My computer has been having problems restarting ever since I added hypervisor to my bcd so I tried to delete it but ended up deleting the entire bcd. I have tried rebuilding the bcd with bootrec /rebuildbcd, which returns Total identified windows installations. [1] D:/Windows Add installation to boot list? Yes(Y)/No(N)/All(A): I type “y” and click enter but it responds with The system cannot find the path specified. I have tried using the automatic fix tool but it does not work. I have tried using the repair from drive feature but that didn’t work either CPU: i7-5820k Memory: 16GB 2400mhz

    Boot into another system like Windows PE or Windows To Go, then mount the boot partition and use `bcdboot` to generate boot files again. – iBug Aug 27 '18 at 18:01

When I run into such issues (damaged or deleted BCD), I use a USB flash drive to boot into Windows PE or sometimes Windows To Go with my portable hard drive. In that environment, I mount both the system partition and boot partition, open Command Prompt and run:

bcdboot D:\Windows -s E:

Where D and E are system and boot (active partition on MBR, or ESP on GPT), respectively.

Usually that's all I do, and when I reboot the system installed on D: boot normally.

  • After trying many other things that I couldn't get working, this saved me. Cloned my Windows to a new NVMe drive and it worked fine for a day, then it wouldn't boot. I had to assign a letter to the boot partition and it worked like a charm. Thank you so much! – MC10 Jun 17 '19 at 08:20

    In case the ESP is not mounted automatically, you can use [mountvol](https://docs.microsoft.com/en-us/windows-server/administration/windows-commands/mountvol): `mountvol E: /s` – Hermann Dec 03 '19 at 19:07

    @Hermann Or use DiskPart: `ASSIGN LETTER E` after selecting the partition (volume). – iBug Dec 04 '19 at 04:19
