Windows 7: Bootmgr Missing

Bootmgr Missing

My computer downloaded and installed updates 2 days ago. I didn't pay much attention except to check if they were important or optional.
My computer goes to restart and now it won't boot.

I take out my original installation disc and my recovery disc which is on a usb stick. Using the installation disc I get an error message that the version of system recovery options is not compatible with the version of Windows I am trying to repair.

Using my recovery usb stick, I get to removing old BCD, creating new BCD, restart and then same error.

Please see the attached pictures.

I hope someone can help walk me through what needs to be done.

I am running Windows 7 Ultimate. You can see my build in my signature.

You could try using bootsect to fix the bootmgr issue. However, macrium is claiming it to be a gpt disk - is that correct?
If so, you can attempt to fix it using bcdboot from command prompt


But you might have more of a problem than just that.

Restore an image if you have one. If not, you can use my boot media to see if you can restore from a shadow copy ( shadowcopyview is in the boot media)

create a bootable usb from iso using rufus, or similar

Rufus

If your system is installed in efi mode, you need to boot the media in efi mode.

Thank you SIW2 for your reply. It is now morning here where I live and I am about to go to work. I will try everything you suggest this evening and let you know how I get on.

The only other computer I have access to is a work macbook air. So instead of Rufus, I am using a piece of software called balenaEtcher. I hope this is suitable.

I will keep you posted and thanks again.

You're booting Win7 in UEFI mode, you just installed Aug updates, and you're getting a 0xc0000428 error. That meets the exact conditions described in this thread in another forum. Perhaps you can find something useful in that thread.

That thread is based on these articles:

Following dg1261 useful link, it seems you need to install KB 3133977.
Installing Windows 7 from a backup? You need a BitLocker patch right away | Computerworld

You can do that from the boot media I posted. There are two suitbale version of my boot media. They both contain dism++ which can be used to install the KB 3133977 into your non booting system.


First download KB 3133977 and keep it somewhere you can get at it, e.g. a flashdrive.
https://download.microsoft.com/downl...133977-x64.msu



Then boot my boot media in efi mode.
Start dism++ from the desktop icon.
Click the non booting os at the top of dism++ windows so it turns blue.
Click Updates in the left pane
Click add and browse to wherever you put KB 3133977


Unclear as to whether you ned to run bcdboot after that. I would to be sure.

Probably wise to stay away from windows update, use dism++ every month to update, or better still - Simplix pack.


Current Simplix pack

Thank you both.
I am trying to get hold of a Windows machine so as to be able to use Rufus. Might be able to get one in a day or two. I will keep you posted.

You can burn this direct to cd/dvd if that is easier. Dism++ is included in the wim.

(Ignore the warning dism++ gives about less than 5gb scratch. You don't need that much to install one update )

Just tried to make bootable usb drives using balenaEtcher, no luck.
Hope to be borrowing a windows laptop from work tomorrow so will be able to burn a cd and use Rufus.
Cheers

Not sure what I'm doing wrong.
When I try to use the "Add drivers" function, the software does not see the driver that is in the folder.

The driver is named "Windows6.1-KB3133977-x64.msu"

It's there when I check the usb stick on another laptop, but my pc cannot see it.
Any ideas on what I may be doing wrong?
