• Windows could not start on Satellite L510

  HI :)

  I'm not very tech savvy, I've only had my laptop a month. And yesterday, when I turned it back on I got this message...

  Windows could not start. A recent hardware or software change might be the cause. To solve the problem: Insert your windows installation disc, and then restart your computer
  If you do not have the disk, contact your manufacturer computer or system administration.

  file: \boot\bcd
  status: 0x000000f
  Info: an error occurred trying to read the boot configuration

  I have been all over these forums and the internet looking for a solution, but no luck. It's the weekend, so I can not communicate with the service line.
  I would appreciate a process step by step what it is, that I need to download or reset. I do not have the windows installation disc, because it did not come with my laptop.

  I really appreciate your help in advance ;)

  Hello

  Well, the error message says everything to me. Insert the Windows disk * or * contact manufacturing (Toshiba). ;)

  By the way: it would be interesting to know if you can boot into safe mode. Check it!
  If so, you may start the HARD drive recovery. Therefore, select Repair my computer in the Advanced Start menu and follow the instructions on the screen.

  Yes, with the laptop didn't come a disc, but you can create one!
  Please read the operating manual always first.

  Now it s too late to create such a floppy, but you can order directly into a new Toshiba:

• Once I turned on the computer I got the following message: Windows could not start because the following file is missing or damaged. System32\Drivers\Ntfs.sys

  I just download Microsoft Office 2010 Professional and then turns off the computer with XP operating system. Once I turned on the computer I got the following message:

  Windows could not start because the following file is missing or damaged;

  System32\Drivers\Ntfs.sys

  You can try to repair this file by starting Windows Setup using the original Setup CD

  Select 'r' in the first screen to start repair.

  Then, I started the computer with the Original installation CD and press 'r' by following the instructions. Then, I received this message:

  1: C:\WINDOWS

  Which Windows installation you want to connect?

  (to cancel, press enter)

  What do I put here?

  You must first start on doing something so USB drive a bootable Hiren.

  Here's how:

  I'll recommend you use Hiren boot CD (it will go also to a flash/USB stick/USB).

  It's good for you, because there a lot of tools more on that on the Recovery Console CD of XP, doesn't your administrator passwords and you will not have to futz round in your BIOS, if any afflicted system has SATA drives - Hiren can deal with this.

  You will have a bunch of great tools that you have in XP... Recovery Console an editor of the register, adjustable password and an office that resembles Windows XP so you will feel comfortable flexibility.

  You can easily copy your personal data (documents, pictures, music) to an external drive.

  A system of work, start by downloading the latest version on Hiren Boot CD from here (it is a substantial download but worth it):
  http://www.hirensbootcd.org/download/    (look to the bottom of the page).

  Unzip the Hiren to a folder where you can find it.  There's a Hiren. BootCD.15.x.iso that you have to then.

  Hiren was instructed to make a bootable USB drive that you can use, but it takes you first burn the .iso to a CD image file and a few other measures, so I suggest another way and here's how:

  Download RUFUS 1.3.2 or whatever the latest version is here (read a few things on the page so you can learn more on this subject):

  http://Rufus.AKEO.IE/

  I will warn to be careful that don't accidentally format you a hard disk - don't forget your USB key is in and know what the drive letter!  This part makes me still a little nervous, so be careful.

  Launch of RUFUS and all default values should be fine for the device, choose letter of your USB drive, quick tag format FAT32, it if you want and in the Format options box, click on the little icon that looks like a CD and a window will open.  Navigate through this dialogue to point to the folder that contains the Hiren. BootCD.15.x.iso that you have unpacked above and the box should change to say the image ISO (RUFUS includes the Hiren ISO file).

  Double check you have the right device selected in the top (NOT you HDD) click Start, acknowledge receipt of the warning and let it finish (it will take a little time) it copies the files.   Hiren ISO is also a good size.

  When RUFUS is finished, it will say "DONE" at the bottom.

  Put the USB in the afflicted machine and reset/reboot and regardless of the button you press to get a boot menu where you can select the USB drive as first boot device (it's F11 for me).  If you do not see a start menu choice, you will need to set your BIOS to boot from USB first instead of the HARD disk.

  When the Hiren menu displays, choose the XP Mode of Mini and it will start loading (slowly from a USB key) and finally, you should see a windowsy looking for office.  You should recognize the part and feel uncomfortable, but it is not your office - the office of the Hiren!

  Remember: you do not start on your hard drive, - you started in the Office of the Hiren.

  A way to check the drive for errors is to open my computer and right-click on your afflicted player and choose Properties, tools, error, check checking now... put a check mark in the boxes and then start.

  Sometimes that works, then you can also click on start, run and in the type box:

  cmd

  Click OK to open a command prompt window and enter the following command (assuming that XP is installed on your C drive)

  CHKDSK c: /r

  This disk check can last a long time (perhaps several to several hours) depending on the size of the volume, the amount of data on the volume and what the disk check finds to do.  You may need to run more than once.

