So rebuildbcd works, yet can’t find the bootmanager. The Microsoft article fixes the boot entries on the drive but will point to the bootmanager on the non-active drive. If the system reserved partition isn’t marked as active, which can happen due to incorrect partitioning. This problem can appear after you fiddled with drive partitions using disk utility or third party software. Remove your USB stick and if all went well you’ll be seeing your Windows logo instead of the bootmanager missing error. Diskpart will report the partition is now active.

Diskpart will report “Partition N is now selected”. It’s a small primary partition and usually it’s the first entry. Then select your boot drive by typing “select disk N” where N is your boot drive.

Locate your boot drive (disconnecting external drives helps). Wait for it to load and type “list disk”. This path seems weird but it’s actually located in the root of the hidden system reserved partition. It’s there, but for some reason your system can’t find this path. If the path is “ootmgr” you’re close to a fix. Pay notice to the Bootmanager entries and in specific the path. Go back to cmd and type “bcdedit” and check the entries. Reboot to the hard drive and try your luck. In the installer go to the repair options and select the cmd option. I fixed my error the following way, maybe this will work for you:Ĭreate a Windows 10 installer USB on a different machine.Ĭhange your bios settings to boot from this stick. Are you experiencing this error and did the Microsoft Support Articledo nothing for you?
