Re: Satellite U400: operating system not found then the installation of the OS

I have a toshiba satellite u400 with is come with VISTA.

Because I don't like VISTA, I then installed WINDOWS XP with a multi boot.

Everything worked well. But one day I want to resize my partitions I used Paragon partition manager.
This product is required to operate only to resize my xp partition, so he asks me a start.

And then nothing works.

I try to fix my problem with a fresh install, but it seems that the boot sector was not correct.
Then I completely format my hard disk on another computer with a USB CABLE.

When I try to install VISTA, XP or LINUX on a CD or DVD, I ask the multiboot with F12
I chose to boot from the CD/DVD built-in, but I get only "OPERATING SYSTEM NOT FOUND',

It's as if the BIOS test the HARD to FIND something specific, and it does not find.
When my PC worked correctly I could boot from the drive to dvd without problem.

I called the SUPPORT CENTER of about 10 days, but I have no answer.

So if someone could help me.

Thank you.

Hello

OPERATING SYSTEM NOT FOUND message appears generally if the laptop has attempted to boot from the HARD drive and didn t find the operating system.

But I put t understand why you formatted the HARD drive using the USB cable?

Please insert HARD drive in the Bay of laptops HARD drive and check if the HARD drive is recognized in the BIOS!
If the HARD drive has been recognised so I recommend you to take a disk Win XP Home and at the start of this disc.

As I m not wrong not you will need to first install the SATA drivers to recognize the HARD drive.
The fact is that the laptop supports the SATA controller and SATA drivers are needed to get the HARD drive recognized by Win XP.

Well, after you have booted from the Win XP disc you need to format the new HDD by using the NTFS file format and should then follow with the installation of the OS.

    Hello

    I guess that something with your HARD drive is not really OK. An error message is displayed when the system is unable to boot from the CD/DVD-ROM or HARD disk.

    You have to imagine a sequence (called 'boot-sequence') where all devices that are bootable (such as disk, floppy, CD-ROM, NETWORK drive) are "checked" if some boot media or the program is present. Sequentially, the BIOS attempts to load the next available boot media.

    In the case of no current boot media, the system tries to finally boot from the network that doesn't work not because you´re not connected to a corporate network that has sometimes things network bootable... :)

    So, I suggest you to first check your BIOS (by pressing ESC, then F2) and check the "Boot sequence" if something has changed. Check if the HARD drive is located on the first entry, otherwise set it up. If so, then send your machine a partner / reseller/service because your machine then has a really serious problem.

    Help, please

    Kind regards... MB

    I belive that your boot order is not preparing to your boot from the CD/DVD option.

    In the setting VM Edit tab there is an option to go to the bios directly before trying to start. box to check that option and power on the virtual machine, it will go to the bios now set your first boot on CD/DVD device and apply to restart this will make the option set. Now your virtual machine starts automatically from CD/DVD.

    Because this will not your VM to power & power on it will continue after your start option setting is applied.

    You can try it once this option helped me...

    It restarts perfectly okay after good - load in the windows, etc. When he cut - it comes up with a black screen with a bar at the bottom that looks like a bar code.
    In any case today he cut while I was on the internet download music of a secure on my external hard drive - Web site he started back, but this time he remained on the black screen and then tells me it couldn't find t operating system. I turned it off after a while using power button - lit and bingo-test - loaded in windows and was all happy again! How long for? Who knows!

    Asif_Ahmed_Joy

    Hello;

    Let me welcome you on the HP forums!

    I read your post about the operating system not found since the Win10 Upgrade failed and tried to help.

    One of the things that happened during the upgrade:

    (1) it mostly completed but failed in the writing of the new boot loader files

    (2) it failed early in the upgrade, screw up your PC as well

    Allows to process 1) first - by recreating the bootloader files.

    You need access to a PC for this phase of work in order to create the necessary support to fix your PC boot loader.

    Once you have that, please download and create the Win10 installation media from this link: http://windows.microsoft.com/en-us/windows-10/media-creation-tool-install?ocid=ms_wol_win10

    Note that when you download and build install media, the default tool corresponding to what is already installed on your PC (as in home for the House, and 64-bit to 64 - bit).  While you CAN change these settings, are NOT. If you do, the media that results will be different and will force you to enter a NEW product code.

    Boot from the media that you have created and follow the instructions in this link: http://www.tenforums.com/tutorials/2294-advanced-startup-options-boot-windows-10-a.html

    You will need to go to the Advanced Options screen and click on startup repair.  You will probably need to run Startup Repair three times for him to fix all the boot loader.

    Once completed, your PC should start OK.

    If this does not work, then we are on option 2) - which is not good news.

    While Microsoft says there is no risk in the upgrade of Win10, because they allow you to believe that you can always return to your BONES and the original installation program within 30 days, the ugly fact of the matter is that the Win10 GoBack feature turned out to be unreliable - and when she fails, she can let machines in a State corrupted - that does not always happen , but it happens often enough to be a problem and you will get no warning beforehand that he goes to the trash your PC!

    If this is not enough, the Win10 upgrade is known, in some cases, corrupt partition recovery stored by the OEM that built the original machine.  It's pretty much guarantee that no HP recovery will work.

    What will work restores your computer to its original factory state using HP recovery media.