• Windows Vista: windows could not start error. is suspended from the "Microsoft Corporation" loading bar then black screen BIOS not acpi compliant

  After you have installed the driver for the zune hd, I was asked to restart my computer. After the reboot, start froze on a white screen. I've seen this before and it is usually because of some connected usb components. so I manually powered down the Tower, disconnected the cable from zune and restarted. This time a screen saying that windows could not start, "launch Startup Repair tool" was recommended. Select this habit makes the startup hang to the progress bar from Microsoft corporation, then to a completely white screen. Although strangely, once only a blue error screen appears which says that the BIOS is not acpi compatible. I can't restart with F8 to go into safe mode, "windows error recovery" still appears. "Start windows normally"produces the same results as the tool to restart launch system. " I have a drive to upgrade to windows 7 and a windows XP upgrade disk. the disc of windows 7 hangs at "starting windows" and the XP disc gives a blue screen error: stop: 0x0000007B (0xF78D2524, 0c 0000034, 0 x 00000000, 0 x 00000000)

  I think I have a BIOS problem, but I don't know how I could continue dealing with the repair. I have no success update the bios from usb flash. Any idea is appreciated.
  Update: managed to start with F8, choose to boot in safe mode and loading hangs after "load: \windows\system32\drivers\crcdisk.sys"***.

  Hello

  1. What is the exact error message when Windows Vista does not start?

  2. you have the disk Installation of Windows Vista operating system?

  I suggest you change the mode of RAMA to IDE in the BIOS. You can contact the PC manufacturer for assistance.

  Note: BIOS change / oxide of additional metal (CMOS) semiconductor parameters incorrectly can causeserious 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.

   

  In addition, perform a check disk in Windows Recovery Mode.

  (a) Insert the Windows Vista installation disc in the disc drive, and then start the computer.

  (b) press a key when the message "Press any key to boot from CD or DVD".

  (c) select a language, an hour and the currencyand a keyboard or an input method, and then click Next.

  (d) click on check drive for errors.

  (e) in the System Recovery Options dialog box, select the drive of your Windows installation and click Next

  (f) to the System Recovery Options dialog box, click on check Drive for errors.

  (g) use the switch/r to run the disk check.

  Important: Running chkdsk on the drive if bad sectors are found on the disk hard when chkdsk attempts to repair this area if all available on which data may be lost

• Windows could not start the IKE and Authip IPsec keying service modules on the local computer. Error 1075 the dependency service does not exist or has been marked for deletion.

  Hi, I'm trying start the IKE and AUTHOP service from the SERVICES screen but I get this error:

  Windows could not start the IKE and Authip IPsec keying service modules on the local computer.  Error 1075 the dependency service does not exist or has been marked for deletion.

  original title: ike and authip error 1075 the dependency service does not exist or has been marked for deletion

  Hello

  Remember to make changes to the computer before the show?

  You can follow the below methods:

  Method 1: Restart Windows and try to start the Security Center service.

  If you still receive the same error, make sure that the WMI service is launched and running:

  (a) click Start, run , and then type Services.msc

  (b) double-click Windows Management Instrumentation

  (c) set its startup type to Automatic

  (d) click Start to start the service, and then click OK

  (e) restart Windows.

  Method 2: Restart the service

  Windows logs an error if the service IKE and AuthIP IPsec Keying Modules or the driver does not start, or suddenly, they end.

  To restart the IKE and AuthIP IPsec Keying Modules service:

  To perform this procedure, you must have membership in the local Administrators group, or must you have been delegated the appropriate authority.

  (a) restart the service. You can do this from a command prompt or in the snap-snap-in Services Microsoft Management Console (MMC). Do one of the following:

  ·         Start an administrative command prompt. Click Start, click principally made programs, Accessories, right-click guest, and then click run as administrator. At the command prompt, run the command net start ikeext.

  ·         Click Start, type services.msc in the Search box and press ENTER. In the column name of the Services snap-in, right-click on IKE and AuthIP IPsec Keying Modulesand then click Start.

  (b) if the attempt to restart the service fails, restart the computer. This forces all related and dependent services to restart.

  (c) if the error persists after restarting the computer, then the executable files for the driver or service may be damaged, and the operating system must be reinstalled.

  Note:

  You can check that the IKE and AuthIP IPsec Keying Modules (IKEEXT) service runs by using the Component Services Microsoft Management Console (MMC) or the net start command line tool.

  You can check the link: http://technet.microsoft.com/en-us/library/cc733299 (WS.10) .aspx

• Windows could not start. Winload.exe corrupted

  Been having some problems with my Equius has therefore decide to start, F8 and do a system restore toshiba.

  The problem is now I can not even start until now to get the recovery/restore option. I get: -.

  Not sure how it all works, but I guess that recovery stuff are stored on a separate partition. Problem is I guess you must be able to start to load windows before you even get to do this?

  I downloaded and tried a boot with no joy, and of course vista recovery disk, toshiba provide a vista disk. How the hell can I recover from this situation?

  Hello!

  If you are not able to get in the boot menu for HARD drive recovery, you must use a Microsoft Vista disc to reinstall the OS.
  Or you use the Toshiba recovery disc but I think you forgot to burn the disk because normally you get a message (recovery point) you want to burn the disc.

  However, you can order a Toshiba Toshiba recovery disc directly:

  Thanks for looking

  Dean

  > My question is, is - this easy to fix & if not where is the best place to consider to get fixed. Said I was pretty dense

  I think its easy to correct, but you'd need a Toshiba recovery disc.
  Have you created one in the past?

  If not, try to start the HARD drive recovery: turn on the device, press F8. Now choose fix my computer.
  Now new window should open, and here you must select Toshiba HDD recovery option. This would create the laptop back to factory settings.

  In case this isn't possible, you will need to boot from a recovery disk to reinstall the system.

  Hello mtb123,

  1. have you tried the steps suggested by Srinivas R in the previous post to make a startup on your computer repair using the Windows installation disc?

  2. you remember what changes you made to the computer before you start this error?

  I suggest that you access the system recovery options using a Windows Vista installation disc and do a startup repair and if this fails, you can do a restore of the system from the Windows recovery environment.

  You can see the previous post of Srinivas R to verify the information on the system restore.
