    Windows 10 Can't boot, error 0xc000000f,\Boot\BCD not found.


    Hello forumers. Yesterday I removed dual booting Linux and after that my Windows 10 won't boot up. I have tried everything. The cmd commands: bootrec /FixMbr; bootrec /FixBoot; bootrec /RebuildBcd; Bcdboot commands and everything. Then I tried Refreshing PC what says: Drive where Windows is installed is locked. Please unlock it.....
    Startup repair just scans for a short periood and then says: Couldn't fix the problem. I can't Access normal Recovery options, so I'm using a recovery flash drive. I have tried several Live CDs but none of them won't fix the problem. I can access the UEFI Bios, but idk what to change there. I've searched hours for solution. I don't want to fresh install Windows, unless it's the only option, because it contains importnant data. Please reply

    Maybe there is a better solution, but if your hard disk has enough space, you could try to install Windows 10 again in a second partition. Start Windows 10 Setup and then shrink the current partition at about 15-20GB to make room for the second installation. Then install Windows 10 to the second partition. This should reinstall the Windows Boot Loader and add an entry to boot your old Windows installation as well. See if you can boot to your original Windows 10 installation. If you do, you can remove the boot entry for the new installation (careful to remove the right one!) and then delete the second partition and expand the first to take all space again. Not a convenient solution, but it would save you the trouble of taking a backup and installing all your applications from scratch!

    Ty for replying. I'll try that now. But I got 1 question. If I install new Windows on new partition and after that delete the new partition with new Windows, wouldn't the bootloader go broken again? (Sorry for bad english)

    The boot loader should be installed on the boot partition (first), so deleting the other partition should not pose a problem.

    Ok, so I installed the new Windows 10 on new partition. But for some reason it didn't create a new boot entry for my old Windows. So I guess I have to create it myself. Atleast I can access my computer now. But do you know any cmd command or program that can create new boot entries for Windows 10? I know there is a program called EasyBCD, but that doesn't support Windows 10 yet. Please advise!

    What about VisualBCD (haven't tried it myself)? Maybe there are others as well. Google for bcd alternative.

    Nice, I finally managed to fix it. I found an usefool tool called Dual-boot Repair Windows 10 which fixed my bootloader and old Windows 10 entry showed up. I started old Windows up and it was working with all files. So big thanks to you spapakons for helping me figure this out. Now I will delete the partition with new Windows 10 and hope everything will be fine.
