• HP ProBook s 4540 - system does not boot after recovery

  My friend gave me the laptop, because the system has not been detected. I decided to recovery operating system.
  I had to face following error messages:

  -I did not receive "Boot Device not Found" error

  I started the HARD drive with result success test

  -next step was to recovery OS
  He finished with the new error message
  "The boot image selected is not authenticated to. "Press to continue.
  According to this topic:
  http://h30434.www3.HP.com/T5/notebook-operating-systems-and-software/selected-boot-image-did-not-aut...
  I did following:
  -secureboot changed to disabled
  problem persisted

  -legacy changed to enabled
  Since then, I'm not able to do anything. When I leave the start system, it ends with the HP logo, and nothing happens.
  When I press ESC after a reboot, menu appears, but I am not able to enter the BIOS. If freezes all the time in the menu with the text highlihted.

  I tried to remove the battery, unplug the power, press the powerbutton for 30 seconds, nothing has changed.

  Next step should probably be to temporarily remove the RTC battery, but I don't know if I'm allowed to open it without losing the warranty.

  The laptop is about 3 months old.

  Hello:

  Because the laptop is under warranty, I suggest your friend contact HP technical support and ask them to solve the problem.

  When you get a not found boot device error it's hard drive (if the test says it is spent or not) or the drive controller on the motherboard.

  I wouldn't touch with a ten foot pole.

  HP support will probably have your friend go through certain stages that you did before they tell him what to do next as return them for warranty repairs, etc.

• System does not boot after changing graphics card

  I'm under VMware ESXi 4.1 on HP xw8400 workstation. He worked well with HP Nvidia Quadro FX1400 graphics card, but after a while I became tired of all that noise and he changed his Asus Nvidia 7300LE. Now the system stucks on vfat successfully loaded.

  If I re - install the system with this another graphics card, it'll work?

  Strange that a simple graphics as blocked change the boot process.

  Maybe you order card PCI is also change.

  Simple, you can reinstall your host and then re-import the VMFS volumes.

  If you have local storage, make sure not to format the existing VMFS partition.

• System does not boot after changing the appearance settings

  I installed XP Home successfully, but the resolution of the screen to be changed. When I followed the instructions of troubleshooting, I was unable to get to the drivers. I changed the settings on the advanced screen prompt to auto, and now after the Windows XP logo load and it I hear the hard drive running, the next screen is completely white/black. Help!

  Is this the same solution for: in the advanced options of monitor, I selected "do not use this device"?  I tried to update the driver for the monitor and reach for straws when the button 'update driver' has been 'grayed out' (not available).  I have a new HP 2009 flat screen and have just installed XP on a new hard drive.  Monitor worked, although some resolution.  The type of monitor has been defined as "default monitor" and driver is VgaSave.  Thank you!

• System does not boot, get the white screen after preparation for auto repair

  Hello

  I have a Toshiba Satellite with Windows 8 and yesterday there were some ongoing update and must restart.  When the computer reboots, it took some time and then I got a blue screen (very quickly) who said something as she encountered a problem and needs to fix (it is really fast and I can't see the whole text).  Then goes and comes back as it is booting (with the toshiba logo) and he says prepare auto repair.  Then it goes to a white screen. I tried to get into the HARD drive recovery (power with F12) and when I select HDD Recovery and confirm Yes, it just goes to a blank screen.  I went into the Setup utility (powering now F2 while) and has chosen default install and who does not either (although it has fixed the problem with my keyboard backlight does not). Support of Toshiba said that it is the operating system, not the hard drive.  But I need a drive recovery media that will scan all.  Anyone know other options?  I have a disc of recovery of a Microsoft coming 8 Pro (dell).  Would it be an option, to use it (I got it on a flash drive) and start-up of that?  Thanks for the help.

  Hi John,.

  Thank you for the update.

  Given that you want to use the Windows 8.1 recovery disk, you won't perhaps able to start Windows 8 using Windows 8.1 because the computer may not be able to find the files of Windows 8 start to recover.

  Yes, you pouvez install 8.1 Windows using the recovery disk. However, you may not be able to perform the upgrade option when installing Windows 8.1. When you click install now and follow the instructions, you must choose the Custom Advanced option to continue installation. Choose Advanced custom options will create a folder in the C: drive (or any other partition when you do not want to install) named the Windows.old folder which expected to have all of your files and documents of previous installation and are accessible.

  Make sure you have the drivers available for the devices installed on the computer as network card, drivers etc. of video card you install Windows 8.1.

