10 Steps Solution for BOOTMGR Error

As computer user you all have faced the common error i.e. BOOTMGR is missing? Most of the people don’t know about the BOOTMGR is the hidden system file in the C: root directory.  For Windows Vista, the boot sector loads the Windows Boot Manager, which first looks for an active partition, then accesses the boot configuration data store and uses the information to load the operating system. Windows boot manager was first introduced in Microsoft Windows Vista that reads the boot configuration data and displays the operating systems selection menu. For earlier version NTLDR (NT loader) was used. This is a program loaded from hard drive boot sector that displays the Microsoft Windows NT startup menu and helps Microsoft Windows NT/2000/XP load. Now this appears as BOOTMGR in later windows versions which are Windows Vista, Window 7 and Window 8.

                         

Causes of  BOOTMGR  error:-

• The most common reason for the BOOTMGR missing error is corrupted and misconfigured files.
• Sometimes it can be caused due to operating system upgrade issues and corrupted hard drive sectors.
• Outdated BIOS (basic input output system).
• Computer hard drive is not properly setup in CMOS.
• Computer is booting from a non-bootable source.
• Damaged or loose hardware interface cable can also cause this error.

Steps to fix BOOTMGR Error:

1. Restart your computer.
2. Now check your optical drives, USB ports and floppy drives for media. Seldom BOOTMGR error occurs if your computer is trying to boot from non-bootable disc. If you find this is the cause for your problem then you have to change the boot order in BIOS so the hard drive is selected as the first boot device.
3. Sometime BOOTMGR error could be caused due to lose or unplugged power and data cables. So try to reseat all internal data and power cables in proper way.
4. Sometime due to corrupt hard drive sectors computer shows BOOTMGR error. For fixing it you can do Startup repair of windows operating system including Windows vista, Windows 7, Window 8. This type of installation will replace any missing or corrupt files, including BOOTMGR. If you face any problem while installing Windows operating system like Window 7, Window 8 etc then you can take help form IMPCSUPPORT they will diagnose your entire problem and offer Instant PC solution.
5. If the partition boot sector becomes corrupted or misconfigured in some way, then Windows won’t be able to start properly and cause an error like BOOTMGR is missing in the boot process.
6. The solution to a damaged partition boot sector is to overwrite it with a new, properly configured partition boot sector using the Bootrec command. 
7. Damage of boot Configuration Data can also be the cause of BOOTMGR error. For eliminating this you have to rebuild the Boot Configuration Data (BCD).You has to use Bootrec command to build the BCD.
8. Check the hard drive and other drive settings in BIOS and make sure they are correct. The BIOS configuration tells the computer how to use a drive so incorrect settings can cause problems, including 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. An outdated BIOS version can sometimes cause the "BOOTMGR is missing" error. For eliminating this problem you should update your motherboard’s BIOS regularly.
10. Install upgraded Window which will fix all the missing files causing the BOOTMGR error. This type of installation will completely remove Windows from your PC and install it again from scratch. This action will certainly resolve any BOOTMGR error but before doing this it is always advised to make a backup all your data as this installation can remove all your data so by doing backup it can be restored.
11. If you have followed the above steps and still you have the problem then you’re most likely facing a hardware issue. So in my opinion you have to replace your hard drive and then install a new copy of Windows.
