HOW DO I GET MY PC TO LOAD THE NEW OS WHEN I KEEP GETTING AN ERROR MESSAGE SAYING BOOTMGR IS MISSING?


If you are on a computer that you usually use, and you get this message, it means that the Operating System startup files are corrupted, or erased. If you want to upgrade your PC to a new operating system, you need

1. to get a DVD of the new operating system,
2. Put it in your DVD drive
3. Turn on your computer. When your computer is turning on, press the F?? key that is displayed on your monitor when it starts up that says "Boot menu"
4. When the boot menu appears, tell your computer to boot from the DVD. When it finds the DVD, it will start your computer with the new operating system. Some operating systems allow you to repair your desktop/laptop, if the DVD is the same operating system that is on your desktop/laptop.

I have an asus netpad for daughter but its missing ntldr file and keeps repeating cntrl- alt-del and wont go to boot up squence? i was originally trying to put larger hdd inside but same model though .is...


When you install a new hard drive into any computer, the operating system needs to be installed because new drives typically come blank. So when it says Ntldr is missing that is the computer bios telling you that there is no operating system for it to boot, or if there is one on the drive it is damaged beyond repair and must be reinstalled. So get your Windows install disk and boot from the cd (usually will automatically when disk is in the drive) and reinstall the OS. If there is no optical (CD) drive, then you'll have to make a USB boot drive on a flash drive with the install CD on another computer and use it to boot from and install the OS.

I have just installed a new, blank hard drive. when I try to install the operating system from a CD, the PC will not boot with the message BOOTMGR is missing. The Bios sees both the new hard drive and


It sounds like you are trying to install Windows 7, if this is the case then put the instalation disk into the drive and run the 'repair' option.
With Windows 7 it should fix the problem automatically.

Hp dv6000 will not oot all the way


You've got either a corrupt or missing boot files or system files. You will need a repair disc or a system disc to fix this problem. If you have such a disc put it in the cd drive and boot from it. You want to get to the recovery console so that you can type the following dos command in the black window that appears with white text. The command is: chkdsk /r
Check disk will run well over an hour so be patient. You will also see the percentage of completion going from high to low but that is normal. Just let it run to completion then reboot your machine. Check disk will repair or install corrupt and missing boot and system files. If it does not boot then you will need to reinstall your operating system. Try to a repair install to an existing operating system instead of a new install. The repair install will preserve your data, docs, music, pics and videos. The new install will wipe them out.

Bootmgr missing


Causes of BOOTMGR ErrorsThere are a number of possible causes for BOOTMGR errors, including the most common "BOOTMGR is missing" error message.

The most common reasons for BOOTMGR errors include corrupt and misconfigured files, hard drive and operating system upgrade issues, corrupt hard drive sectors, an outdated BIOS, and damaged or loose IDE cables.

Another reason you might see BOOTMGR errors is if your PC is trying to boot from a hard drive or flash drive that is not properly configured to be booted from. In other words, it's trying to boot from a non-bootable source. This also would apply to media on an optical drive or floppy drive that you're trying to boot from. Fixes for BOOTMGR Errors
  1. Restart the PC. The BOOTMGR error could be a fluke.

  2. Perform a startup repair of Windows. This type of installation should replace any missing or corrupt files, including BOOTMGR. Continue troubleshooting if this does not resolve the issue.

  3. Check your floppy and optical drives for media. Often times, the "BOOTMGR is Missing" error will appear if your PC is trying to boot to a non-bootable floppy disk or CD/DVD.

    Note: If you find that this is the cause of your issue and it's happening regularly, you might want to consider changing the boot order in BIOS so the hard drive is listed as the first boot device.

  4. Check the hard drive and other drive settings in BIOS and ensure they are correct. The BIOS configuration tells the computer how to use a drive so incorrect settings can cause problems, including BOOTMGR errors.

    Note: There's usually an Auto setting in BIOS for hard disk and optical drive configurations which is usually a safe bet if you're not sure what to do.

  5. Reseat all internal data and power cables. BOOTMGR error messages could be caused by loose or malfunctioning power or controller cables.

    Try replacing the PATA or SATA cable if you suspect it might be faulty.

  6. Update your motherboard's BIOS. An outdated BIOS version can sometimes cause the "BOOTMGR is Missing" error.

  7. Perform a clean installation of Windows. This type of installation will completely remove Windows from your PC and install it again from scratch. While this will almost certainly resolve any BOOTMGR errors, it's a time consuming process due to the fact that all of your data must be backed up and then later restored.

    If you can't gain access to your files to back them up, understand that you will lose them all if you continue with a clean installation of Windows.

  8. Replace the hard drive and then perform a new installation of Windows. If all else has failed, including the clean installation from the last step, you're most likely facing a hardware issue with your hard drive.
BOOTMGR Errors Apply To BOOTMGR issues apply to Windows 7 and Windows Vista operating systems only. Windows XP does not utilize BOOTMGR. The equivalent function in Windows XP is NTLDR


Whish you the best luck.

NTLDR is missing


Fixes for NTLDR Errors
  1. Restart the PC. The NTLDR error could be a fluke.

  2. Check your floppy and optical (CD/DVD) drives for media. Often times, the "NTLDR is Missing" error will appear if your PC is trying to boot to a non-bootable floppy disk or CD/DVD.

    Note: If you find that this is the cause of your problem and it's happening a lot, you might want to consider changing the boot order in BIOS so the hard drive is listed first.

  3. Check the hard drive and other drive settings in BIOS and ensure they are correct. The BIOS configuration tells the computer how to use a drive so incorrect settings can cause problems, including NTLDR errors. There is usually an Auto setting for hard drive and optical drive configurations in BIOS which is usually a safe bet if you're not sure what to do.

  4. Restore the NTLDR and ntdetect.com files from the Windows XP CD. Restoring these two important system files from the original Windows XP CD may do the trick.

  5. Repair or replace the boot.ini file. This will prevent the NTLDR error if the cause of the problem is a boot.ini file that is not configured properly for your Windows XP installation.

  6. Write a new partition boot sector to the Windows XP system partition. If the partition boot sector has become corrupt or isn't properly configured, you may receive the "NTLDR is Missing" error.

  7. Repair the Windows XP master boot record. NTLDR error messages may also appear if the master boot record is corrupt.

  8. Open your computer's case and ensure that the cable that connects the hard drive to the motherboard is firmly in place. If this does not resolve the issue, try replacing the cable. NTLDR error messages could be caused by loose or malfunctioning IDE cables.

  9. Update your motherboard's BIOS. Occasionally, an outdated BIOS version can cause the "NTLDR is Missing" error.

  10. Perform a repair installation of Windows XP. This type of installation should replace any missing or corrupt files. Continue troubleshooting if this does not resolve the issue.

  11. Perform a clean installation of Windows XP. This type of installation will completely remove Windows XP from your PC and install it again from scratch. While this will almost certainly resolve any NTLDR errors, it is a time consuming process due to the fact that all of your data must be backed up and then later restored.

    If you can't gain access to your files to back them up, understand that you will lose them all if you continue with a clean installation of Windows XP.

  12. Finally, if all else has failed, including the clean installation from the last step, you're most likely facing a hardware issue with your hard drive. Replace the hard drive and then perform a new installation of Windows XP.

Booting problems with my Toshiba Satellite P105


Try to reinstall the video driver from Safe mode.
It appears your hard disk is OK but the operating system and or registry is corrupted.
1. Try installing the video driver first.
2. If it still does not work, back up your data files in Safe Mode then re-install XP again, make sure you delete the partition and create a new partition and do a full NTFS format, not a quick format.

Missing Operating System error


your bought compag computer is a new one , because that error is appears only if the hard drive or the harddisk is defective or damage. Your installation of windows xp is finished totally because sometimes the error is appears because the system installation is not finished and the os system cannot read. try to re install again the windows and delete the old partitions and create again if the problem is the same even there is no error in the installation until it's finished i say that the problem is in the harddisk. Maybe the harddisk develop a bad sector in the master boot record of the hardrive
