Unable to access Safe Mode in Windows 8

I am typing this query using my other computer. Tonight, an installation of the failed pilot, and for some reason, my computer will not start normally in Windows 8. Whenever he tries, it shows me this error message:

System_Thread_Extension_Not_Handled (AtihdW86.sys)
Now, for some reason, Windows is not recognizing that the computer does not start and doesn't give me access to Safe Mode. I tried brewing F8 and SHIFT + F8 or F11 repeatedly on multiple attempts, and he still insists on trying to start normally. I don't have a recovery drive as it was a downloaded purchase. Using the Windows 7 installation disc, I had, I thought he'd let start me in safemode, but she even doesn't let me do.
In the past, Safe Mode would have been a simple way to restore this computer. But I can't do yet, because I can't even mode without failure. It is a serious problem with Windows 8.

Hello

The F8 Safe Mode option has been "abandoned" to win 8...

See if you can access the command prompt with your Windows 7 disc using the method to win 8 below... the menu choices can be a little different, that I don't have a Win 7 disk handy to check...

1) start from the Windows 8 DVD
2) click Next
(3) select repair your computer

(4) select troubleshooting
(5) select Advanced Options
(6) select command prompt

(7) type - Bcdedit/set {bootmgr} displaybootmenu Yes (note the spaces)
(8) type - out

(9) restart

(10) to the start screen, select F8
(11) to select Safe mode with networking

This can then be turned off when you are finished.

(1) run by the lower left corner (Admin) command prompt right-click when Start appears.

  • Toshiba NB200 - startup problem (Windows XP) - unable to access safe mode

    Hello

    I have a laptop Toshiba NB200 with Windows XP. When I turned on, it would not start past the first screen and I couldn't make F8 safe mode.
    The only thing I can do is go into the BIOS Setup, and that's all (press F12).

    The BIOS recognizes the hard drive. Then, I created a USB stick to boot from and that made me a C: quick MSDOS having first changed the BIOS to read the USB first and also updated the BIOS (Phoenix v1.6).

    I'm not clear as to what I do then in the folder c: prompt will not let me run windows and shows just the files on the USB key.
    Should I copy the files from windows to the USB port? In addition, how will I know if the hard drive has failed and that it is unrecoverable (I hope not)?

    Any guidance welcome!
    Thank you

    Hello

    Eventually, there is no Windows OS on the HARD drive and therefore you can not start safe mode or the OS.
    You have a recovery disk or you did backup the image of Toshiba on the USB flash key?

    If this isn't the case, then you need to reinstall the OS of the own Windows XP CD.
    You could build a clean Windows XP USB flash stick that can reinstall the OS.
    I think that this should be possible since you started the laptop backpack.

    Here's a nice instruction how to do this:

  • Access to the Safe Mode on Windows 8

    Hello

    I understand sometimes through troubleshooting or for other reasons, there is a need to access safe mode when using windows 8. What many people do not know is Windows 8 does not use F8 at startup to access the secure mode. It needs to be done inside of Windows 8, himself. The screenshots below will show you how to access safe mode when you use Windows 8.

    On the startup screen, click settings:

    Then click on change settings for PC:

    Thanks for posting your question on the Microsoft community.

    Safe mode starts Windows with a limited set of files and drivers. Startup programs do not work in safe mode, and only the basic drivers needed to start Windows are installed.

  • Safe mode - NB200 Windows 7

    I have tried to get Safe Mode to resolve certain problems and were experiencing great difficulty in getting. Most of the forums and messages say press 'f8' at startup (i.e. the Windows normal option). It did not work.
    I discovered that by pressing "f2" IMMEDIATELY (literally a fraction of a second) after Windows begins to start - for me it was after my startup security key has been registered as I have a HARD drive encryption system, but would otherwise be just after the closure of the Toshiba page which offers the possibility of f2 or f12 that you get to the page that offers you the possibility of pressing "f8" to access the startup options page.

    I hope this helps someone and prevents frustration I've had!

    Thanks for sharing this info.

    Hello

    Thank you for visiting Microsoft Community.

    According to the description, I understand that your PC starts with a black screen. I will certainly help you to question.

    I suggest you follow the steps mentioned below:

    Method 1:

    First try the Startup Repair option in the System Recovery Options dialog box. If this does not resolve the problem, or if you have additional problems manually, use the Bootrec.exe tool.

    Startup Repair is a Windows Recovery tool that can fix certain system problems that might be preventing Windows to start. It scans your computer for the problem and attempt to fix it so that your computer can start correctly.

    Startup Repair is a recovery tools in the System Recovery Options menu. This set of tools is on your computer's hard disk and on the Windows installation disc.

    1. remove all floppy disks, CDs and DVDs from your computer and restart your computer by using the power button on the computer.

    2. do one of the following:

    o If your computer has a single operating system installed, press and hold the F8 key as your computer restarts. You need to press F8 before the Windows logo appears. If the Windows logo appears, you must try again by waiting until the Windows logon prompt appears, and then stop and restart your computer.

    o If your computer has multiple operating systems, use the arrow keys to select the operating system you want to repair, and then press and hold F8.

    3. in the Advanced Boot Options screen, use the arrow keys to select repair your computer and press ENTER. (If your computer is not listed as an option, then your computer doesn't understand no repair preinstalled recovery options, or your network administrator has disabled the.)

    4. Select a keyboard layout, and then click Next.

    5. in the System Recovery Options menu, click a tool to open it.

    Because you cannot start the computer, you may need to create a bootable Windows installation media, and then do an auto repair, and if this does not help then you try to restore your computer to the previous date.

