When you get an error on your PC saying it cannot boot, things are looking south. But this is not the apocalypse; it can be worked around. Oftentimes, a simple restart will suffice to make the problem stop bothering you, but that is not guaranteed to work in every instance. So how to fix Bootmgr is missing issues in Windows 8?
There is a native Automatic Repair tool you could use, for starters. This is part of the installation disk you used to set up the OS. Here is how to go about it.
- While the machine is still powered on, use the Ctrl + Alt + Delete combo and do a restart. As it was mentioned above, this might do enough repairs. If not, move on to the next step.
- Put the Windows 8 installation disk in the optical drive, and use the Ctrl + Alt + Delete combo once more. If you got a USB stick instead of a DVD, then plug that in before restarting.
- You will be asked to press any key to boot from the connected drive – DVD or USB. Detection of either is done automatically in Windows 8.
- If asked, select the settings for language, time, currency, and input method. For now, choose the keyboard as the input method.
- Choose the Repair your computer option and then choose Advanced options from the Troubleshoot
- From this screen, choose Automatic Repair, so the PC runs a diagnostic to see what is causing the Bootmgr issue.
- Wait while the repair process is over. Over the course of this, the PC might restart a few times, so sit through that.
If Automatic Repair doesn’t work
- Plug in the installation media and restart the computer. Go through the same steps, as before until you get to Advanced Options where you need to choose Command Prompt this time.
- Type in Bootrec /RebuildBcd and hit Enter. This will hopefully rebuild the boot config data. If that does not solve happen, then a System Restore is the only viable option left.
Boot once more with the installation media plugged in. Choose System Restore when you get to Advanced Options. Select a usable restore point from the list shown after the prompts, and hit Finish to roll back into it.
That was on hot to how to fix Bootmgr is missing error in Windows 8. If you did not have System Restore set up before that, and neither of the other methods worked, you might need to call tech support to help you out.
