• 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.

• Satellite NB10t-A-101 refuses to boot from any external media

  I just bought a NB10t to the United Kingdom and try to boot to a bootable USB key

  I noticed that the BIOS on this particular model is UEFI mode only, which, in itself, is not a problem because users can sign their own operating systems with a certification authority and use them, but this laptop refuses to boot from any external environment... or even to provide an error message.

  I changed boot priority in the BIOS and USB moved up
  I disabled the Secure Boot option in the BIOS
  I tried all 3 USB ports as well as 3 different drives (NOTE: THESE WORK FINE ON the 3 OTHER SYSTEMS, a dell desktop/laptop computer and a computer acer laptop)
  I also tried different distributions (Debian & Arch)
  I used several installation methods (hard install of Unetbootin/Full/Rufus etc...)
  I tried all your currently released BIOS versions (delivery with V1.0, V1.1 - Jan Feb - V1.2)

  After trying all these when you press F12 at startup, the shows start menu but when you select a device, the system continues to initiate (Win8) HARD drive

  After Googling around, I noticed that you have unlocked 2 BIOS updates I tried all versions of these and still the system refuses to boot in my selected device

  Can we expect more updates of the firmware in the near future? Is there a way to work around this problem to start my chosen OS? Is there an option of CSM?

  Hello

  Your laptop was equipped with the new processor Intel Celeron 2810 n that belongs to the Bay Trail-M architecture.
  This new * Intel Bay Trail * technology is only supported systems that support UEFI and systems (Win 8, 8.1 Win) and, therefore, the UEFI / CSM boot mode option isn't available in the BIOS settings.

  _So you can install only a system capable of UEFI

• How to boot from a USB - Portege R500 flash drive

  Hello

  I have a Portege R500 running Windows XP, presented about 2 years ago and recently contracted a virus that has infected some of the startup files as the minute I connect it disconnects again, even in SafeMode! The quickest way I can think sorting is to reformat with the XP Recovery disk and reinstall windows.

  Problem! The CD/DVD drive on the computer laptop stopped working earlier, tried almost everything in the thread on this site, but had no luck.

  So my plan was to boot from a USB flash drive and do it this way. However in the boot parameters I only have the options of HARD drive / floppy drive / CD-ROM / LAN, none of them work. Does anyone know how to boot from USB flash drives?

  Any help would be really appreciated

  Hello

  As far as I know, it should be possible to boot from USB FDD

  I don't know if you would be able to boot from a USB flash drive, but it of certainly worth a try m

  Generally, you can try to press the F12 key when the laptop is turned on.
  A start menu should appear on the screen, then you should see all bootable devices.

  PS: as far as I know the USB startup was available in ToshibaHWSetup (tool of Toshiba which changes the settings of the BIOS under windows OS.) So I guess boot from USB must be possible.

• Portege R100 - boot from the external HARD drive

  I have a Portege R100 and the HARD drive has failed. I installed a new HARD drive and I have the Toshiba recovery disks. I tried to boot from a generic USB CD-ROM but the laptop did not recognize.

  I have a disk of Toshiba USB drive it does not recognize and I have a restore disc but I don't know how from there. Do I have to buy a CD external Toshiba and if so, which?
  Any useful suggestions?

  Hello

  Boot from the external USB CD/DVD drive is not possible.
  You will also be able to boot from USB HDD!

  If you want to boot from the CD, you must use a compatible PCMCIA cards (16-bit and 32-bit Cardbus) CD/DVD drive.

• Qosmio G20: Possible boot from a USB device?

  Dear all,

  I am writing for you good people was whether it is possible to start a Qosmio G20 via a connected USB device, an external hard drive.

  I wonder if it is taken in charge (or tolerable) within the limits of the current Qosmio G20 BIOS and/or if any could attempt on my part to make taken in charge (i.e. are there buttons I can push levers, I can pull or numbers I can play to get there).

  The reason why I have is that my laptop has a multitude of technical difficulties that point to the hardware failure, among them a vertical line on my screen and a problem with my optical drive, making it impossible for me to write a CD or DVD.

  In the unlikely event that the good folks at Toshiba support are forced to replace the hard drive (or the system) it would be nice to have a way to restore the system to its current configuration (in this sense, I'm looking for a way to create my own bootable recovery disc produced) however the lack of functionality in the Department of optical drive ties my hands a little (I can't create a recovery of) product custom CD/DVD but I might create a product on my external HARD drive recovery partition).

  Thus, it would be useful to be able to boot from a USB, not essential of course as any disk image could be comfortably written to disk through my soon-to-be renovated system (of course it would be quicker to start just by the USB bus and avoid all this nonsense).

  Sincere greetings,
  Lee Hyde.

  Hello

  I am sorry to say that you will not be able to boot from the external USB HDD. The BIOS does not support this feature.
  According to different threads here in the support of forum Toshiba Qosmio G20 BIOS supports these devices to start:
  Floppy USB drive, 1st/2nd HDD, ODD, network (LAN)

  As you can see it s possible to floppy USB FDD but not the USB external HDD

• Boot from an external HARD drive via USB

  I have an 8200 Elite SFF and wants to start an alternative system (not Linux, but * NIX - like BONE) of a disk external DRIVE, connected via a USB port. My main operating system is WIN 7 64 bit, but for some special tasks I´d like to use the alternative OS. It worked without any problem on my two previous stand-alone - elected USB as a boot device in the BIOS boot menu and it starts fine.  However, on my Compaq 8200 there no USB option in the start menu. However, when I connect the external HARD drive to a USB port, the name of the HARD disk appears in the start menu, but again, it won't start him.  Have heard that there is a tweak to fix this, or maybe I m wrong. Alternatively, my stand-alone motherboard just can´t boot from an external hard drive via USB? Any ideas?

  Yes,

  Unplug everything plugged to the computer except the keyboard, mouse and monitor.

  Then use this method to Flash the BIOS.  It's the best way to go.

  USB Device Flash BIOS DOS

  BACK Flash (DOSFlash.exe, FlshUefi.cpu) is the Flash BIOS DOS compatible system utility that can be used from a bootable BACK storage device (where the 'BACK' refers to a number of operating systems such as FreeDOS, DR - DOS or MS-DOS). FlshUefi.cpu is the driver required for DOSFlash.exe. To Flash the BIOS of the system to a bootable USB storage device, you'll need to copy the contents of the BACK Flash file on the USB device, start the PC from the USB device and run the DOSFlash application. To see a more complete description of the BACK flash utility, view DOSFlash.txt located in the folder BACK Flash. This folder also contains the required binary BIOS image.  The binary image file is named xxx_MMmm.bin , where "xxx" is the family of BIOS, 'MM' is the major version number and "mm" is the minor version number.  This file can be copied to the root directory of any removable media USB for use with F10 setup option «Flash system ROM»

  The display of the folder BACK Flash content

  The links on this post do not work. I copied the section from the BIOS flashing instructions for the specific section you need.

• 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.
