Fixing "BOOTMGR is missing" Error While Trying to Boot Windows Vista

If your Windows Vista computer has encountered the dreaded "BOOTMGR is missing" error, you aren't alone. If the problem isn't hardware related you can fix it with relative ease as long as you have a Windows Vista DVD handy.

If you don't have one, you can create a Windows Vista repair disk using our guide.

Boot off the Windows Vista DVD and then click Next at the first prompt:

image

You should see a link in the lower left-hand side for "Repair your computer"

image

The installation process will attempt to find your Vista installation directory. If there's more than one in the list, select the correct one and then use the Next button again.

image

Click the first link for "Startup Repair"

image

The installation process will repair the system, and then prompt for you to reboot.

Alternatively you could have chosen the Command Prompt option instead, and use the following command to fix the boot options only:

bootrec /fixboot

image

At this point you should be able to reboot your computer, remove the DVD and everything should be working. If not, then head over to our forums and ask your question there. We've got some top-notch geeks over there!

    I don't know why, but both times I've used the Startup Repair I had to run it twice. So if the first time doesn't fix it, boot from the Vista DVD again and run it a second time.

    After Booting off the Windows Vista DVD and then click Next at the first prompt.
    Then I click on the link in the lower left-hand side for "Repair your computer"
    but at the System Recovery Options, the microsoft windows vista OS is not showing to continue by clicking on next.
    Expect your reply.
    Thank you

    I've had this problem three times, twice I've used the vista repair option and they only worked for that boot-up, Its not a permanent fix. I have noticed however that my pc boots straight into windows with no probs if I leave the vista disk in my pc, very strange.
    Maybe I should copy the bloody file off the cd and paste it somewhere, but where ?.
