Operating System Deployment task sequence fails with error 0x80091007

After imaging a few computers recently, two of them failed at the point in the task sequence where it was going to apply the operating system.  The error displayed was 0x80091007 which appears to be a generic error.

Rebooting the computer gives the (somewhat expected) message of ‘Bootmgr is missing’

I checked SMSTS.log on the local computer that had the error and the following information was shown…

The solution:

Changing the memory on the computer fixed the issue.




      • Hi

        Just want to say that i have had exactly the same problem

        Was going to reinstall a working XP machine to Windows 7 and it threw this error. Swapped ram with another machine and the first one installed OK.

        Then i tried installing the second machine that had gotten the bad ram, it failed also.

        Strange thing is that after i installed the machine where the bad ram was initially in, i put the bad ram back and now it runs just fine.

        My guess is that the problem lies in a memory address that the installer uses but the computer never uses.

        • Fixed the issue for me with an old Dell Vostro laptop. Took out the additional 1Gb memory stick and the SCCM OS deployment went through fine (though a bit slow with just 1Gb total RAM! 🙂
          Let the install finish and plugged in a new memory module. All good. Chucked the old one in the bin as although the OS may look like it’s working, I don’t want the user coming back to me in a few days or months with blue screen or lockup issues.
