  Hello

  If you do not, use another PC to create a Windows 7 repair CD.  Download the ISO from the link below.

  Windows 7 64 bit

  You must use an app like ImgBurn to burn the ISO to a CD ( Note: you can deselect additional software during installation of ImgBurn options)- hereis a guide on the use of ImgBurn to write an ISO on a disc.

  One time created, or if you already have this, typing away at the esc key when you launch Notepad to open the Start Menu.  Insert the CD to repair.  Select boot options ( f9 ), use the arrow keys to select the CD/DVD drive and press ENTER.  You can also get a prompt to "Press any key to" continuous - it if requested.

  When loading, select repair your computer and choose the command line.  When this charge, enter the following commands and press on enter after everyone – including spaces as shown.

Then I click Next, then I closed this request. Then I restart my computer manually but blocked windows then I wait 5 or 10 minutes, but do not restart Windows. I turn off my APR, then I turn on my pc then windows does not start. I try to reformat but it's the same story that windows does not start. I try to remove the cmos battery hoping it will solve then it works. But the problem is that I insert my bootable cd, it runs automatically even I don't not press a key on the keyboard, the process to continue installing windows, it sounds I can not install my windows correctly. When he restrart the process goes again to load all the drivers everywhere why did this happen? Is there something wrong with my HARD drive once I used YourUninstaller?

  You can create a bootable XP Recovery CD of Console and replace the file, but it may be easier for you to make boot CD of a Hren.

  When you start the Hiren's CD, choose the XP Mode of Mini and it has an interface in XP style Explorer where you can find and replace the winlogon.exe suspicious or missing file.

  There should be a copy of winlogon.exe here:

  c:\Windows\System32\dllcache

  Rename your current c:\windows\system32\winlogon.exe file (if it exists) and copy / paste the replacement of c:\windows\system32\dllcache.  If you do not see here, search your HARD drive and find one.  Another possibility (depending on your environment) is c:\windows\ServicePackFiles\i386, or c:\i386 d:\i386...

  You just need to replace the file winlogon.exe somehow.

  When you are finished replacing, restart as usual (remove the CD bootable of course).

  With the help of Hiren, you can also copy offshore on an external device (USB key or HARD drive), all personal security files.

  Do you have a Hiren BootCD you can download here:

  http://www.hirensbootcd.NET/

  On the left, click on download, scroll down, choose the latest 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 the Hirens.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.

  Using the Mini XP, you can access Internet, maneuvering around your system, search for files, copy files, replace the files and run the scans for malware, edit the text files (like the c:\boot.ini) etc.

  There are dozens of free and useful tools included in the CD that can be used to repair your system or copy your important personal files on another device (like a USB device or an external drive) in the case where you just give up and decide to reinstall your XP (I hope that you will not make this decision).

  Do, or do not. There is no test.

• help my pc does not start the only way is in safe mode

  I tried to restart but nothing works I don't know what to do and I have no recovery disk.

  Restore point:

  Try typing F8 at startup and in the list of Boot selections, select Mode safe using ARROW top to go there > and then press ENTER.

  Try a restore of the system once, to choose a Restore Point prior to your problem...

  Click Start > programs > Accessories > system tools > system restore > choose another time > next > etc.

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

   

  If restore work not and you do not have a Vista DVD from Microsoft, do a repair disc to do a Startup Repair:

  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.

  When you have changed that, insert the Bootable disk you did in the drive and reboot.

  http://www.bleepingcomputer.com/tutorials/tutorial148.html

  Link above shows what the process looks like and a manual, it load the repair options.

  NeoSmart containing the content of the Windows Vista DVD 'Recovery Centre', as we refer to him. It cannot be used to install or reinstall Windows Vista, and is just a Windows PE interface to recovering your PC. Technically, we could re-create this installation with downloadable media media freely from Microsoft (namely the Microsoft WAIK, several gigabyte download); but it is pretty darn decent of Microsoft to present Windows users who might not be able to create such a thing on their own.

  Read all the info on the website on how to create and use it.

  http://NeoSmart.net/blog/2008/Windows-Vista-recovery-disc-download/

  ISO Burner: http://www.snapfiles.com/get/active-isoburner.html

  It's a very good Vista startup repair disk.

  You can do a system restart tool, system, etc it restore.

  It is NOT a disc of resettlement.

  And the 32-bit is what normally comes on a computer, unless 64-bit.

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

  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.

  Ask them if you can also make recovery disk/s for the recovery Partition in case of a system Crash or hard drive failure.

  They will tell you how to do this.

  Every computer manufacturer has their own way of making recovery disk/s.

  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.

  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

• Help! VM does not start successfully after the conversion of Server VMware ESXi 4.1

  Hi, I have install my first server ESXi, everything seems OK and stable. Had a few PtoV machines, but to start I thought I propose our only current VM from VMWare server on our ESXi server.

  The VMware host is Win2003/32 running VMware server 1.0.6 and the prompt is also Win2003/32. I shut down the VM, installed the stand-alone converter on the VMware host and let it do it's thing. Successfully completed and took 20 minutes.

  When I try to start the virtual machine of the ESXi server, it looks OK, but hangs on "Application Startup Scripts", possibly the login screen appears, but then I get messages from "Remote RPC server not available" when you try to open an RDP session. A local login hangs right on the application of personal settings.

  Network everything seems fine, can ping the VM, etc.

  May not work on why the virtual machine should start any differently? Any ideas, anyone please. I am new to ESXi and migrate the virtual computer, but have used VMware Server a lot in the past.

  All advice appreciated...!

  That's good news.

