How can I boot from USB drive?

I have installed a Kingston SSD drive on my Macbook Pro. The original HDD is now in a USB enclosure. I tried to boot from the supplied CD by selecting it in the preferences. However they supplied a CD with Aarons for Windows. Now I cannot either clone my HDD to the SSD or boot from the original HDD. How can I override the CD as boot disk?

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 disk icon of the external USB drive.
  5. Click on the arrow button below the icon.

  • How Can I boot from USB - Portege A200

    Hi,
    I've got an Portege A200 which is only a couple of years old but the hard drive no longer works. Initially I thought this was due to corrupting the boot record on the drive but after attempting to replace the hard drive (with two different drives) it is showing an IDE #0 error upon boot. I have therefore come to the conclusion the IDE controller chip has died.
    In order to get the latop working I burned a cd with the ubunto ISO. This boots ok but due to only have 512Mb RAM the system is somewhat limited and anything installed is lost everytime I reboot.
    I have now bought a 2Gb flash drive and installed ubuntu onto this. My next problem is that there appears to be no boot from USB HDD or USB Memory Stick option in the bios.
    The possible options that I can think of are:
    1) Upgade the bios so it supports boot from memory stick (although no HDD so not sure how I could reflash the BIOS or if there is even a BIOS upgrade that would support this functionality)
    2) Create a cd which starts the boot process then tells the system to continue booting from the usb drive (Is this possible and does anyone know where I might be able to obtain such software)
    3) Boot from CD but use the USB to retain any information saved / any installs etc (I guess similar to option 2 except the cd would manage the whole OS and the USB would just hold 'additional' information)
    If there are any other options that anyone can think of I am happy to give them a go. Seems a shame to have to chuck a laptop that isn't particularly old because the IDE controller chip has failed on the mobo.
    I apppriciate any help anyone can offer.
    Many thanks,
    Mark

    Hi
    First of all I have to say that its not possible to boot from the external USB device like the USB stick, USB CD/DVD drive or USB HDD.
    Its possible only to boot from the external USB FDD (diskette) drive
    However, not the booting possibilities are clear but I think you have misunderstood the IDE#0 error message. In m opinion the IDE controller is not faulty but only the new HDD is not compatible and not recognized by BIOS.
    There are different reasons for this issue
    Mostly this error message appears if the HDD master/slave/c-sel settings are not correct.
    Usually such settings dont need to be changed or switched on 2.5 HDDs but some HDDs support an jumper which must be set in the right position. But I dont if your HDD supports this
    Furthermore the not compatible HDD size could be the reason for such error messages!
    So finally I would recommend contacting the ASP in your country to get a new, compatible HDD and to check if the same error persists.
    Good luck

  • How can I boot from USB 3.0 disc on a Mac Pro 2013

    I am just setting up a 2013 Mac Pro with a 4TB USB 3.0 external drive. I have cloned my boot disc over to it but have problems being able to boot from the USB drive.
    It shows up in the startup disc in system preferences, but when selected as the boot disc and restarted it just boots from the internal SSD. Also have checked booting and holding the ALT key to see what happens but I am just shown the SSD and Recovery disc as options to boot from.
    So it appears I can not boot from a USB disc on my new Mac Pro, is there a solution to this problem?

  • How can I boot from Clone Drive?

    I believe that I am having some problems with my boot drive, and I would like to boot up my system using the boot drive I created with Carbon Copy Cloner, which is on another internal HDD within my tower.  I would like to boot with that cloned copy, but have forgotten how to do it.  My boot drive is a SSD drive, and appears to be working well, but disk permissions showed many errors, most of which I was able to repair with repair disk permissions, but not all of them.  Any help and/or direction is greatly appreciated.

    System Preferences > Startup Disk ...
    ... will show all Volumes it thinks it can boot from. Set to whichever one you want.
    That presumes your Mac is booted up and System preferences is working.
    If not, hold down the Option key at Startup.
    You get a display of all bootable Volumes, and the Eject key is "live" once they are all drawn.

  • Downgrading from Mavericks to Snow Leopard, can't boot from USB drive

    I'm attempting to do a clean install of Snow Leopard on a 2010 Macbook. The MB had recently been upgraded to Mavericks, but because it was running slowly, I decided to downgrade. (If you respond to this post, please don't ask me why I'd make this decision.)
    As with any other clean install I've done--all pre-Mountain Lion--I backed everything up, I created a .dmg file of the Snow Leopard, and made a perfectly good, bootable USB drive with the OS (1 partition, GUID table); I tested this USB drive on another Macbook, one currently running Snow Leopard, by holding option as I booted up. It works fine and gets to the installation screen.
    I booted the Mavericks Macbook while holding command+r, and I erased the main HD. I then formatted it with 1 partition, with a GUID table. All was normal.
    But here's where the problem starts. I plugged the USB drive into the formerly Mavericks computer, and held option for the bootloader. It recognizes the OS. But when I click the arrow to proceed, it inevitably has a kernel panic and tells me to restart the computer.
    I re-made my bootable drive, and I tested it again on the other machine. Again, it's still fine. Plugged it into my main machine--again, a panic.
    Using command+r to reach disk utility, I've now erased and repartitioned the computer's hard drive several times, even using the advanced-security erase feature. Still, the panic.
    When I hold command+r at boot, it always forces me through the Internet Recovery. The only option offered to reinstall OS X is with Lion, which I didn't buy with my Apple ID.
    What can I do?