  Hope the information is useful. Please feel free to answer in the case where you are facing in the future other problems with Windows.

  Thank you.

• Satellite Pro A200 - system does not boot

  Hello

  wondering if someone could help?
  My Satellite Pro A200 with windows XP does not start. It starts with the Toshiba screen.
  Then goes to a screen black with text where it says "PXEE61 media test failure - check cable" (I have no cable) then said out of PXErom; moves to the next screen, which lists the options: safe mode; safe mode with networking; safe mode with prompt local; Last Configeration well-known; Start windows normally.

  Which have been tried and results in loading from page turns on for about 20 seconds, then just to abandon and trying all the whole process again (before flashing a blue screen) Windows.

  Nothing seems to work - tried to take the battery on a... number oftimes and the power cable, but nothing helps.
  It's already happened, but after a few false starts gets going - but this time he just don't come out it. I could not take others where locally, but I would prefer not to because I live in Spain and need the laptop as soon as possible and do not know, I want to leave it in some otherwise are hands to the risk of wipe them the hard drive.

  So, I would be very grateful for any help as soon as possible and I fear tech short hand maybe having to explain.

  Thanks a lot, a lot.

  Hello

  I think the problem is that the operating system is not found on the HARD drive.

  The test failure PXEE61 media - check the cable appears especially if the laptop tries to boot from LAN.

  Why the laptop is trying to boot from the local network?

  Well,.

  -option may be the LAN was chosen first in the boot order in the BIOS
  -Maybe the drive is defective and so the laptop is trying to boot from LAN
  -the MBR (master boot record) is may be defective

  I think you should take the Toshiba Recovery CD and need to format the HARD drive and needs to be reinstalled the operating system.
  This should help.

  If not, then the HARD drive could malfunction and should be replaced!

• Upgrade CPU, system does not boot, winload.exe "Windows cannot verify the digital signature for this file.

  Subject pretty much said it all.  I got a new CPU, shut down the computer, installed, and now Win7 does not start.  It hangs on a black screen gripe on a signature file.  Here is the full text:

  "A recent hardware or software change might be installed a file that is signed incorrectly or damaged, or maybe it's a malicious software from an unknown source."

  If you have a Windows installation disc, insert the disc and restart your computer.  Click 'Repair your computer' and choose a recovery tool.

  Otherwise, to start Windows, so you can investigate further, press the ENTER key to display the boot menu, press F8 for Advanced Boot Options, select last known good configuration.  If you understand why the digital signature file cannot be verified and want to start Windows without this file, temporarily disable driver signature enforcement.

  File: \Windows\system32\winload.exe

  Status: 0xc0000428

  Info: Windows cannot verify the digital signature for this file. »

  Well, the first thing I did was put in the installation CD and reboot to try the thing "repair your computer".  Charge, said he found a problem, said he has fixed the problem and restarted.  But it always hangs on the same screen of the error.

  So I tried to hit Enter and then F8 as it said to do, but brings me right to the error screen.  I'm stuck, there is nothing that I can do, and I need this computer to work tomorrow.

  Another interesting note is that the recovery on the installation CD tool identifies my system installed Windows Vista... wtf.

  Help?

  I don't know if this post will solve your problem, but it can give you new ideas or angles to try.

• Installing the graphics card... System does not boot

  Hello

  I received a HP P6-2387ea today (I5, 8 gb, H61 Chipset) with the intention to introduce a new GeForce660 inside that also happened today.

  The PC boots up well with its default material and very well with my addition of a 500 watt PSU... However, when I add in the GeForce 660 does not start, I am rather greeted by 6 beeps to the bios, which is obviously not a good thing.

  My first thought was gpu at fault, but I tested it on another machine and it works fine. I also took a GeForce 460 of this old machine and tried in the new HP one, same result.

  I'm missing something here, or I have a faulty card or something?

  (To avoid responses of stupidity, yes the 500w PSU is a lot and the appropriate pci-e 6pins were attached).

  Any help would be appreciated.

  Hello

  First response to your title question is "no, your motherboard is not broken.

  Try this:

  Boot into the bios and go to the Secure --> Secure Boot Configuration topics. Now disable secure boot and turn on legacy mode. Now let's see if the PC will start using the material existing HP before you make any changes. If the PC starts, then try just a video card.

  View your results.  I have a suspicion about what the issue is for the motherboards that are active UEFI.

  --------------------------------------------

  Side note:

  It seems someone is trying to find an answer to this question using different HP computers as a way to find the answer when the PC is delivered W8 and active UEFI.

