do I encrypt the contents of my memory stick?

    There is another way to do this if you are a bit adventurous: the terminal. I don't have a lot of experience using the terminal for this, but I just tried it, and it worked, and very quickly (a few seconds to create a 5 gig sparse image). The "terminal" is in utilities, and gives you access to the UNIX underpinnings of os x. OS X is essentially a GUI for UNIX. If you decide to try this, be very careful, and enter the commands exactly as written.
    1. make sure you have a backup of your folder that you want to encrypt.
    2. a backup of your whole system wouldn't be a bad idea either
    3. open terminal (applications> utilities)
    4. select the following line:
    hdiutil create -encryption -size 5g -type SPARSE -fs HFS+ -volname Image ~/Desktop/image
    6. Do not select any spaces before the first "h" or after the last "e".
    6.5 do command-C to copy what you just selected.
    7. go back to terminal. You should see something like this:
    arthurs-mac-mini:~ arthur$ (and then a little grey square)
    8. In my case, the "arthurs-mac-mini" is the name of my computer, and the "arthur$" is the user account currently logged in. the grey square is like the cursor.
    9. paste the line you copied and hit return
    10. it should prompt you twice to enter a password. enter it and hit return after each.
    11. your new sparse image should appear on your desktop. If you like you can change the name of it from "image" to something else.
    12. you can then open the image and copy your folder contents to it. The image should resize itself automatically to whatever you put in it.
    13. hope this helps. let me know how it turns out.
