[SOLVED] Boot Manager Missing

[ISHYY123]

Hi,


I'm unable to boot my HP Compaq 6910p laptop to Win 7 Pro, due to a 'Missing boot manager missing' message appearing.

I have exausted all the solutions including -


Control/Alt/Delete

Confirmed primaryHdd is first in the booting order

bootrec solution in Run/Dos

sfc /scannow

chkdsk

Power cabels ok




Sadly the laptop has evolved to having none of the following -

Safe option/system restore/Run-Dos option/repair option/diagnostics option/blue screen stop errors have stopped appearing/restart option/all 'F' options to choose from on blue screen

The only 'F' key option that responds is F10 - for Computer setup - File/Security/Diagnostics - HDD Self test - Memory check - Startup check - these appear ok/ system configurations/boot options - HDD is first in boot order

Start up check success on testing - STATUS - PASS

When I insert the repair DVD, I changed the DVD boot order to first

When I start the laptop, to attempt to repair, I insert the DVD and the Missing Boot Mananger message appears but the Windows repair CD doesn't activate ( When I insert the Win 7 DVD repair options on my Acer, all on the DVD, so working ok) CD/DVD Rom player working ok on HP laptop.

Both computers boot ok when inserting alternative Win OS.

There are numerous options on Yotube to solve this problem but I am unable to try any ouf them due to the issues above

I don't want to reinstall, I want to repair problem so I can use existing OS on HDD

Any help would be appreciated.

Thanks


Ishy

Sounds like your boot drive is corrupted; you might not have a repair choice.

You might be able to try to repair the MBR using console commands w/the repair options, but this rarely works.

You'd have to do some diagnosing, before appropriate fix can be determined.

Could be several issues:

bootmgr file missing on bootloader partition;​

bootloader partition corrupted;​

if there's no separate bootloader partition, OS partition can be corrupted.​

First boot from windows installation media (windows 7 installation media, if your OS is windows 7).
Go into command prompt by pressing Shift+F10.
Execute following commands and make a photo of screen output and post it (upload to imgur.com and post link)

diskpart​

list disk​

select disk 0​

list partition​

list volume.​

Generally you should be able to fix it with bcdboot command:

bcdboot C:\windows /s H:​

(C - windows partition, H - bootloader partition, note drive letters most likely will be different in windows installation environment)

But if OS partition is corrupted, you'll have to reinstall anyway.
There's no other way around it (other than restoring from backup, which you probably don't have).
