  Hello

  XP disk will not help you to fix Vista

  As the system restore does not try a startup repair and / or a restoration of the system using a Microsoft Vista DVD

  Manufacturers recovery disks normally do not have Service Options; they are normally a relocation to the factory only settings option.

  Here is the guide to repair Options using a Vista DVD from Microsoft.

  If a friend or a work acquantance of yours has one, you can borrow and use it for repairs.

  Table of contents

  1. Overview of Windows Vista repair options
  2. How to perform an automatic repair of Windows Vista using Startup Repair
  3. Advanced Tools Overview
  4. Conclusion

  If you do not or can not borrow a Microsoft DVD there is a download of a file ISO of Vista Startup Repair available that you can put on a Bootable floppy to make the above startup repair and that the method is recommended by a large number of posters in these Forums.

  Unfortunately, you have to buy it.

  Here is a link to it:

  http://NeoSmart.net/blog/2011/Windows-Recovery-discs-updated-reinstated/

  @@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@

  And here are a few ways to reinstall Vista.

  There is no Windows Vista downloads available from Microsoft.

  You can contact your computer manufacturer and ask them to send you a set of recovery disks.

  They should do this for a small fee.

  And if you have never received a recovery disk when you bought your computer, there should be a recovery Partition on the hard drive to reinstall Vista on how you purchased your computer.

  The recovery process can be started by pressing a particular combination of the key or keys at startup. (Power on / start)

  Maybe it's F10, F11, Alt + F10, etc., depending on the manufacturer.

  Ask them to the proper key sequence.

  You can also borrow and use a Microsoft Vista DVD, which contains the files for the different editions of Vista (Home Basic, Home Premium, Business and Ultimate) must be installed. The product key on your computer / Laptop box determines what Edition is installed.

  Other manufacturers recovery DVDs are should not be used for this purpose.

  And you need to know the version of 'bit' for Vista, as 32-bit and 64-bit editions come on different DVDs

  Here's how to do a clean install of Vista using a DVD of Vista from Microsoft:

  "How to do a clean install and configure with a full Version of Vista '

  http://www.Vistax64.com/tutorials/117366-clean-install-full-version-Vista.html

  And once the operating system is installed, go to your computer manufacturer's website and get the latest drivers for your particular model or laptop computer.

  And phone Activation may be necessary when you use the above installation method.

• Blue screen - ntoskrnl.exe was able to start: kernel missing/corrupted dxgkrnl.sys

  original title: BSOD and freezes, several errors reported, puzzled.

  Hello

  I've been struggling with trying to understand an intermittent problem for the last 3 weeks.  The problem has been around for one more month, but it seems to happen more and more often can't find the source.  I wish I could attach the dump files memory here, but don't see any option for this.  So here it goes...

  Have had this computer for 2-3 years and have not changed the material at all and only the drivers updated.

  CPU: Intel Core i7 CPU * address email is removed from the privacy *.

  Motherboard: ACPI x 64

  PowerSource: Power TX 750W.

  2 Hardrives: WDC - WD6401AALS-00L3B2 ATA

  6 GB OF RAM

  Graphics card: NVIDIA GeForce GTX 260

  I have wiped the two HD, reinstalled Vista.  I've updated the Vista completely.  I've updated the following drivers to their latest: graphics card, motherboard, map its (motherboard), LAN (motherboard).

  The computer crashes more often that the BSOD appears.  When it freezes, the sound plays all that was the last one on again and again and nothing does.  No data memory is dumped to the crash.  I checked with another computer that is on the network to see if she could still access shared files and that he could not.  It has frozen or gave the BSOD when just doing electronic-mail/surf net or playing dungeons and Online (DDO dragons).

  Challenges in a relationship with install/updates: SP2 would not install through normal updating, so a download and install manually.  DDO requires NET framework 1.1 to run.  Had to integrate the installation so that it can install.  Do not remember having to do in the past.  The point of freezing/BSOD is always the same before and after I did the complete wipe.

  Made the following stress tests:

  Don't use memtest 86 + (2.11 and version 4.10) x no errors, 8 longer past track.

  Used Furmark 1.8.2 V max stress test, ran all night without crashing.

  Used Video Card Stability Test (Group in stone), no problem.

  Used Seagate Diagnostics on HD, long and short no trials, no failure.

  Reported on BSOD errors:

  Ntoskrnl.exe could not start: missing/corrupted core

  dxgkrnl.sys

  driver_IRQL_NOT_LESS_OR_EQUAL nvlddmkm.sys

  More information on these if necessary.

  I get about 5 freezes with no info to each BSOD with info.  Very hard to debug with any info.

  I've had freezes/BSOD occur minutes after the computer starts and the hours.  Have the box to open with an external fan blowing into the case.  Don't think overheating is the problem.  No overclocking ever carried out on the system.

  I'm relearning all debugging stuff, did not have to do this in a long time any help would be very appreciated.

  Thanks in advance for your help.

  Hello

  If you do not remove ANY power and reconnect the cables (at both ends, memory and cards)
  When possible) - in fact, remove and replace - do not just tight.

  As you re-installed Vista twice the question must be something that works with a low level
  as the BIOS, chipset of low level drivers or hardware.

  You can validate files minidumps on the SkyDrive or other file sharing sites so that they can be
  downloaded, and we will have a look. But to be honest they will reveal probably material
  or worth nothing useful, so.

  Use SkyDrive download collected files and after shot/screenshot.

• 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 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.

  Started and started to format the drive. All of a sudden he projected blue.

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

  cause...

  missing or damaged.

  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:

  You can disable hibernation if it is enabled and you do not...

  When you Hibernate your computer, Windows saves the contents of the system memory in the hiberfil.sys file. As a result, the size of the hiberfil.sys file will always be equal to the amount of physical memory in your system. If you don't use the Hibernate feature and want to reclaim the space used by Windows for the hiberfil.sys file, perform the following steps:

  -Start the Control Panel Power Options applet (go to start, settings, Control Panel, and then click Power Options).
  -Select the Hibernate tab, uncheck "Activate the hibernation", and then click OK. Although you might think otherwise, selecting never under "Hibernate" option on the power management tab does not delete the hiberfil.sys file.
  -Windows remove the "Hibernate" option on the power management tab and delete the hiberfil.sys file.

  You can control the amount of space your system restore can use...

  1. Click Start, right click my computer and then click Properties.
  2. click on the System Restore tab.
  3. highlight one of your readers (or C: If you only) and click on the button "settings".
  4 change the percentage of disk space you want to allow... I suggest moving the slider until you have about 1 GB (1024 MB or close to that...)
  5. click on OK. Then click OK again.

  You can control the amount of space used may or may not temporary Internet files...

  Empty the temporary Internet files and reduce the size, that it stores a size between 64 MB and 128 MB...

  -Open a copy of Microsoft Internet Explorer.
  -Select TOOLS - Internet Options.
  -On the general tab in the section 'Temporary Internet files', follow these steps:
  -Click on 'Delete the Cookies' (click OK)
  -Click on "Settings" and change the "amount of disk space to use: ' something between 64 MB and 128 MB. (There may be many more now.)
  -Click OK.
  -Click on 'Delete files', then select "Delete all offline content" (the box), and then click OK. (If you had a LOT, it can take 2 to 10 minutes or more).
  -Once it's done, click OK, close Internet Explorer, open Internet Explorer.

  You can use an application that scans your system for the log files and temporary files and use it to get rid of those who:
