Windows XP cannot find NTLDR on PC Windows XP-Win7 dual-boot

I have a PC that has been working fine until yesterday.  I booted into Win7... and he locked himself more tight as a drum... has not identified ctrl-alt-del, esc or a right click on the start bar.  The only option was to make a difficult stop holding down the power button.

When I got to the top, it has not begun, but said instead he was missing NTLDR, or that he was corrupt.  I broke the Win7 DVD and used to start the PC and went in service options.  I tried the start up to fix... without success. I tried a few other options in the menu with the success.  I finally said to restore to an earlier date using a backup.  Well well... I want in the side Win7... but until now I have been always failed to him start upward on the side XP.

When I boot in Win7 (this is the C: drive, and XP becomes drive D :), I can see the XP partition on drive D: files.)  In research the D: drive, there was the No. NTLDR file on the drive.  So, I jumped into the XP Pro CD and copied the file NTLDR on D:\ i386 folder.  When I did, he said that it was already there (I have my folder options configured to display hidden system files), even if she was nowhere to be seen.  I said to replace the current one with the one I copied... and he appeared at the root of D.  NTDETECT.com was also not appearing in D:\, so I copied that from the i386 to D:\ record.  Yet once, although I couldn't find NTDETECT.com via D:\ research, when I went to copy NTDETECT.com on D:\ he asked me if I wanted to replace the existing copy.  I said yes, and NTDETECT.com then appeared at the root of D.  The boot.ini file was also missing.  I found a backup of this file in the Windows\pss folder.  Similarly, if there is no such file to D:\, when I said to copy the file to D:\ he asked me if I wanted to replace the existing copy.  I said yes.  I now have what should be the good copies of NTLDR, NTDETECT.com, and Boot.ini in the root of D.  However, I still cannot start XP... it says NTLDR is missing or corrupt.

In my online research, an article said that I should have a copy of NTLDR, NTDETECT.com, and Boot.ini on the Win7 partition so she would recognize WinXP... but even once, it does not either... I always get the error NTLDR missing/corrupted when I select Windows XP on startup.

Someone has an idea how I can fix this so I can get to my XP partition?  Oh... and another anomaly... When I use the Win7 DVD to access the 'repair' process, he sees that the Win7 operating system... it does not see the Windows XP operating system.  Is it the way it is supposed to work?  Is it only supposed to see just the OS to Win7 on its partition and don't see any other operating systems on other partitions?

Sorry to hear about your problem, but how it relates to Windows Update features?

What suite of application or security anti-virus is installed on the Win7 partition and is your current subscription?  What anti-spyware (other than Defender) applications?  What third-party firewall (if applicable)?

What application or anti-virus security suite is installed on the Windows XP partition and is your current subscription?  What anti-spyware (other than Defender) applications?  What third-party firewall (if applicable)?

A (another) Norton or McAfee application has already been installed on the computer (for example, a free trial version which is preinstalled when you bought it)?

    Download and run the Microsoft Genuine Advantage Diagnostic Tool:
    Download the tool: http://go.microsoft.com/fwlink/?linkid=56062
    Post your results (copy button) and paste the results in your answer.

    As a starting point, the first thing you should check is the section to three figures on the number of product ID, if it corresponds or is included in one or two digits of the examples below, you have probably a MSDN or TechNet product key. "These keys must not be sold for retail use.

    065 066 067, 068, 069 to Ultimate, box 220 for professional and 230, 231, 232 area for Home Premium,

    There are probably others, but they should be close to those that are displayed"
    (How to be certain - download the Microsoft Genuine Advantage Diagnostic Tool listed above).

    Note: Though that illegally sold MSDN/TechNet allow product key for activation of more than one
    (usually 5 or 10), so these keys can be sold "several times" before activation may fail.

  • Removal of partition of Windows 7 from Dual Boot Windows 7/8

    I recently installed Windows 8 on PC from a parent, because it's the upgrade $ 14.99, uncertain about whether my parents would be as W8, I decided to double it start alongside W7.  However, my parent loved W8 and he now uses as its main operating system.  My problem is, how safely get rid of the partition of Windows 7? Try to remove it cause the laptop to be unable to boot because it seems that the boot files are still on the W7 partition.  Is there a way to make the W8 the 'boot' partition, perhaps by creating / copying the boot somehow files?

    Solved, here is how I fixed it in case someone else runs into a similar issue:

    1 installed and run EasyBCD on Windows 8

    2 open the BCD Backup/repair and C: set as default boot drive

    3 used Minitool Partition to delete the partition in which Windows 7 has been installed and extend Win 8 partition on unallocated space

    4 restarted, Dual Boot screen appeared, though there is only a single OS installed, so re-opened EasyBCD on Windows 8 and remove the entry from Windows 7 in Dual Boot menu

    Note that this is a VERY good idea to keep a Windows 8 installation disc/USB on hand at any time during this procedure, in case something goes wrong.