    It is a set of DVD and a CD or a USB key, which will erase the hard drive (removing all data, applications and settings, reinstall the original OS, drivers and utilities for HP. In some cases, you will be able to order a USB instead of discs.  You must order at HP; they cannot be downloaded.

    You can look online for recovery from the paged media related: http://support.hp.com/us-en/drivers

    Once there, enter your product name or number. On your software page and download the drivers, select your operating system and version. Click on "Update".  If the HP recovery support is available for your computer, down near the bottom of the page, you will see an entry for the command Recovery Media-CD/DVD/USB. Click on the symbol '+' to expand this entty and click on order to press for more details.

    Hi Gary,.

    Welcome to the Microsoft Community and thanks for posting the question.

    According to the description, you have problems with the computer not start.

    This problem can occur because of a hardware problem.

    Proceed as from the link below and check if that helps.

    "Operating system not found" or the "Missing operating system" error message when you start your Windows XP-based computer

    Warning: Be careful when you change the settings of the BIOS (Basic Input Output System). The BIOS interface is designed for advanced users, and it is possible to change a setting that can prevent your computer from starting properly. BIOS update should be made only if necessary (to solve a compatibility problem, for example). It can be a complicated process, and if an error occurs, your computer could be rendered inoperative. Be sure to observe the instructions of the manufacturer.

    Meet us if you face problems with computer not start or any other issue of Windows, and we would be happy to help you.

    Good day!

  • Satellite C660 - 10 d Operating System not found PXE - E61: Media test failure

    I have a Satellite C660 - 10 d, which is part of the 1 year warranty which has suddenly decided it won't start and makes a strange noise that sounds mechanical.

    I tried the options F2 & F11 at startup, but I always return to the same messages some options I try:

    Realtek PCIe FE Family Controller v1.23 (28/07/10)
    PXE - E61: Media test failure, check cable of
    PXE - M0F: Exit PXE ROM
    Operating system not found.

    I can't go beyond that and get the laptop doesn't work, which leads to my second problem.

    It is under warranty so I thought I would sign in for repair. The serial number is recognized in the section Product Support My. But when I try to enter in the repair section, it is said

    ERROR: serial not valid number.
    Please check and try again.
    Then gives a number to call which only works weekdays.

    So, I have what appears to be a broken laptop that I can currently connect to repair.
    If you are able to help with one of these problems, it would be greatly appreciated.

    Hello

    I'm quite sure that the problem is related to the defective HARD drive.
    This would also explain the mechanical noise when starting.

    PXE - E61: Media test failure appears as the laptop attempts to boot from LAN.
    Why? Because the disk HARD could not be found and the CD/DVD drive does not contain a startup disk.

    So the BIOS switched to LAN

    This is why replacement of HARD drive should help you with this problem.
    If the warranty is valid, get in touch with a local ASP in your country. Maybe you could get a HARD disk which could be replaced easily

    Hello;

    Let me welcome you on the HP forums!

    According to the page of the product HP for your PC, it came not with preinstalled Win10.  THIS means that you have done the upgrade to Win10.

    While Microsoft says there is no risk in the upgrade of Win10, because they allow you to believe that you can always return to your BONES and the original installation program within 30 days, the ugly fact of the matter is that the Win10 GoBack feature turned out to be unreliable - and when she fails, she can let machines in a State corrupted - that does not always happen , but it happens often enough to be a problem and you will get no warning beforehand that he goes to the trash your PC!

    If this is not enough, the Win10 upgrade is known, in some cases, corrupt partition recovery stored by the OEM that built the original machine. It's pretty much guarantee that no HP recovery will work.

    The problem you mentioned is usually due to one of two basic problems:
    (1) defective hard drive
    (2) damaged/missing bootloader files

    As to the first, please follow the instructions in this link to test your hard drive: http://support.hp.com/us-en/document/c00439024

    If that confirms that your drive has failed, then you will need to replace it.  Please report back if this is the case.

    As for the second, you need access to a PC for this phase of work in order to create the necessary support to fix your PC boot loader.

    Once you have that, please download and create the Win10 installation media from this link: http://windows.microsoft.com/en-us/windows-10/media-creation-tool-install?ocid=ms_wol_win10

    Note that when you download and build install media, the default tool corresponding to what is already installed on your PC (as in home for the House, and 64-bit to 64 - bit).  While you CAN change these settings, are NOT. If you do, the media that results will be different and will force you to enter a NEW product code.

    Boot from the media that you have created and follow the instructions in this link: http://www.tenforums.com/tutorials/2294-advanced-startup-options-boot-windows-10-a.html

    You will need to go to the Advanced Options screen and click on startup repair.  You will probably need to run Startup Repair three times for him to fix all the boot loader.

    Once completed, your PC should start OK.

  • Operating system not found on Equium - PXE - E61:Media test failed

    Hi all

    My daughter has a computer satellite laptop running XP.
    However, the system does not start and the following messages:

    PXE - test failed - check the cable for E61:Media
    PXE - M0F: output of the PXE Rom
    Operating system not found

    We do not have a disk operating system.

    What is the problem and how can I do for her?

    Hello

    For me, it seems that the HARD drive is dead and the laptop can not find the installed operating system.
    In this case, he tried to boot from different sources and finally LAN.
    But it does not and therefore, you get the PXE - E61:Media test failure error message.

    In my opinion, the HARD disk needs to be replaced and the operating system must be installed again.

    See you soon
