• Windows XP does not start. Can I boot Windows from a disk so that I can recover the data?

  Windows XP does not start. Can I boot Windows from a disk so that I can recover the data? This should be a CD because it doesn't have a floppy disk on my laptop drive. It is maybe that my hard drive has begun to fail and therefore cannot locate XP startup files. I can not start using one of the other methods of starting for example. Safe mode. If I can recover the data, I can then reload Windows and check the surface of the disc etc etc. Thank you all for your comments. Steve

  Lately, I'm leaning toward the Hiren's BootCD you can download here:

  http://www.hirensbootcd.NET/

  On the left, click on download, scroll down, choose the most recent version

  The download link is a little hard to see.  It is at the bottom of the page, above the drop for older versions and looks like this (click this component to download the ZIP file):

  Direct HTTP mirror + Torrent, Torrent Magnet

  Click the "Live HTTP Mirror" link to start the download and save the ZIP file on your desktop of somewhere that you can remember.

  The ZIP file is large, so the download will take probably some time to complete.  Then unzip the download to extract theHirens.BootCD.ISO file that will be used to create your new bootable CD.

  Create a bootable CD. ISO file is not the same as simply copying the. File ISO onto a blank CD.  You must use software that includes how to burn a. ISO to a CD to create a bootable CD.

  File ZIP the Hiren is the file BurnToCD.cmd that you can double-click to launch it.  The BurnToCD.cmd will use the file BurnCDCC.exe to burn the. ISO file onto a blank CD using your existing CD burner.  You can also use your own burning software as long as your software is able to create a bootable CD. ISO file.  More modern burning programs can create a bootable CD. ISO image.  Create a CD from an ISO image bootable is not the same as just the file on a CD burning.

  If you need a simple and CD burning, this is a free software popular software:

  http://www.ImgBurn.com/

  Here are some instructions for ImgBurn:

  http://Forum.ImgBurn.com/index.php?showtopic=61

  It would be a good idea to test your new bootable CD on a computer running.

  You may need to adjust the computer BIOS settings to use the CD-ROM drive as the first device to boot instead of the hard drive.
  These adjustments are made before Windows tries to load.  If you miss it, you will need to restart the system again.

  When starting on the Hiren's CD, you will see a menu of options.  Choose Mini XP.

  It will appear while Windows is loading and you will be presented with a desktop computer that has the look and feel of the interface of Windows Explorer, you are already accustomed to using.  You will feel at home.

  Using the Mini XP, you can access the Internet, maneuver around your system, copy files, replace the files, run the scans for malware, etc.  There are dozens of free and useful tools included in the CD that can be used to repair your system, or copy files to another device such as a USB device or an external drive if drop in trying to repair your system.

  If you want to see if you can fix your system, describe what is happening when you try to start and to answer these questions:

  What is your system brand and model?

  What is your Version of XP and the Service Pack?

  Describe your current antivirus and software anti malware situation: McAfee, Norton, Spybot, AVG, Avira!, Defender, ZoneAlarm, PC Tools, MSE, Comodo, etc..

  You have a true bootable XP installation CD (it is not the same as any recovery CD provided with your system)?

• Windows Vista does not start upward, with success since the closure complete

  Hello world

  I actually had this problem for a long time, but I'm just now to a point where I'm ready to take a lead in fixing it.

  I can't identify when it started, but Windows Vista does not start upward, with success of a full stop. He gets to the screen where, in general, the green bars will travel across the screen, but the green bars will not come. The screen looks dim and sits there, with the text of the copyright of Microsoft Corporation. So, after not having on the mound, I have to manually shut down the computer by holding down the power button. When I try to start again, told me to go through the Startup Repair tool. If I jump the repair, I just have to meet the same problem - a computer that will not go beyond the screen "green bar".

  So, I do the Startup Repair, and told me what I do for the restoration of the system. Windows starts normally after the restoration.

  Don't forget, this happens from a full stop. To remedy this, I just never completely shut down my computer. I left running and back just at the beginning of the day. The computer may start restart, it just may not start with a full stop.

  Given the start of repair takes, literally, around 4 or 5 hours of full stops complete, accidental or power outages are a nightmare, I am obliged to wait 5 hours to get access to the computer. Fortunately, I have my laptop.

  If someone has encountered this? I saw people talking about the loop of startup repair, but that's not the point, I have. I have yet to see any discussion of my specific problem.

  Thanks in advance!

  Download the ISO on the link provided and make a record of repair time it starts.

  Go to your Bios/Setup, or the Boot Menu at startup and change the Boot order to make the DVD/CD drive 1st in the boot order, then reboot with the disk in the drive.

  At the startup/power on you should see at the bottom of the screen either F2 or DELETE, go to Setup/Bios or F12 for the Boot Menu.

  How to get Vista recovery Media and/or to use the Vista recovery Partition on your computer.

  There is no Vista free download legal available.

  Contact your computer manufacturer and ask them to send a recovery disk/s Vista set.

  Normally, they do this for a cost of $ small.

  ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

  In addition, ask them if you have a recovery Partition on your computer/laptop to restore it to factory settings.

  See if a manual provided with the computer or go to the manufacturer's website, email or you can call for information on how to make a recovery.

  Normally, you have to press F10 or F11 at startup to start the recovery process...

  Another way I've seen on some models is press F8 and go to a list of startup options, and launch a recovery of standards of plant with it, by selecting the repair option.

  ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

  Or borrow a good Microsoft Vista DVD (not Dell, HP, etc).
  A good Vista DVD contains all versions of Vista.
  The product key determines which version of Vista is installed.

  There are 2 disks of Vista: one for 32-bit operating system, and one for 64-bit operating system.

  If install a cleaning is required with a good DVD of Vista (not HP, Dell recovery disks):

  Go to your Bios/Setup, or the Boot Menu at startup and change the Boot order to make the DVD/CD drive 1st in the boot order, then reboot with the disk in the drive.
