SSD external via USB does not start by default

Hello Apple community.

I have a problem with my new external SSD. Given that the base model Mac Mini end of 2014 comes with a disk HARD 5400 RPM drive, I wanted to go to an SSD without having to tear the whole unit. I wanted to exhaust the option 'boot from USB' and I'm having a strange problem. I cloned my Mac to the new drive SSD and slapped in a box set of the speaker. I connected via USB and changed my 'startup disk' to use the external SSD drive. However, it does not start on this unit automatically. When I reboot and discovers the "boot manager" I see the USB being initialized automatically. After disconnection / re - plug the drive in, it appears as a boot option. Once it is initialized, everything works fine and I can boot into El Capitan without any problem using the SSD.

I am trying to find a way that I can get the Mac to initialize the SSD to the boot upward and choose default. I don't want to have to re - connect the drive whenever I want to start on the SSD drive... Any help and suggestions are greatly appreciated!

My equipment

===========================

Model Base of Mac Mini (end of 2014)

What unit do you use for the SSD?

Can you provide a link?

If the SSD is delivered with a box to provide a link to that,

How do clone you for the SSD? What app did you use?

  • OfficeJet 4500 G510g: Windows 10 Driver not recognize OJ4500 via USB. does not scan

    After the upgrade to Windows 10 JO 4500 would print not scan. (From August 2015) completely uninstalled and reinstalled the latest driver. The Setup program does not recognize that the printer has been connected via USB (the button "Next" is never active). I was able to print but never able to scan.

    Launch the center of solutions results in:

    HP solutions Center can not run because your device installation is not complete.

    Today, on 20 October, I downloaded another driver updated (September 2015, 140_408.5), uninstalled all the previous HP printer software/driver and tried again. The pilot 'up-to-date' has exactly the same problem - not recognizing that I have now connected to the printer via the USB port (trying various ports on the PC) and never goes to the "following".

    I clicked the help button.

    1 said to confirm that the device is connected and powered. Click back to try again. No luck.

    3. Affirms that if the problem persists, check the troubleshooting section in the Readme on the CD-ROM. I have no CD so no luck.

    Then, I couldn't leave the Setup program except by using the Task Manager to kill the process running.

  • Windows 7 Home Premium does not start and an external monitor connected via DVI to HDMI Cable

    I have a Dell Inspiron 531 desktop computer with a NVIDEA GeForce 8400 GS video card.  This video card has the following outputs: DVI, VGA and S-video.  When I connect it to my computer via the VGA port to PC to my Sony Bravia KDL-40XBR4 monitor port, the machine starts perfectly.  If I connect via a HDMI cable to one of the HDMI monitor DVI ports, the screen displays the video BIOS, but turns black when the operating system begins to load.  If I connect another monitor to the VGA port, yet once the machine boots fine, but if I connect the monitor to the computer and the Sony Bravia, once again the machine does not start.  The strange thing is that if I boot with only the connected computer screen and then plug the DVI to HDMI cable, then Windows 7 sees the Sony Bravia monitor very well, and I can extend the desktop.  If the machine mode 'sleep', both monitors work very well to wake up the PC.  So, if the Sony Bravia is connected alone or with the computer screen, the machine does not start (the screen will display 'go black' when the OS starts to load.)  I tried to run Windows in Mode safe, but he won't either.  I have all the updates of Windows applied and have installed the latest drivers from nVidea so.

    Hey Chris,

    First of all, about climbing, is not a technical support; This is a community forum where MS moderator and contributors are involved.  Now to your question ~

    It's very strange that the PC does not start when this unit is connected, but works fine when connected after the fact.  I've seen several cases where a hardware configuration of uinsusal will prevent a PC to boot.  I think that the culprit may be DVI to HDMI Cable that you are using.  If I were you, I try to connect the PC to a DVI monitor and see if it boots normally.  Also, see if the monitor can prevent another PC to start when it is connected directly via the HDMI.

    Good luck! Let us know how it turns out.

  • HP envy Phoenix: win 7 does not start with connected external hard drive

    I have a desktop HP Envy Phoenix with i7 chip and an SSD for the OS.  If I connect via USB external drive of 3 TB WD for the backup of the system does not start while it is attached.  The pc seems to be trying to boot from the outside, can't find the OS and does not start.  It will start fine with small external drives connected.  It is the size of the disk? Is there a way to fix this?

    Hello

    The WD drives seem to pose problems of my potential.  I have used other brands such as Seagate and Hitachi without running into problems with external USB drives causing the system to boot.  Maybe it's the USB adapter that I use which does not cause starting problems.

    @tpetras

    I used the adapter HP USB 3, which uses drivers NEC or TI and has never had a problem starting via a USB external (non - WD) readers.

  • Flow 10 7 HP - Windows does not start, I can't get into recovery 8.1 because cannot boot from USB-HELP Please!

    Hi all, I'm new here!

    I am (excuse me: has) with a stream 7

    A few days ago, I tried to install Windows 10 TP renovation 8.1 with Bing. After a while of waiting, he managed, but unfortunately I have forgiven to in SSD Tablet hp drivers, thinking that they were not necessary. If the touchscreen, WiFi and all the other stuff has failed. After I've got collegated by OTG, a keyboard and a mouse, that I managed to use Windows 10.

    Try to install the drivers, my fault, I opened a .exe from Realtek (perhaps for audio), Tablet asked to reboot and after that I can't access Windows anymore.

    I tried to start Windows 8.1 from a USB key, but it does not start, the same even if I disable secure boot.

    With disabled bitlocker Windows gives this error

    In the start option, I set these settings

    I put the USB in this way:

    The stream does not consider the USB absolutely XD

    If I turn on again the secure boot Windows gives this error (which 99% is caused by the .exe I installed):

    Restart the flow some time with secure boot it goes in a menu (where touch screen works) where there are a lot of options to reset Windows, but none of them doesn't work. If I try to format in this menu it asks password for my account, but it does not accept the mine :/

  • Satellite A30 does not start with the USB device connected at boot time

    Hello

    I have a Satellite A30 and sometimes it does not start.
    After turning on, not even the BIOS starts.
    even if sometimes the BIOS starts, but the OS does not load.

    I figured out that its related to USB devices connected at boot time.
    If no USB devices are connected, it starts without a problem.
    Even if the start-up is suspended, as soon as you unplug start it BIOS USB devices.
    Its ok to connect USB devices later, once the system has started.
    I disabled "removable devices boot" and "network startup."
    just in case, but it makes no difference.

    BIOS is version the most recent (1.70) and it comes up with all kinds of USB devices.
    printer, mouse and (self-powered) external USB hard disk.

    Is this a known issue?
    There is no known workaround solution?

    Hello

    I put t know why this happens, but it has to do with the BIOS.
    The same thing happened on my old laptop. I couldn't start my unit while the USB printer has been turned on and connected.
    The only solution is to disconnect the external USB device during the boot process.

    RSY you should check if the order of boot in the BIOS has been on the HARD drive first.

  • Satellite A660-186 does not start when the USB nano-receiver is connected

    Recently I bought a mouse a4tech g7-750 with the nano-receiver into usb port plug.
    After the nano-receiver is inserted into the USB before lighting, computer laptop does not start.

    Only the cursor is displayed, so that it is displayed before the screen with the ability to enter the F2 BIOS or select the F12 boot device.
    Without the nano-receiver laptop runs without problem.

    Any advice?

    Thank you much in advance.

    During the POST (power on self-test) all parts laptop as RAM, motherboard (also of connected devices) is enabled.
    If a problem (compatibility problems, etc.) would be detected during POST, then the laptop would not initialize correctly.

    This mouse nano-receiver is unknown to me and I m not very well what s wrong with this unit, but I doubt that this problem is related to the laptop.
    I guess that the laptop starts properly with other devices connected to the laptop. right? Well well, in such cases, there s no question cell phone but the 3rd unit affect the functionality of the laptop.

  • C870-19(r) satellite does not start with the new SSD

    Hello

    I will update the Toshiba Satellite C870 19(r) with a Pro 840 Samsung SSD, but it does not start.

    He said: not found system.

    Post edited by: joch333n

    None found system means that there is no system installed on the SSD drive...

    What you trying to do?
    You start from a disk in order to install the new system?

    In this case, you should disable startup secure in the BIOS.
    I also recommend moving from UEFI mode MSC!

  • Satellite C660 does not start on disc or USB

    My Toshiba Satellite C660-DSC0QE app, BIOS version 1.80, will not start Windows more - it just goes to the dreaded black screen with white cursor.

    I tried a system Win 7 recovery disk, a USB with software from Kaspersky on her recovery and even a full Win 7 installation disc, and it does not start at one of them.

    The boot order is set correctly, (optical drive or USB port) devices are read, but their initialization never actually in them - there is an obscure error message, or it acts like they weren't there at all.

    The obvious answer to these forums seems to be disable secure boot mode and then switch the to the CSM UEFI boot mode. Easier said than done - the menu options don't exist at all in my BIOS/CMOS screens.

    Finally, I see no way in the instructions to get a BIOS update occur without being already in Windows on the PC - http://aps2.toshiba-tro.de/kb0/HTD9502M10000R01.htm I'm assuming that the BIOS version 2.00 would have these options.

    Any help gratefully accepted!

    Hello

    I assumed that you have a white blinking cursor in the upper left corner.
    Is this correct?

    These symptoms appear where the system can not find a boot device (HARD drive) or memory problems (RAM module).

    First of all, you said that you have UEFI / CSM boot mode in the BIOS settings.
    So I m asking you what parameters of start mode appear in BIOS exactly?
    Find you these settings in the right area?
    Usually, you should have an area (tab) called security in the BIOS.
    In most cases, you will find a safe boot option, but the Satellite C660 does not support this option because it s too old.
    But the startup mode (UEFI /CSM) should be available in the BIOS. Check the settings in the BIOS of the system area

    Anyway, as I said above; It could also be a memory problem, so I recommend you to check if the memory is OK.
