Bootmgr ??

Hi BadrAl-harbi,

Thank you for posting your query in Microsoft Community.

This message usually indicates that the boot sector is damaged or missing. The boot sector is a region of your hard disk that contains information that is used to load your operating system. If a boot failure is
detected when your PC is starting, you may receive this error message.

Which OS are you are currently in?

Did you try the same step to install windows 7 from a DVD? I suggest you to perform the steps again.

• 
  Insert your Windows 7 DVD into your DVD drive and restart the system.
  
  (If you did not make a "Recovery DVD", borrow a like version of the Windows 7 DVD from a friend).
  
• 
  Boot the PC using the DVD by pressing any key when prompted.
  
• 
  Verify your language is correct and click
  'Next'.
  
• 
  Select the option named 'Repair your computer'.
  
• 
  The repair option then searches for the Windows Operating System. Once it has completed click
  'Next'.
  
• 
  Under Recovery Tool, choose the option named
  'Startup repair'.
  
• 
  Windows will "try" to repair your startup problem and will prompt you to restart the PC.
  
• 
  If you still get the "BOOTMGR is missing" error then repeat steps 1 to 7 again.
  
• 
  Restart your system to finish the process.
  

Do let us know if you have any other queries pertaining to Windows in the future. We will be happy to help.

Thank you.

 

fixing bootmgr missing

Hi Jonathan,

I appreciate the troubleshooting steps you have tried to resolve the issue. Do let us know the Edition of Windows 10 installed in your PC e.g. Windows 10 Home; Windows 10 Pro etc.?

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sectors, an outdated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.

Do you have Windows 10 installation disc with you?

Please follow the below steps to resolve the issue:

• Put the Windows installation disc in the disc drive, and then start the computer.

[*]

• Press a key when the message Press any key to boot from CD or DVD
  appears.
  
  If your PC does not detect the media automatically

• During the restart process, read the screen for any instructions that explain how to interrupt normal startup and enter the basic input/output system (BIOS) setup utility. Most PCs use the F2, F10, ESC, or DEL key to begin the BIOS Setup.
• Look for a tab in the BIOS Setup Utility that is labeled Boot Order,
  Boot Options, or Boot. Following the directions on the screen, use the arrow keys to go to the
  Boot Order, then press Enter.
• Locate the CD, DVD, or USB flash drive (this might be called Removable Device) in the Boot list. Following the directions on the screen, use the arrow keys to move the drive up so that it appears first in the Boot list. Press Enter. The boot order sequence
  is now changed to boot from the CD, DVD, or USB flash drive.
• Press F10 to save your changes and to exit the BIOS Setup Utility. Select
  Yes in the confirmation window. The PC will restart. Allow the PC to restart normally. The scan will take a few minutes and remove any malware that may be infecting your computer.

• Select a language, a time, a currency, a keyboard or another input method, and then click
  Next.
• Click Repair your computer.
• Click the operating system that you want to repair, and then click Next.
• In the System Recovery Options dialog box, click Command Prompt.
• Type Bootrec /RebuildBcd, and then press ENTER.

Please reply with the results, we will be glad to help you further. Thank you.