  • How Windows determines the dual-boot?

    I want to understand the mechanisms of multiboot.  Feel free to point me to the Microsoft links that explain this.

    How does he know how much OS bootable Windows are present?  Windows queries each partition at startup to see if an OS resides?  Or is a pointer added on the MBR as each OS is installed so that Windows should simply verify the MBR?

    Let me complicate the qustion slightly.  Suppose that disks are involved, each with a BONE or two.  If Windows asks each partition at startup to see if an OS resides, then disks does not alter.  However, if Windows stores this information in the MBR, how it works for several discs, each with its own MBR?  Windows look each MBR it can find at startup?

    Another question.  If Windows adds a pointer for each operating system on the MBR, then what happens if a BONE is removed, for example, when a partition is deleted or a diskette containing a BONE or two is physically deleted?

    Initialization information is contained in the store BCD and not the MBR.  The BCD store can be found in two locations.

    (1) hidden 150 MB system reserved partition.

    (2) in the score where the first version of Windows that you have installed. The folder is named C:\Boot and a bootmgr file name

    Whenever you install a different version of Windows (XP, Vista, Windows 7 or 8), another entry is made in the BCD store.

    How to modify the BCD store: http://technet.microsoft.com/en-us/library/cc731245%28v=ws.10%29.aspx

    An easier way to modify the BCD store is to install EasyBCD in the latest version of Windows you have installed.

  • Acer Travelmate 7750 G freezes completely using Windows or Linux (dual boot). Need help please.

    The problem is that the machine freezes completely without apparent reason, on all operating systems, I tried.  "Freezes", I mean there is no reaction to the mouse movements, keyboard presses and start button / stop pressed off the coast.  The gel seems to be at a random time and may occur even when the system is idle.

    The Acer Travelmate 7750 G laptop came pre-installed with Windows 7 and it kept freezing.  The machine has been updated level of Windows 8, 8.1, 10, then dual boot with Linux Mint 17.3.  The machine froze on all operating systems.  I have tested software hard drive, memory, CPU, GPU and they all managed very well.  Is it someone who has knowledge about how to resolve or others troubleshoot this please?

    RESOLVED - I installed a HDD replacement in December 2015 and the laptop Travelmate 7750 G works perfectly since.  Cost me almost nothing compared to the price of the laptop.  No freezing, crashing or anything else!

    Thank you very much for your help.

    I can install windows 7 in Envy DV7-7234 with Windows 8 buth with dual boot: win7 and windows 8?

    Installing Windows 7 on your HP ENVY computer Notebook dv7-7234nr is not supported by HP. In addition, no Windows 7 driver is listed on HP Software and Driver Downloads page for your computer.

    HP does not recommend installing Windows 7 and it will support the installation of Windows 7 on a computer comes with Windows 8. HP doesn't provide drivers for Windows 7 and the appropriate drivers are not available for the hardware in the computer. In addition, Windows 7 can not support some of the hardware or software designed for the computer.

    Make sure you create your media recovery HP or USB Flash Recovery discs before you edit or change anything.

    You will need to DISABLE 'Secure Boot' and ENABLE 'Legacy Support' in the ' settings of BIOS ' settings below page;

    Then, start Windows 8 and run the console 'disk management '. Using "Shrink Volume", reducing the size of the "C:" partition about half of its original size. Name of the partition "C:" to something like "Windows 8". Now, start the computer from the Windows 7 DVD, making sure to select "UEFI - internal CD/DVD" or "UEFI - ATAPI CD/DVD ' and not ' Legacy - CD/DVD internal."  (I recommend using a disc of Windows 7 SP1latest drivers have been included in this topic. The use of the SP1 disc usually resolves most disk hard AF and other issues. )

    Install Windows 7 on the partition without label that was established earlier when you shrunk the partition "C:". Continue to install WIndows 7 by / responding to all the guests. Once you download Windows 7 on your computer, we have to track down the compatible drivers for it. Please list all the "hardware ID" for unknown or missing devices.

  • Upgrade Windows 7 Home/Windows 10 Pro Dual boot computer CPU

    I plan on upgrading my CPU to a core of an I5 Quad model, dual Pentium G630. The card mother won't be replaced as it can accommodate a socket LGA-1155. I can also be tempted to replace my current system with a 250 GB SSD drive. It is a dual-boot computer that used to have two installations of Windows 7: it was OEM that came pre-installed, when the computer was purchased, and the other was a retail version. The OEM version updated to win Pro 8, then Win 8.1.1 and finally Windows 10 Pro.

    I would wait for activation or problems that this will be a smooth operation?

    If so, what might be the complications?
