Keep getting 'bootmgr is missing' message

[Skyliinez]

Hello, I'm after some advice. I've been getting this error message quite frequently over the past few months. It seems to happen every couple of weeks or so.

I had a Windows 7 Ultimate x64 machine when this first started happening. I work in IT so naturally I knew I could fix it by loading the Windows 7 disk and running the bootrec command, which did fix it at the time but a few weeks later it popped up again. I am able to fix this temporarily by using the bootrec command but it has not resolved my issue fully.

I thought upgrading to Windows 10 would do the trick in case there were missing or corrupted system files, but yesterday I saw the dreaded message again 3 weeks since I upgraded.

The only thing I can think of is that it could be the setup of my hard drives. I have 4 physical disks that are set up as standalone drives, no RAID used. My OS is stored on a 256GB SSD, with 3 other HDDs used for data, games and virtual storage. I checked the setup of each drive and my SSD is the only one set as my primary active drive.

I'm literally stumped! Can anyone offer some advice or give me an idea what else I could check?

Is anyone able to assist me please?

Allow me to try...
Could you open BIOS and grab a picture of the masters and slaves picture like this one?
Sometimes conflicts happen because the drive that has the OS isn't on top of the others.
-
Do you have any other Operating Systems installed on other HDDs?
Doesn't the windows automatic repair option fix it?

Hi, thanks for replying. I got pics of the BIOS screen below. The first 2 show the boot override configuration:

This one shows the SATA configuration:

And I included an image of my disk management in the GUI just in case.

I definitely think it's something to do with my BIOS, but I am unable to determine what. Naturally I looked at the boot override and changed it so the SSD (OCZ-VERTEX460A) was the first boot priority. After reboot I got the BOOTMGR message again. I then changed it to only have the SSD with everything else disabled. Still got the message. But the SSD is definitely the only drive to contain my OS. The samsung drive contains my virtual OS's on Virtualbox but I cant see that affecting it?

Virtual OSs wont affect it.
Can you try to disable fast boot and reboot the PC?
EDIT:
After disabling fast boot, press F12 (or whatever says BOOT MENU) to choose between the drives you can boot off of.

You need to make a recover partition.
Grab another Windows 7/8 machine and make a recover partition.
Go to Control panel -> Backup and restore -> left in the list there's a option to make a recover partition. Plug in a USB stick and let it do its job.
Then boot your machine on off of the USB.

I disabled fast boot and put the SSD as my first boot priority then selected it after reboot and I still got the message. However I was able to perform the bootrec repair off my Win 7 disk and so far have not had any problems. I think by disabling all my other HDDs from boot except my SSD I shouldn't have any more problems, but I will have to give it time.

Also, is there a Windows 10 repair disk I can create? I can use my Win 7 disk to run some commands but seeing as I'm using Windows 10 now it would make more sense to use a Win 10 disk.

I'm glad the you managed to do that. It should keep working flawlessly now.

About the other question, yes you can.
Here are the steps for creating the bootable repair disc:

1- In Windows 10, open Start menu or Cortana keyboard search (Windows Key+S), type backup and click Backup and Restore (Windows 7).
--If you cannot find the item, open Command Prompt (use Windows Key+X shortcut), type sdclt.exe and press Enter key to launch the program.
2- Create a system repair disc window opens. Select the correct drive and click Create disc.
3- Creating the System Repair Disc might take several minutes. After the process is complete, label the disc as instructed and click Close.
