Z575 will not boot from the hard drive or restore DVD

Need help on a laptop Z575 age of 2 years that immediately after an automatic update of windows, will not start either from the hard disk or restore DVDs (blue screen). Does not start in safe mode, not booting from a rescue of third party DVD. Attempt to start, it will show you the ability to start the Startup Repair tool. Repair shows that it is unable to fix with the detail following problem error messages:
Signature of the problem 1: 6.1.7600.16385
Signature of problem 2: 6.1.7600.16385
Signature of the problem 3: unknown
Signature of the 4:21200196 problem
Signature problem 5: auto failover
Signature of the problem 6:7
Signature of the 7 problem: bad driver
OS version: 6.1.7601.

Normally think that the hard drive has failed or that windows update caused a software problem, but the inability to boot from any restore disk that makes me think that there is another serious problem with the hardware of the laptop.

Any help would be appreciated. THX

Additional note: when you try to boot from a restore disc, blue screen, error message:
Stop: 0x0000007B (0xF78DA640, 0xC0000034, 0x00000000, 0x00000000)
It is a hardware failure that cannot be restarted soft.

I also removed the hard drive and RAM, reinstalled and rebooted, no change.

Additional note: I was able to access the hard drive with a recovery of old program, focused on the (SpaceFM) ram charged through the DVD player. Hard drive data appears intact. Still does not start from the hard disk or a DVD of windows system.


Thank you. Rather than buying a 4 GB or more large key USB comes from put this into hard drive replacement. Installed correctly, boots very well now. No other error of the optical drive... and no explanation I can see, but that's it.

Unless something else pops up we'll just call cela a HARD drive failed after 2 years of common use. Thanks again.

  • can not boot from the hard drive

    There are various reasons why this error message:
    In most cases this error because the laptop is trying to boot from a HARD drive or flash drive that is not configured correctly. Maybe the drive is not bootable or not compatible.

    It would also be possible that some sectors on the HARD disk, HARD drive failures are corrupt or BIOS is damaged. NTLDR error messages may also appear if the master boot record is damaged.

    In your case I recommend that you format the first HARD drive before booting from the hard drive CD7DVD external using Win XP CD.

    By the way: you must add SATA driver to CD Win XP using nLite.
    The SATA driver is placed on the European driver Toshiba page in the Intel Storage Manager

    The SATA driver is needed to recognize the HDD by Win XP!

  • XP does not start from the hard drive

    I have an old pc under win xp. It does not drive start hard when it starts. I always have a cd/dvd in master dvd for it to start windows players. Can anyone help?


    Hi herikhi,
    Change the start of the base system (Input Output) BIOS setting to boot from the hard drive.
    Consult the manual of the manufacturer, to do the same thing.

    NOTE: BIOS change / semiconductor (CMOS) to complementary metal oxide settings can cause serious problems that may prevent your computer from starting properly. Microsoft cannot guarantee that problems resulting from configuration can resolved BIOS/CMOS settings. Changes to settings are at your own risk.

  • (Redirected) Cannot boot from the HARD drive on dell n5010 with SSD and HARD drive installed

    I have my old dell n5010 (15R Inspiron) with SSD (Samsung EVO 840 120 G) installed on the main drive Bay and the HDD (Samsung HJJ 500 G) on the optical drive Bay.

    It is a typical way to add an SSD on such an old laptop (bought from dell.com.cn in 2011).

    My Windows 10 operating system has been installed on the SSD using Samsung Data Migration software, so the previous C drive was pointless. So I formatted and installed an operating system Ubuntu 14.04 on it, hoping the grub OSs double beginning located on the HARD disk.

    However, I find no the Dell bios boot option to boot from the HARD drive installed in my optical drive Bay. All the choices are 'Hard Drive', 'Network' and 'Diagnostic '.

    But I was definitely sure that my bios program has detected the SSD and HDD with information on the main menu of the bios.

    And the LED on the optical drive Bay was immediately once I pressed the Start button on my laptop.

    As a general rule, all things were right except for options of the bios boot.

    Is there a way I can boot from HDD (with installed Ubuntu) while remaining has my SSD on the main drive Bay? I don't want to swap their positions, because the SSD is super fast on the main drive Bay.

    I have alse won't migrate 10 Windows to the HARD drive and reinstall Ubuntu on the SSD, because I'd like my windows be loaded quickly.

    Someone at - it the same problem with me?

    Any suggestion is appreciated!

  • A33 satellite will not start on the hard drive even after the installation of the new system

    Hello, I need help, my A33 does not start on a hard drive. It is to see the drive hard in the bios and even by operating the drive when you go to install. But as soon as it will boot to the hard drive, it is just a black screen. It is very strange that you can see the hard drive in the bios and even with a diagnostics disk. I can see, scan it and check it by starting with a diagnostic disk, but when I start the computer, it doesn't do anything.

    Help please!

    Stand by. Your ad is so confused. When you read can you understand what you wrote?

    BIOS recognizes the HARD drive correctly, no?
    When you use bootable disk for the installation of the OS is properly recognized HDD?
    You can install OS using the original recovery disc or by using the Microsoft installation disc?

  • 8000 elite: try to boot from the hard drive

    After placing a ssd, I get this notification. nothing else happens.

