My iMac can boot from an external drive?

Hello

I have an iMac 21.5 "Mid 2010 which starts to show its age with slowness. However, I plan to upgrade the Basic 4 GB of Ram either 8 GB or 16 GB of Ram, depending on price... and my main question.  I know that the Mac came initially with a 500 GB hard drive and I would also like to upgrade to an SSD because they make a world of difference from what I've heard, but I don't have the level of skill tech to do the steps together 20-30. I wonder, as I have a 1 TB USB SSD externally, if I could install a new version of Mac OS X on the SSD USB and then set it as my boot drive and just keep still plugged. Would this work or startup disk must be internal rather than external via USB?

Your iMac can be set to boot from an external drive. Just install OS X on the SSD and SSD drive as your boot disk in System-> startup disk Preferences.

  • Vista boot from the external drive

    Dear Sir.

    I recently installed a new hard drive in my Lenovo x 300 laptop and I'm now running Windows 7.  The original hd with Vista, I moved into a box external usb drive, but which fails to start (blue screen after display of the famous Green startup progress bar).

    I think that Vista is lack drivers for my usb drive.  Is it possible to make this work?

    Thank you

    Joeri

    You can not boot Vista from a USB key.  You can leave a disk external eSATA connected to a SATA port, if you have a.

    If you do not have a SATA port or do not want to buy an external SATA drive enclosure, you can virtualize Vista system and the VHD can reside on any drive.  You can use VMWare for virtualization.  See their website for details and the software.

  • Boot from the external drive via eSATA

    Hi all
    I have an external drive which I'm currently starting as a USB device.  The outside also has an eSATA port that I want to be able to boot from. However, when I go into the bios boot area to choose the boot order, there is no option to start using eSATA, USB only.  The Port of the computer's eSATA/USB port.
    This is so my question, how can I get the bios boot option to be able to select an eSATA?
    Thanks for the help

    From what I can find, HP didn't include the option to boot from the port eSATA on this computer.

    Many others have asked about this on the HP forum.

    I would check with HP support, however, since it is the BIOS that must support this function.

    Windows cannot change it.

    See this thread.

  • Of failure, white screen MacBook Pro HARD drive try to boot from the external HARD drive

    Hello

    I have a 2008 Macbook Pro which is having some problems, I was able to fix them, but eventually the hard drive failed. I know that because at startup until it would have a white screen Uni (no logo) and you can hear a clicking on in the lower left corner. I thought initially it was a memory problem, but after opening and verification of memory, it's clearly the hard drive.

    I solved this problem temporarily (until I can replace the HARD disk) by installing El captain on an external HARD disc and start from that. Here's the twist, I couldn't he can begin to El captain, I tried CMD + R, CMD + OPT + R, CMD + OPT + R + P and now shift. Everything that's happened would be that clicks would cease to release the keys.

    I left the macbook on while I'm at work, when I got home it was on the screen to connect the external HARD drive.

    I accidentally closed the macbook yesterday and again once when I tried to log on, I could not and I left it on a white screen while I was sleeping. There is a possibility that he may have launched from the HARD drive when I get home, but if not, is there something that escapes me to force do this?

    See you soon

    Usually start up to a blank screen without the Apple Logo, may report one of the following:

    • Hardware failure
    • Boot drive is not recognized as valid and updated updated
    • OS X essential software is missing, hurt moved or renamed or corrupt
    • A firmware update is necessary

    No matter who, in order to boot from an external drive "bootable", you would normally hold down the Option key until you get a screen that offers a number of devices to try to boot from.

    Alternatively, you can try holding down the C key to try to boot from the external drive.

    If none of these startup options work, then the bootable disc or the USB port on your MacBook Pro can be the question.

    Since you have a Mac pre-2013, if you hold down the D key while booting, the built-in Apple Hardware Test should start up.  This can help to identify hardware problems.

    Concerning

    Hello

    A friend told Tecra A10 and he said that he of a notebook of big business, it seems, he is very satisfied with this laptop. :)

    I asked him about the startup eSATA option and he told me that it of not possible to start from eSATA, but you can boot from a USB storage device. I put t know why you want to start from eSATA, but if you want to boot from your external HARD drive you can connect via the USB port for example. It should work.

    Furthermore, system dual-boot (for example, XP and Vista) is also possible and you n t need a external HARD drive or second for that.

  • Tecra M2: Can I boot from USB/Firewire-drive external HARD?

    Hi all

    How can I boot from an external USB drive?
    The Bios 1.20, 15/03/2004 does not seem to support this on my Tecra M2.

    I have a Maxtor 300Gig external HARD drive that can be connected via Firewire or USB. Usually, I use a PCMCIA card Firewire to connect the HARD drive, which has 3 partitions.

    It would be also possible for a start-up by PCMCIA Firewire?

    Hi dynamitenews

     

    1. are you able to boot to the desktop?
    2. what happens when you try to start the computer?

     

    You must have the DVD drive to start the computer using the disk, you cannot use the external hard drive to do the same thing.

    Also I suggest you to make sure you have defined the start as CD/DVD-Rom as the first choice option in the BIOS. See below the help link-
    http://Windows.Microsoft.com/en-us/Windows7/BIOS-frequently-asked-questions

    If nothing is done, then you can contact the manufacturer support for assistance on setting up the correct boot sequence and check.

    BIOS WARNING-
    Change (CMOS) BIOS/complementary metal oxide semiconductor settings can cause serious problems that may prevent your computer from starting properly. Microsoft cannot guarantee that problems resulting from the configuration of the BIOS/CMOS settings can be solved. Changes to settings are at your own risk.

     

    I hope this helps.

    Yes, there is a way to do this.

    I just did this to install Windows 10 from a DVD on a tablet of 10 Latitude by following these steps:
    (Note: my version of BIOS is A08)

    1. turn off the 10 latitude power.
    2. attach a USB hub to the USB slot unique on the side of the tablet.
    3. fix a keyboard and an external USB CD drive to the USB hub.
    4. now press the button down on the side of the Tablet and simultaneously press the power button for 5 seconds (until see you the screen light up, but will be weak against black unlit).
    5. When you see the Dell logo, start typing on the F12 key (the lower right corner shows the option press the F12 key to choose single startup options)
    6. now start choosing appear with many options to choose from, including my CD/DVD drive.
