You may wonder what is BOOTMGR?

BOOTMGR stands for Boot Manager. Boot manager is stored in whats called configuration data aka BCD or Boot Configuration Data. Boot manager is solely responsible for turning it over to the Windows Boot Loader (Winload.exe). Which will then load Windows kernel aka ntoskrnl.exe. Its part of the bootstrap process basically.
[alert-note]Note before BOOTMGR the first sequences in the boot process is actually stated by the Boot sector.[/alert-note]

Possible variables to the problem

  • Loose SATA connections.
  • Bad HDD can cause this problem, specifically sectors could be damaged.
  • Possible outdated BIOS could cause this issue
  • As mention Boot Configuration Data might need to be rebuilt/boot sector as well.
  • It’s quite possible that the volume boot recorder /Master Boot Recorder is bad which would need to write new one due to rootkits/bootkits

What we know..

is that this issue relies before the winload.exe.

Lets start..

  1. Check for any loose connections with your SATA port and from the HDD. Move to next step when done.
  2. Go ahead run Hard Drive Diagnostics. Western Digital or Seagate has their own diagnostic tools. Also you could try manufacturer diagnostics tools. Hard Drive passed? Yes or No
  3. No, go ahead get your data off and replace HDD. If yes, then lets start with booting into Windows Advanced Boot Option Menu. Hold down the “F8” Key until you get into Advance Boot Option. Go ahead in go to system Recovery Option.
  4. Try to run Startup Repair if this does not work follow the next steps.
    1. If the above does not work, go back to System recovery options and load Command Prompt
    2. From command Prompt lets type this
    3. bootrec /fixmbr (Overwrites the boot recorder)
    4. bootrec /fixboot (Overwrites the boot sector)
    5. bootrec /RebuildBCD
    6. Reboot
    7. ???
    8. PROFIT?!
  5. If the above did not work you might need to try the following (Make sure you know what partition is active before doing this command, use tool like diskpart for this.) Drive letter c: assumes that is the active partition.
  6. Command Prompt type bootsect /nt60 c: (This will update the Volume Boot Code on the partition used to boot windows into BOOTMGR). This is only for Vista/7/8
  7. Profit?!
