Replace Bootmgr Windows 7

 admin

There 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 hard drive interface cables.

Nov 16, 2016  Bootmgr Is Missing Press Ctrl+Alt+Del To Restart Windows 7 - Fix it Latest Windows Secrets. The when i rebooted windows 7 it came as 'BOOTMGR is Missing' So I put in the windows vista CD and got the windows vista BOOTMGR. I don't have the windows 7 CD. Everything is working fine in the setup file of windows 7 there is a file named BOOTMGR.

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.

There are few ways that the 'BOOTMGR is missing' error may show up on your computer, with the first error I have listed being the most common:

The 'BOOTMGR is missing' error displays shortly after the computer is turned on, immediately after the Power On Self Test (POST) is complete. Windows has only initially started to load when the BOOTMGR error message appears.

BOOTMGR issues apply to Windows 10, Windows 8, Windows 7, and Windows Vista operating systems only.

Windows XP does not utilize BOOTMGR. The equivalent function in Windows XP is NTLDR, which produces the NTLDR is Missing error when there's a similar problem.

How to Fix 'BOOTMGR Is Missing' Errors

  1. Restart the computer. The BOOTMGR error could be a fluke.

  2. Check your optical drives, USB ports, and floppy drives for media. Often times, the 'BOOTMGR is Missing' error will appear if your PC is trying to boot to a non-bootable disc, external drive, or floppy disk.

    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.

  3. Check the boot sequence in BIOS and make sure the correct hard drive or other bootable device is listed first, assuming you have more than one drive. If the wrong drive is listed first, you could see BOOTMGR errors.

    I know I sort of hit on this in the troubleshooting step above, but I wanted to call out specifically that you might have the wrong hard drive listed since many BIOS/UEFI systems allow you to specify a particular hard drive to be booted from first.

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

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

  5. Perform a Startup Repair of Windows. This type of installation should replace any missing or corrupt files, including BOOTMGR.

    Even though a Startup Repair is a common solution for BOOTMGR problems, don't worry if it doesn't fix your problem. Just continue troubleshooting - something will work.

  6. Write a new partition boot sector to the Windows system partition to correct any possible corruption, configuration problem, or other damage.

    The partition boot sector is an important piece in the boot process, so if there's any issue with it, you'll see problems like 'BOOTMGR is Missing' errors.

  7. Rebuild the Boot Configuration Data (BCD). Similar to the partition boot sector, a corrupted or incorrectly configured BCD could cause BOOTMGR error messages.

    The following troubleshooting steps are much less likely to help fix your BOOTMGR problem. If you've skipped any of the above ideas then you may have overlooked a very likely solution to this problem!

  8. 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 like BOOTMGR errors.

    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.

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

  10. 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, please understand that you will lose them all if you continue with a clean installation of Windows!

  11. Replace the hard drive and then install a new copy 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.

  12. Assuming it's not a hardware issue, your BOOTMGR should be fixed.

Why BOOTMGR is missing appears

When you turn on the computer, the POST (stands for Power On Self Test) processes begin to run by BIOS before booting your Windows copy. The error appears right after the POST process is completed and Windows starts to load.

The POST is a set of routines that are run immediately when starting the PC, such as checking if your RAM, peripheral devices and other hardware components your PC has are working correctly.

After these routines are completed by BIOS, the Windows boot loader begins, where this error is going to appear. Winzip 14.5.

The BOOTMGR error can be caused by many things, including boot sector viruses, failed Windows installs or updates or crashed hard disks.

The first and easiest fix is to check for any existing media in your USB ports, floppy drives or optical drives (CDs, DVDs).

BOOTMGR error will appear if your computer is trying to boot from one of these drives that have a non-bootable media inserted. Once you remove a USB drive or CD from which the computer was trying to boot from and couldn’t, the error should disappear.

After it disappears, consider changing the boot order from BIOS to make sure your PC boots from the hard drive and not from any other non-bootable drives next time.

Fix #5: Use bootrec.exe to fix the boot

The partition boot sector is stored on the hard disk drive and contains the necessary code to start the Windows boot process. If this partition is corrupt or not properly configured during a Windows install it would lead to “BOOTMGR is missing or corrupt” errors at startup.

This method needs a copy of your original Windows installation disc.

AliasesI frequently use the l alias that my enables, and we can set up the same behavior using Cmder's command prompt aliases.The command prompt alias file is inside your Cmder folder under config, called useraliases.cmd. I add the following, copying much of the existing ls alias: l=ls -show-control-chars -color -laF. The task can also be launched directly from the plus button or new console dialog.Cmder settings carry over, like fonts and themes. Cmder bash profile. Cmder augments the command prompt with (stuff like tab completion) and, so it can actually behave fairly similar to Linux for some tasks. Open that file ( vim is available on the command prompt) and you'll see the existing aliases.We can add a new one by adding a new line, but be aware that referring to other aliases doesn't work like it does in Linux; we have to be verbose instead.

Here are the steps to fix this error using the bootrec.exe tool, the same tool used in Fix #4 above:

  1. Insert the Windows 7 or Vista install disc
  2. Restart your computer and boot from the disc
  3. Press any key at the “Press any key to boot from CD or DVD” message