• [Solved] pc with xp home edition as the operating system does not start after installation of SP2 via automatic updates

  Hello everyone. After formatting my hard drive I reinstalled windows xp edition sp1 family and then installed the latest version of windows update agent. I have the auto update set to download the updates automatically and notify me when they are ready to be installed. Initially, he found 3 updates that I installed and rebooted. He concluded 58 updates. Again, I've installed and restarted. After that, we found ServicePack 2, I installed as well. But after the reboot, the pc does not start. What I get is the windows xp logo which discoloures after a few seconds and I don't see a bar moving from left to right. I left it like that for 3 hours, but nothing has changed. Also, it does not start in safe mode. I get a screen with red and green vertical lines in this case. Anyone know what's the problem? I'd appreciate any help. Thank you.

  I was finally able to solve this problem. That's what I did. I reinstalled windows xp home and followed the same path (but his definition of the automatic updates notify me before downloading or installing updates) until the automatic updates found in the new service pack 2. This time that I did not choose to download it. Instead I downloaded from here http://www.microsoft.com/en-us/download/details.aspx?id=28 and then started in safe mode and installed. I don't know one that makes the difference but service pack 2 has been successfully installed this time and tha pc was able to start after installation. Before that, I also downloaded and installed the latest versions of 2 drivers through drivermax. I mention this in the case where he has also made a difference. After the service pack 2 installation and restart, automatic updates will be found a few others brought up-to-date, but after installation and reboot, it found no others. I had to visit update windows Internet explore and search for updates it and managed to find other updates and finally SP3.

• System does not boot into Windows when a USB is installed

  It's strange.  I just installed Windows 7 Home Premium Upgrade (64-bit) of a previous Vista machine.  Has made the choice of 'Upgrade '.  Now that it is finally installed and get some of the bugs resolved, a question I still have is when a (key, post HD) USB device is installed in the machine and I run a reboot or extinguished/turned on, the system starts to boot, runs through the BIOS section, but just before trying to start Windows I get a fast blinking cursor in the upper left of my screen.  If I remove all the devices usb between PC and manually must shut down and restart it restarts in Windows very well.  What is the problem?

  Desktop HP M9350F model; 64-bit; BIOS Rev 5,29 (28/04/09); BIOS Boot Priority: floppy, CD, HD, network (note: there is no other choice shown/available USB?)

  Maybe someone else has had this problem and an easy fix is avaiable.  Thank you!

  CD,

  Well believe it or not, I realized the problem.  Not the BIOS.

  One program, I have installed is SecureDoc WinMagic.  It's encryption software, although my drive has (yet) been encrypted.  In fact I had contacted the Lim before this same thread started to think it might be because of that, but he told me it was probably my BIOS and nothing to do with their SW.

  However, last night I decided to remove their SW before my "repair" operation was scheduled.  How to have this removed SW, it's just our curiosity, I decided to start once more with a USB device installed to see if the hang up has continued.   By my surprise, the start went as usual by means of windows and office.  DAMN!  all this time lost, mine and yours!

  I contacted the company SW this morning and they found a way to modify their SW and get the boot to work (always with the unencrypted disc).

  I wanted you and someone on this thread to know the outcome, so if this happens in the future with another user, this can help to avoid long-term on unnecessary troubleshooting.

  Thank you once again for all the time you have helped me with this issue!

• System does not boot up... message is... "" peripheral USB on the detected... current situation system turns off after 15 seconds.

  I recently bought a new golf gps device and connected to my desktop pc to register. After unplug his computer m USB cable I can't start my computer.

  whenever I start it the pc his usual routine, but then I saw the following message... USB device to the system detected. System turns off after 15 seconds.l

  Fifteen seconds after the system shuts down. It wiil also not afford to start or access the safe mode, the program installation or any other type of recovery mode, I could access normally. It will also not recognize my Win XP installation disc. I guess it's because of the configuration of the BIOS which accesses the hard drive before the CD rom drive.

  The problem was obviously created by the golf gps USB cable but I can't find a way to get the system to boot so I can find a way to eliminate the problem.

  Thanks for any help that anyone can provide. I am running WinXP Sp3

  Hi PAULARUNNELS,

  ·         What happens when you try to start in the Advanced startup options?

  ·         You receive the same error?

  ·         You external devices connected now?

  Try the following.

  Method 1: Disconnect external devices not essential, connected to the computer and restart the computer.

  Method 2: Load default BIOS (Basic Input\Output System) settings, and then restart the computer. Make sure that you have the CD drive set as first boot device. Check the settings by consulting the manual or call the manufacturer to do so.

