Now that we know the possible causes of the error: BootMgr is missing, let us jump directly to the methods to get rid of this error once and for all.
HOW TO FIX ERROR: BOOTMGR IS MISSING
The error BootMgr is Missing can be fixed in a number of ways depending upon the root cause. However, it is very difficult to pinpoint the root cause and thus we will have to try out a number of methods until the issue gets resolved. For that reason, we have listed all the possible methods to fix the error BootMgr is missing. So, let us get started.
METHOD 1: EJECT ALL REMOVABLE DEVICES: USB DRIVE, CD, DVD ETC
If you have attached an external device (such as USB drive) to your system, BIOS looks for the Boot Manager in these external devices (if the BIOS settings are configured to boot from the removable device).
However, if the external device that is being attached is not bootable, BIOS will never find the Boot Manager in it. Hence, it will give the error BootMgr is Missing. That certainly makes sense, isn’t it?
So better remove all the removable devices that you have attached including USB Drive, external hard drive, CD, DVD, etc. Once you have removed everything, try to restart your system and check if the error BootMgr is missing still persists.
However, if you do not have any external device attached to your machine, simply ignore this method as this is not applicable to you. Try implementing the other methods that we have given below to fix the error BootMgr is missing.
METHOD 2: CHANGE BOOT ORDER IN BIOS SETTINGS
BIOS settings are responsible for defining the Operating System boot order. In case you are using more than one hard drive, you need to define the order in which OS should be loaded. This method may look a bit tough, but it is very easy. All you need to do is carefully follow the steps that we have listed below.
- Restart your system and keep pressing the F2 key as the system starts. This will take you to the BIOS screen.
- Go to Boot option from the top menu bar.
- This will display the boot order. Make sure you have Hard Drive on the top. If it is not on the top, bring it on top and save the changes.
- Now restart the system so that changes can take effect. This should resolve the issue of BootMgr is missing.