    Note: When you use system restore to restore the computer to a previous state, the programs and updates that you have installed are removed.

    The link provided below might help you to download and create installation media.

    Download Windows 7 Disk Images (ISO files)

    Method 2:

    Try to rebuild the BCD by using the Bootrec.exe tool.

    To run the Bootrec.exe tool, you must start Windows RE. To do this, follow these steps:

    1. place the Windows 7 installation discin the disc drive, and then start the computer.

    2. press a key when you are prompted. Select a language, a time, a currency, a keyboard or an input method, and then click Next.

    3. click on repair your computer.

    4. click on the operating system that you want to repair, and then click Next.

    5. in the System Recovery Optionsdialog box, click command prompt.

    6. type Bootrec.exe, and then press ENTER.

  • mode off safe mode on Windows 7.

    Is there a sure way to turn off the mode without boot failure in windows 7? My kids tried to use it to install programs without my permission. I have to find a way to turn it off. I know that this means that I will not have access to safe mode when I need, but I'm fine with that. The worst cases are re - install the entire operating system, and I have periodic return on the system, so I'm going to re - install OS when necessary.

    Internet research is inconclusive. Some say it's impossible. Some evoke a commercial which some said work tool while others say does not.

    Of course, all accounts on my PC have password.

    A point in that way that I'm not too sure will work for sure:
    "Administrator" account and activate the password on it, so when it goes into safe mode, it always need password.

    I already did, and 'Administrator' account now requires a password in safe boot mode. It's a sure way to impose security on safe mode? Or are there still ways to circumvent security in safe mode?

    Authoritative answer?

    Thank you very much.

    Hi Saleta,

    Sorry for the late reply. From your problem description, I understand you have safe mode in your computer. Safe mode is a Windows utility that allows you to use your computer outside of your regular Windows session. Using this option is convenient to edit or remove entries of system or software malfunction, that is usually done when troubleshooting your computer. Your administrative privileges using existing, you can disable a Windows password using the Windows Safe Mode.

  • Vista system does not start after installation of windows update 10thFeb2010. Only start in safe mode. Windows Update does not open

    Updates to auto (windows Update) using.  Downloaded automatically update yesterday (10thFeb10) and when I shut my computer down it started to install them - as usuall.  However start my computer than this 11thFeb10 am and he began to run through regestry files when starting up.  Then it is impossible to load windows.  Just went to a blank screen.  Rebooted several times and were able to start it in safe mode.  Tried system restore but the same thing happens.  Obviously there was something to this update that 'changed' my computer and I'm not happy about it!  Also thought that there could be new updates (perhaps to fix the last update) but I can not even Windows Update to open it.  Tried online and he tells me that I have never downloaded updates and that none are available.

    I use Windows Ultimate x 86.  I hope someone can help me!

    Got a response from Ms.  Good all who have this problem - you have an ATI Radeon graphics card?  Driver is causing the conflict.  Uninstall all the stuff ATI goes on ATI web site and install the download of 'single driver '.  Reboot and then you can download and install other fancy programs that come with your graphics card.

  • Error code 0x000000TF not able to boot in safe mode on Windows XP computer.

    Original title: xp suddenly will not start in safe mode.

    I haven't added any software and I don't seem to have any virus, any help?

    error message 0x000000TF 0 x 80042000, 0x00000000, 0x00000000)

    Try at least the basics:

    1. first of all, check the intregity of your player. If it is not quite right, you will not be able to start. If fix you (by running chkdsk), maybe it's ALL that is necessary. At the command prompt, run this command:

    Chkdsk /r

    (There is a space before the slash). I know that that page has a slightly different order, but the /r switch (to repair bad sectors and recover readable data) is all that is necessary. For more information, see:

    http://vlaurie.com/Computers2/articles/Chkdsk.htm

    Plan for several hours to run chkdsk/r. But this could very well be all that is necessary.

    2. If still no joy, you'll need to fix your boot.ini file. Until you do this, you will have to remove some attributes of this file, so you can change (the flags 'Hidden' and 'System' and 'Read only'). So, at the command prompt, enter these commands:

    C:ATTRIB H C:\\BOOT. INI
    C:ATTRIB R C:\\BOOT. INI
    C:ATTRIB S C:\\BOOT. INI

    Then, delete the boot.ini file. It is fine to do, especially if there is something wrong with her! You create a new.

    DEL BOOT. INI

    Now, rebuild your boot.ini file:

    BOOTCFG /REBUILD

    (even when there is a space before the slash)

    Continue to follow the instructions on this page:

    http://tech.Icrontic.com/articles/repair_windows_xp/

    Add installation to boot list? Enter y

    To enter load identifier, type:

    Windows XP Home Edition (I think that's what you have. For XP Pro, type "Windows XP Professional")

    To the operating system load options, type:

    / / fastdetect / noexecute = optin

    (even once, there is a space before each slash)

    Note that in case your CPU has NO other buffer overflow protection, you must not enter the "' / noexecute = optin" switch. " But it's a safe assumption you have and you should use it. Google or ask here if you don't know what CPU you have.

    For pour ecrire to write the newly created boot sector on the hard disk, type the following at the prompt:

    FIXBOOT

    (And press on Y to confirm).

    I mean chkdsk /r first because that's all that would be necessary. But you also have other instructions. If still no joy, restoring the so-called manual system might work:

    http://support.Microsoft.com/kb/307545

    If still no joy, I'd go for the Clean install (of course, you can also try a repair installation before that gap very last effort, but repair installs can sometimes be very difficult).

    Have you confirmed that all your data is backed up. If you perform a clean installation, you erase your hard drive, you know!