    Sorry, but this didn't help me. From what I gather, Mavericks (or maybe Mountain Lion) included a firmware update that, for some reason, prevents users from downgrading to anything before Lion. This makes things difficult, because I didn't buy Lion--I made the leap from SL to Mavericks.
    Here's the strange part, I learned: When I enter Internet Recovery, I'm prompted to reinstall Lion, not Mavericks. And because I didn't buy Lion, my Apple ID/password, which are asked for, don't help.
    Anyone else with suggestions? None of my USB-based installations are working, and I'm feeling out of luck. I don't want to spend money at the Apple store...

    Hello
    Why Tecra M2 don't have boot from USB drive in BIOS?
    Is posible implemented this function in new BIOS.

    Good question. You should ask this the Toshiba engineers.

  • MacPro can't boot from external drive

    Running 10.7.3 and a MacPro which gets backed up each night with SuperDuper. Can't boot from this drive (black screen). Yet I can take the same drive and start up my Macbook Pro! So it isn't the drive or the data on it. I'm stumped. Could this be related to an issue where I can't get this same MacPro or system to successfully backup to Time Machine without error? The boot drive seems OK (ran Disk Warrior and Disk Utility).

    Please read this whole message before doing anything.
    This procedure is a diagnostic test. It’s unlikely to solve your problem. Don’t be disappointed when you find that nothing has changed after you complete it.
    The purpose of this exercise is to determine whether the problem is caused by third-party system modifications that load automatically at startup or login. Disconnect all wired peripherals except those needed for the test, and remove all aftermarket expansion cards. Boot in safe mode and log in to the account with the problem. The instructions provided by Apple are as follows:
    Be sure your Mac is shut down.
    Press the power button.
    Immediately after you hear the startup tone, hold the Shift key. The Shift key should be held as soon as possible after the startup tone, but not before the tone.
    Release the Shift key when you see the gray Apple icon and the progress indicator (looks like a spinning gear).
    Safe mode is much slower to boot and run than normal, and some things won’t work at all, including wireless networking on certain Macs.
    The login screen appears even if you usually log in automatically. You must know your login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin.
    Test while in safe mode. Same problem(s)?
    After testing, reboot as usual (i.e., not in safe mode.)

  • How to dual boot from usb thumb drive in lenovo x1 carbon

    How can I boot Lenovo x1 carbon 2014 from an USB thumb drive? It has Windows 8.1. And I have tried disabling secure boot in bios setting. And set usb drive to boot order 1. But that still does not work.

    I use the 
    Windows USB/DVD Download Tool too to create the usb thumb drive. And I use the tool to copy the iso file there.
    And when I use that drive on an older laptop runs windows 7. it works.

  • How can I boot to USB device if no USB boot option in BIOS

    I just purchased a Toshiba NB305-N410BL but am concerned as to how I would image the 250GB HDD if I can not boot from an external cdrom drive.  I tried to backup to shared network folder but none show up on list.  Only boot options in BIOS are HDD, FDD, and LAN.  Thanks for all help in advance.

    Hi, buddy-erp.
    I don't know if my instructions apply to you because I only have the NB305 model. However, if you say you have followed all instructions, that is, 1) insured that no other USB devices are connected to your computer at bootup time and 2) have pressed F12 to enter the boot menu; 3) and then designated the USB flash drive as the source of the bootable restoration software you may need Toshiba technical support. I wonder if there is a BIOS update for your computer too. This may need to be downloaded and installed prior to beginning the restoration process. Nevertheless, as stated, I have a NB305 model and the instructions are clear. FYI (for your information), a virus infected my system and made certain changes to this process. Toshiba technical support informed me that the information displayed was wrong and the process outlined was unnecessary but did require technical support to restore it to the OEM default options.
    Good luck.
    Sincerely,
    Bi-Ill
    Good luck!
    Sincerely,

  • How can I boot from my recovery dvd to reach the system recovery C: on a extern hard disc

    I think a have a virus in my notebook Pavilion 15 and want to restore my C partition with a system back up. I made this system back up a month ago and it is stored on a extern hard disc. I have also made a recovery dvd. How can I boot my notebook from my dvd to start the procedure? I have 2 partions on my notebook. The second partition contains My Documents.
    Thanks in advance.

    It is unlikely that the back-up of the system recovery, that you have stored on an external drive, will be useful in recovering your computer. Please see HP PCs - Performing an HP System Recovery (Windows 8), for instructions on using the HP Recovery Disc set your created earlier. Typically, the disc set is 4 to 6 DVDs.
    If you have any further questions, please don't hesitate to ask.