  Note: Be careful when you change the BIOS settings. The BIOS interface is designed for advanced users, and it is possible to change a setting that can prevent your computer from starting properly.

  Method 3: If you are unable to start on one of the advanced startup options, and then you can follow this article.

  How do I recover from a corrupted registry that prevents Windows XP startup

• "isass.exe system error indicates an encountered or specified revision number is not one known by the service." System does not boot.

  My roommate has downloaded a manual from LG Electronics cell phone in format .pdf (Adobe). The download is complete on Firefox. It double click on the download finished in the 'Download', its pc box became very slow and finally frozen. It is running Windows XP Media since 2004 / 2005.
  When it tried to reboot, the following message appeared...

  "... isass.exe system error indicates an encountered or specified revision number is not one known by the service." Continues it's maybe a more recent revision, then the service is aware of... »

  Then will continually attempt to restart. by a failure. Note the sequence of the events above are as accurate as the harshness.

  Does this mean the registry is damaged?

  Ran Iolo System Mechanic and has been able to run the tests in two (2). One of the physical drive and the other to the integrity of the partition. Nothing helps. A ran Norton recovery and found no errors. Performed a chkdsk /r and no mistake. Ran a chkdsk/p and found errors, but was not fixed. Any suggestions about where to start?

  I would like to thank all those who helped in my installation of Windows 8 Preview of consumer. He didn't find any problems of incompatibility with Norton a few months back and HP support said that the hard drive has been ruined, and I had to buy one of them after receiving the disks to install Win 7 again. Instead, I have used Drive Scrubber from Iolo System Mechanic and installed Win 7 perfectly. I'm now back with Windows 8. ALL of you are awseome!

• System does not boot: failure of the video card or viruses? I do not know...

  Here's the deal: on a computer running Windows XP Pro SP3. Athlon, dual-core processor (2.4 gHz); 4 GB of memory; NVidia GeForce 7300 video card; and a Western Digital SATA, I met a failure while watching a DVD (using Media Player 11) and now I can't start.

  I have been having problems for a few days with my Dell flat screen monitor "energy saving" mode because it has detected no signal. After playing with this and obliging to recognize a digital signal rather than the automatic detection, all seemed well.

  During the film, the picture froze, the sound became a loud, grating buzz and shut down the system.  It has restarted as usual, but then would not start the rest of the way, stopping at the Windows XP screen.  The progress bar froze and spinning to stop the drive.

  However... on occasion, for example when the system remained some time, I can sometimes start in safe mode (but still, it hangs when starting "mup.sys") or he will move to the XP logon screen and freeze it.  I replaced the mouse and keyboard (whiched USB connections) used with their equivalents of PS/2, but nothing has changed.

  When I try to start, I hear all the clicks Associates, snoring and whatever else as if the startup continues normally.  However, when it stops, I can't "see" it on my network.

  I have a hunch that it is a damaged video card because also the failure during the film and previous issues of monitor, when I hit the map to try to reinstall, he felt much warmer that it should have, but a video card failure would prevent initialize to top?

  Any ideas?  I'm all that.

  It does for me, but of course as I said in my previous notice of Disclaimer: I want to emphasize that you should not take what I wrote as a definitive diagnosis. I can't see or test your computer from here. I give you my opinion on your computer based on my experience as a computer tech and what you have written. MS - MVP - Elephant Boy computers - don't panic!

  I understand that.  I was looking for another opinion by giving an update.

  However, it certainly seems that the jury went.  It freezes even trying to boot in the BIOS setup.  Thanks for the directions.

• System does not boot

  Nothing happens after the diagnosis of start-up game. Screen displays the message "windows did not start correctly last time" and gives options. No work and when the countdown ends at "load windows normally", system freezes.

  The restore disk provided allows only a hard drive formatted and reinstalled but I have all my music, photos and other work, including important emails, on the phone and that you do not have a back upward.

  How can I start windows from a CD so I can remove my docs on an external hard drive before formatting? Help, please!

  Hi Julian,.

  Your easiest option would be to remove the hard drive from your laptop and install it in a USB Caddy which you could then fix it on another PC and copy your data. Could then just reformat/reinstallation of your system using the recovery CD.

  If you have access to a genuine Microsoft installation CD then you could try to boot from that and try to repair your existing operating system but I don't think that you would be able to copy your data using this technique.

  Finally, you could use a bootable CD of one of the utilities of commercial backup/restore (like Norton Ghost or Acronis True Image) and try to unload your data on an external by using this utility.

  Kind regards