    I checked the bios, but I noticed that I can not change the boot sequence (ssd hard drive first, the other second place) so I changed the sata cables too the ssd is the startup disk.

    someone who can help?

    the ssd already has an operating system installed

    Sorry, from your description, I thought you might have "migrated" Win10 from the HARD disk to the SDS, and when people do this by copying partitions, they almost always forget migrate partition, including the bootloader files.

    So you did a clean install of Win10 for the SSD?

    If this is the case, you might be able to fix it by running the win10 installation media startup repair.

    To do this, you will need to use the link to the installation media to download Win10 and burn a DVD or create a USB key: http://windows.microsoft.com/en-us/windows-10/media-creation-tool-install?ocid=ms_wol_win10

    Note that when you download and build install media, the default tool corresponding to what is already installed on your PC (as in home for the House, and 64-bit to 64 - bit).  While you CAN change these settings, are NOT.  If you do, the media that results will be different and will force you to enter a NEW product code.

    Then, follow these instructions to run the Startup Repair tool: Doing - Startup Repair

    You may need to do this same series of steps three times.

    Good luck

  • Cannot boot from the HARD drive in AHCI on Satellite C mode

    I tried to get this satellite working for these past two weeks. I think I've tried all of the suggestions I found on this forum and others.

    My problem: I can not boot from drive c: in AHCI, only in compatibility mode. I can boot from the D: (recovery partition) in AHCI mode. When the recovery is complete, and when it gets to the first reboot, try to boot from the system newly created on the C:, I return the compatibility mode.

    I replaced the drivers on the C: drive.

    I extracted the AHCI drivers and copied in the root of a USB bootable. I try to do a clean install of windows 7, I get to where it shows the partitions. He tells me that it can not load the system on any of the partitions, I the AHCI mode (if the mode is set to compatibility it will load the system in one partition).
    I select "load drivers" and select the driver in the root directory, it loads the driver and then reports that it can not load the system on any of the partitions.

    I'm puzzled. I acquired pilots everywhere, the last set of drivers I used to try to do a clean install, I have acquired the Canadian official Toshiba site.

    Does anyone have any suggestions?


    BTW, this is Windows 7, I'm trying to get back to.

    Can someone help me with this?


  • Windows 7 for Lenovo G50-70 - the computer will not boot from the CD

    Hello world

    I hope that someone here will be able to help

    I bought a new laptop with Windows 8.1. I want to install Windows 7 on that I know well because I can't use the new windows. I changed the settings in the BIOS to get the machine to boot from the CD, but it won't be fair. I also tried to restore the system to boot from the CD, but it installs just the Windows pre-installed, new instead. Also, I can't access the CD from the drive while all my other computers are capable of (what is strange)

    Can someone help, please?

    PS. : I can turn on the computer through the small "boot botton" on the side and select the DVD drive to boot from. But this is not followed by the message "Press any key to boot from CD" and the computer starts just W8 yet;

    I contacted customer service and followed your advice. They refused to help him on the ground that there nothing wrong with the machine in their opinion, and since I wanted to change operating system. All preinstalled spyprogrammes Lenovo has been erased with this downgrade. So far, I've owned a laptop computer brand new and expensive for a year I used only to waste my time, trying to make it work, that was not why I bought it in the first place. What a RIP-OFF!

  • HP Pavilion p7-1414 will not boot from the CD


    I recently bought your desktop HP Pavilion p7 1414, I am trying to boot from a CD to reinstall Windows 8 - I put the CD to start first in the BIOS, but when I restart the computer and I have the CD, "press any key to boot from the CD" is not displayed.  It starts just directly to the computer HARD disk in Windows to connect.

    I have 64-bit Windows 8. 6 GB of RAM and a terabyte of HARD drive space.  I'm looking to reinstall Windows 8 for a new start.  Any ideas why it won't boot from the CD?

    Very happy!


    You must go into the BIOS and enable the legacy Mode and disable secure boot.

  • Tecra M3 PTM30A will not boot from the cd to reinstall windows

    Hi all

    Totally new here and I have a question. I replaced the hard drive in the laptop, the old man died.
    I set the bios to boot from the cd. He reads the Windows XP cd for a minute then jump to trying to boot on the network adapter.

    Do I need to have the cd of recovery or must it be able to boot from a plain old XP cd?
    If it can boot from a normal cd is the stuffed ROM or am I missing something?

    Thanks in advance to anyone who can help you.


    > I replaced the hard drive in the laptop, the old man died

    Your new hard drive is recognized by the Bios?

    > Do I need to have the cd of recovery or must it be able to boot from a plain old XP cd?

    You can use a recovery (if available) disk or Windows disk copy. In the Bios, you must set the Cd/DVD-ROM as 1st boot device and press F10 save and exit. Turn it back on. Thus, your computer you should start the installation of the Cd drive.

    I would like to know if there is a way to use the restore with norton CD and usb driver and password screen (or where I can get the password?).

    Thank you!

    What password do you mean?

    and what recovery CD do you use? The image on the Toshiba Recovery CD is locked and cannot be extracted.

    It turns out that you cannot start or install the OS on the USB key!
    You must boot from the CD/DVD compatible player that can be connected to the PC card slot.