  Which explains, normally, you must do the VMTools upgrade, then the virtual machine hardware, so if the converter upgrades the equipment, the order is bad. Of course, it is recommended to upgrade the hardware to ver 7. So now that it works you can improve the tools and then the vHardware. It might be interesting, if you have enough resources on the ESXi host, make a clone to the virtual machine and the test on the clone in a State (disconnect vNIC) offline.

  Please allow Points if it is useful

• Help, VMWare Fusion does not start

  Hello world

  The night last VMWare fusion stop Windows XP on it is.  I use Mac OS X.  Now, the screen is black. I can not shut down or restart the virtual machine. It only allows me to suspend.  I have already stopped my mac once and restarted. When I restarted VMWare the screen remains black.  I found the following on the support page suggesting. I can understand how everythign except 'launch of Fusion parameters.  I'm afraid to try this to spoil things. I have attached a few newspapers. I was looking on the forum and it seems that a few people have asked this problem, but I didn't know what to do by reading the discussions.  Any thoughts? Fixed certain log files.

  Thank you very much!

  Windows XP or 2000 virtual machine stops responding during startup Impossible to restart or shut down the virtual machine Windows XP or 2000 virtual machine can only be suspended
  Solution

  |

  |

  You are able to stop the Windows XP or 2000 virtual machine:

  < / div >

  1. Click the Virtual Machine in VMware Fusion menu.

  2. Choose Shut Down Guest list and launch the Parameters of Fusion.

  # Check if the there is no anomaly.
  
  

  If the problem persists, remove Fusion suspend file.

  
  

  
  

  
  

  To remove Fusion suspend files:

  < / div >

  1. Stop VMware Fusion

  2. Search for and locate your Windows XP virtual machine. The default VM location is users / & lt; username & gt; / Documents/Virtual Machines .

  3. Click the Pack Windows of the virtual machine and choose Show Package Contents.

• Delete suspends .vmss and .vmem of the directory of the virtual machine files.

• Remove the lock files or records (.lck or . WriteLock) from the directory of the virtual machine.

• Open the .vmx file using a text editor.

# Delete the following entry in the .vmx file:

checkpoint.vmState = "& lt; virtual_machine_name & gt;. VMS.





# Save your changes. < / div >

|

To be on the right side read a bit about where to find things of A Beginner's Guide to VMware Fusion

Once you find your current VM (this is what I meant by VM topic), then you can either copy & paste as you suggest, or drag another hard drive (if you have several available) and it will copy.  From my experience, it takes about 1 GB / minute to copy between 2 Firewire 400 external drives, then the copy may take some time depending on the size of the virtual machine is.

It's probably a good sign that Shut Down Guest is active, then force power off can back you on track.

By chance, you had just upgraded merger, or have you tried to upgrade VMware Tools when this started to happen?  At the end of the log, it seemed that tools attempted an update, and I wonder if you are stuck in some kind of loop when trying to manage this.

Backup and try the power first, I hope that you will get underway again.

• 2006 iMac does not start. Help restore

  I have an Intel iMac core duo with iSight and built in disk drive around 2006. It does not start.

  When I turn on, it sounds and passes to the gray screen with the apple logo and a progress bar or a spinning wheel. Then he stops down. I tried all the troubleshooting and nothing works. In addition, I don't have the disks that originally from cane with the computer. So I can't make a diagnosis of the hardware. (Unless someone is willing to sell me their album hehe).

  This problem happened to me in 2012. I had a friend restore the computer to empty the hard disk, then boot from the snow leopard disc and reinstall everything. It worked like a charm.

  In 2013, a disc is stuck in the drive. I have troubleshooted only and nothing has worked. I assumed that the drive is dead and has continued to use the computer without worrying about that. Then, in 2014 someday when I restarted, the disk jumped! I never tested the drive then because I was afraid of another stuck disc. Then, the computer is dead again as he did in 2012.

  SO I know what to do. I need to wipe the hard drive and start over. However, I didn't have a drive. So, I bought one on eBay. When I insert it, the computer enters the disc. I can hear the mechanics works. It ejects even properly. However, I can't boot from the drive. When I start the iMac by pressing option, I don't see the Macintosh, no disk drive.

  My hard drive died? If so, a USB dvd drive would work? If USB does not work, how can I replace the drive?

  Is it possible that I bought a drive bad or fake software and that's why I can't boot from the dad?

  Please help in some way!

• MacBook does not start without warning, please help I'm losing my mind

  MacBook pro froze performs a simple operation. Got the wheel turns and could not enter the finder, etc. Did a hard reboot. Now the computer does not start. I get the apple journal and the bar for a minute or two and then a zero symbol IE forbidden - a circle with a line through it.

  Surprisingly, it is less than two months after a similar disaster where the computer would not suddenly start. In this case, I was able to get repaired the program apple logic board (the problem was compatible with the congenital fail GPU result).

  Incredibly this time the macbook seems to be in even worse shape. I don't get anything useful from the startup keys.

  cmd R - take me in a gray screen no symbol

  D - no symbol grey screen

  option D - it took a while but eventually I got to choose the network, then it seemed to freeze on the globe

  option - strangely this brings me to a screen asking me to choose the wireless network, but it does not all networks in the box. weird - this happens even with a simple bootable usb key

  option cmd R - annoys me to the world, but the world does not revolve

  T - puts me the screen of the target disk, but the disk is unreadable from another computer

  cmd S / cmd V - gives me a code screen and then freezes

  Shift - takes me to zero cross again

  C - think for awhile, but let me on an undefined gray screen

  (I need some advice on the start-up of the thumb. Pressing C should force the startup of the thumb. I did an inch bootable with el capitan. However, I am not convinced that my thumb works on a functional mac either - I just can't get a macbook functional 2009 to start the boost by pressing C, although it starts from the thumb if I press option and go through the menu. Weird.)

  Help, please. Urgent need to use the computer and access the data on it.
