    How to clean up BCD entries? Rebuild the BCD?


    I have a number of bogus entries in BCD.
    Plus I cloned my primary Win10-1903 SSD to create a multiboot system, ran EasyBCD and that's what added all these fake entries. On top of that, it sometimes has trouble booting, I have to hit Cntrl-Alt-Delete to restart the boot process.

    I think something is corrupt in the BCD, or all these bad entries among good ones.

    I want to try this, can someone explain what exactly it does.


    bootrec /rebuildbcd

    :)

    BCD File Rebuild and BIOS

    Our IT department updated my pc to 1803 not realizing that I have an X299 motherboard and a Samsung NVME SSD boot drive. I came in the next day to get the BCD File error BSOD with error code 0xc000098 (a known bug but not fixed a year after discovery).
    Our IT department looked up this issue and decided to rebuild my BCD file and was (we thought) successful implementing this solution. My pc then booted from the previous NVME SSD drive. I had migrated my OS from the 256GB SSD to a new 500gb SSD, both NVME.
    No troubles for a year booting from the 500gb disk and now it boots from the old 256gb drive which I did not wipe on purpose. I boot into the UEFI ASUS bios on the pc and the boot order configuration only lists one option for position 1 to 4. Before each position
    listed each bootable device. First of all why in the world would a Windows update and BCD file rebuild screw with the BIOS and second how do I get the proper C: drive boot with to way to change the boot order in the BIOS?

    Windows 10 BCD Rebuild

    So recently my laptop ran in to a Boot BCD error (0xc0000034) and I looked in to fixes for it and was about to reset windows before coming accross a tutorial on how to rebuild the BCD.

    I'm currently on the command prompt after entering the bootrec /rebuildbcd and have this:
