What you can do here first for this problem is to go to your BIOS settings and change the boot priority make sure your hard drive is the first boot device and also make sure there's no USB drive connected to your computer when you restart it.

My laptop says bootmgr is missing and i dont know how to fix


First make sure that all usb devices are unplugged and remove all cd's or dvd's or sd cards etc.
If you are running Windows 7 or Vista you can try do a repair by hitting F8 while it boots and then select repair. If this does not work you will need a install disc. If you have Windows XP you will need an install CD to do a repair. I have attached a few links that may help explain in detail. Thanks for using fixya.

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.

Boot Manager is missing If the boot partition no longer can be found, then Vista will display the following error: BOOTMGR is missing. Press Ctrl+Alt+Del to restart
The Windows Boot Configuration Data file is missing required information
More Info MS KB 919529 More Info MS KB 927391 Check points for fixing missing boot-manager: Check that your boot device is configured properly Boot into Windows Recovery Environment (WinRE) and perform a "Startup Repair". Boot Manager is compressed If by accident having compressed the entire boot partition, then Vista will display the following error: BOOTMGR is compressed. Press Ctrl+Alt+Del to restart OR maybe try this first. Check points for fixing compressed boot-manager: Boot into Windows Recovery Environment (WinRE) and perform a "Startup Repair". If the above doesn't solve the problem then boot into WinRE again, but when selecting the Vista-installation, then press "Load Drivers" (Instead of "Next") and use the mini Windows Explorer to right-click the boot-drive and deselect "Compress this Drive" and choose Apply to sub-folders and files. If that also fails then boot into WinRE again, and go to the "Command Prompt" and execute these commands: compact /U C:\bootmgr compact /U C:\ntldr If you for some strange reason have lost your Vista DVD, then you can also use a Windows 2000 / XP install CD and enter the recovery console instead and execute the following commands: attrib -c c:\bootmgr attrib -c c:\ntldr


Try start up in Safe Mode press F8. Choose Safe Mode, when at the choice window, to select either Safe Mode Desktop, OR System Restore, chooses system restore and choose a time before you had the "Problem" and follow instructions. This should get you back.

You boot sector on the hard drive is faulty.

Fixing "BOOTMGR is missing" Error While Trying to Boot Windows Vista If your Windows Vista computer has encountered the dreaded “BOOTMGR is missing” error, you aren’t alone. If the problem isn’t hardware related you can fix it with relative ease as long as you have a Windows Vista DVD handy.
If you don’t have one, you can create a Windows Vista repair disk using our guide.

Boot off the Windows Vista DVD and then click Next at the first prompt:
image16.png
You should see a link in the lower left-hand side for “Repair your computer”
image17.png
The installation process will attempt to find your Vista installation directory. If there’s more than one in the list, select the correct one and then use the Next button again.
image18.png
Click the first link for “Startup Repair”
image19.png
The installation process will repair the system, and then prompt for you to reboot.

Alternatively you could have chosen the Command Prompt option instead, and use the following command to fix the boot options only:
bootrec /fixboot

At this point you should be able to reboot your computer, remove the DVD and everything should be working.