  • Imac 21" mid 2011 can not boot from USB device?

    Hi,
    hope someone can help me.
    Bought the new imac 21" and replaced the superdrive with a ssd drive.
    Works great but it seems that the imac is not able to boot from any usb device.
    I put my osx install disk in my external dvd drive and powered my mac.
    While booting up (pressing cmd) the mac does not recognize my external dvd drive. This works great with my MBP late 2008. But the imac can not boot from the dvd drive. Also pressing "c" while booting does not work. Doing that a grey screen appears and after some time mac boots from hdd.
    So i installed mac os via target mode over firewire withbmy old imac. This works.
    But now i want to install windows on a bootcamp partition.
    I can't boot from the windows 7 professional dvd, too. So i tried to create a bootable win 7 thumbdrive. Mac can't boot from this too. Reading many threads in some forum i tried with rEEfit. Reefit shows the usb thumbdrive whike booting, but using this will end in a black screen error from bios: "no bootable device....". Tried a knoppix on the usb thukbdrive, too.... No bootable device....
    It seems that there is no way to boot from ANY external usb device like dvd drives or thumbdrives......
    What more can i do? I tried for 2 evenings now, but nothing worked out for me......
    Currently i don't see any any to install win 7 without an internal superdrive, but can this be??
    Thanks for any comments.
    Kwicks

    Internal is definitely the easiest but you can boot from external HD or external optical drive, the mac is just very picky on what works and what doesn't.
    For an external drive or usb stick it has to be GUID partition table and have 10.4.5 or better installed on it, for more info check this link out ( http://support.apple.com/kb/ht1948 )
    Hope this helps,

  • Cannot boot from USB drive!!!!!!!!!!!!!

    Hi
    I have 3-4 120Gb 2.5inch drives which I clone my MacBook Pro to on rotation.
    I have always been able to boot from these drives UNTIL NOW!
    Suddenly I can no longer boot from them, the boot process starts and gets well through and then the drives all seem to just 'hang'.
    The only significant change is that a local Apple support company upgraded my stock 120gb drive to a 160Gb drive.
    Any ideas what the issue coiuld be?
    Cheers.
    Robin

    Hi robster,
    If the USB drive contains a valid OS you should be able to verify and repair the permissions on that drive, give that a try.
    Also i suggest running DiskWarrior 4 on it.
    The replaced internal drive should have no effect on this unless some settings got changed when the new OS got installed on it that now prevents the mac from being able to read your USB drive.
    Does the USB drive need a driver ? if so is the latest version of that driver properly installed ?
    If the USB drive checks out and all is OK maybe a re-install of the OS on your internal drive would help.
    For now try disk utility and diskwarrior if you can that could narrow things down

  • Won't boot from USB Drive

    I am trying to replace my internal drive. I got a WD Scorpio from OWC and formatted and installed OS 10.6. But when I boot from the drive I get the panic screen.
    The drive otherwise behaves normally. I can see the files, etc.
    Also, strangely, the drive is only recognizable as bootable from the right USB port. That doesn't really make any sense to me.
    Please help! The OWC folks have sent me multiple drives and have really tried to get this working, but I have the same result each time. Anyone out there have a solution?
    Thanks.

    Try prepping the drive this way:
    Drive Preparation
    1. Boot from your OS X 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.
    2. After DU loads select your hard drive (this is the entry with the mfgr.'s ID and size) from the left side list. Note the SMART status of the drive in DU's status area. If it does not say "Verified" then the drive is failing or has failed and will need replacing. SMART info will not be reported on external drives. Otherwise, click on the Partition tab in the DU main window.
    3. 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 (for Intel Macs) or APM (for PPC Macs) then click on the OK button. Click on the Partition button and wait until the process has completed.
    4. 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.
    5. 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.
    6. Click on the Erase button. The format process can take up to several hours depending upon the drive size.

  • Booting from USB drive on PPC

    Hello everyone!
    I know I will have people agree with me or possibly disagree with me, but if you goto the following site and see my pictures of my 2003 G4 MDD booting up Leopard from an external USB drive, you will see that this is fully supported. Also, what is strange is that although I found the tip through macfixit.com and other sites, one really doesn't have to go into the firmware and do anything.
    As the pictures show, my USB 2.0 drive booted right into Leopard in less than 20 secs.. Please visit
    http://s704.photobucket.com/albums/ww50/psychomacuser/ and see for yourself USB 2.0 in action on my system. Sorry if you have trouble reading the cyrillic, I have my system set up in Russian.

    Hey Nadav, thanks for the post.
    What tip did you find exactly? Just that you can boot from USB?

    Hi:
    I would make a set of recovery disks first before proceeding.
    To boot the PC you need to go into the BIOS and enable legacy mode.
    Then you should be able to boot from another device.
