bootmgr is missing

[swtscp]

i got windows 7

 

[failblox]

Did this happen randomly or were you messing around with something?

(please give us more details and your specs)

[Burusutazu]

You need to use a windows 7 instillation disk that matches your version (ex. Home Premium 64x) to go into the command prompt and use the command fixmbr.

[swtscp]

it happened randomly

 

I tried to repair it with a usb key (windows 7 is on it) and the drives were locked

[swtscp]

fixmbr is not recognized as an internal or external command, operable program of batch file

[swtscp]

i tried bootrec.exe /fixmbr it says that the operation was succesful but my problem is still there

[Burusutazu]

Then your problem is beyond my knowledge. Hopefully someone else will know more about your problem, I can only think about reinstalling at this point.

[swtscp]

when i try to repair it says that the drive where windows is intalled is locked even after doing bootrec /fixmbr

[swtscp]

please help

Edit: Actually before you do any of that can you try resetting your BIOS/UEFI to default settings.

 

did you make sure you selected the right drive to repair the bootloader?

 

run your installation disk select your language and keyboard layout.

then choose repair computer > advanced > command prompt

diskpart

starts diskpart

sel disk 0

selects first disk. (I would suggest unplugging all other drives for simplicity)

list vol

lists partitions on selected disk

From this list you want to find the FAT32 volume take note of the volume number

(you will also want to take note of your windows partition drive letter for later)

sel vol 4

selects appropriate volume

vol 4 is an example but this number wants to be the number of the fat32 volume

assign letter=t:

assigns letter t: to volume 4

exit

exits diskpart

 

now you want to repeat what you tried with repairing the bootloader

cd /d t:\EFI\Microsoft\Boot\bootrec /rebuildbcdbootrec /fixboot

Now to rebuild the BCD.

 

backup your bcd

ren BCD BCD.bk

renames BCD to BCD.bk

bcdboot c:\Windows /l en-us /s t: /f ALL

takes files from your C drive and copies them to the boot partition in english US language

now a couple of things to note here c: won't always be your windows partition pay attention when in diskpart to check which partition is your windows one and if it is a different letter then use that instead of c: (this will be an issue if you installed linux before windows)

the second thing is that you way not be using the US locale for me here in aus it would be en-au in england it would be en-gb in germany it would be de so make sure you get the correct locale as your windows install (There is a list of language codes here if you're unsure) So make sure you use your language code and replace en-us

 

Then reboot and remove your installation media.

 

So this is my post from a different thread. It should work for you though. Ignore the random bits of text scattered through though. also I've changed one part in red for you.

the bcdboot.exe command-line tool is used to copy critical boot files to the system partition and to create a new system bcd store.

/l

/s

/v

 what am i missing did it work?

[swtscp]

I just rebooted and it says

An operating system wasnt found. try disconnecting any drives that dont contain an operating system.

[SubTract]

It's possible your HDD is dead. or at least dying.

[dragoon20005]

yup this is a pattern that indicates a dying HDD

 

because the Bootmgr is getting corrupted and repairing didn't work

 

 

you need a to get a new HDD and rebuild the OS

 

and try to see if you can extract the data from the dying HDD

i tried bootrec.exe /fixmbr it says that the operation was succesful but my problem is still there

also try a bootrec.exe /fixboot

 

failing that you need to use bcdedit to re-build the 'boot sector'.

 

being too lazy for that you can just re-install windows.
